NOTE: No additional clearance from the sides and back is required for service, as the units are

E2iHAUST FANSAND CANOPIES:

Canopies are set over ranges, ovens, etc., for ventilation purposes. It is recommended that a canopy extend 6” past appliance and be located 6’6” from the floor. Filters should be installed at an angle of 45 degrees or more with the horizontal. This position prevents dripping of grease and facilitates collecting the run-off grease in a drip pan, usually installed with a filter. A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot

flames. Fresh air openings approximately equal to the fan area will relieve such vacuum. In case of unsatisfactory perf

ST&EB;;~LmOm~D BY QUALIFIED

A I” NPT line is provided at the rear for the connection. Each unit is equipped with an internal pressure regulator which is set propane gas. Use 1/8” pipe tap on the burner manifold for checking pressure.

An adequate gas supply is imperative. Undersized or low pressure lines will restrict the vohrme of

gas requked for satisfactory perhonnauce. A steady supply pressure, 6” W.C. for natural gas aud 10” W.C. for propane gas, is recommended. With all uuits operating simultaneously, the manifold pressure on all units should not show any appreciable drop. natural gas, and 10% on propane gas, will create pilot problems and affect burner operating characteristics. Contact your gas company for correct supply line sizes.

Purge the supply line to clean out any dust, dirt, or other foreign matter before connecting the line to the unit. It is recommended that an individual manual shutoff valve be installed in the gas supply line to the unit. Use pipe joint compound which is suitable for use with LP gas on all threaded connections. Test pipe connectious thoroughly for gas leaks. USE SOAPY WATER ONLY FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

ALL CONNECTIONS MUST BE CHECKED FOR IEAKS, AFTER TIIE UNIT HAS BEEN PUT IN OPERATION.
