INSTALLATION MUST BE MADE BY A LICENSED/QUALIFIED COMMERCIAL GAS EQUIPMENT
SERVICE AGENCY/COMPANY
The input rating on your appliance is for elevations up to 2,000 feet. For elevations above 2,000 feet the rating must
be reduced to 4% for each 1,000 feet above sea level.
INSTALLATION, OPERATION & MAINTENANCE
(1)
PRE-INSTALLATION - SPACE AND GAS CONNECTIONS
(a)
The area around the appliance must be kept free and clear from combustibles. The area in front of
and above the appliance must be clear to avoid any obstruction to the flow of combustion and ventilation air. Means
must be provided for adequate air supply and adequate clearance from air openings into the combustion chamber.
(b)
Adequate clearance must be provided in front and sides of appliance for servicing and proper
operation.
(c)
Your appliance is designed for installation in a combustible or non-combustible location. If the
appliance is installed in a combustible location, the following clearances must be observed: 6" to sides and 8" to back.
If installed in a non-combustible location, the clearances are: 0" sides and 0" back.
(2)
INSTALLATION
(a)
The gas pressure regulator supplied with the appliance must be installed on the appliance prior to
connection to the gas supply lines. The outlet pressure setting is 5" water column on natural gas and 10" water column
on propane gas (LP Gas). THE NORMAL FLAME IS A 1/4" HIGH BLUE FLAME. OVERGASING THE
APPLIANCE WILL VOID THE WARRANTY.
(b)
Connect the appliance to a gas supply line having a 3/4" iron pipe size or larger. If a flexible
connector is used it must be 3/4" I.D. (Domestic range connector will not permit proper operation). A gas shutoff
valve must be installed in the gas supply line ahead of the appliance for future service. Use pipe sealant on all joints.
Sealant must be resistant to the action of LP gas. A 1/8" pressure tap is provided on the gas manifold for checking the
gas pressure. Always check pressure with all burners on and adjacent equipment operating.
(c)
Level the appliance by adjusting feet at the bottom of the legs. Leveling is important for proper
operation and combustion. If a level is not available, use pan of water.
(d)
To check for leaks, use a soap and water solution. DO NOT USE OPEN FLAME.
(e)
The appliance and its individual shutoff valve must be disconnected from the gas supply piping
system during any pressure testing of the system at test pressures in excess of 1/2 psig (3.45kPa).
(f)
The appliance must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the system at test pressure equal to or less than 1/2 psig (3.45kPa).
(3)
OPERATION
(A)
LIGHTING THE BROILER
(1)
Turn off all burners and pilot valves. Wait 5 minutes.
(2)
Turn on burner valves and light all pilots. Remove the drip pan for access to the pilots or
remove the top grates.
(3)
Adjust pilot flame by turning the pilot valve screw clockwise or counterclockwise.
(B)
PREPARATION FOR COOKING
(1)
Before cooking, clean grates with a detergent and immediately preheat broiler for 30
minutes with burners on full. Rub grates with cooking oil or suet.
(2)
Broilers are provided with grates that have two (2) cooking positions. Use grates in the
lower position for broiling foods that have low fat content and when cleaning grates.
(3)
For normal broiling, grates should be raised at the rear to the elevated position so that
excess fat will run forward and drip into the grease trough.
