Wood-Fired Boiler will burn most solid wood fuels; however, it is recommended
that hardwoods be used for their superior energy content. Burning dry, seasoned wood is also
recommended because a residual moisture content of between 15 and 25% is required for optimal
gasification combustion. The use of dry, seasoned wood will also significantly reduce the
accumulation of creosote in the combustion chamber and heat exchanger.
Use firewood that is that is the appropriate length for your firebox, as referenced in the technical data
firewood will cause “bridging” which will prevent the wood from falling to the bottom of
the burn chamber and could cause gasification to cease. Do not use excessive amounts of wood that
is cut into tiny pieces. This can generate an intense coal bed that could overheat your Boiler. If you
have small scraps to bum, mix them with regular chunk wood. Do not burn driftwood, wood chips,
manufactured logs, sawdust or pellets.
Do not use chemicals or fluids to start the fire or during operation.
Wood-Fired Boiler is designed to burn wood, as detailed herein. Do not burn
garbage, gasoline, naphtha, engine oil, plastic or any item with glue or chemicals.
DO NOT BURN DRIFTWOOD, WOOD CHIPS, MANUFACTURED LOGS, SAWDUST OR PELLETS.
DO NOT BURN GARBAGE, GASOLINE, NAPHTHA OR ENGINE OIL.
If you are having problems with heat outputs, check the moisture content of your wood. Firewood
moisture meters are available on the Internet for minimal cost (typically less than $30) and can save
you a lot of time and energy spent trouble-shooting an easy-to-remedy problem. We cannot overstate
the effect that wood moisture content has on the overall performance of your Boiler.
For maximum efficiency when operating without thermal storage, keep an adequate coal bed
established in the upper chamber while adding only a few pieces of wood at a time to maintain the
desired Boiler temperature. This works well when you're at home and can reduce the overall amount
of wood that is used.
If you wait until the fire has burned to coals before refilling the upper firebox, you will have less chance
of smoke rollback into the Boiler room than if a partial load of wood is still burning inside.
Keep the firebox door tightly closed and check the door seal condition regularly. The 10.3-ounce tube
of high-temperature silicone provided with the Boiler should be used to maintain the integrity the seals
of the pressurized chambers. When applying silicon, use a caulking gun. Squeeze the silicone into the
track (i.e., the indentation on the door seal). A 3/16-inch diameter bead will work best, or approximately
half the diameter of a pencil.
