1.2 CHIMNEY AND DRAFT
This furnace must be connected to a chimney certified for wood burning heating
appliances; a 6” connector and chimney is mandatory.
If the chimney draft exceeds -0.06’’ w.c, a barometric draft control should be
installed on the smoke pipe. Never install a manual damper.
The barometric control must be adjusted so that the maximum draft measured at
the furnace outlet does not exceed -0.06’’ w.c. Please note that a draft
exceeding -0.06” w.c. will reduce the efficiency and could produce an
uncontrollable fire.
On the other hand, the minimum draft required is 0.04”
w.c. in the evacuation pipe on the wood side, no matter what type of
furnace.
