SECTION 9.
9A. Maintenance
1. Lubricate the water circulating pump per the
instructions on the pump.
2. If a strainer is employed in a pressure reducing
valve or the piping, clean it every six months.
3. At start-up, and periodically thereafter, the burner
and pilot flames should be observed. If the flame
has the appearance of “sooting” tips, check
for debris near the orifices and call the service
technician.
4. Ensure proper operation of the mechanical
damper, mounted in the flue collar, by observing
the damper handle. Be sure the handle swings
when the draft inducer starts (depending on
the boiler size, swing may be as little as 30°).
Remove any obstructions and clean around the
pivot rod (handle) holes.
5. Inspect the venting system for obstruction,
leakage or corrosion at least once a year.
6. Keep the boiler area clear and free from
combustible materials, gasoline, and other
flammable vapors and liquids.
7. Be sure that all combustion air and ventilation
openings are unobstructed.
8. Upon completion of the installation, inspect
the external surfaces of the heat exchanger for
fouling based on the following schedule:
24 hours - 7 days - 30 days - 90 days
Once every six months thereafter.
9. If the boiler is not going to be used for long
periods of time in locations where freezing
occurs, it should be completely drained of
all water. To accomplish this, there is a drain
valve on the right side of the boiler which can
be opened. This will drain the right side of the
boiler. There are two plugs located on the left
side of the heater which must be removed to
drain that side. Both sides must be drained.
10. The gas and electric controls on the boiler
are engineered for long life and dependable
operation, but the safety of the equipment
depends on their proper functioning. It is strongly
recommended that the basic items listed below be
inspected by a qualified service technician every
year.
a. Water temperature controls.
b. Pilot safety system.
c. Automatic gas valves.
d. Fan proving switch.
e. Inducer/Blower assembly.
f. Mechanical flue damper operation.
WARNING
The Warranty does not cover damage caused by
lack of required maintenance, lack of water flow,
or improper operating practices.
AVERTISSEMENT
La garantie ne couvre pas les dommages causés
par l'absence d'entretien, absence de débit d'eau,
ou pratiques de fonctionnement irrégulières
Fouling on the external surfaces of the heat exchanger
is caused by incomplete combustion, and is a sign
of venting and/or combustion air problems. The heat
exchanger can be inspected by using a flashlight
and placing a mirror under the burners. An alternate
method is to remove the venting and top panel to
inspect the exchanger from above. The vent system
should be inspected at the same time. If cleaning is
required:
a. Shut off all power to the boiler.
b. Remove the venting top, flue collector,
draft inducer assembly, and heat exchanger
baffles.
c. Remove the burner tray.
d. Use a hand-operated spray bottle filled with
water, and a wire brush to clean soot and
loose scale from the underside of the heat
exchanger. DO NOT USE COMPRESSED
AIR, HIGH PRESSURE WATER, OR A
GARDEN HOSE.
e. Clean any fallen debris from the bottom of
the unit.
f. Check to make sure the burner ports and
pilot assembly are free of debris before
returning the burner tray to its original
position.
g. Reassemble the boiler in reverse order,
making sure to replace the heat exchanger
baffles.
