PAGE 1-2 SERVICE MANUAL WG-xxG Series Gas Griddles Introduction
GAS PIPING REQUIREMENTS Cont
Supply piping should be a minimum of % inch
black iron pipe with a sediment trap (drip leg)
consisting of a pipe tee, 4" nipple with cap to
prevent dirt from entering the control valves
(Consult local codes and ordinances for
guidance for this requirement, or in the
absence of local codes, use the National Gas
Code ANSI Z223.1 and NFPA No. 54).
Pipe thread compounds should be of a type that
is resistant to the action of LP (Liquid Petroleum
Gases).
Do not use Teflon Tape or Teflon pipe Compound
on the inlet connections, use a good quality pipe
thread compound. Apply pipe dope sparingly to
the male threads only.
Be sure all gas piping is clean and free of
obstructions, dirt, and piping compounds. A
manual shut-off valve between the % inch feed
pipe and the system manifold should be installed
for safety when servicing the griddle.
GAS PIPING PRESSURE TESTING
Make sure the supply piping system has been
pressure tested before the regulator and griddle
is connected. If the system must be re-tested, be
sure the regulator is isolated by a manual shut-off
valve to prevent damage to the regulator and
griddle gas valves.
Always check piping joints for leaks with a soap
and water or other approved leak detection
solution after any pipe connections are disturbed
or changed.
The main system piping must be capable of
supplying Griddle with sufficient volume/flow of
fuel for maximum input (Operational)
requirements.
NOTE:
The maximum inlet pressure from the
supply piping should not exceed % P.S.I.
(14" W.C.). Pressures above this limit will
damage the regulator and gas valves hi
the unit.
GAS SUPPLY FLOW/VOLUME REQUIREMENT
When testing for adequate gas pressure, be sure all
other gas appliances that utilize the same source
piping are in operation with burners "ON" for an
accurate operational condition.
If other appliances are not consuming gas when
testing for pressure, the test may be inaccurate if flow
volume is marginal in the system supply piping.
LEVELING GRIDDLE
Make sure the griddle is level before connecting to the
gas supply piping.
Re-check the leveling after piping connections
are completed to avoid improper cooking on a
slanted surface.
