Not enough kindling/paper or no
kindling/paper
Use dry kindling, more paper. Arrange
kindling & wood for air movement.

Pre-warm flue before starting fire.

Use dry, seasoned wood (refer to

Bed of coals not established before
adding wood
Start with paper & kindling to establish
bed of coals (refer to Wood Burning
Operation).
Flue blockage such as birds’ nests or
leaves in termination cap
Have chimney inspected for creosote
and cleaned by a certified chimney
sweep.
Down draft or negative pressure
Competition with exhaust devices
Do not use exhaust fans during start-up
(refer to Negative Pressure Section).
Fire burns too fast
Extremely dry or soft wood
Mix in hardwood.
Mix in larger pieces of wood after fire is
established.
Overdrafting
Check for correct vent height; too much
vertical height creates overdrafting.
Check location of vent termination
(refer to Chimney Termination
Requirement Section in Installation
Manual).
Low Heat Output
Coal Bed too small
Open damper. Establish deeper coal
bed and move coals to the rear of the
firebox.

Operating on high for extended periods Reduce burn rate and allow coals to
burn down before reloading.
