1. Make certain that regulated release assembly enclosure
cover is detached and lock pin is properly inserted within the
regulated release mechanism.
NOTICE
Failure to follow these instructions may lead
to system actuation.
2. Verify that cartridge has been removed from regulated
release assembly and that the regulated release mecha-
nism is in the cocked position.

WARNING
To reduce the risk of explosion due to leaking gas, make
certain that the gas line is turned off before connecting
the gas valve. Failure to comply may result in serious
personal injury or death. Gas valve installation shall be
performed by qualified individuals in accordance with local
jurisdiction requirements.
Install each electric gas valve to its selected location in gas
line so that it ensures safe shut-off to all predetermined
appliances being protected upon actuation of the system.
Refer to manufacturer’s instructions (if provided). See
Figure 5-112.
a. Use new pipe properly reamed and clean of metal chips.
b. Install valve so that the actuator is above the horizontal
pipe line with no more than a five degree (5°) lean either
way.
c. Make certain gas flow is in the same direction as arrow
shown on gas valve.
d. If strainer is utilized, attach strainer ahead of gas valve.
e. If necessary, install drip leg in gas line in accordance
with authority having jurisdiction.
4. Install and secure 1/2 in. conduit from each electric gas
valve to manual reset relay enclosure.
5. Tag and connect electrical wiring to each electric gas valve.
Then, feed wire through conduit to manual reset relay. Tape
or place a wire nut on any unused wire leads in accordance
with authority having jurisdiction. Refer to Figures 5-122 —
5-125 at the end of this section for typical wiring diagrams.
