INSTALLATION
when pressure testing of that system at pressures in excess of
1/2 psi (3.45 kPa).
Check the data plate to determine the proper type of gas
before connecting the quick disconnect or piping from the
building gas supply.
An incoming gas pressure test nipple is provided on the
incoming gas manifold for pressure checks.
Minimum incoming gas pressure for Natural Gas is 6" W.C.
Maximum incoming gas pressure for Natural Gas is 13" W.C.
Minimum incoming gas pressure for Propane is 10" W.C.
Maximum incoming gas pressure for Propane is 13" W.C.
Burner operating gas pressure can be checked at the outlet
side of the gas valve at the pressure test point.
Burner manifold pressure for Natural Gas must be 3.2" W.C.;
Burner pressure for Propane must be 3.5" W.C.
To adjust the burner pressure, remove the sealing screw
from the pressure test nipple, connect a manometer, remove
the sealing cap on the gas valve regulator, turn on the grill,
adjust the screw in the regulator to give the correct pressure,
turn o the grill, re t the regulator sealing cap, remove the
manometer, replace the seal screw in the test nipple and test
for gas leaks.
Gas pressures should be checked by the local Gas Company
or an authorized service agency only.
Test all piping and connections for gas leaks. A rich soap
solution should be used for this purpose. Never use a ame.
Accessory Kit – Main Gas Inlet:
(Accessory kit part numbers 4524785 or 4525509 and also
includes electrical supply lines, see next section).
Each griddle is supplied with an extended rear gas manifold
kit., with the following parts.

failure of the upper microswitch.
Installation shall be made with the gas connector that has
been supplied loose with the grill. The quick disconnect
tting and gas shut o valve must be installed in the
direction indicated on their outer body.
NOTE: When checking gas pressure, be sure that all other
equipment on the same gas line is on.
The appliance and its individual shut-o valve must be
disconnected from the gas supply piping system during any
pressure testing of that system pressures in excess of ½ PSIG
(3.45kPa, 14” WC).
Adequate clearance must be provided for servicing and
proper operation.
National Codes Requirements:
The type of gas for which the grill is equipped is stamped on
the data plate on the inside rear of the unit and on the lower
front panel. Connect a grill stamped for Natural Gas only to
Natural Gas.
The installation must conform to the National Fuel Gas Code
ANSI Z223.1-1998 or latest edition, NFPA No. 54 – latest
edition and National Electrical Code ANSI/NFPA 70-1990 or
latest edition and/or local code to assure safe and e cient
operation. In Canada, the installation must comply with CSA
B149.1 and local codes where applicable
In Canada, electrical connection must comply with
applicable sections of the Canadian Electrical Code, C22.1
- 1990, latest edition, “Safety Standard for Installation,
Part 1” and C22.2- No. O-M 1982 latest edition , “General
Requirements, Part 2”.
Gas Connections, and Pipe Sizing:
The size of the gas line is very important. If the line is too
small, the gas pressure at the burner manifold will be low.
This will cause slow recovery and delayed ignition. The
incoming gas pressure line should be a minimum of 1-1/2".
All grills require a 3/4" connection.
Before connecting new pipe the pipe must be blown out to
dispose of any foreign particles. These particles will cause
improper operation.
When using thread compound, use small amounts on male
threads only. Use a compound that is not a ected by the
chemical action of LP gases. Avoid applying compound
to the rst two threads to prevent clogging of the burner
ori ces and control valve.
Have the installer check all gas plumbing with a soap
solution for leaks. DO NOT USE matches, candles or other
ignition sources in checking for leaks.
The grill must be disconnected from the gas supply system
