Cleaning boiler flueways
The boiler contains ceramic fiber and fiberglass
materials. Use care when handling these materials
per instructions on page 28 of this manual. This
boiler contains ceramic fiber and fiberglass materials
that have been identified as carcinogenic, or possibly
carcinogenic, to humans).
Failure to comply could
result in severe personal injury.
Figure 14 Cleaning boiler flueways — Thoroughly
clean flueways between all pins at all
angles. Start on top of boiler, finish from the
bottom.
Make sure all electrical connections to boiler are
turned off and wait until boiler is warm, not hot,
before cleaning. Failure to do so will result in severe
personal injury, death or substantial property damage.
1. Remove jacket top panel.
2. Remove flue collector hood, saving hardware for reassembly.
3. Shut off oil valves. Arrange drip pans under the areas of oil
piping that will be disconnected. Disconnect oil line at burner
so that you can swing open the door completely.
4. Line combustion chamber floor with newspaper to catch any
soot that will be loosened in the cleaning process.
5. Starting at the top of the boiler, use a wire flue brush to
thoroughly clean between all pins at all angles. Be careful not
to damage side walls of rear refractory.
6. Move to the bottom of the flueways and clean up between the
sections to reach pins left uncleaned in step #5.
7. Once the flueways are cleaned, carefully remove the paper
from the floor of the combustion chamber. Fold the paper to
capture the refuse, seal in a plastic bag, and dispose.
8. Verify sealing rope around flue area is intact. Visually check
condition and position of insulation in combustion chamber
floor, and the refractories at the rear of boiler and in the burner
mounting door. Replace any parts as necessary.
9. Close burner mounting door and tighten nut securely. Place
flue collector hood on top of boiler. Secure with hardware from
step #2. Maintain a gas-tight seal to avoid possible flue gas
leakage and carbon monoxide emissions, which can lead to
severe personal injury or death.
10. Check breeching for sooting and clean if necessary. Install
jacket top panel and breeching.
11. Reconnect oil line and all electrical connections.
Wear a NIOSH -certified dust respirator (N95) while
cleaning the boiler, per WARNING on page 28. Failure
to comply could result in severe personal injury.

Reported problems
Inspect any problems reported by owner and correct before
proceeding.
Boiler area
1. Verify that boiler area is free of any combustible materials,
gasoline and other flammable vapors and liquids.
2. Verify that boiler area is free of any of the contaminants listed
in Table 2 on page 5 of this manual. If any of these are present
in the boiler intake air vicinity, they must be removed. If they
cannot be removed, install combustion air piping to the boiler
in accordance with national, provincial or local codes.

Piping
1. Check the boiler interior piping and all system piping for signs
of leaks.
2. Repair any leaks before proceeding.
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to boiler
will occur, resulting in substantial property damage.
Eliminate all system or boiler leaks. Continual
fresh makeup water will reduce boiler life. Minerals
can build up in sections, reducing heat transfer,
overheating cast iron, and causing section failure.
Leaking water may also cause severe property
damage.
