C. Wet wood
Wet or tarred wood will smoulder and smoke instead of burning properly.
D. Dirty or blocked chimney
Check to make sure the chimney is clear and clean.
E. Chimney not long enough
The minimum system height is 18 feet (5,5 m). The chimney must extend at least 3 feet (915
mm) above its point of contact with the roof and at least 2 feet (0.6 m) higher than any roof or
wall within 10 feet (3 m) of it. When installed with offsets, the minimum system height is as
per Table 2. 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 at the
bottom of the throat. Chimneys installed against an outside wall without protection may
generate back draft problems which will cause start-up problems. To prevent this, when you
light a fire make sure you use small pieces of really dry wood and keep your glass door
closed for the first 15 minutes. Reload your unit a few times with kindling before putting
large pieces of cordwood.
IMPORTANT NOTES
a. Do not burn coal. The sulphur in coal will corrode the firebox.
b. Do not allow the wood to smoulder or burn without flame, since this will produce
excessive creosote in the unit.
c. The exhaust damper and air intake control should be always in the open position when
the fireplace is in use.
2.3 Maintaining Your FP11 Frontenac Wood Fireplace
2.3.1 Creosote – Formation and Need for Removal
When wood is burned slowly without a flame, it produces tar and other organic vapours which
combined with expelled moisture will form creosote. The creosote vapours condense in the
relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on
the flue lining. When ignited this creosote makes an extremely hot fire. The chimney should be
inspected at least twice a year during the heating season to determine if creosote build-up has
occurred. When creosote has accumulated it must be removed to reduce the risk of a chimney
fire.
