These models are design-certified for operation on natural or propane gases. For natural gas, the
regulator is set to deliver a 3.5" W.C. pressure to the manifold. For propane gas, it is set to deliver
11" W.C.
This appliance should be connected ONLY to the type of gas for which it is equipped. The inlet
pressure before the regulator should be 6-10" W.C. for natural gas or 11-14" W.C. for LP gas.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of
gas required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10%
on propane gas will create problems and affect burner operating characteristics.
An adequate gas supply line to the unit should be no smaller than the I.D. of the pipe from the unit
to which it is connected.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to
the unit.
ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS. USE ONLY
SOAPY WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK FOR GAS
LEAKS. ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE UNIT HAS BEEN PUT INTO
OPERATION. TEST PRESSURE SHOULD NOT EXCEED 1/4" W.C.
Step 6: Check the Installation
1. Check that all screws and bolts are tightened.
2. Move the oven into the position at which it will be operated.
3. Check that the oven is level. If not, adjust the legs.
4. Check that the appropriate clearances are satisfied (see page 7)
