Any accumulation of soot or debris in chimney
offsets should be removed
Any obstructions such as a protruding joint or a
piece of broken tile wedged in the chimney should
be removed.
No other appliance connection should be made to
the same fl ue pipe.
The fl ue pipe should have an upward pitch toward
the chimney of at least 1/4” per foot of length. It
should fi t tightly and should not project into the
chimney.
Any leakage between tiles, around clean-out doors,
or around the vent pipe should be sealed.

The new designs of high effi ciency oil furnaces and
boilers in conjunction with fl ame retention oil burners
are more effi cient. One result of increased effi ciency is
lower fl ue gas temperatures. As fl ue gases rise in the
chimney, they will cool and condense when they reach
the dew point. The condensation will mix with the sulphur
in the fl ue gases creating sulphuric acid. The acid will
attack the chimney mortar, brick and clay liners causing
corrosion, deterioration and blockage of the chimney.

Section: Inspect/Prepare Installation Site
Carefully inspect the chimney or exhaust vent
system.
Make sure it is properly sized and in good working
condition.
Follow the instructions supplied by the appliance
manufacturer.
The installation must strictly comply with all
applicable codes, authorities having jurisdiction and
the latest revision of the National Fire Protection
Association Standard NFPA 31 for the installation of
chimneys and vent sizing, (or CSA-B139 and CSA-
B140 in Canada).
Regulation by these authorities take precedence
over the general instructions provided in this
installation manual.
