2.0 INSTALLATION
INSTALLATION CODES AND STANDARDS
Installation must conform with local codes, or in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code,
CSA B149.1, as applicable.
1. The appliance and its individual shut off valve must be disconnected from the gas supply
piping system during any pressure testing of that system at pressures in excess of ½ psi
(3.5 kPa).
2. The appliance must be isolated from the gas supply piping system by closing its individual
manual shut off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psi (3.5 kPa).
Electrical grounding must be provided in accordance with local codes, or in the absence of local
codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA
C22.2, as applicable.
The electrical diagram is located on the inside of the console control cover.
EXHAUST FANS AND CANOPIES: Canopies are set over ranges, ovens and kettles for
ventilation purposes. It is recommended that a canopy extend 6" past appliance and be located
7.5 feet 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 the filter. A strong exhaust fan tends to create a vacuum in
the room and may interfere with burner performance or may extinguish pilot flames. Makeup
air openings approximately equal to the fan area will relieve such vacuum. In case of
unsatisfactory performance on any appliance, check operation with exhaust fan in the “OFF”
position.
WALL EXHAUST FAN: The exhaust fan should be installed at least 2 feet above the vent
opening at the top of the unit.
CLEARANCES: Adequate clearance must be provided in aisle and at the side and back.
Adequate clearances for air openings into the combustion chamber must be provided, as well
as for serviceability.
SIDES - 6 INCHES
BACK - 2 INCHES AT FLUE BOX
FLOORS - 6 INCH LEGS
All units must be installed in such a manner that the flow of combustion and ventilation air are
not obstructed. Provisions for an adequate air supply must also be provided. Do not obstruct
the lower front or right side of the unit, as combustion air enters through these areas. The
bottom of the control area must also remain unobstructed.

2.0 INSTALLATION (Continued)
TO INSTALL
1. Uncrate carefully. Report any hidden freight damage to the freight company immediately.
2. Set the unit in place. Be certain to maintain minimum clearances as stated above.
3. To level the unit use a spirit level in all directions on the top of the kettle (lid up).
1. Units with legs - adjust the bottom foot on each leg to overcome an uneven floor.
2. Units with casters - loosen the locking nuts, turn casters in or out as required and
tighten locking nuts.
4. Be certain to leave adequate clearances for cleaning, maintenance and service.
5. The pressure relief valve is located at the left rear of the unit. This area should be kept
clear and should not be in an area where operators will normally stand. The elbow on the
relief valve should be turned toward the floor. A maximum 3 foot, 3/4" diameter pipe may
be used to extend to the floor, but must not be piped directly to a drain. It must vent to the
atmosphere.
6. Check the pressure gauge on the front panel before operating. If the pressure gauge does
not indicate green vacuum zone (below 0 psi), see “Re-establishing Vacuum” section under
SERVICE, after completing installation instructions.
GAS CONNECTION
The serial plate on the lower right side of the unit indicates the type of gas your unit is equipped
to burn. Do NOT connect to any other gas type.
A 1" NPT line is provided at the rear for the connection. Each unit is equipped with an internal
pressure regulator which is set for 4" W.C. manifold pressure for natural gas and 10" W.C. for
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 volume
of gas required for satisfactory performance. A steady pressure, minimum 6" W.C. for natural
gas and minimum 11" W.C. for propane gas, is recommended. With all units operating
simultaneously, the manifold pressure on all units should not show any appreciable drop.
Fluctuations of more than 25% on 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.

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30
2.0 INSTALLATION (Continued)
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 shut off 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 connections thoroughly for gas leaks.
WARNING: All connections must be checked for leaks, after the unit
has been put in operation. Use soapy water only for testing on all
gases. Never use an open flame to check for gas leaks.
NOTICE: If this equipment is being installed at over 2,000 feet altitude and was
not so specified on order, contact service department. Failure to install with
proper orifice sizing may void the warranty.
WATER CONNECTION
On units equipped with an optional water fill valve connect a water line (minimum 1/4") to the
valve with a 1/4" NPT female fitting. Units with dual (hot and cold) valves must have the hot
water line connected to side with the hot water valve (red) and cold water line to the cold water
valve (blue). Plastic or rubber hose is not recommended, as it may melt against the hot kettle
side.
