A combustion blower is used to extract the combustion gases from the
firebox. This causes a negative pressure in the firebox and a positive
pressure in the venting system. The longer the vent pipe and more
elbows used in the system, the greater the flow resistance. Because of
these facts we recommend using as few elbows as possible and 20 feet
or less of vent pipe. The maximum horizontal run should not exceed 3
feet and must have a slope of not less than 3%. The vertical distance
between one 90' elbow or T connector and another must not be less
than 4 ½'. If more than 20 feet of pipe is needed, the diameter should
be increased from 3" to 4" because a larger pipe causes less flow
resistance.
Using a draft gauge check that there is a minimum draft of 10 Pa when
the stove is burning at max level.
IMPORTANT! All sections of the venting must be
inspectable

must be done annually.
FOR CONNECTION TO THE FLUE PIPE, NOT MORE
THAN 3' OF HORIZONTAL AND NOT MORE THAN
THREE 90° ELBOWS ARE ALLOWED
IT IS ALSO ADVISABLE TO USE 4" PELLET VENT FOR
RUNS OVER 20' IN HEIGHT.
This type of connection ensures the ventilation of the
exhaust fumes in the event of a temporary power
outage.
Position the stove bearing in mind all the instructions and
considerations above.
