NOTE: If the stove has been brought in from a cold environment (an unheated
warehouse), the reading you get may be lower than normal. This is due to the High
Temp Lubrication used in the Combustion fan not allowing the fan to spin as easily
as a fan at room temperature.

Factors that Decrease the Draft Readings
a) Altitude**
b) The following factors are in addition to installation procedure:
c) Increasing the exhaust pipe vertical length without increasing exhaust pipe diameter
when required for installation. **
d) Increasing the horizontal exhaust pipe length. **
e) Increasing the number of tees and elbows: the exhaust vent piping will, for most
applications, have two (2) 90-degree bends. More than three (3) bends in the exhaust
vent is NOT RECOMMENDED.
f) Increasing the air inlet pipe length recommended for installation without increasing
the diameter of the pipe. It is recommended to increase the air inlet pipe to 3"
diameter for runs over ten (10) feet and at elevation over 4000'. Excessive runs (12 to
15 feet+) should be avoided.
