Smoking – Causes And Troubleshooting
To reduce the likelihood of smoking when
opening the door, open the combustion
air control or damper before opening the
door. Your appliance has been designed
and tested to provide smoke free operation.
Occasionally, there may be a small amount
of smoking upon lighting the fire, until the
chimney heats up but this should not con-
tinue. If the appliance continues to smoke it
is probably for one of the following reasons:
A. Negative pressure in the house -
As the fire burns, air goes up the chim-
ney. This air must be replaced through
leakage into the house or through the
outside air duct. When operating the
appliance, open a nearby window tem-
porarily to check if there is adequate
replacement air supply.
B. Blowers operating (e.g.: range hood)
- These blowers draw air out of the
house and may actually cause a neg-
ative pressure in the house. Turn off
all blowers and open a nearby window
to determine if this is the cause of the
problem.
C. Wet wood - Wet or tarred wood will
smoulder and smoke instead of burning
properly. Your dealer can help you de-
termine if you have properly seasoned
wood for burning.
D. Dirty or blocked chimney - Check to
make sure the chimney is clear and
clean. If dirty call a certified chimney
sweep or use a properly sized chimney
brush to clean.
E. Chimney not long enough - The min-
imum chimney height is twelve (12)
feet (3.7 m) not including the appliance
height. The chimney must extend at
least three (3) feet (915 mm) above its
point of contact with the roof and at least
two (2) feet (610 mm) higher than any
roof or wall within ten (10) feet (3 m)
of it. When installed with offsets, the
minimum chimney height is fifteen (15)
feet. Additional height will increase draft
and will decrease the tendency to smoke.
F. Poor chimney draft - With no fire, there
should be sufficient draft to exhaust
cigarette smoke introduced under the
baffle or flue baffle. Chimneys installed
against an outside wall without protection
may generate back draft problems which
will cause start-up problems. To prevent
this, open a nearby window, roll up a
piece of paper and light it. Then, hold it
in the upper part of the firebox to warm
up the chimney. Wait until the draft is
sufficient, then start the fire.
G. Blower for forced air kit operating
(some models) - Make sure that the
blower is in the “off” position when you
open the appliance door for reloading.
Locating The Appliance
The best location to install your appliance
is determined by considering the location
of windows, doors, and the traffic flow in
the room where the appliance is located,
allowing space in front of the unit for the
hearth extension and the mantel, and taking
into consideration the location of the hot
air ducts (some models), outside air kit
and chimney.
If possible, you should choose a location
where the chimney will pass through the
house without cutting floor or roof joists.
When selecting the location, the chimney
outlet position and the direction of the wind
are important factor affecting the chimney
performance. To allow a maximum draft
and to reduce wind turbulence, the chim-
ney must:
• Penetrate the highest part of the roof.
• Be installed as far as possible of roof
offsets, trees or any other obstructions
that may cause wind turbulence and back
drafts in the chimney.
• The least amount of offsets (elbows)
possible. NOTE: A maximum of 2 offsets
is allowed.
