Asco Mechanical Gas Valves; Ansul Mechanical Gas Shut-Off Valves - Amerex 20150 Design, Installation, Maintenance & Recharge Manual

ASCO MECHANICAL GAS VALVES

All Amerex Kitchen Fire Suppression Systems that protect any gas
fired cooking appliance must use a "pull to close" type gas shut-off
valve, which is listed with the system. The valve is held open with a
latching device. Upon system discharge a piston in the gas trip
assembly (sold separately) will pull on a cable connected to the latch
on the gas valve, release the latch and allow the spring in the valve
to close the valve. The ASCO gas shut-off valves approved for use
with Amerex Kitchen Fire Suppression Systems are listed below with
appropriate part numbers. See "Installing a Mechanical Gas Valve"
in the Installation section for instruction on installation.
Note:
P/N 12740 Gas Trip Assembly must be purchased separately.

ANSUL MECHANICAL GAS SHUT-OFF VALVES

All Amerex Kitchen Fire Suppression Systems that protect
any gas fired cooking appliance must use a "pull to close"
type gas shut-off valve. The valve is held open with a
latching device. Upon system discharge a piston in the
gas trip assembly will pull on a cable connected to the
latch on the gas valve, release the latch and allow the
spring in the valve to close the valve. Ansul's mechanical
gas shut-off valves are suitable for use with Amerex
Kitchen Fire Suppression Fire Suppression system.
These valves, when used in conjunction with P/N 12740
Gas Trip Assembly, perform the same functions as
Amerex's gas shut-off valves. The part numbers of the
valves acceptable for this use are listed below. They are
intended to be installed using the same installation
instruction as Amerex's gas shut-off valves; see Installing
a Mechanical Gas Valve in the installation section for
instruction on installation.
NOTE:
P/N 12740 gas trip assembly must be purchased
separately.
