GAS CONNECTION
All gas supply connections and any pipe joint compound must
be resistant to the action of propane gas. Codes require that
a gas shutoff valve be installed in the gas line ahead of the
rotisserie oven; use the valve provided. A gas pressure
regulator is supplied with the rotisserie oven.
Connect the rotisserie oven to a 1" (
2.5 cm) gas supply line
(Fig. 9). Make sure the pipes are clean and free of obstructions,
dirt and piping compound. Connecting the rotisserie oven to
a smaller gas supply line is not recommended because this
will reduce the effectiveness of the burners or cause improper
operation.
WARNING: PRIOR TO STARTING, CHECK ALL JOINTS IN
THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND
WATER SOLUTION. DO NOT USE AN OPEN FLAME.
For natural gas, adjust the gas pressure regulator to provide a manifold pressure of 5.5" W.C. (
1.37 kPa).
The minimum supply pressure for natural gas is 7" W.C. (
1.74 kPa); maximum is 14" W.C. (3.49 kPa).
For propane, adjust the gas pressure regulator to provide a manifold pressure of 11" W.C. (
2.74kPa).
The minimum supply pressure for propane is 12" W.C. (
2.98kPa); the maximum is 14" W.C. (3.49kPa).
The rotisserie oven and its individual shutoff valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of
1
/2 psi (3.45 kPa).
The rotisserie oven must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or
less than
1
/2 psi (3.45 kPa).
BEFORE FIRST USE
WARNING: DISCONNECT ELECTRICAL POWER BEFORE CLEANING.
Clean and sanitize the rotisserie oven inside and outside with warm, soapy water. Rinse thoroughly
and wipe dry with a soft, clean cloth. Clean all spits and accessories with warm, soapy water; rinse
thoroughly and wipe dry.
Care must be taken to ensure the burners and ignitors do not get wet. Refer to Cleaning, pages 18
through 20.
Before using the rotisserie oven for the first time, it must be "burned in" to release any odors that might
result from heating the new surfaces in the rotisserie oven. Remove all vinyl paper and operate the
rotisserie oven empty at the maximum temperature for 1 hour. Smoke with an unpleasant odor normally
will be given off during this burn-in period.

ELECTRICAL CONNECTION
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE
APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL
ELECTRICAL CODES.
WARNING: THIS MACHINE IS PROVIDED WITH A THREE-PRONG GROUNDING PLUG. THE
OUTLET TO WHICH THIS PLUG IS CONNECTED MUST BE PROPERLY GROUNDED. IF THE
RECEPTACLE IS NOT THE PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN.
Do not plug in until after the gas connection has been made and checked for leaks.
