Maintenance procedures

Boiler must be serviced and maintained

The boiler must be inspected and started annually, at the beginning of the heating season, by a qualified service technician. In addition, the maintenance and care of the boiler designated on page 5 and explained on pages 6 through 9 must be performed to assure maximum boiler efficiency and reliability. Failure to service and maintain the boiler and system could result in equipment failure, causing possible severe personal injury, death or substantial property damage.

The following information provides detailed instructions for completing the maintenance items listed in the maintenance schedule, page 5. In addition to this maintenance, the boiler must be serviced and started up at the beginning of each heating season by a qualified service technician.

Daily

Check boiler area

Check air openings

Check pressure/ temperature gauge

Verify boiler front door is securely in place

To prevent potential of severe personal injury, death or substantial property damage, eliminate all materials discussed below from the boiler vicinity and the vicinity of boiler combustion air inlet. If contaminants are found:

Remove products immediately from the area. If they have been there for an extended period, call a qualified service technician to inspect the boiler for possible damage from acid corrosion.

If products cannot be removed, immediately call a qualified service technician to repipe vent and air piping and locate vent termination/air intake away from contaminated areas.

1.Combustible/flammable materials — Do not store combustible materials, gasoline or any other flammable vapors or liquids near the boiler. Remove immediately if found.

2.Air contaminants — Products containing chlorine or fluorine, if allowed to contaminate the boiler intake air, will cause acidic condensate in the boiler. This will cause significant damage to the boiler if allowed to continue. Read the list of potential materials listed on page 4 of this manual. If any of these products are in the room from which the boiler takes its combustion air, they must be removed immediately or the boiler combustion air (and vent termination) must be relocated to another area. See WARNING above.

1.Verify that combustion and ventilation air openings to the boiler room and/or building are open and unobstructed.

2.Verify that boiler vent discharge and air intake are clean and free of obstructions. Remove any debris on the air intake or flue exhaust openings. If removing the debris does not allow the boiler to operate correctly afterwards, contact your qualifed service technician to inspect the boiler and vent/air systems.

1.Make sure the pressure reading on the boiler pressure/temperature gauge does not exceed 24 psig. Higher pressure may indicate a problem with the expansion tank.

2.Contact a qualified service technician if problem persists.

1.Visually inspect boiler front door to be sure it is sealed all around its perimeter. Verify that the two lower thumb screws are tight.

Replace boiler jacket front door after servicing. The boiler front door must be securely fastened to the boiler to prevent boiler from drawing air from inside the boiler room. This is particularly important if the boiler is located in the same room as other appliances. Failure to keep the door securely fastened could result in severe personal injury or death.
