Figure 19: Slider/Damper Plate & Rod in Unit.
This unit is designed to operate within a negative pressure range
of
0.15-0.17 inches of water column (37-42 Pa). (See
image on right for location to measure negative pressure
test port).
This can be measured using a Magnahelic pressure
gauge once the unit has been running on heat level 5 setting after
one hour of burn time. This adjustment is necessary for varying
venting configurations. The reading can be taken from the
⅛
” hole located on the right side of the Ash Box.
The Combustion Trim, Feed Trim and Fuel Type Functions can be used to compensate for varying fuel qualities. Refer
to the Owners Manual for circuit board operation.
If, after long periods of burning, the fire builds up or there is a build up of clinkers, this would be a sign that the fuel
quality is poor - this requires more air.
The easiest way to make sure that an efficient flame is achieved is to understand the characteristics of the fire.
• A tall, lazy flame with dark orange tips requires more air.
• A short, brisk flame, like a blowtorch, has too much air .
• If the flame is in the middle of these two characteristics with a bright yellow/orange, active flame with no black tips
then the air is set for proper operation, refer to Figure 20.
SPECIAL NOTES:
Fuel quality is a major factor in how the stove will operate. If the fuel has a high moisture content or ash content the
fire will be less efficient and has a higher possibility of the fire building up and creating clinkers (hard ash build-up).
