switch in the “AUTO” position.
TITAN-CONVECTION OVEN – ELECRIC IGNITION OVEN
TO LIGHT CONVECTION OVEN:

P/N 24-132 REV A 7/00 Page 6
With gas connections and necessary piping correctly installed to and at the appliance according
to the latest National Fuel Code and with the wiring correctly installed to the latest electrical
codes – proceed as follows:
1. Turn on main electrical power to the appliance (circuit breakers).
2. With main gas valve to appliance turned on immediately light all freestanding top burners
pilots. Adjust flame if necessary.
3. Turn appliance electrical “ON-OFF” toggle switch to “ON” position. (Power “ON” light –
Amber color – will come on.)
4. Turn electric thermostat to desired temperature. (This will allow the oven burner lighter
circuit to commence functioning.) GREEN light will come on. Within a few seconds oven
burner will ignite and oven is ready for use.
5. Turn on oven Blower toggle switch to “AUTO.” This turns on oven fan.
6. With oven fan in operation, pre-heat oven. It usually takes 12 to16 minutes.
7. When ready, open oven door. Fan will stop automatically.
8. Quickly place product into oven.
9. Close oven door. Fan will re-commence operating and product will start to be processed.
GENERAL INFORMATION
If it if necessary to lower oven temperature very rapidly to accommodate a different product,
simply adjust thermostat to the lowest selected temperature. Open oven door and place rocker
switch to manual. This will allow blower to operate and disperse excess heart rapidly from oven
cavity (usually seconds). When ready, place new product in oven, close door and place blower
switch in the AUTO position. With the blower switch in this position the fan will operate only with
the door closed. Opening the door will stop blower preventing hot air from blowing in the Chef’s
face.
To turn blower off place rocker switch in “OFF” position.
When the oven is no longer needed turn, off the blower switch and thermostat.
It is sometimes advisable to turn off blower to allow certain products to set, e.g. milk products,
meringues, etc. The blower should not be disengaged for more than 2 to 3 minutes at a time.
The use of the convection oven without running the blower does not cause damage to the
appliance, but it reduces the efficiency of the oven, cooking time and heat distribution.
Therefore, we recommend that the blower be used constantly whenever the oven is in
operation.

The Jade Convection Oven described within these instruction sheets under the “Titan
Convection Oven-Gas Controls” can also be equipped with electric ignition.
SERVICE AND MAINTENANCE
Contact the factory, factory representative or a local service company to perform maintenance
and repairs.
For daily cleaning, turn “ON” burner valves on top sections for 2 to 3 minutes and then turn
“OFF.” Use warm water and mild cleanser on fry top plates and open top grates. On hot top
plates, use a rough cloth to clean plates. DO NOT use water to clean hot top plates.
Once a month, clean all burners with water and steel brush ensuring that all burner ports are
free of debris. Clean pilots in same manner. Once cleaned and dried, re-light pilots and check
for blockage. As frequently as necessary, remove grease tray, empty and clean with mild
detergent.
