Maintenance
as outlined
below can be performed
by the owner unless otherwise noted.
The acidic nature of flue gasses condensing
on the aluminum
boiler sections will cause the
formation
of aluminum oxide.
This oxide formation
is normal,
is generally
uniform throughout
the
boiler sections,
and represents
a negligible
mass of aluminum that is consumed by oxidation during the
life of the boiler.
If left unchecked,
this buildup may eventually
cause blockage of the flue gas
passages
in the boiler sections,
reducing
efficiency,
and ultimately
shutting down the boiler due to
lack of combustion
air flow.
Regular
service and maintenance
by a qualified
service agency must
be performed
to assure
safe trouble
free operation
and maximum
efficiency.
A. BEGINNING
OF EACH HEATING
SEASON
1.Annual
service call by a qualified service agency,
which includes:
a.
Examine flue passages between
boiler sections, burner,
and condensate
lines, and clean if
necessary
following
the annual examination
and cleaning instructions
in paragraph
"F" on
the next page.
b.
Visually
inspect venting and air intake system for proper
function,
deterioration
or
leakage.
If the vent or air intake show any signs of deterioration
or leakage, repair or
replace them immediately.
Insure proper reassembly
and resealiug
of the vent and air
intake system.
c.
Check for and remove any obstruction
to the flow of combustion
air or venting of flue
gases.
Check the air baffle located inside 1Vz"x2" flexible coupling on the mixer,
clean it 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 "PLACING
BOILER IN OPERATION".
e.
Follow instructions for "CHECK
OUT PROCEDURE
AND ADJUSTMENTS".
f.
Visually inspect condensate drain line for proper operation and deterioration.
Check for
plugged condensate drain line.
g.
Check the silicone rubber seals between boiler sections.
Insure that there are no leaks.
Use RTV silicone rubber adhesive sealant (available
in caulking gun tubes) 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 fittings.
Repair,
if found.
DO NOT use stop leak compounds.
2.
Check that boiler area is free from combustible materials, gasoline, and other flammable
vapors and liquids.
3.
Circulator pump and blower motor furnished with boiler are permanently
lubricated from the
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.
B. DALLY DURING
HEATING
SEASON
1.
Check for and remove any obstruction to the flow of combustion
air or venting of flue gases.
2.
Check that boiler area is free from combustible
materials,
gasoline,
and other flammable
vapors and liquids.
