Do not install the thermostat where it may be influenced by any of the following: â€¢ Drafts, or dead spots behind doors, in corners, or under cabinets. â€¢ Hot or cold air from registers. â€¢ Radiant heat from the sun. â€¢ Light fixtures or other appliances. â€¢ Radiant heat from a fireplace. â€¢ Concealed hot or cold water pipes, or chimneys. â€¢ Unconditioned areas behind the thermostat, such as an outside wall. Consult the instructions packaged with the thermostat Figure 2A for mounting instructions and further precautions. Combustion & Ventilation Requirements WARNING TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH, Figure 2B SUFFICIENT FRESH AIR FOR PROPER COMBUSTION AND VENTILATION OF FLUE GASES MUST BE SUPPLIED. MOST HOMES REQUIRE OUTSIDE AIR BE SUPPLIED INTO THE FURNACE AREA. Improved construction and additional insulation in buildings have reduced heat loss by reducing air infiltration and escape around doors and windows. These changes have helped in reducing heating/cooling costs but have created a problem supplying combustion and ventilation air for gas fired and other fuel burning appliances. Appliances that pull air out Figure 2C of the house (clothes dryers, exhaust fans, fireplaces, etc.) increase the problem by starving appliances for air. House depressurization can cause back drafting or improper combustion of gas-fired appliances, thereby exposing build- ing occupants to gas combustion products that could include carbon monoxide. If this furnace is to be installed in the same space with other gas appliances, such as a water heater, ensure there is an adequate supply of combustion and ventilation air for the other appliances. Refer to the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 or CAN/CSA B149.1- 15 Installation Codes or applicable provisions of the local building codes for determining the combustion air require- ments for the appliances. Figure 2D Most homes will require outside air be supplied to the fur- nace area by means of ventilation grilles or ducts connecting directly to the outdoors or spaces open to the outdoors such as attics or crawl spaces. 10 Recommended Installation Positions 3.

All furnace models installed horizontally require the trap to be relocated. Many drain hoses have a builtâ€“in grommet which will provide a cabinet seal when installed. See instructions below for your model and installation position. NOTE: Both sides of the drain trap must be primed prior to initial furnace start up. 18 Field Supplied Drain WARNING Drain the furnace and air conditioning coil if applicable, in EDGES OF SHEET METAL HOLES MAY BE SHARP.

While the furnace is operating at high fire rate, time and record one complete revolution of the gas meter SUPPLY dial measuring the smallest quantity, usually the dial AIR that indicates 1/2 cu. ft. per revolution. You will use this number to calculate the quantity of gas in cubic ft. if the furnace would consume if it ran steadily for one hour (3600 seconds). 3. If the 1/2 cu. ft. dial was used, multiply your number x 2. EXAMPLE: If it took 23 seconds to complete one revolution of the 1/2 ft. dial (23 x 2 = 46). This tells us that at this rate, it would take 46 seconds to consume one cu. ft. of gas. 3600 / 46 = 78. RETURN AIR This tells us that in one hour, the furnace would consume 78 cu. ft. of gas. Temperature Rise Measurement The typical value range for 1 cu. ft. of natural gas is around Figure 45 1000 BTU. Check with your gas utility, if possible.

Temperature Rise Temperature rise must be within the range specified on the unit rating plate. An incorrect temperature rise may result in condensing in or overheating of the heat exchanger. An airflow and temperature rise table is provided in the Specifi- cation Sheet applicable to your model. Determine and adjust temperature rise as follows: 1. Operate furnace with burners firing for approximately ten minutes. Ensure all registers are open and all duct dampers are in their final (fully or partially open) position. 2. Place thermometers in the return and supply ducts as close to the furnace as possible. Thermometers must not be influenced by radiant heat by being able to â€œseeâ€ the heat exchanger. 33 Airflow Table LOW STAGE COOLING AIFLOW HIGH STAGE COOLING AIFLOW EXTERNAL STATIC PRESSURE, (INCHES
