Maintenance procedures — DAILY
Check the boiler area
To prevent potential of severe personal in-
jury, death or substantial property dam-
age,
eliminate all materials discussed
below
from the boiler vicinity and from
the vicinity of boiler combustion air inlet.
If contaminants are found:
• Immediately remove products 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 corro-
sion.
• If products cannot be removed, im-
mediately call a qualified service
technician to re-pipe vent (and air)
piping and locate vent termination/
air intake away from contaminated
areas.
Combustible/flammable
materials
Do not store combustible materials,
gasoline or any other flammable vapors
or liquids near the boiler. Remove im-
mediately if found.
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 con-
tinue. 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 termina-
tion) must be relocated to another area.
Check the pressure/temperature
gauge
1. Make sure the pressure reading on the boiler pres-
sure/temperature gauge does not exceed 80 psig
(or no higher than the 5 psig less than the relief
valve setting).
2. Contact a qualified service technician if pressure
is too high.
DIRECT EXHAUST installations:
Verify combustion air openings are clear and
flue is unobstructed
1. DIRECT EXHAUST INSTALLATIONS (air piped to the boiler from
outside)
a. Visually inspect all combustion air openings.
b. Remove any debris or blockage from combustion air louvers.
The combustion air openings must be unobstructed. This is
the means for combustion and ventilation air to be drawn
into the boiler room.
Failure to provide proper combustion air can result in severe
personal injury, death or substantial property damage.
2. Verify that boiler vent discharge is clean and free of obstructions.
3. Remove any debris on the flue exhaust openings.
4. If removing the debris does not allow the boiler to operate correctly
afterwards, contact your qualified service technician to inspect the
boiler and vent/air systems.
DIRECT VENT installations:
Verify boiler front door is securely closed and
vent/air terminations are unobstructed
1. DIRECT VENT INSTALLATIONS (air piped to the boiler from outside)
c. Visually inspect the boiler jacket door to be sure it is sealed all
around its perimeter.
d. Verify that the two rotary latches on top are tight.
e. Re-install the jacket door after service or maintenance.
The boiler jacket 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.
Contact your installer or technician immediately if the jacket
door does not fit correctly in place or if the door gaskets are
damaged.
2. Verify that boiler vent discharge and air intake are clean and free of
obstructions.
3. Remove any debris on the air intake or flue exhaust openings.
4. If removing the debris does not allow the boiler to operate correctly
afterwards, contact your qualified service technician to inspect the
boiler and vent/air systems.
