INSTALLATION
Gas and Electrical Information
INSTALLATION CODES AND STANDARDS
Installation must conform with local codes, or in the ab-
sence 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 pres-
sures in excess of 1/2 PSI (0.03 kg/cm2) (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
1/2 PSI (0.03 kg/cm2) (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.
Ventilation must be provided in accordance with local
codes, or in the absence of local codes, with ANSI/NFPA
96 Standard for Ventilation and Fire Protection of Com-
mercial Cooking Operations.
WARNING
ELECTRICAL GROUNDING INSTRUCTIONS
This appliance is equipped with a three-prong
(grounding) plug for your protection against
shock hazard and should be plugged directly
into a properly grounded three-prong recepta-
cle. Do not cut or remove the grounding prong
from this plug. (120V units only).
The electrical wiring diagram is located inside the right
hand console of the appliance.
GAS CONNECTION
WARNING
Do not connect the appliance to the electrical
supply until after the gas connection has been
made.
CAUTION
The pipe thread compound used when install-
ing pipes must be a type that is resistant to
the action of liquefied petroleum or propane
gases.
1. The Serial and Rating Plate on the unit indicates the
type of gas your unit is equipped to burn. DO NOT
connect to any other gas type.
2.
A 3/4” NPT line is provided at rear for the connec
-
tion. The unit is equipped with an internal pressure
regulator which is set at 4” W.C. manifold pressure for
Natural Gas and 10” W.C. for Propane Gas. Use 1/8”
pipe tap on the union elbow assembly located in the
console 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 supply pressure, mini-
mum 6 inch W.C. for natural gas and minimum 12 inch
W.C. for propane gas is recommended. With all units op-
erating 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 problems, affecting burner op-
eration. Contact you 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.
Use pipe joint compound which is suitable for use with
L.P. on all threaded connections.
Test pipe connections thoroughly for gas leaks.
WARNING
Never use an open flame to check for gas
leaks. Check all connections for leaks using
soapy water before use.
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.
