The Controller display is made up of two temperature indicators.
The top numerical indicator is the actual temperature of the water in the Boiler.
The lower numerical indicator displays the desired Boiler water temperature setting. This is controlled
by the increment-decrement buttons on the right side of the display; it will change in 5 degree
increments.
The overheat audible alarm will sound and the control panel display will flash when the unit exceeds
200 degrees Fahrenheit. At the same time a relay will energize for the over temp zone.
The thermo overload/7 amp circuit breaker protects the Control Panel from any electrical shorts or
power surges in excess of 7 amps with any external electrical devices wired through the rear of the
Boiler. This could include the primary or circulating pump, or an overheat valve/pump if installed, and
connected to the electrical box at the rear of the boiler.
In the event of the breaker tripping, the switch will pop outwards. Simply press the switch back into
place to reset the breaker.
WARNING
DO NOT ADD MORE FUEL UNTIL YOU ARE CERTAIN THAT ALL CONTROLS ARE FUNCTIONING
PROPERLY AND NO DAMAGE HAS BEEN DONE TO THE BOILER.
FIRING YOUR BOILER
When first firing the Boiler, use dry kindling and leave the bypass damper open for approximately 15 to
20 minutes. This will allow time to establish the coal bed above the refractory nozzle, which will in turn
yield the most efficient gasification. You will likely find your own routine for firing your Boiler, but this
method works well.
We do not recommend leaving the Boiler off and the bottom door open to get your fire going faster. In
the event that you leave the Boiler and forget to close the door, the fire will grow to the point that the
Boiler overheats and produces steam.
As a starting point, set the temperature controller approximately 10 to 15 degrees below the
temperature you would like your system to operate. Unlike gas or oil fired boilers, when the
ECONOBURN
TM
Wood-Fired Boiler goes into stand-by mode, its temperature will continue to rise until
the lack of combustion air slows the fire enough to stabilize the water temperature. This setting will
vary from system to system and will be dependent upon the size of your Boiler, the amount of water in
the system, the time of year, and the heat load on the Boiler.
COMBUSTION AIR SUPPLY & NEGATIVE AIR PRESSURE
An adequate flow of air to the Boiler must exist at the location where the Boiler is to be installed in
order to ensure proper combustion and to maintain safe ambient room temperatures. For Boilers
located in a confined space, or in an unconfined space in a building or structure of unusually airtight
construction, outdoor air must be provided.
