GAS PRESSURE REGULATOR INSTALLATION
Gas regulator pressure is preset at 5" Water Column (W.C.) for natural gas, and 10" W.C.
for propane gas. No further adjustment should be required.
Make sure that the arrow on the underside of the regulator is oriented in the direction of
gas flow to the griddle (Fig. 4) and the regulator is positioned with the vent plug and
adjustment screw upright (Fig. 5).
Fig. 4 Fig. 5
The supply pressure (upstream of the regulator) should be 7 -9" W.C. for natural gas and
11-12" W.C. for propane gas. At no time should the griddle be connected to s upply
pressure greater than ½ psig (3.45 kPa) or 14" W.C.
TESTING THE GAS SUPPLY SYSTEM
When the gas supply pressure exceeds ½ psig (3.45 kPa), the griddle and its individual
shutoff valve must be disconnected from the gas supply piping system.
When the gas supply pressure is ½ psig (3.45 kPa) or less, the griddle should be isolated
from the gas supply system by closing its individual manual shutoff valve.
GRIDDLES MOUNTED ON STANDS WITH CASTERS
Griddles mounted on stands with
casters must use a flexible connector (not
supplied) that complies with the Standard for
Connectors for Movable Gas Appliances ANSI
Z21.69•CSA6.16, and a quick-disconnect device that
complies with Gas Fuel, ANSI Z21.3•CSA6.9. In
addition, adequate means must be provided to limit
movement of the appliance without depending on
the connector and the quick-disconnect device (or
its associated piping) to limit appliance movement.

Attach the restraining device at the rear of the
griddle as shown in Fig. 6.
If disconnection of the restraint is necessary, turn off the gas
supply before disconnecting. Reconnect the restraint prior to turning the gas
supply on and returning the griddle to its installation position .
Casters are only supplied on a griddle stand. If the griddle is mov ed for any reason the
griddle should be re-leveled (see LEVELING in this manual).
