In order to get peak performance out of your Blaze King furnace you will need to follow a few basic steps
outlined in the following chapters. Forget everything you learned about how to burn or operate a regular
wood furnace. You cannot just throw in some newspaper and a log or two, light a match and expect your
Blaze King to work the same way an inefficient wood furnace would. Your Blaze King was designed to
burn more efficiently, saving you time and money.
BYPASS
All catalytic wood burning appliances have a bypass device for allowing the smoke from the fire to
temporarily bypass, or go around, the catalyst. The bypass is located inside the top front of the firebox.
The bypass is a steel plate door, hinged inside the furnace, and is controlled by the bypass handle on
the left or right side of the furnace. When the handle is lifted up, the bypass is open, when pushed down,
it is closed.
Other than during the initial startup sequence, DO NOT burn the furnace with the by-pass open. Leaving
the by-pass open may APPEAR to achieve a hotter fire, but in fact, just the opposite is true. Bypassing
the catalyst allows as much as 50% of the potential fuel - and therefore heat - to go directly up the
chimney. This Blaze King catalytic furnace produces the greatest amount of heat when the by-pass is
closed, and the catalyst is active.
The bypass system also contains a built in switch which reduces the combustion air when the bypass is
opened to avoid over firing.
See page 35 for adjusting bypass handle and gasket.
CATALYTIC MONITOR (THERMOMETER)
This monitor is located on the side of the furnace. It purpose is to show you the temperature of the
catalyst. Depending on the temperature you know if the catalyst is active or not. Press the red button
and the catalyst temperature will be displayed for 30 minutes. When temperature is below 500 F,
“COOL” will be displayed.
FUEL
Blaze King recommends using dry seasoned wood, split and stacked and protected from rain for at least
24 months with a moisture content of 13% or lower. It takes a great deal of energy to evaporate the
moisture contained in green wood and that energy will not be heating your house. Also, green or wet
wood will greatly increase creosote & combustor problems. Blaze King moisture meters are available at
your Blaze King dealer.
Our wood furnaces are not designed for burning coal and doing so will void the warranty.
Never burn salt-water driftwood. It is very corrosive and will damage the firebox. Burning salty wood also
voids the warranty.
This controlled combustion firebox has been designed for high efficiency and long burn times. The
proper time to add more wood is when the last charge has been reduced to a glowing charcoal bed.
There will be very little smoke at this stage in the burn cycle.
WARNING: BURNING WET UNSEASONED WOOD CAN CAUSE EXCESSIVE CREOSOTE
ACCUMULATION. WHEN CREOSOTE IS IGNITED IT CAN CAUSE A CHIMNEY FIRE WHICH MAY
RESULT IN A SERIOUS HOUSE FIRE.
