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 in a 24" cabinet base rated at 140,000 or 200,000 BTU, 36" cabinet base rated at 200,000, 250,000 or 300,000 BTU, operational on Natural or Propane gas. Boilers may have optional electronic ignition and CSD1 controls.

1.0 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 of 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 CABINET

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

The boiler must be installed in accordance with:

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 accordance with CSA B149.1 Natural Gas and Propane Installation Code.

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.

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 receptacle. Do not cut or remove the grounding prong from this plug. (120V units only).

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 inches 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 an appliance, check with the exhaust fan in the “OFF” position.
