8.0 GENERAL OPERATING INSTRUCTIONS

8.1 OPERATION FOR HIGHER EFFICIENCY AND LOWER EMISSIONS
This appliance has been certifi ed to CSA B415.1-10 Emission Standards and is being reviewed for compliance
with Step 1.1 or Step 1.2 of the NSPS requirements.
The heat output ranges, effi ciencies, and particulate emission rates are as follows:
WOOD FURNACE:
Average Particulate Emnission Rate
Average Effi ciency, Delivered Heat
Delivered Heat Output Rate:
Average Effi ciency, Overall Heat Output
Overall Heat Output Rate:
The stated effi ciency is based on the higher heating value of the fuel.
Results may vary from the data in the tables above based on actual installation and operating parameters
encountered.
A basic operating parameter that can dramatically affect the performance of the furnace is the type and mois-
ture content of the wood used as fuel.
To get the maximum effi ciency and lowest emission performance from your furnace consider the following
points:
• The corner stone for running any wood fi red appliance is to only use split seasoned wood with low mois-
ture content. For best results split wood should be aged outdoors in a covered space for a period of at
least one year. When measured (with the moisture meter supplied with this furnace), the moisture content
of the wood should not exceed 18%.
• Split dimensions of the wood can also play and important part in the performance of this furnace. Opti-
mum performance of this furnace is obtained when running the fuel in full batches (loading the fi rebox with
a full fuel load and not replenishing until it has burnt down to a shallow coal bed). For fuel packing and
burn time purposes the ideal length of wood is one inch shorter than the length of the fi rebox and a pie
shaped cross section measuring 4" to 6" (10 cm to 15 cm) wide by 6" to 8" (15 cm x 20 cm) high.
• The energy released and overall heating capacity differs when burning hardwood or softwood. Hardwood
has a higher density than softwood and will give you more fuel by weight in the fi rebox. The energy con-
tent of the wood is also proportional to its weight, subsequently more energy is released by the hardwood.
• The draft created by the furnace/chimney installation is critical to the overall heat output effi ciency and
emissions created by the appliance. Note that the length of the chimney is not only dictated by the safety
requirements of the local installation codes but by its ability to provide the right draft for optimum furnace
performance. Without adequate draft the fi re created can be lazy creating excessive smoke and particu-
late and not develop the heat output required. Too much draft can result in excess heat being drawn out
the chimney instead of being released into the circulation air at the heat exchangers. In extreme cases too
much draft can lead to over fi ring of the furnace and potential damage to property and life. The operating
draft required for this appliance is between -0.04" to -0.06" water column.

SMOKE AND CARBON MONOXIDE EMISSIONS AND MONITORS

During the combustion process the presence of smoke is a strong indicator that the fuel is not being consumed
effi ciently. Smoke is created when the combustion air supply to the fuel load is inadequate to burn all the
gases and particulate being released as the wood is consumed. This is why it is important to establish the
correct draft with the furnace/chimney system. One of the bi-products of poor combustion is carbon monoxide.
