Trouble Shooting
Problem Cause Solution
Boiler does not come up to
temperature. Improper or wet coal is being used
Wind blowing under boiler Use properly sized, dry coal
Take one or two inches of hard board
insulation and place under boiler between
legs then add non-combustible spacers
between ground to hold up insulation
The boiler is at temperature and is
steaming Poor water circulation (excess fittings,
pump or pipe too small, improper
installation) Change to a larger pump, use min 1” pipe
and sweeping bends instead of 90’s
Poor burn time
Improper or wet coal is being used
Too much demand on unit,
undersized for application Use properly sized, dry coal
Lower home temperature set points, insulate
home better, upgrade to larger boiler
Boiler is up to temperature but little
to no heat in house Poor circulation (A simple test can be
done to determine if this is so: touch the
pex line leaving and returning to boiler.
There should be little or no temperature
difference)
Heat exchanger plugged
Improperly designed installation
Not enough insulation in building Change to a larger pump
Clean with white vinegar – be sure to use NC
boiler treatment to prevent this
Use min 1” pipe, reduce number of 90’s & T’s
used, re-route lines
Add insulation to structure
Boiler over heats Air leak
Blower output damper open too far
Poor circulation
Water is low in boiler
Aqua-stat malfunction
Not enough demand &/or warm weather Make sure doors and covers are sealed &
adjust if necessary
Adjust damper
Larger pump or pipe, reduce # of fittings
Add water to keep full
Replace aqua-stat
Load smaller amounts to prevent large coal
bed from over-producing
Boiler fire does not stay lit Not leaving some coals in burn area
No air flow
Chimney plugged with creosote Load sooner to have more coals
Check the area behind the ash pan to make
sure there is no ash build up that would block
blower air way, replace blower
Clean chimney and extensions/cap
Good coal but does not burn. Only
smolders Holes in floor plugged
Solenoid failed
Blower failed Completely clean ash from all areas of boiler
Check controls, replace failed component
Boiler up to temperature but no
heat in house Circulation pump failed See maintenance section on “pump”
Boiler water getting rusty Not enough or no boiler treatment Have your water tested. Boiler treatment is
required for warranty to be valid. See
warranty.
Blower turns on but solenoid
doesn’t open damper Loose electrical connection
Solenoid failed Turn power off and check all wire
connections
Replace solenoid
Water leaking from boiler Condensation from first start-up of boiler
Condensation from wet coal
Condensation from running below 150F Wait 24 hours to heat up and dry out
Burn only seasoned hardcoal
Adjust aquastat to 165-180 with a 15 degree
differential
Aquastat calling for heat but unit
not running Control switch is off
Failed aquastat Turn on switch
Replace aquastat
