OPERATING INSTRUCTIONS
YOUR FIRST FIRE!
The following pages contain information on the operation of the major components on your Blaze King
appliance. Please take the time to read through this section as it will give you a better understanding of how
your appliance works. This understanding will help you to operate your appliance at its optimum level thus
extended its life while allowing you to get the highest efficiencies from your heater.
EFFICIENCY
Efficiency was determined using the method outlined in B415.1-10 test method. It is represented by the Higher
Heating Value (HHV) as the fuel used during testing contains between 19% - 25% water moisture included in
the total calculated fuel weight. (Other test methods such as LHV or Low Heating Value, do not take the water
moisture into account).
Annual Fuel Utilization Efficiency (AFUE) attempts to represent the actual, season long, average efficiency of
an appliance. HHV is the actual, calculated average efficiency obtained under test conditions. Using correctly
seasoned wood is important when trying to gain efficiency. The more seasoned (dry) the wood, the higher the
efficiency (less energy wasted on eliminating moisture during combustion). Operating your Blaze King at lower
settings will result in higher efficiencies as the fuel will undergo a more complete combustion.
FAN OPERATION
The fans are located beneath the firebox of the appliance. They recirculate room air up the back of the firebox
and out across the top. This design allows the air to travel the furthest distance across the hot surfaces
resulting in super heated air. The fans should be turned off until the appliance reaches normal operating
temperatures. After approximately 30 minutes, the fans can be turned on and the speed adjustment should
match the thermostat control setting, i.e. if your appliance is set at medium then your fan should also be set at
medium, low—low, high—high etc. The fan control is located on the lower side of the outer right casting.
INTRODUCTION
All Blaze King free standing wood appliances are designed as radiant room space heaters. They have been
designed and tested to be installed in insulated habitable rooms areas of your dwelling. The appliance has
not been designed to be installed in a concrete uninsulated basement or in a shop/garage environment. Such
applications may cause the thermostat to be unresponsive due the constant call for heat resulting in appliance
being in a constant or over fire situation. Consequential damage from this type of operation will deem the
warranty null and void.
All Blaze King wood appliances are designed to burn cord wood only. Dimensional timber off cuts, very low
moisture content small diameter wood and pressed wood logs, when used in excess, may result in excessive
internal firebox temperatures that can cause causing irreversible damage to the firebox’s internal structure.
Excessive temperatures can be caused by many small pieces of very low moisture content wood being used
as a primary fuel source. This may be evident by warping or warped internal plates and retainers, possible
cracking of the outer firebox and possibly premature failure of the catalytic combustor. All wood appliances
should be cleaned out and inspected at the end of every burning season to identify if any internal components
have been affected during the burning season. If problems are observed steps must be taken to identify and
correct the problem before the subsequent burning season. Failure to do so will result in the warranty of the
product being null and void.
