OPERATION
WARMING OVEN:
The oven is heated by the flue products from the broiler. To operate the broiler burners just to heat the oven, when
the broiler is not in operation, is inefficient and not recommended. When the optional electric element is installed in
this oven, it can be used when the broiler is not operating, or to increase the temperature of this oven when the
broiler burners are operating. There is no thermostat to regulate this oven temperature. The only control is the ON
and OFF switch.
POWER FAILURE:
In the event of an electric power failure, no attempt should be made to operate those units with an "A" suffix. Turn
off all gas and the blower switch until power is restored. Units with a "D" suffix will operate during power failures.
OVEN: (Ovens on all models are identical)
1. Open door, raise hold-down clips, and remove oven bottom so burner is visible.
2. Turn oven burner to OFF.
3. Remove panel from spring compartment below oven door.
4. Depress RED button on safety valve and light pilot. New installations may require time to bleed air from
system before pilot will become steady. The pilot flame should impinge on the bulb to cause it to glow red. If
flame is too long and soft, bulb may be in "hollow" part of flame and will not glow.
5. Hold RED button, allowing pilot to burn approximately 45 seconds, until tip of bulb glows red and then release
button.
If pilot does not remain ignited, wait 5 minutes and repeat procedure.
6. Once pilot holds when button is released, set thermostat dial to maximum and turn ON the oven valve at
manifold.
7. Burner flames should be 3/4" to 1" long. Adjust if necessary.
8. Reduce thermostat setting slowly until bypass seat in thermostat just snaps OFF.
Immediately reverse rotation and turn dial counterclockwise until bypass snaps open.
The bypass flame should be 1/8" minimum and 1/4" maximum on each port.
A small fluttering bypass flame may flash back into the burner and ignite on the orifice when the door is
quickly opened or closed. This will create a c arbon deposit inside the burners which impedes proper primary air
injection. See section on bypass flame adjustment.
9. Check entire oven gas system for leaks.
10. Replace oven bottom and be sure hold-down clips are lowered to keep bottom in place and prevent warping.
OVEN SHUT DOWN:
Daily:
Turn main oven gas valve to "OFF" position.
Complete Shut Down:
Turn main oven gas valve to "OFF" position and extinguish oven pilot.
