Chimneys taller than 20’ above the connection will re-

quire a draft test to determine if the draft is too high.

Note: The High Burn Draft should not exceed  .85

IWC. Some form of a restrictor plate may be required at the
top of high chimneys to reduce the draft. See page 19 for
the Draft Test procedure.

Creosote - Formation and Need for Removal - When wood is burned slowly, it produces tar and other organic vapors,
which combine with expelled moisture to form creosote. The creosote vapors 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 pellet vent pipe should be inspected at least twice monthly during the heating season to determine
if a creosote buildup has occurred. If creosote has accumulated it should be removed to reduce the risk of a chimney fire.

Guidance on minimizing creosote formation and the need for periodic creosote removal: The chimney should be

inspected during the heating season to determine if a creosote build-up has occurred. If a significant layer of creosote has
accumulated (3mm or more) it should be removed to reduce the risk of a chimney fire.

The PB105 Boiler may be used and installed into an

existing masonary or Class A metal chimney.
Certain Canadian and Local Codes may require that
the chimney be fully relined.

It Can Not be installed in a chimney serving another

appliance.

The chimney should be cleaned and or inspected be-

fore installation.
