INSTALLING A MECHANICAL GAS VALVE KIT MRM, MRM II OR PRM
December 2008 Section 4 Installation Page 4 – 21
Amerex Restaurant Fire Suppression System (EX 4658)
The gas shut off valve to be converted to a “pull to close” type
should be located where it can be easily accessed for
resetting, maintenance and service.
This kit is designed to allow certain specified gas shut-off
valves to be interconnected to an Amerex Restaurant
System. It is not intended for repair of damage or
inoperable gas shut-off valves or to be used with
restaurant systems other than an Amerex restaurant
system.
1. Insure that the MRM / MRM II / PRM have been locked
out properly, refer to the Installation Section.
WARNING: VERIFY THAT THE MAIN GAS SUPPLY
HAS BEEN SHUT OFF PRIOR TO INSTALLING THE
GAS SHUT OFF VALVE. GAS VALVE
INSTALLATION SHOULD BE PERFORMED BY A
QUALIFIED, LICENSED CONTRACTOR.
2. Visually inspect the gas shut-off valve stem for
cleanliness and damage. Replace the gas shut-off
valve if the stem appears damaged or if it will not
operate properly.
3. Install the conduit connector as shown in figure 1.
4. Install the outlet box (P/N 13626) using the jam nut
(P/N 13625) and the washer (P/N 13624).
5. Install the cotter pin (P/N 08292) through the gas shut-
off valve stem and hole that corresponds to the size of
the valve (refer to figures 1). Bend the tabs of the
cotter pin over to secure it in place. Be sure that the
tabs do not interfere with the operation of the holder.
6. Install the necessary ½” EMT conduit, corner pulleys
(P/N 12309 or 16444), tee pulleys (P/N 12506) and
cable (P/N 12553) to connect the shut off valve to the
MRM. For gas shut off valve cable limitations and
installation instructions see the Design and Installation
sections.
7. Insert one end of the cable through the crimp, through
the hole in the rear of the holder then back through the
crimp and compress the crimp to secure it in place.
8. To install, set and test the piston assembly at the other
end of the cable, refer to the Installation and Testing
and Commissioning sections under “Installing a
Mechanical Gas Valve”.
9. After testing the actuation of the gas shut off valve,
insure that all components of the system are reset.
Place the cover on the outlet box and secure it in
place.
