If it did, no one would ever install such heaters because it would be cost prohibitive. A manual gas shutoff valve located within 6 feet of the unit meets the intent of the code and another valve at the floor level is not required.This valve is there for servicing of the appliance.See definition of Valve, appliance shutoff.

We have made no independent effort to verify the accuracy of this information nor have we conducted a review beyond the scope of your question.

Olympic Ave Arlington, WA 98223 Code Reference: IFGC Code Edition: 2009 Code Section: 409.1.3 and 409.5.1 page 71 Questions: Section 409.1.3 requires access to shut-off valves for operation. Section 409.5.1 requires that the shut-off valve be located within 6 feet of the appliance and be provided with access. My question refers mainly to the installation of Unit Heaters, where they are typically installed at the ceiling level of F &S occupancies without access. Do these sections allow a shut-off valve to be installed within 6 feet of the appliance, upstream of the connector and also provide a shut-off valve at the floor level for access or is a permanent platform or ladder always required to provide "access" to the appliance? Is it code compliant to simply have a shut-off valve within 6 feet of the appliance in this scenario.

WARNING: If touched, the vent pipe and internal heater surfaces Consult the Venting that are accessible from outside the heater will cause burns. Manual for this heater Suspend the heater a minimum of 5 feet (1.5M) above the floor. before malting final determination. For best results, the heater should be placed with certain rules in mind. In general, a unit should be located from 8 to 12 feet(2.4-3.7M)above the floor. Units should always be arranged to blow toward or along exposed wall surfaces, if possible. Where two or more units are installed in the same room, a general scheme of air circulation should be maintained for best results. Suspended heaters are most effective when located as close to the working zone as possible, and this fact should be kept in mind when determining the mounting heights to be used. However, care should be exercised to avoid directing the discharged air directly on the room occupants. Partitions, columns, counters,or other obstructions should be taken into consideration when locating the unit heater so that a minimum quantity of airflow will be deflected by such obstacles. When units are located in the center of the space to be heated, the air should be dis- charged toward the exposed walls. In large areas,units should be located to discharge Form WDA,PIN 1A5673 R16,Page 5 r Y 2.0 Unit Heater 2.2 Location Recommendations (cont'd) Location air along exposed walls with extra units provided to discharge air in toward the center (cont'd) of the area. At those points where infiltration of cold air is excessive, such as at entrance doors and shipping doors, it is desirable to locate the unit so that it will discharge directly toward the source of cold air from a distance of 15 to 20 feet(4.6-6.1 M). CAUTION: Do not locate the heater where it may be exposed to water spray, rain, or dripping water. For a location where dirt, dust,-or-other airborne contaminants are present in the indoor environment, it is recommended to install a separated-combustion unit, Model UDAS, that uses outside air for combustion. Using a separated-combustion unitwill reduce the build-up of contaminants on the burner.Any buildup on the burner will adversely affect the combustion process. Hazards of Chlorine - The presence of chlorine vapors in the combustion air of gas-fired heating equipment applies to location presents a potential corrosion hazard. Chlorine found usually in the form of freon or of Model UDAS degreaser vapors, when exposed to flame will precipitate from the compound, and go heater with regard to into solution with any condensation that is present in the heat exchanger or associated combustion air inlet parts. The result is hydrochloric acid which readily attacks all metals including 300 grade stainless steel. Care should be taken to separate these vapors from the combus- tion process. This may be done by wise location of the unit vent and combustion air terminals with regard to exhausters or prevailing wind directions. Chlorine is heavier than air. Keep these facts in mind when determining installation location of the heater in relation to building exhaust systems. 3.0 Uncrating and 3.1 Uncrating and Inspecting Preparation This unit was test operated and inspected at the factory prior to crating and was in operating condition. If the heater has incurred any damage in shipment,-document-the- -- damage with the transporting agency and contact an authorized Reznor Distributor. If you are an authorized Distributor, follow the FOB freight policy procedures as pub- lished by Thomas & Betts for Reznor products. Check the rating plate for the gas specifications and electrical characteristics of the heater to be sure that they are compatible with the gas and electric supplies at the installation site. 3.2 Preparing for Installation Read this booklet and become familiar with the installation requirements of your par- ticular heater. If you do not have knowledge of local requirements, check with the local gas company or any other local agencies who might have requirements concerning this installation. Before beginning, make preparations for necessary supplies, tools, and manpower. IMPORTANT: Shipping brackets are attached with cabinet screws. When remov- ing shipping brackets, re-insert ALL screws into the cabinet. 3.2.1 Field-Installed Parts If the installation includes optional vertical louvers, downturn nozzle, ceiling mounting bracket, hanger kit, high altitude kit, multiple heater control, sensor for DDC control, and/or stepdown transformer, install these options before the heater is suspended. Complete instructions:are in this-form or in the option package; option packages are shipped separately. Other shipped separate items could include a vent cap(Option CC for UDAP);a vent/ combustion air kit (Option CC2 or CC6 for UDAS); a manual gas valve; a thermostat bracket kit; a thermostat; and/or a thermostat guard. Be sure all options ordered are at the installation site. High Altitude Kit, Option DJ20 or DJ21 If the heater is being installed at an elevation above 2000 ft(610M), the input rate will have to be derated. This is done by adjusting the valve outlet pressure. Form WDA,P/N 195673 R16,Page 6 i �+ i i In addition, if the heater is being installed at an altitude above 6000 ft (1830M), the pressure switch will have to be changed. If ordered with the unit as Option DJ20 or DJ21, the pressure switch is shipped separately for field installation. Gas valve adjustment Adjusting the valve outlet pressure is done after the heater is in operation; follow the for high altitude can instructions in Paragraph 6.1. Capacities and inputs for derated units are also listed in only be done after Paragraph 6.1. heater is operating; If the pressure switch needs to be changed, do that before the heater is operated; fol- see Paragraph 6.1. low the instructions in FIGURE 2.

All piping must be in accordance with requirements outlined in the National Fuel Gas Code ANSI/Z223.1a (latest edition) or CSA-B149.1 and 13149.2 (See Paragraph 2). Gas supply piping installation should conform with good practice and with local codes. Support gas piping with pipe hangers, metal strapping, or other suitable material; do not rely on the heater to support the gas pipe. The heater is orificed for operation with natural gas having a heating value of 1000 (± 50)BTU per cubic ft or propane gas with a heating value of 2500(± 100)BTU per cubic ft. If the gas at the installation does not meet these specifications, consult the factory for proper orificing. Pipe joint compounds (pipe dope)shall be resistant to the action of liquefied petroleum gas or any other chemical constituents of the gas being supplied. Install a ground joint union and manual shutoff valve upstream of the unit control sys- tem, as shown in FIGURE 9. Installation of a trap with a minimum 3" (76mm) drip leg is required. The unit is equipped with a nipple that extends outside the cabinet.The gas connection is either 1/2"or 3/4". Leak-test all connections by brushing on a leak-detecting solution.

The requirements for combustion and ventilation air depend upon whether the unit is located in a confined or unconfined space.An"unconfined space"is defined as a space whose volume is not less than 50 cubic feet per 1000 BTUH of the installed appliance. Under ALL conditions, enough air must be provided to ensure there will not be a negative pressure condition within the equipment room or space. WARNING: Model UDAP and UDAP-CV power-vented unit heaters are designed to take combustion air from the space in which the unit is installed and are not designed for connection to outside combustion air intake ducts.

In addition, the installer should be aware of any CAUTION: Route local ordinances or gas company requirements that might apply, wires so that they do CAUTION: If any of the original wire as supplied with the appliance not contact the flue must be replaced, it must be replaced with wiring material having a wrapper or venter temperature rating of at least 105°C, except for limit control, flame housing. rollout, and sensor lead wires which must be 150°C. See Hazard Levels, page 2. Form WDA,P/N 195673 R16,Page 16 i 7.2 Supply Wiring Check the rating plate on the heater for the supply voltage and current requirements. A dedicated line voltage supply with disconnect switch should be run directly from the main electrical panel to the heater.All external wiring must be within approved conduit and have a minimum temperature rise rating of 60°C Conduit must be run so as not to interfere with the heater access panel. If the installation requires a stepdown trans- former(Option CG),follow the instructions shipped with the option package for attach- ing the transformer to the heater. The electrical supply enters at the rear of the heater (See FIGURE 13). Model UDAS includes a built-in disconnect switch (20A @ 115V; 10A @ 230V Rating). Model UDAS supply wiring connects to leads located inside a sealed electrical box. To maintain the sealing feature of the electrical box, always replace the cover plate. Model UDAP sup- ply wiring connects directly to leads on the integrated circuit board. The circuit board (See FIGURE 12)is located inside on the bottom of the control com- partment. The circuit board is polarity sensitive. It is advisable to check the electrical supply to be certain that the black wire is the "hot'wire and that the white wire is the neutral wire.The supply connection made to"L1"on the circuit board must be the"hot' wire.

On Model UDAP, the switch Wiring (cont d) is a single pole/normally open device which closes when a negative pressure is sensed 7.5 Electrical in the venter housing. On Model UDAS, the switch senses the differential pressure Operating between the negative pressure in the venter housing and the pressure in the cabinet. (For switch location, see FIGURE 18, page 30.) Components On startup when the heater is cold,the sensing pressure is at the most negative level, and as the heater and flue system warm up,the sensing pressure becomes less nega- tive. After the system has reached equilibrium (about 20 minutes), the sensing pres- sure levels off. If a restriction or excessive flue length or turns cause the sensing pressure to be out- side the switch setpoint, the pressure switch will function to shutoff the main burner. The main burner will remain off until the system has cooled and/or the flue system resistance is reduced. The Tables on the left below list the approximate water column negative pressure readings and switch setpoints for sea level operating conditions for Model UDAP and Model UDAP-CV heaters. The Table on the right lists the approximate water column differential pressure readings and switch setpoints for sea level operating conditions for Model UDAS heaters. DANGER: Safe operation of this unit requires proper venting flow. NEVER bypass combustion air proving switch or attempt to operate the unit without the venter running and the proper flow in the vent system. Hazardous conditions could result.

The con- trol is factory set and is non-adjustable. If the setpoint is reached, the limit control will interrupt the electric supply to the gas valve. This safety device provides protection in the case of motor failure or lack of airflow due to a restriction at the inlet or outlet. (For location, see FIGURE 18, page 30.) CAUTION: The auto reset limit control will continue to shut down the heater until the cause is corrected. Never bypass the limit control; hazardous conditions could result. See Hazard Intensity Levels, page 2. Form 1-UDA,P/N 195673 R16,Page 20 f Sizes 30-125 are equipped with a temperature activated manually reset flame rollout switch.The flame rollout switch is located at the top of the burner assembly. It is factory set and is non-adjustable. If the setpoint is reached, the flame rollout acts to interrupt the electric supply to the gas valve. If the flame rollout switch activates, identify and cor- rect the cause before resetting the switch. Refer to the Maintenance Section, Paragraph 10.2.10, for information on probable causes and instructions on resetting the flame rollout switch. (For location, see FIGURE 18, page 30.) DANGER: If the manual reset flame rollout switch activates, identify and correct the cause before resetting the switch. Never bypass the flame rollout switch; hazardous conditions could result. See Hazard Intensity Levels, page 2. 7.5.3 Door Switch - All sizes of Model UDAS heaters are equipped with a door switch which prevents Model UDAS only the heater from operating when the service door panel is open. The service panel of a Model UDAS is equipped with a pliable gasket material that fully seals the door to provide added protection from building air entering the combustion zone of the heater. (For switch location, see FIGURE 18, page 30.) 7.5.4 Gas Valve The main operating gas valve is powered by the 24-volt control circuit through the ther- mostat and safety controls. The main control valve is of the diaphragm type providing regulated gas flow preset at the factory. (For location, see FIGURE 18, page 30.) WARNING: The operating valve is the prime safety shutoff. All gas supply lines must be free of dirt or scale before connecting the unit to ensure positive closure. See Hazard Levels, page 2. 7.5.5 Fan Motor The fan motor-is-equipped with thermal overload protection-of-the-automatic reset type. Should the motor refuse to run, it may be because of improper current characteristics. Make certain that the correct voltage is available at the motor. NOTE: If the unit is equipped with an optional totally enclosed motor or optional volt- age,the horsepower may be larger than the standard motor. Refer to the motor name- plate to verify horsepower. 7.5.6 Venter Motor The venter motor is assembled to the venter wheel and operates to provide combus- tion airflow. Operation is controlled by the ignition control module (circuit board); refer to ignition system in Paragraph 8.3. 8.0 Controls and 8.1 Thermostat Operation Use either an optional thermostat available with the heater or a field-supplied 24-volt thermostat. Install according to the thermostat manufacturer's instructions, paying par- ticular attention to the requirements regarding the location of the thermostat. Make sure that if there is a heat anticipator setting on the thermostat,it is set at 0.6 amps (or in accordance with the amperage value noted on the heater wiring diagram). Make thermostat connections at the terminal strip on the back of the heater. The strip has four terminals, R, G, W1, and W2; refer to the wiring diagram. IMPORTANT: All units MUST be operated bya 24-volt thermostat. Never use a line voltage disconnect switch as a means of operating the heater. Operating Model Sizes 30-125 by means other than a 24-volt thermostat may result in the flame rollout switch tripping. Unit Mounted Thermostat,Option CM3 - If the heater was ordered with Option CM3, a kit for mounting the thermostat on the rear of the heater is shipped separately. Follow the instructions in the option package to attach the bracket. Select a snap-action thermostat when using the unit mounted thermostat bracket. Do not use a mercury switch thermostat because the vibration may cause excessive unit cycling. Be careful with the thermostat leads; shorting the thermostat wires to a metal surface will cause the transformer to fail. Form WDA,P/N 195673 R16,Page 21 i i '8.0 Controls and Multiple Heater Control, Option CL31 and Option CL32 - If the heater was ordered Operation with a multiple heater control option, one thermostat can be used to control up to six (cont'd) heaters. The option includes a 40VA transformer that replaces the standard trans- former in the "controlling" unit and a relay assembly that attaches to the additional 8.1 Thermostat unit. Option CL31 provides for control of two heaters. If control of additional heaters is (cont'd) desired (up to six total), Option CL32 which is the relay assembly only must be added to each additional heater. The option packages are shipped separately and include complete instructions on installation and wiring. 8.2 DDC Controls, If the heater was ordered with Option D10 or D14, it is equipped with a Novar Minio Options D10 and control module.The Novar control with its accompanying relays and power transformer D14 are mounted in the control compartment of the unit. See FIGURE 15A. This control offers a wide variety of input and output points that can be configured to meet a wide range of building management.applications. User-selectable input types are Thermis- tor, 4-20 milliamp, 1-5 volts, or digital.

The Cycle Operating control checks to see that the limit switch is closed and the pressure switch is open. If Sequence the limit switch is open, the control responds as defined in the "Abnormal Heat Cycle, Limit Switch Operation". If the pressure switch is closed, the control will do four flashes on the green LED and wait indefinitely for the pressure switch to open. If the pressure LED lights are visible switch is open, the control proceeds to prepurge. through viewport on 2)Prepurge-The control energizes the venter motor and waits for the pressure switch Model UDAS. Remove to close. If the pressure switch does not close within 30 seconds of the venter motor door panel to view LED energizing, the control will do two flashes on the green LED.The control will leave the lights on Model UDAP. venter motor energized indefinitely as long as the call for heat remains and the pres- sure switch is open. When the pressure switch is proven closed, the control begins the prepurge time. If flame is present any time while in prepurge, the prepurge time is restarted. If flame is present long enough to cause lockout,the control responds as defined in"Fault Modes, Undesired Flame". The control runs the venter motor for a 20 second prepurge time,then proceeds to the ignition trial period. 3) Ignition Trial Period - The control energizes the spark and main gas valve. The venter remains energized. If flame is sensed during the first 16 seconds, the spark is de-energized and the control proceeds to heat fan/blower on delay. If flame has not been sensed during the first 16 seconds, the control de-energizes the spark output and keeps the gas valve energized for an additional one second flame proving period. If flame is not present after the flame proving period, the control de-energizes the gas valve and proceeds with ignition re-tries as specified in "Abnormal Heat Cycle, Ignition Retry". If flame is present, the control proceeds to the fan/blower on delay. Form WDA,P/N 195673 R16,Page 23 ` 8.0 Controls and Normal Heat Cycle Operating Sequence (cont'd) Operation 4) Fan/Blower On Delay - The control waits for 30 seconds from the time the gas (Cont'd) valve opened and then energizes the fan/blower motor. The gas valve and venter motor remain energized. The control proceeds to steady heat mode. 8.3 Ignition System 5) Steady Heat- Control inputs are continuously monitored to ensure limit and pres- (cont'd) sure switches are closed,flame is established,and the thermostat call for heat remains. When the thermostat call for heat is removed, the control de-energizes the gas valve and begins post-purge and fan/blower off delay timing. 6)Post Purge-The venter motor output remains on for a 45-second post-purge period after the thermostat is satisfied. 7) Fan/Blower Off Delay-The fan/blower motor is de-energized after a fan/blower off delay(120 seconds).Timing begins when the thermostat is satisfied. Abnormal Heat Cycle Interrupted Thermostat Call for Heat- If the thermostat demand for heat is removed Functions before the flame is recognized, the control will run the venter motor for the post purge period and de-energize all outputs. If the thermostat demand for heat is removed after successful ignition, the control will de-energize the gas valve, run the venter motor through post purge, and run the fan/ blower motor on heat speed for the selected delay off time. Ignition Retry-If flame is not established on the first trial for ignition period,the control de-energizes the gas valve and the venter motor remains energized for an inter-purge period of 10 seconds. The spark and gas valve are then re-energized, and the control initiates another trial for ignition. If flame is not established on the second trial for ignition, the control de-energizes the gas valve, energizes the fan/blower motor on heat speed, and venter motor remains energized. The fan/blower motor is shut off after 120 seconds. When the fan/blower motor de-energizes, the spark and gas valve are re-energized and the control initiates another trial for ignition. (This fan delay is self-healing feature for an open auxiliary limit switch). If flame is not established on the third trial for ignition period, the control de-energizes the gas valve, and the venter motor remains energized for an inter-purge period of 10 seconds. The control then re-energizes the gas valve and spark and initiates another trial for ignition. If flame is not established on the fourth trial for ignition (initial try plus 3 re-tries), the control de-energizes the gas valve and goes into lockout.The control goes to one flash on the green LED to indicate ignition failure lockout. Limit Switch Operation -The limit switch is ignored unless a call for heat is present (W energized). If the limit switch is open and a call for heat is present, the control de- energizes the gas valve and turns the fan/blower motor on heat speed and runs the venter motor. When the switch re-closes or the call for heat is lost, the control runs the venter motor through post purge and runs the blower/fan motor through the selected fan off delay. The control will return to normal operation after fan off delay is completed. Pressure Switch - If the pressure switch opens before the trial for ignition period, the venter motor will run through the pressure switch recognition delay (2 seconds), the gas valve will be de-energized, and the venter motor will run through the postpurge time. The control will re-start the heat cycle at the pressure switch proving state if the call for heat still exists. Pressure switch opening for less than 2 seconds during the trial for ignition period shall not interrupt the heat cycle. (Gas valve will de-energize while the pressure switch is open.) If the pressure switch opens after a successful ignition, the control will de-energize the gas valve. If flame is lost before the end of the 2 second pressure switch recogni- tion delay, the control will respond to the loss of flame. If the pressure switch remains open for 2 seconds and the flame remains,the control de-energizes the gas valve,the venter motor runs through post-purge, and the fan/blower motor runs on heat speed Form WDA,P/N 195673 R16,Page 24 through the selected fan off delay. When the fan off delay is over, the fan/blower motor is de-energized, and a heat cycle is begun if the call for heat still exists. Continuous Fan When the thermostat calls for continuous fan(G)without a call for heat,the fan motor is Operation energized after a .25 second delay. NOTE:This brief on delay is to allow the"G"termi- nal to energize slightly before"Y"and an external changeover relay to switch from "G" to "W" without causing momentary glitches in the fan/blower output. The fan remains energized as long as the call for fan remains without a call for heat. If a call for heat(W)occurs during continuous fan, the fan/blower will de-energize. A call for fan is ignored while in lockout. Fault Modes Undesired Flame - If flame is sensed longer than 20 seconds while the gas valve is de-energized,the control shall energize the venter motor and fan/blower motor on heat speed. When flame is no longer sensed, the venter motor will run through postpurge, and the fan/blower motor will run through the selected heat fan off delay time. The control will do a soft lockout, but will still respond to open limit and flame. The FLAME (yellow) LED shall flash rapidly when lockout is due to undesired flame. Gas Valve Relay Fault-If the control senses the gas valve as energized for more than one second when the control is not attempting to energize the gas valve, or the gas valve is sensed as not energized when it is supposed to be energized,then the control will lockout with green LED off. The control assumes either the contacts of the relay driving the gas valve have welded shut, or the sensing circuit has failed. The venter motor is forced off to open the pressure switch to stop gas flow unless flame is pres- ent. If the gas valve was sensed as closed when it should be open, and has not de-ener- gized after the venter motor was shutoff for 15 seconds, then the venter motor is re- energized to vent the unburned gas. Lockout Soft Lockout - The control shall not initiate a call for heat or call for continuous fan while in loc out. The control will still respond to an open limit and undesired flame. Lockout shall automatically reset after one hour. Lockout may be manually reset by removing power from the control for more than one second or removing the thermostat call for heat for more than one and less than 20 seconds. Hard Lockout-If the control detects a fault on the control board,the status LED will be de-energized, and the control will lockout as long as the fault remains.A hard lockout will automatically reset if the hardware fault clears. Power Interruption-During a momentary power interruption or at voltage levels below the minimum operating voltage(line voltage or low voltage)the system will self-recover without lockout when voltage returns to the operating range. Power interruptions of less than 80mS shall not cause the control to change operating states. Power interruptions greater than 80mS may cause the control to interrupt the current operating cycle and re-start.
