Cleaning boiler flue ways

The boiler contains ceramic fiber and fiberglass materials.
Use care when handling these materials per instructions
on page 48 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.
Make sure all electrical connections to boiler are turned
off and wait until boiler is warm, not hot, before clean-
ing. Failure to do so will result in severe personal injury,
death or substantial property damage.
1. Top flue boilers -remove breeching and jacket top panel. Rear flue
boilers - 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
wall of rear refractory.
6. Move to the bottom of the flue ways and clean up between the
sections to reach pins left uncleaned in Step #5.
7. Once the flue ways are cleaned, carefully remove the paper from
the floor of the combustion chamber.
8. Verify sealing rope around flue area is intact. Visually check condi-
tion 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 leak-
age and carbon monoxide emissions, which can lead to
severe personal injury or death.

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 10 of this manual. If any of these are pres-
ent 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.

Thoroughly clean flue ways between all
pins at all angles Start on top of boiler,
finish from the bottom
Wear a NIOSH -certified dust respirator (N95)
while cleaning the boiler, per WARNING on
page 48. Failure to comply could result in
severe personal injury.

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, over-
heating cast iron, and causing section failure. Leak-
ing water may also cause severe property damage.
