The following terms are used throughout this manual to bring attention to the presence of hazards of various risk levels.

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death, serious injury or substantial property damage.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, may result in moderate or minor injury or property damage.

WARNING

Important Product Safety Information: Refractory Ceramic Fiber Product.

• Some boiler components such as combustion chamber insulation use materials that contain refractory ceramic fibres (RCF). RCF has been classified as a possible human carcinogen. When exposed to elevated temperatures, RCF may change into crystalline silica, a known carcinogen. When disturbed as a result of servicing or repair, these substances become airborne and, if inhaled, may be hazardous to your health.
• Do not handle RCF parts or attempt any service or repair work involving RCF.
• Service agencies must use precautionary measures as stated in the boiler Installation, Operation, and Service manual.

Basic Operation

CAUTION

• Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a location external to the appliance.
• Do not use this boiler if any part has been underwater. Immediately call a qualified service technician to inspect the boiler and to replace any part of the control system and any gas control that has been under water.

General This boiler is equipped with controls for proper operation. All controls must be in proper working order. Contact a qualified service agency to provide annual maintenance as specified in the Installation, Operating and Service Instructions.

WARNING

Service on this boiler should be undertaken only by trained and skilled personnel from a qualified service agency.

1. Limit See Figure 1. A device that automatically interrupts boiler operation when the water temperature exceeds the set point. Maximum allowable boiler water temperature is 220°F. The maximum switch differential is 30°F.

2. Blocked Vent Switch See Figure 1. A device that automatically interrupts boiler operation when excessive vent system blockage occurs. If the control was activated to interrupt boiler operation, do not attempt to place boiler in operation. Contact a qualified service agency.
   WARNING
   Do not reset the Block Vent Switch unless a qualified service agency has determined and corrected the cause of any blockage in the vent system or chimney.

3. Flame Rollout Switch See Figure 1. A device that automatically interrupts boiler operation when flames or excessive heat are present in the vestibule. The control is a single use device. If the control was activated to interrupt boiler operation, do not attempt to place the boiler in operation. Contact a qualified service agency.

4. 24-Volt Intermittent Ignition System (EI). See Figure 1. The Electronic Ignition System consists of:

5. an ignition module to initiate, monitor and stop burner operation.

6. a combination gas valve to regulate gas flow to burners.

7. a pilot burner to provide the ignition source for the main burners.

Instructions to place the boiler in operation andto turn off the boiler are shown on the Operating Instruction label posted on the inside of the front removable door. See Figure 2 for front door removal instructions. Operating Instructions are also shown in F igure 3.

Maintenance

WARNING

• Service on this boiler should be undertaken only by trained and skilled personnel from a qualified service agency. Inspections should be performed at intervals specified in Installation, Operating and Service Instructions and this manual. Maintain manuals in a legible condition.
• Keep the boiler area clear and free of combustible materials, gasoline and other flammable vapors and liquids.
• Do not place any obstructions in the boiler room that will hinder the flow of combustion and ventilation air.

General Housekeeping (Continuous).

1. Keep boiler area clear and free of combustible materials and obstructions to the free flow of combustion and ventilation air to the boiler.
2. Do not store or use gasoline or other flammable vapors, liquids or other sources of hydrocarbons in the vicinity of the boiler or any other appliance.
3. Do not store or use halogen-containing products (bleaches, cleaners, chemicals, fabric softeners, refrigerants, etc.) in the vicinity of the boiler.

Inspect Vent System (Monthly). See Figure 4. Follow the instructions TO TURN OFF GAS TO APPLIANCE (see Figure 3) and contact a qualified service agency if any of the following conditions are found:

1. Collapsed vent pipe
2. Disconnected or loose joints
3. Sags in horizontal runs
4. Corrosion or other deterioration
5. Broken or loose supports
6. The blocked vent switch is not attached to the draft hood.

Inspect Pilot and Main Burner Flame (Monthly).

1. Adjust the thermostat to lowest setting.
2. Remove the front removable panel. See Figure 2.
3. Adjust the thermostat to the highest setting.
4. Check pilot burner flame through the observation port. See Figure 5 for the pilot burner illustration. The centre flame should be steady, medium hard blue enveloping 3/8 to 1/2 inch of a thermocouple. If flames are yellow and lazy, follow instructions TO TURN OFF GAS TO APPLIANCE (see Figure 3) and contact a qualified service agency.
5. Check the main burner flames through the observation port. See Figure 6. The flame should have clearly defined inner cones with no yellow tipping. Orange-yellow streaks caused by dust should not be confused with true yellow tipping. If yellow flames are observed, follow instructions TO TURN OFF GAS TO APPLIANCE (see Figure 3) and contact a qualified service agency.
6. Adjust the thermostat to its normal setting. D. Schedule Inspection by a Qualified Service Agency (annually or at the beginning of the Heating Season). For continued safe operation a qualified service agency must provide a more detailed inspection of burners, heat exchangers and vent system, and provide maintenance as specified in Installation, Operating and Service Instructions.
