ERSTANDING EQUIVALENT PIPING
■ Linear piping is the actual length of straight pipe used on either the main supply line or a
branch.
■ Equivalent piping is equal to the total linear pipe used on either the main supply or a
branch plus the equivalent length of any fittings used on either the main supply line or a
branch. SPP the Figure below.
Equivalent Piping = (Linear Piping) + (Total Equivalent Length of fittings Used)
* All pipe fittings develop a pressure loss, which can be equated to the loss through a
specific length of straight pipe. This loss is the equivalent length of the fitting. See the

The Model NL-A nozzle is a one (1) flow point nozzle that
has been developed to protect the plenum section of the
exhaust hood. Only one (1) Model NL-A nozzle can be used
on a single plenum branch. A single Model NL-A can protect
a plenum (with single or V-Bank filters) with rectangular
dimensions of 8' x 4' or less. Larger plenums can be protect-
ed by dividing the hazard area so that each nozzle protects
an area of 8' x 4' or less (see Figure 3-3).

MOUNTING
The Model EN-MCU and/or EN-S Enclosure must be securely anchored to the wall using bolts or lag screws. The wall to
which the enclosure is attached must be sufficiently strong. The enclosure should never be fastened to dry wall or similar
material. If this type of wall is encountered, studs must be located and the enclosure fastened to them.
Three (3) center mounting holes allow either enclosure to be mounted on a single stud. Four (4) corner mounting holes are
also available. See Figure 4-24.
FUSIBLE LINK DETECTOR INSTALLATION
The Model EN-MCU Enclosure can support a fusible link detection system. The Model EN-S Enclosure cannot support a
fusible link detection system and must be used in conjunction with the Model EN-MCU Enclosure or a Model MCH/ECH
Control Head.
After mounting the enclosure, the fusible link line can be installed. The first step to installing the fusible link line is to install
the detector brackets. These brackets must be installed in the plenum area of the ventiiation hood over all protected appli-
ances and in each duct. See Chapter III for detector placement guidelines. Connect the fusible link brackets together using
1/2" EMT conduit and the conduit connectors supplied in the detector kit (Model FLK-1/1A). Pyro-Chem corner pulleys must
be used whenever a change in conduit direction is necessary. The conduit is connected to the enclosure through a top
knockout.
See Fusible Link Detector Installation Section of this chapter (pages 4-4 - 4-6) for fusible link installation guidelines. Before
attaching the stainless steel cable to the fusible link line ratchet wheel, it must be run below the fusible link line pulley in the
enclosure. See Figure 4-25.

SETTING THE MODEL EN-MCU
After the last link in the series is connected, the cable should be fed through the conduit back to the Model EN-MCU. It must
be fed under the fusible link line pulley and through the hole in the fusible link ratchet wheel. The line must then be crimped,
and the crimp positioned inside the ratchet wheel.
NOTE
Crimps must always be used in conjunction with two (2) cable lengths. Loops are the accepted method of connecting
the cable to mechanical components. The crimp must never be used on a single cable.
Crimps must always be used in conjunction with two (2) cable lengths. Loops are the accepted method of connecting the
cable to mechanical components. The crimp must never be used on a single cable.
The fusible link line can now be put into a set position by tensioning the fusible link line. This is accomplished by using a
3/4" socket on the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the spring
plate is parallel to the top of the enclosure. The fusible link line is now in a set position.
Once the fusible link line is set, the Model EN-MCU Enclosure can be placed in the set position. To set the Model EN-MCU,
the slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide
plate. Continue moving the slide plate to the left until the latching arm is in the locked position. Insert the pull pin into the
hole in the slide plate above the latching arm. This will loci:the control mechanism in the set position, eliminating accidental
actuation during the rest of the installation procedure. See Figure 4-25.
REMOTE PULL STATION INSTALLATION
The Model RPS-M Remote Mechanical Pull Station is used for remote manual actuation of the Model EN-MCU. It is to be
located near an exit in the path of egress from the hazard area no more than five feet above the floor.
The Pull Station is connected to the Model EN-MCU using 3/64" or 1/16" diameter stainless steel cable. The cable enters the
Model EN-MCU through a knockout in the top of the enclosure. See Figure 4-25.
See Remote Pull Station Installation Section of this chapter (pages 4-8/9) for remote pull station installation guidelines.

+ GAS SHUT-OFF VALVE INSTALLATION
The Model EN-MCU can be used to operate a mechanical gas shut-off valve. This valve is located in the fuel gas supply line
to the cooking appliance(s). The valve body has an arrow which indicates direction of gas flow through the valve. The gas
shut-off valve is spring loaded and requires five pounds of force to hold it open. This force is supplies by a 3/64" or 1/16"
diameter stainless steel cable that is connected to the Model EN-MCU.
After the valve is installed in the gas line, 1/2" conduit must be run from the top center knockout of the gas valve box to the
top or bottom knockout in the enclosure. See Figure 4-24, A Pyro-Chem corner pulley is used wherever a change in conduit
direction is required.
Gas Valve Cable Run Limitations
Maximum length of cable: 50 feet
Maximum # of pulleys: 15
Remove the gas valve cover and thread the stainless steel cable through the conduit back to the Model EN-MCU. If the
cable enters the enclosure through the bottom knockout, the cable must be run over the gas valve line pulley (see Figure 4-26).
If the cable enters the enclosure through the top knockout, the cable must be run under the gas valve line pulley (see
Figure 4-27). Thread the cable through the hole in the gas valve ratchet wheel. The line must then be crimped, and the
crimp positioned inside the center of the ratchet wheel.
CAUTION
The gas valve cable must always utilize the gas valve pulley and exit the top or bottom or the enclosure. The gas
valve cable cannot exit the side of the enclosure.
At the gas valve, loop the cable through the valve stem and secure it with the crimp provided (see Figure 4-18, page 4-10).
The gas valve line can now be put into a set position by applying tension to the gas valve line. This is accomplished by
using a 3/4" socket on the gas valve ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the gas
valve is fully open. Secure the gas valve cover plate to the gas valve box with the four (4) screws provided. The gas valve
line is now in a set position. See Figure 4-26 and/or Figure 4-27.

Three (3) knockouts are provided for Miniature Switch wiring. The upper right-side knockout must be used when the gas
valve line exits the bottom of the enclosure (see Figure 4-26). The lower right-side knockout must be used when the gas
valve line exits the top of the enclosure (see Figure 4-27).An additional knockout located on the top of the enclosure is also
provided (see Figure 4-24) and may be used in either situation.
CYLINDER INSTALLATION
1. Single Cylinder Installation - PCL-240/350.
The Model EN-MCU can be used for single cylinder installations. It can support either the Model PCL-240 or PCL-350 cylin-
der assemblies. The cylinder must be placed in the enclosure with the discharge port to the left. No additional mounting
bracket is required when the Model EN-MCU is used.
In order to actuate the agent cylinder from the Model EN-MCU's control mechanism, pneumatic tubing must be used to con-
nect the actuator to the valve cap assembly of the agent cylinder valve. A 1/4" NPT x 1/4", 450 flare type elbow is included
and must be installed in the actuator of the Model EN-MCU Enclosure. See Figure 4-28.

NOTE,
Pneumatic tubing used for cylinder actuation shall have an outside diameter of 1/4" with a minimum wall thickness of
1/32". This is commonly known as refrigeration-type copper tubing. All tubing fittings shall be of the 1/4", 45° flare type
conforming to SAE J513c. Compression type fittings are not acceptable.

The Model EN-S can be used in conjunction with the Model EN-MCU Enclosure or Model MCH/ECH Control Head for multi-
ple cylinder installations. A single Model EN-MCU can be used to pneumatically actuate a maximum of three (3) agent cylin-
ders. One (1) agent cylinder can be installed in the Model EN-MCU Enclosure; the additional agent cylinder(s) can either be
mounted in a Model EN-S Enclosure or with a Model MB-15 Mounting Bracket. When an enclosure is used, the cylinders
must be placed in the enclosure(s) with the discharge port to the left. No additional mounting bracket is required when a
cylinder is installed in the Model EN-MCU or EN-S Enclosure.
In order to actuate the agent cylinders from the Model EN-MCU, pneumatic tubing must be used to connect the EN-MCU
actuator to the valve cap assembly of each agent cylinder valve. Pneumatic tubing must be run from the actuator in the
Model EN-MCU to the Model EN-S(s) through the side knockout. A 1/4", 45' flare x 1/4", 450 flare x 1/4" NPT tee is included
with the Model EN-S and must be installed in the Model EN-MCU actuator. See Figure 4-29.
NOTE
Pneumatic tubing used for remote cylinder actuation shall have an outside diameter of 1/4" with a minimum wall thick-
ness of 1/32". This is commonly known as refrigeration-type copper tubing. All tubing fittings shall be of the 1/4", 45'
flare type conforming to SAE J513c. Compression type fittings are not acceptable.
A single Model EN-MCU can actuate a maximum of three (3) cylinders with up to 6' of copper tubing. A single Model EN-
MCU can actuate a maximum of two (2) cylinders with up to 8' of copper tubing.

SYSTEM CHECKOUT AFTER INSTALLATION
Before putting the system into service, all components must be checked for proper operation. During this checkout, assure
that the carbon dioxide pilot cartridge is not installed in the Model EN-MCU actuator. Remove the pull pin from the hole in
the slide plate.
To check satisfactory operation of the control mechanism, cut the terminal link or the "S" hook holding the link. This will
relieve all tension on the fusible link line and operate the control mechanism. The slide plate will have moved fully to the
right. The gas valve cable will have been released, causing the gas valve to close. Any auxiliary equipment connected to the
dry contacts of the soienold monitor and/or the Miniature Switch in the Mode: EfJ-MCU will have operated.
If any of these events fail to occur, the problem must be investigated and repaired.
Repair the terminal link and put the fusible link line back into the set position. This is accomplished by using a 3/4" socket on
the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the spring plate is parallel
to the top of the enclosure.
Once the fusible link line is set, the control mechanism can be placed in the set position. To set the control mechanism, the
slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate.
Continue moving the slide plate to the left until the latching arm is in the locked position. Once the control mechanism is set,
pull the pull handle on the remote pull station to assure that the control head operates. If the control mechanism operates
normally, the control mechanism can be reset as described above. Insert the pull pin into the hole in the slide plate above
the latching arm. Replace the pull station handle, pull pin, and nylon tie.
Assure that the gas valve is fully open by ratcheting the gas valve ratchet wheel.
CAUTION
Before screwing the carbon dioxide pilot cartridge into the actuator, ensure that the actuator has a Teflon 0-ring
installed.
Using a felt-tipped marker, write the date of installation in the gray area of the carbon dioxide pilot cartridge. Screw the car-
tridge into the Model EN-MCU actuator until hand-tight. Never use a wrench to tighten the cartridge into the actuator.
Remove the pull pin from the hole in the slide plate. Secure the Model EN-MCU/S cover with the screws provided.
