STORAGE OF WOOD
Do not store wood within installation clearances or within the space required for charging or ash
removal.
INSPECTION & CLEANING
During daily wood fuel loading, stoking of the wood in the upper chamber (also referred to as the
“firebox chamber”) should cause most ash to fall through the nozzle to the bottom chamber (also
referred to as the “lower combustion chamber”). Any dead ash that has not fallen through the nozzle
should be removed from the upper chamber. Ash acts as an insulator and will retard performance.
Check the bottom chamber weekly for ash buildup until experience shows how often cleaning is
necessary.
Be aware that hotter fires yield greater boiler performance, higher efficiency, and
reduced maintenance. It is recommended that horizontal flue runs be inspected mid-season for
any accumulated ash that may have been entrained in the combustion stream and settled-out in
the flue runs.
THE FLUE DRAFT CONTROL SYSTEM
The ECONOBURN
TM
Wood-Fired Boiler has been designed so that the firebox door latch remains
locked, preventing the firebox door from opening unless the flue draft handle (see Figure 1) is first
pushed inward as far as it will go toward the rear of the unit. This opens the bypass damper. Opening
this bypass damper depressurizes the upper burn chamber and forces the smoke and flue gasses
directly up the chimney, thereby preventing a surge of smoke and/or flames toward the operator when
the firebox door is opened.
The forced draft fan must be stopped (via the toggle switch on the blower box; see Figure 10) and the
rear damper fully opened for at least one minute before opening the firebox door to refuel.
DO NOT RUN THE BOILER WITH THE FLUE DAMPER IN THE OPEN POSITION.
Running with the damper in the open position will damage the water jacket.
WARNING
NEVER OPEN EITHER DOOR ON THE UNIT (EITHER THE UPPER FIREBOX DOOR OR THE
LOWER COMBUSTION CHAMBER DOOR) WHEN THE BOILER IS IN OPERATION WITHOUT (1)
OPENING THE REAR DAMPER BY PUSHING THE FLUE DRAFT HANDLE ALL THE WAY
TOWARD THE BACK OF THE UNIT, (2) TURNING THE FORCED DRAFT FAN OFF, AND (3)
WAITING A MINIMUM OF ONE MINUTE.
