TROUBLESHOOTING
If the furnace is running but fails to bring water up
to temperature:
1. Check fire.
2. Check fan for operation.
3. Check that the solenoid damper and fanbox elbow
is open to allow air injection.
4. Check to ensure the furnace is sized accurately
according to heat demand.
5. Check fuel type. Poor quality fuel will not provide
as many BTU’s as high quality fuel.
6. Check water level of furnace.
7. Check for ash and creosote blockage at chimney
and bypass trough.
8. Check temperature settings. Make sure high
temperature setting is set to at least 165 F.
9. Check for power at furnace.
10. Check to ensure all pumps in the system are
running.
11. Check to make sure there are no leaks, hot/wet
spots on your ground or breaks in the pipe or
fittings which may cause the pipe to be saturated
and lose its insulation value.
12. Check Temperature of water exiting furnace,
entering the building being heated and before and
after each heat exchanger.
If the furnace water is hot but buildings do not have
heat:
1. Check to ensure all pumps in the system are
running.
2. Check filter cartridge for flow blockage (if
installed).
3. Check for air in the system at the exchanger by
bleeding off.
4. Check for closed valves to ensure water flow.
5. Check Temperature of water exiting furnace,
entering the building being heated and before and
after each heat exchanger.
If the furnace overheats:
1. Check that all doors are closing properly and that
door gasket is completely sealing.
2. Check that the solenoid damper plate is opening
and closing without hang-ups.
3. Check venting and fan box on rear of furnace for
air leaks.
• Cleaning of the heat exchanger, flue pipe, chimney
and draft inducer if used, is especially important
at the end of the heating season to minimize
corrosion during the summer months caused by
accumulated ash.
Creosote and Fly Ash Formation and Need
for Removal.
ATTENTION: Have a clearly understood plan to
handle a runaway fire or chimney fire
When coal is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture
to form creosote. The creosote vapors condense in
the relatively cool chimney flue of a slow-burning
fire. As a result, creosote residue accumulates on
the flue lining. When ignited, this creosote makes an
extremely hot fire. The chimney and chimney connector
should be inspected at least twice monthly during the
heating season to determine if a creosote buildup has
occurred. If creosote has accumulated it should be
removed to reduce the risk of a chimney fire.
Disposal of Ashes - Ashes should be placed in a
metal container with a tight fitting lid. The closed
container should be placed on a non-combustible
floor or on the ground well away from all combustible
materials before final disposal. If the ashes are
disposed of by burial in soil or otherwise locally
dispersed, they should be retained in the closed
container until all cinders have thoroughly cooled.
CAUTION: Make certain that all electrical power to
the furnace and components is shut off. It can be
washed using water and a mild non abrasive cleaner
suitable for painted surfaces.
ATTENTION:
Avoid direct water pressure to electrical
components and connections.
