3.2.9 Smoking – Causes and Troubleshooting

To reduce the likelihood of smoking when opening the door, set the combustion air controls
to the left before opening the door.  Your fireplace 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 continue.  If the fireplace 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 chimney.  This air must be replaced through leakage
into the house or through the outside air duct.  When operating the BIS ULTIMA, open a
nearby window temporarily to check if there is adequate air supply replacement.

B. Fans operating (e.g.: range hood)

These fans draw air out of the house and may actually cause a negative pressure in the
house.  Turn off all fans 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 burn properly.

D. Dirty or blocked chimney

Check to make sure the chimney is clear and clean.

E. Chimney not long enough

The minimum chimney height is 12 ft. not including the fireplace height.  The chimney
must extend at least 3 feet (915 mm) above its point of contact with the roof and at least 2
feet (610 mm) higher than any roof or wall within 10 feet (3 m) of it.  When installed
with offsets, the minimum chimney height is 15 ft.  Additional height will increase
draught and will decrease the tendency to smoke.

F. Poor chimney draft

With no fire, there should be sufficient draught to exhaust cigarette smoke introduced
under the baffle.  Chimneys installed against an outside wall without protection may
generate back draught 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 draught is sufficient, then start
the fire.

G. Blower for central forced air kit operating

Make sure that the blower is at the "off" position when you open the fireplace door for
reloading.
