MAINTENANCE
E. ANNUALLY (BEFORE START OF HEATING
SEASON)
1. Check flueways and burners for cleanliness and
clean if necessary. Use the following procedure if
cleaning is required:
a. Refer to the Operating Instructions in Figures 8.3
& 8.4 to properly turn off the gas to the boiler.
b. Turn off all electrical power to the boiler.
c. Remove burners and brush gas outlet ports
lightly using a soft bristle brush.
d. Remove the vent pipe, automatic vent damper (if
used), draft hood, top jacket panels, flue collector
and flue baffles.
e. Brush flueways with wire brush.
f. To the extent possible, inspect inside of vent
pipe and vent damper for obstructions in flow or
vent damper movement. Remove or replace as
necessary.
g. Re-install baffles. When replacing the flue
collector, be certain that the blanket seal between
the flue collector and top section makes a
tight seal to prevent leakage of the products of
combustion.
h. Re-install the top of the jacket, draft hood, vent
damper (if used) and vent pipe.
i. Connect blocked vent switch wiring harness to
blocked vent switch.
k. Re-install burners.
2. Inspect entire venting system for corrosion, support
and joint integrity. Repair as necessary.
3. Check the pilot and main burner flame. See Figure
10.1. The pilot should provide a steady flame
enveloping 3/8” to 1/2” (10 mm to 13 mm) of the
flame sensor. If required, adjust the pilot as stated in
the gas valve manufacturer’s instructions. The main
burner flame inner cone should be approximately
1-1/2” (40 mm) high and should have a very sharp,
blue color characteristic.
4. Systems with antifreeze. Check for correct
concentration and inhibitor level.
