OPERATING INSTRUCTIONS
HOW TO USE MOISTURE METERS
1. Take a random selection of around 3-4 logs per
cubic yard or cubic meter.
2. Split each log down the middle.
3. In the center of log push pins of meter along
grain - three measurements are taken on the
freshly split surface: 2” or 5 cm in from each
end of the log and in the middle of the split
surface with sufficient contact (see figure).
4. Do this to all the logs and take an average of
the readings (this will be only an approximate
indication but a good guide).

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, does 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. For maximum
efficiency, the appliance should be installed in a location that provides adequate intake/combustion air as well
as a location that will allow for the straightest run of optimal chimney length to establish necessary draft .
