INSTALLATION (continued)
GAS PIPE PRESSURE TESTING
The main piping system must be capable of supplying the griddle with
sufficient volume/flow of fuel to satisfy the maximum operational input
requirements.
Make sure the supply piping system has been pressure tested before
the regulator and griddle are connected. If the system must be
re-tested, be sure the regulator is isolated by a manual shut-off valve,
in order to prevent damage to the regulator and gas griddle valves.
Piping and connections should be leak tested using a water/soap
solution. DO NOT USE FLAME TO CHECK FOR GAS LEAKS.
Equipment gas pressure (the pressure downstream of the pressure
regulator) may be tested by adapting a water column gauge to the
plugged ports on the main gas manifold. The pressure regulator
supplied with the Gas Griddle is factory set for a nominal gas pressure
of 5” w.c.
Be sure to remove any adapters, and to re-plug and leak check the
port before returning the griddle to service. Leak testing should be
performed using a water/soap solution. DO NOT USE FLAME TO
CHECK FOR GAS LEAKS.
GAS SUPPLY FLOW VOLUME TESTING REQUIREMENTS
While testing for adequate gas pressure, be sure all other gas
appliances that utilize the same source piping are in operation with
burners ON in order to ensure accurate operational conditions.
If flow volume in the system piping is marginal, and should other
appliances on that system not be consuming gas while testing for
pressure, the test results may be inaccurate.
IMPORTANT:
PRESSURE TESTING MUST
BE PERFORMED BY A
QUALIFIED TECHNICIAN
ONLY.
NOTE: The maximum inlet
pressure from the supply
piping must not exceed ½ p.s.i
(14” W.C.) Pressure above this
limit will damage the regulator
and gas valves.
Port for measuring outlet gas
pressure is located on the
manifold. Remove the grease
drawer to gain access.
Remove the allen head plug
sealing the test port, then
connect the hose of a water
column gauge.
Be sure to reinstall the allen
head plug at the conclusion of
testing.
