GAS-FIRED WATER BOILER SERIES 2 — User’s Information Manual
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.
Maintenance procedures
Daily
Verify boiler front
door is securely in
place
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.
Check air openings
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.
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.
Check boiler area
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.
