Maintenance As Outlined Below Can Be
Performed By Owner Unless Otherwise Noted.
• The acidic nature of fl ue gasses condensing on
aluminum boiler sections may cause formation of
aluminum oxide. This oxide formation is normal,
is generally uniform throughout boiler sections,
and represents negligible mass of aluminum that is
consumed by oxidation during life of the boiler.
• If left unchecked, this buildup may eventually cause
blockage of fl ue gas passages in boiler sections,
reducing ef fi ciency, and ultimately shutting down the
boiler due to lack of combustion air fl ow.
• Regular service and maintenance by a quali fi ed service
agency must be performed to assure safe trouble free
operation and maximum ef fi ciency.
Beginning Of Each Heating Season
1.
Annual service call by quali fi ed service agency, which
includes:
A. Examine fl ue passages between boiler sections,
burner, and condensate lines, and clean if
necessary following “Annual Examination And
Cleaning Of Boiler Components” on page 48 .
B. Visually inspect venting and air intake system
for proper function, deterioration or leakage. If
vent or air intake show any signs of deterioration
or leakage, repair or replace them, immediately.
Insure proper reassembly and resealing of vent and
air intake system
C. Check for and remove any obstruction to fl ow of
combustion air or venting of fl ue gases. Check air
baf fl e located inside 1½” x 2” fl exible coupling on
mixer, clean if necessary and make sure to put it
back. Refer to repair parts diagram of mixer and
pressure switch assembly for exact location.
D. Follow instructions for “Operating Instructions” on
page 37 .
E. Follow instructions for “veri fi cation Procedure and
Adjustment” on page 42 .
F. Visually inspect condensate drain lines for proper
operation and deterioration. Check for plugged
condensate drain lines.
G. Check silicone rubber seals between boiler sections.
Insure that there are no leaks. Use RTV silicone
rubber adhesive sealant rated for at least 400° F to
replace or repair seals in locations where original
seals have deteriorated.
H. Check all gasketed joints for leakage, and tighten
bolts or replace gaskets if necessary.
I. Remove jacket front and top panels and check for
piping leaks around relief valve and other fi ttings.
Repair, if found. DO NOT use stop leak compounds.
J. Check igniter for cracks and deterioration. Replace
if necessary.
K. Check for water in pressure switch tubing. Drain if
necessary.
2.
Check boiler area is free from combustible materials,
gasoline, and other fl ammable vapors and liquids.
3.
Circulator pump and blower motor furnished with boiler
are permanently lubricated from factory and require no
further lubrication. Additional or non-factory supplied
pumps and/or motors should be lubricated according to
the pump and/or motor manufacturer’s instruction.
Daily During Heating Season
1.
Check for and remove any obstruction to the fl ow of
combustion air or venting of fl ue gases.
2.
Check boiler area is free from combustible materials,
gasoline, and other fl ammable vapors and liquids.
MAINTENANCE AND CLEANING
Monthly During Heating Season
1.
Remove jacket front and top panels and check for
piping leaks around relief valve and other fi ttings. If
found, contact quali fi ed service agency to repair. DO
NOT use stop leak compounds.
2.
Test relief valve. Refer to valve manufacturers
instructions packaged with relief valve.
3.
Visually inspect venting and air intake system for
proper function, deterioration, or leakage. If vent or
air intake show any signs of deterioration or leakage,
contact a quali fi ed service agency to repair or replace
immediately and to insure proper reassembly and
resealing of vent and air intake system.
4.
Visually inspect clear vinyl condensate lines and PVC
condensate drain pipe for proper operation, leakage,
and deterioration. If condensate lines or drain pipe
show any signs of blockage, leakage, or deterioration
contact a quali fi ed service agency to clean, repair, or
replace them immediately.
Periodically During Heating Season
Where low water cutoffs are used, periodic inspection of
low water cut off is necessary, including fl ushing of fl oat
type devices. Refer to low water cut off manufacturer’s
speci fi c instructions.
End of Each Heating Season - Annual Shutdown
Procedure
Follow instructions “To Turn Off Gas To Appliance” on page
37 .
If heating system is to remain out of service during
freezing weather, and does not contain antifreeze, drain
system completely. If boiler will be exposed to freezing
temperatures, drain condensate lines. Otherwise, do not
drain system or boiler.
