boiler are permanently lubricated from the factory and
require no further lubrication. Additional or non-factory
supplied pumps and/or motors should be lubricated ac-
cording to the pump and/or motor manufacturer’s in-
struction.
Daily during heating season
Check for and remove any obstruction to the flow of
1.
combustion air or venting of flue gases.
Check that boiler area is free from combustible materi-
2.
als, gasoline, and other flammable vapors and liquids.
monthly during heating season
Remove jacket front and top panels and check for
1.
piping leaks around relief valve and other fittings. If
found, contact a qualified service agency. DO NOT
use stop leak compounds.
Test relief valve. Refer to valve manufacturers instruc-
2.
tions packaged with relief valve.
Visually inspect the venting and air intake system for
3.
proper operation. If the vent or air intake show any
signs of deterioration or leakage, contact a qualified
service agency to repair or replace them immediately
and to insure proper reassembly and resealing of the
system.
Visually inspect the PVC condensate drain pipe for
4.
proper operation. If the drain pipe shows any signs of
blockage, leakage, or deterioration contact a qualified
service agency to clean, repair, or replace it immedi-
ately.
Check air vent(s) for leakage.

A periodic inspection of the low water cut off is neces-

sary, including flushing of float type devices. Refer to
low water cut off manufacturer’s specific instructions.
annual shut down procedure
Turn off gas to boiler as described
1.
“To Turn Off Gas
To Appliance”
in Section V of the Control Manual and
Operating Instructions (P/N# 240006104).
The acidic nature of flue gases condensing on the alumi-
num 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 shut-
ting down the boiler due to lack of combustion air flow, or
drainage of condensate.
Regular service and maintenance by a qualified
service agency must be performed at least once
every 12 months to assure safe, trouble free op-
eration and maximum efficiency.
Beginning of each heating season
Schedule an annual service call by a qualified service
1.
agency which includes:
Examining flue passages in the heat exchanger, burner,
•
and condensate lines, and cleaning (if necessary) by fol-
lowing the instructions in “Annual Examination and Clean-
ing of Boiler Components” in this section.
Visually inspecting the venting and air intake system for
•
proper operation, immediately repairing or replacing any
sign of deterioration or leakage, and insuring proper reas-
sembly and resealing of the system.
Checking for and removing any obstruction to the flow of
•
combustion air or venting of flue gases.
Following the instructions in Sections V and VII of
•
the Control Manual and Operating Instructions (P/N#
240006104), “Putting The Boiler In Operation” and
“Checkout Procedures And Adjustments.”
Visually inspecting the condensate drain line for proper
•
operation and checking for deteriorated or plugged con-
densate drain line.
Checking all gasketed joints for leakage and tightening
•
bolts or replacing gaskets as needed.
Removing jacket front and top panels, checking for piping
•
leaks around relief valve and other fittings, and repairing if
found WITHOUT USING stop leak compounds.
Analyze the boiler fluid as instructed in Water Treatment
•
and Freeze Protection section of manual 240006104.
Check that boiler area is free from combustible materi-
2.
als, gasoline, and other flammable vapors and liquids.
