Detailed service procedures
Cleaning boiler flueways
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 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.
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.
10. Check breeching for sooting and clean if necessary. Install jacket
top panel and breeching.
11. Reconnect oil line and all electrical connections.
