110/155 User's information Manual
The boiler should be inspected and started annually, at the beginning of the heating
season, only by a qualifi ed service technician. In addition, the maintenance and care
of the boiler designated on page 5 and explained on the following pages must be
performed to assure maximum boiler effi ciency 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 mainte-
nance 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 qualifi ed service technician.
Check boiler area
To prevent potential of severe per-
sonal injury, death or substantial
property damage, eliminate all
materials discussed below from
the boiler vicinity. If contami-
nants are found:
Remove products immediately
from the area. If they have been
there for an extended period, call
a qualifi ed service technician to
inspect the boiler and vent system
for possible damage from acid
corrosion.
If products cannot be removed,
immediately call a qualifi ed ser-
vice technician to address the
problem.
1. Combustible/fl ammable materials — Do
not store combustible materials, gasoline or
any other fl ammable vapors or liquids near
the boiler. Remove immediately if found.
2. Air contaminants — Products containing
chlorine or fluorine, if allowed to con-
taminate the boiler intake air, will cause
acidic condensate in the vent and boiler.
This will cause signifi cant damage to the
vent and/or boiler if allowed to continue.
3. 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 com-
bustion air must be supplied from outside.
4. See WARNING above.
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 fl ue
exhaust openings.
Check boiler pressure/
temperature gauge
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 qualifi ed service technician if
problem persists.
Verify that boiler jacket
door is securely closed
1. Visually inspect boiler jacket door to be
sure it is sealed all around its perimeter.
Verify that the door latches are secure and
the retention screw is tight.
The boiler jacket door must be
securely fastened to the boiler
to prevent boiler from drawing
air from inside the boiler room.
Latches should be secure and
retention screw should be hand
tight.
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.
Contact your installer or tech-
nician immediately if the front
door does not close correctly or
if the door gaskets are damaged.
