MKG SERIES GAS GRIDDLE INSTALLATION & OPERATION

1.6.
FINAL GAS CONNECTION:
A properly installed gas supply system will deliver adequate pressure (7 to 8 inches w.c. for natural gas, 11 to 12 inches
w.c. for propane) to all appliances connected to the line, operating at full demand.
1.6.1.
Regulator Assembly:
An adequate gas supply is important for the appliance to operate properly. Undersized lines or low-pressures will restrict the
volume of gas required for satisfactory performance. A steady supply pressure between 7” and 8” w.c. for natural gas or 11” to
12” for propane gas is required. With all gas appliances operating simultaneously, the manifold pressure on all gas appliances
should not show any appreciable drop. Fluctuations of more than 25% on natural and 10% on propane gas will create pilot
problems and affect burner operating characteristics. Contact your gas company for correct supply line sizes. After connection,
a certified gas service agent should check all newly installed equipment for correct gas pressure. The unit should be connected
ONLY to the type of gas for which it is equipped. Check the type of gas on the serial plate.
FIGURE #2
A.
Attach regulator supplied with the appliance to the gas inlet supply pipe located at the rear of the unit.
Appliances equipped with Matchless Ignition controls are also supplied with a ¾” manual shut off valve. Be
sure regulator is connected so that gas flow is in the direction of the arrow on the bottom of the regulator. See
figure #2 for the correct installation of the regulator piping components. Using a regulator other than the one
supplied with the unit will void the warranty.
B.
The manifold pressure must be maintained at the pressure marked on the Data plate. For appliances equipped
with Solid State or Electric Thermostat controls the pressure reading is taken at the pressure tap supplied on
the ¾” manual shut off valve, see figure #2. For all other griddles, a pressure tap is located behind the door
on the 1.0" square manifold, see figure #3.
C.
Use pipe joint compound that is suitable for use with LP gas on all threaded connections.
D.
Turn off all thermostats.
E.
Turn on gas supply and check all connections for leaks using ONLY a leak checking fluid or soapy water.
NEVER use an open flame to check for gas leaks.
F.
Provision must be made for adequate air supply for both the appliance and room occupants.
G.
Keep area in front of unit free from obstruction that could block flow of combustion and/or ventilation air.
H.
Be certain that adequate clearance is maintained so that air openings in front of the unit are not blocked and
any subsequent service can be performed. Ensure that rear and side clearances stated on the serial plate and in
the clearance section of this manual are strictly followed.
