APPENDIX C: FLAME CARACTERISTICS

Efficient flame
An efficient flame should be bright but not too
vigorous. The flame should also have a yellow
to bright look. There should also be some small
embers or spark exiting the flame and burn pot.
The following picture #1 is the flame pattern
that will produce optimum efficiency.
Fire with too much air
A small blow torch flame as in image #2 is a
result of too much oxygen being supplied to the
fire. This causes the flame to be very short with
a bright yellow to almost white, flame look. This
pattern does not allow optimum heat transfer to
the heat exchanger
convection efficiency. Depending on the quality
of the pellets, there are usually more embers or
sparks exiting the flame and burn pot. To rectify
this condition, reduce combustion air flow to
obtain a flame pattern as in image #1.
Fire with not enough air
If the flame pattern is tall, lazy and orange with
black smoky tips as in image #3, it is generally
a result of insufficient air flow through the
system. The possible causes are either a lack
of oxygen to the fire, high moisture content
pellet, obstructed channel or vent. This situation
will lead to excessive black soot accumulation
on the baffle and the glass. To rectify this
condition, make sure the stove and the vent
system is clean, the pellet being used is dry and
increase combustion air flow if necessary.
