out from the top and close the door, restore power and re-install the sheet metal cover.
10. If not equipped with the optional flue clean out remove four sheetmetal screws that hold top jacket
on boiler
11. Shut off boiler power and quickly remove flue pipe and remove sheet metal and insulation from top
of boiler. Re-connect flue pipe and power boiler back on for the following two steps.
12. Tools needed for next steps include: a shop vacuum with HEPA filter, 9/16” deep socket on ¼” drive
ratchet or cordless drill motor, bright flashlight or drop light.
13. Remove the four 9/16” brass nuts from boiler flue pipe adapter cover.
14. Make sure shop vac and light source are plugged in and ready to go.
15. Shut off boiler power and remove flue pipe and set to the side, vacuum each tube and then move
economizer up and down so as to loosen any remaining fly ash and re-vacuum that tube, inspect
each tube with the light and verify free of obstructions and clear of most of the fly ash.
16. Replace cover and flue pipe, re-apply boiler power and re-install the four 9/16” nuts.
17. Shut off boiler power and quickly remove flue pipe and install sheet metal and insulation to top
of boiler. Re-connect flue pipe and power boiler back on
Resolution of Common Problems
1. If there is black dust evident on the horizontal surfaces in the home, shut down the fan and try
adding the coal to the hopper more slowly, or get oiled coal. Check your coal supply, if there are
many small broken pieces and dust mixed in, try an alternate source to see if cleaner coal is
available.
2. A moist hopper lid indicates a draft issue that must be resolved immediately. Make sure all flue
pipes are clean, ensure that the barometric damper is adjusted properly and is not stuck open, ensure
that the coal is not dripping wet when added to the hopper, check that the chimney is not restricted
if the preceding items do not correct the issue. If the boiler is on a power vent ensure that the unit
has been maintained per the manual and is spinning fast enough to provide sufficient draft.
3. A coal fire that is burning toward the back of the grate is indication of insufficient or too much draft
and must be resolved immediately. Check all items in paragraph 2, if all those items are not the
source of
the issue, shut the boiler down and check the fiberglass gasket that is between the back edge of the
grate and feeder body. This gasket will often fall out when the grate is removed and must be replaced
if missing.
4. If the combustion fan or feeder motor stop operating, Provide 120VAC to the motor directly to verify
that the issue is not with the boiler wiring or controls. Often a motor will stop operating after the
boiler is shut down even after a power outage, cleaning the motor and oiling the bearings will often
solve the issue.
CAUTION: EXCESSIVE CORROSION WILL REULST FROM BOILER SHUT DOWN FOR MORE THAN A WEEK
WITHOUT PROPERLY CLEANING AND PROTECTING THE SURFACE EXPOSED TO COAL ASH. THE
RESULTING CORROSION WILL VOID THE WARRANTY ON THE PRESURE VESSEL.
Boiler Shut Down and End of Season Maintenance
1. It is recommended that the boiler be run and kept at operating temperatures year round. If a shut
down of the unit is required for any reason the following steps should be taken. After the boiler is
cool remove all unburned coal from the hopper, and remove the ash pan from the boiler. Remove all
ash off the grate and vacuum the inside of the boiler using a shop vac fitted with a HEPA filter to
