INSTALLATION & SERVICE CONNECTIONS
SECTION 1: MODELS: GC-2 & GC-3
START UP TEST RUN
Open manual gas shut off supply valve and if the appliance has a manual Blow Down Valve, close
it. Open left cabinet door and turn ON power switch. Pilot light will come on (green) and water will
begin to enter Boiler and required water level will be reached in about 3 minutes. Observe water
gauge glass to verify.
The Dial on the gas combination control valve has 3 positions (ON-PILOT-OFF) for manual gas
control of main burners and pilot. Turn Dial on gas combination valve to PILOT. Depress Dial and
light Pilot Burner located on centre main burner of Boiler. Maintain Dial in depressed position for
about 30 seconds and release. Observe that Pilot Burner flame stays on. If at any time the flame
should become extinguished, a 5 minute period for complete shut off of Gas Supply is required
before relighting.
Turn Dial to ON and burners will ignite. Steam generation will now commence and be completed in
about 15 minutes. Observe that Boiler Pressure Gauge indicates steam pressure in range of 9 - 12
psi. The Pressure Gauge on the face of the Cooker Control Panel should indicate pressure of 5 to 6
psi.
Open Cooker compartment door. Dial Timer to 5 minutes and pull out Operating Handle and
observe that steam enters compartment.
With Operating Handle pulled out, dial Timer back to "O". The buzzer will now be audible and must
be silenced by releasing Operating handle. Check each compartment in a similar manner.
Close compartment door and turn Handwheel clockwise sufficiently to provide a good seal on door
gasket. Dial Timer to 5 minutes. Pull out Operating Handle and set in position. Steam entry into
compartment will be audible and Compartment Vent, located at rear left side of Cooker
compartment, will exhaust air (hissing noise) trapped in the compartment until replaced by steam.
Observe that door gasket seals properly and no leaks are evident.
After 5 minutes the Timer will read "0", Buzzer will come on, steam will cease to enter
compartment and drain valve will open to exhaust steam and condensate from compartment.
Release Operating Handle to silence Buzzer.
Observe Appliance Drain that live steam
from
compartment is being cooled by cold water from Cold
Water Solenoid Valve (thermostatically controlled). Turn Handwheel fully counter-clockwise to
avoid pressure on door gasket when not in use. Check each compartment in a similar manner.
During simulation of the cooking cycle, the Burners will cycle on and off to maintain steam
pressure in Boiler between 9 to 12 psi range.
Turn OFF power switch. Observe that Burners go off and if the appliance is equipped with
Automatic Blow Down Solenoid Valve, the Boiler contents water and steam, will be blown out and
exhausted through the appliance Drain. The Cold Water Solenoid Valve will now be activated as
well. If the appliance is equipped with a manual Blow Down Valve, open it.
