G. Burner Assembly Cleaning
1. After disconnecting power to the boiler, remove
the boiler's furnace door. For part identification,
refer to the "Arctic Parts Manual".
2. Clean around the burner assembly by blowing
compressed air over the surface of the burner
to remove lint and debris accumulation. Be
careful when cleaning the burner assembly, to
avoid damaging the metal mesh burner surface.
3. If the burner or the burner gasket shows any
visual deterioration or corrosion signs, replace
it immediately.
4. After replacing the burner or burner gaskets,
check for proper operation by performing
combustion analysis, as well as checking for
gas leakage around the burner mounting and
blower transition pieces.
H. Heat Exchanger Cleaning
1. Perform visual inspection of both boiler flue
passes, and remove any debris from the
surfaces of the heat exchanger.

2. If necessary, brush the tubes of the heat
exchanger using non-abrasive, non-metallic
bristle brush.
3. Be careful not to damage or disturb the
insulation inside of the heat exchanger.
I. Tube Replacement Procedure
Performing a regular boiler inspection will prolong
the life of the heat exchanger, and ensure optimal
function and energy efficiency. For best practices,
3
adhere to the general guidelines outlined in the
service and maintenance section of this manual.

1. Inspect the boiler. Use the following steps to
identify a potential tube leak and to minimize
possible damage to the boiler and other
1
equipment as a result of tube failures.
a. Shut off power to the boiler immediately from
the external, dedicated electrical disconnect.
b. Confirm that any water leakage is not the
result of a blocked condensate drain line.
c. Confirm that any water leakage is not the
result of a blocked condensate drain line.
d. Remove the boiler's left side jacket panels
and flue collector access panels as shown in
Figure 17, Figure 18, and Figure 19.
e. Visually inspect the burner and furnace pass
insulation for water damage. If significant
water damage to the insulation or burner is
observed, contact the manufacturer.
f. Identify any leaking tubes.
g. Isolate and drain the boiler completely.
2. Use the proper tools. Use the following tools
to remove and replace leaking boiler tubes:
a. Tube Puller (P/N 106019-02)
b. Tube Driver (P/N 106019-01)
c. Sledgehammer (steel head, approximately
3 lb)
