Solution
Use dry kindling, more paper. Arrange kindling &
wood for air movement.
Open damper.
Check for restricted cap/shroud.
Check for flue blockage.
Pre-warm flue before starting fire (refer to starting
fire section).
Check for adequate vent height (refer to chimney
assembly section).
Open window below the fireplace towards the
wind.
Use dry, seasoned wood (refer to wood fuel
section).
Start with paper & kindling to establish bed of
coals (refer to starting fire section).
Have chimney inspected for creosote and cleaned
by a certified chimney sweep.
Do not use exhaust fans during start-up (refer to
negative pressure section).
Open window below the fireplace towards the
wind.
Mix in hardwood.
Mix in less seasoned wood after fire is established
(refer to wood fuel section).
Check for correct vent height; too much vertical
height creates overdrafting.
Check location of vent termination (refer to
chimney assembly section).
