C. Existing Masonry Chimney Installation
This installation is subject to local jurisdic-
tion. Some codes may require the use of
another liner for intake air. If so, the 4"
aluminum liner should be inside a 6" UL 181
listed liner.
This Heater can be vented through an existing
Masonry Chimney but the chimney must be lined
with one UL 1777 listed 4" aluminum flexible gas
vent liner for exhaust. The existing Flue will be
used to supply the air intake to the galvanized
steel Flue system. See Figure 11.
