GENERAL
The gas boiler is designed to ASME Code and approved as a steam heating boiler
restricted to operation at pressure not to exceed 15 psi. The gas boiler may be
operational on Natural or Propane gas. Boilers have electronic ignition and may have
optional CSD1 controls.
2.0 INSTALLATION INSTRUCTIONS
UNPACKING
Immediately after unpacking, check for possible shipping damage. If the appliance is
found to be damaged, save the packaging material and contact the carrier within 15
days of delivery.
Before installing, verify that the gas (natural or propane), the elevation from sea level
and the electrical supply agree with the specification on the data plate. NOTE: If this
appliance is being installed above 2000 feet altitude, contact your authorized service
office to assure that the proper orifice size for your elevation has been installed.
LOCATION
The installation location must be kept free and clear of combustibles. Do not obstruct
the flow of combustion and ventilation air. Clearance from combustible construction
must be a minimum of 3 inches from the sides and 6 inches from the back. The
appliance should be installed on a noncombustible floor. Provide adequate clearances
for cleaning, maintenance, service and proper operation.
Sufficient air should be allowed to enter the room to compensate for the amount of air
removed by any ventilating system and for combustion for the gas burners. Do not
obstruct the air flow into and around the appliance. Do not obstruct the flow of flue
gases from the flue duct located at the rear and above the cabinet. Position the
appliance in its final location. Check that there are sufficient clearances to service the
controls, for door swings, etc., so there will be no problem in making the required supply
and drain connections.
Allow enough space between any other piece of equipment or a wall for service access.
Service on the cabinet base may require access to the left and/or right side panels.

LEVELING AND ANCHORING THE APPLIANCE
1. Place appliance in the installation position.
2. Place a carpenter’s level on top of the appliance and turn the adjustable feet to level
side-to-side and front-to-back.
3. Mark hole locations on the floor through the anchoring holes provided in the rear
flanged adjustable feet.
4. Remove appliance from installation position and drill holes in locations marked on
the floor. Insert proper anchoring devices (not supplied).
5. Place appliance back in the installation position.
6. Place carpenter’s level on top of appliance and re-level side-to-side and front-toback.
7. Bolt and anchor appliance securely to the floor.
8. Seal bolts and flanged feet with silastic or equivalent compound.
INSTALLATION CODES AND STANDARDS
Gas installation to conform to local codes, or in 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, including:
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 psig (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 psig (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. In Canada, installation
must be in accordance with the Canadian Electrical Code CSA C22.2.

WIRING DIAGRAM FOR APPLIANCE IS LOCATED INSIDE CABINET DOOR.
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 feet 6 inches
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 with the
exhaust fan in the “OFF” position.
SERVICE CONNECTIONS
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.
PLUMBING CONNECTIONS
WARNING: Plumbing connections must comply with applicable
sanitary, safety, and plumbing codes.
WATER SUPPLY CONNECTION
The incoming cold water supply connection, at the rear of the steamer cabinet, requires
3/8" tubing and water pressure of 25 - 50 psi. A manual shut-off valve must be provided
convenient to the appliance; this valve should be open when the boiler is in operation.
FAILURE OR MALFUNCTION OF THIS APPLIANCE DUE TO POOR WATER
QUALITY IS NOT COVERED UNDER WARRANTY. SEE WATER QUALITY
STATEMENT (PAGE 4)
DRAIN CONNECTION
The steamer drain (2" IPS) should be piped to a floor drain near the steamer. There
should be no solid drain connection; an “open gap” between the steamer and the floor
drain is required.
