Fumes
Flue joints leaking
Seal flue joints with recommended
flue sealer. Clean off any creosote
using warm soapy water and
abrasive cleaning pad.
Blocked Flue
Have flue professionally cleaned.
Insufficient draw from flue
Increase flue height to a minimum of
600mm above the ridge. Extend
flue height if adjacent to nearby tall
buildings or trees.
Fit H-type weather cap if all the
above does not remedy the
situation.
“Blow Back”
This happens if too much fuel is
added and smothers the bed of
embers. Gases are building up
before a flame eventually appears
and the gases suddenly ignite. The
result is a short, sharp blast of
smoke from the heater
Add smaller amounts of fuel until
desired fire is reached. Do not
smother the embers.
Ensure there is always a flame
present at all times. (The flame will
eliminate any sudden ignition of
gases).
Soot or creosote fire
Build up of soot or creosote in flue
Turn heater controls to off.
