INSTALLATION
Installation
SETTING IN PLACE
The location of installation must be under an exhaust
hood, which will remove small amounts of water vapor
emitted when the cooker doors are opened, and exhaust
fumes. Level the unit in final location by turning the ad
-
justable feet. Using the cabinet top as a reference, obtain
level adjustment left-to-right and front-to-back.
MECHANICAL CONNECTIONS
Since the Pressureless Cooker is interconnected at the
factory to the steam boiler, no field connections to the
cooker are required. All electrical and plumbing connec
-
tions are located on the rear middle panel of the cabinet.
GENERAL
Gas installation to conform to local codes, or in absence
of local codes, with the National Fuel Gas Code - ANSI
Z223.1/NFPA 54. In Canada installation to be in accor-
dance with the Natural Gas and Propane Installation
Code, CSA B149.1. and or local codes.
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).
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 sup-
ply piping system at test pressures equal to or less
than 1/2 PSI (0.03 kg/cm2). 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. In Canada, installation must
be in accordance with the Canadian Electrical Code
CSA C22.2.
WARNING
Electrical grounding instructions - Units come
equipped with a three-prong (grounding) plug
for your protection against shock hazard and
should be plugged directly into a properly
grounded three-prong receptacle. Do not cut
or remove the grounding prong from this plug.
(120 VOLT UNITS ONLY).
EXHAUST FANS AND CANOPIES
Canopies are set over ranges, ovens, kettles, etc., for
ventilation purposes. It is recommended that a canopy
extend 6” past the 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 drip-
ping of grease and facilitates collecting the run-off grease
in a drip pan, usually installed with the filter. A strong ex
-
haust 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 unsatisfacto-
ry performance on any appliance, check with the exhaust
fan in the “OFF” position.
WALL EXHAUST FAN
The exhaust fan should be installed at least two 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 for use on noncombustible floors. Minimum
clearance from combustible and noncombustible con-
struction, 0” on left side, 0” on right side and 6” from back.
WARNING
These procedures must be followed by quali-
fied personnel or warranty will be voided. An
open gap floor drain is required immediately
below the appliance drain.
TO INSTALL
1. Uncrate carefully. Report any freight damage to the
freight company immediately.
2. Set the unit in place. Be certain to maintain the mini-
mum clearances from combustibles and non-com-
bustibles.
3. For an appliance supplied with legs, level the appli-
ance using a spirit level. Should flanged adjustable
feet be provided, anchor to floor using proper anchor
-
ing devices.
4.
Seal bolts and flanged feet with Silastic or other
equivalent compound.
5.
Be certain to leave adequate clearances for cleaning,
maintenance and service.
GAS CONNECTION
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. Each compartment is equipped with an internal
pressure regulator which is set at 3.5” W.C. manifold
pressure for natural gas and 10” W.C. for propane
gas. Use c” pipe tap on the burner manifold for check-
ing pressure.
