VI. Trouble Shooting
Problem
Cause
Solution
Boiler does not come up to temperature.
Green or soft wood is being used,
Wind blowing under boiler
Use dry, hard wood
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, too
small of pipe, improper installation)
Change to a larger pump, use sweeping bends
instead of 90’s
Poor burn time
Green or soft wood is being used,
Damper is open too far, too much demand
on unit
Use dry, seasoned hard wood
Adjust damper to highest position, lower
temperature set points
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 and add a y-strainer – be sure to use
treatment!
Reduce number of 90’s & T’s used
Add insulation to structure
Boiler over heats
Air leak
Damper open to far
Poor circulation
Water is low in boiler
Aqua-stat malfunction
Make sure loading door is sealed & adjust if
necessary, make sure ash pan is shut
Adjust damper to highest point
Larger pump, reduce # of fittings
Add water to keep full
Replace Aqua-stat
Boiler fire does not stay lit
Not leaving some coals in burn area
No air flow
Leave some coals in burn area
Check the area behind the ash pan to make sure
there is no ash build up that would block blower
air way, replace blower
Good wood but does not burn. Only
smolders
Blower air way plugged
clean air way
Boiler up to temperature but no heat in
house
Circulation pump failed
Remove screw on top of pump to see if shaft is
spinning. If not
turn power off
& turn shaft with
screw driver until loose. Turn power on & check
to see if shaft is spinning. If not, replace pump.
Pump has a one year warranty and must be
returned to dealer for replacement
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.
Solenoid opens damper but blower
won’t come on
Blower burned out
Replace blower
Blower turns on but solenoid does not
open
Loose electrical connection
Solenoid burned out
Turn power off
and check all wire connections
Replace solenoid
Water leaking from boiler
Condensation from first start-up of boiler
Condensation from wet wood
Wait for water to come up to temperature
