HOW TO USE MOISTURE METERS
1. Take a random selection of around 3-4 logs per
cubic yard or cubic metre.
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 suffi
cient contact (see fi gure).
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
Effi
ciency 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 Effi
ciency (AFUE) attempts to represent the actual, season long, average effi
ciency of
an appliance. HHV is the actual, calculated average effi
ciency obtained under test conditions. Using correctly
seasoned wood is important when trying to gain effi
ciency. Th
e more seasoned (dry) the wood, the higher the
effi
ciency (less energy wasted on eliminating moisture during combustion). Operating your Blaze King at lower
settings will result in higher effi
ciencies as the fuel will undergo a more complete combustion. For maximum
effi
ciency, 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 .
