Blower will not come on. High limit switches may be shut off
because the water temperature is higher
than aquastat setting permits.
Wait for the water to cool down. Reset
snap disc, see page 8.
No electricity. Check power supply.
Blower overheated. Wait for blower to cool down.
Blower is on but no air in firebox. Flapper unit flap stuck shut. Force flap open. Clean and oil flap. To
remove flapper unscrew blower bolts.
The water overheated and boiled over.
After refilling the water, temperature is
below operating range, but there is no
power coming through to the blower.
The high limit switch (snap disc) has
tripped the circuit.
The high limit switch (snap disc) has a
manual reset. Press button to reset. To
locate snap disc see page 8.
There is some smoke coming from the
chimney most of the time.
Wood is too dry or bridged. Burn only seasoned wood. Reposition
wood.
Water temperature is too low. Reduce heat draw from furnace allowing
the water temperature to reach at least
160°F (71°C).
Furnace overheats and boils. Main door has been left open. Close door.
Main door and/or ash clean out gaskets
are leaking.
Replace gaskets or adjust latches and/or
hinges.
Low heat output. Wood moisture is too high causing the
wood to bridge. Note: when bridging hap-
pens there is an air space between the
wood and the firebox floor. The air then
exits the firebox without causing the wood
to burn.
Use seasoned wood. Cut wetter pieces 8
inches (20 cm) shorter than the firebox
and load the logs centered in the firebox.
Split the bigger logs. Place the logs care-
fully so they will not bridge.
Fire has almost died out before refuelling. Add wood before the fire has burned
down.
Wood is hung up and bridged because of
incorrect length and loading.
Place logs centered over the brick slots/
air passage on the firebox floor.
Low heat output. The brick slots/air passage in the firebox
floor is blocked by charcoal/ash.
Using the ash rake, always stir the firebox
charcoal/ash into the lower ash chamber
before adding wood. Limit the charcoal/
ash buildup and let the charcoal burn
down before adding wood.
It is difficult to get a fire started. Brick slots on the floor of the firebox are
blocked.
Place small pieces of wood so air can flow
through. Avoid flat pieces of wood that
could block the air when laid flat on the
firebox floor. As you add more wood place
the wood so air can flow through.
Fire dies out with wood still left in the
firebox.
The furnace has been on the off cycle for
too long causing the wood to bridge or
hang up.
Flapper is stuck shut from the furnace
idling too much.
In spring/fall when one load of wood lasts
more than 16 hours do not fill up the
firebox.To further avoid bridging, stack the
wood so the lowest part of the stack is in
the centre. In spring/fall use only 6 inch (15
cm) diameter and smaller seasoned logs.
Not drawing enough heat from the furnace. Increase the heat draw on the furnace.
