Chimney Routes
1)
This fireplace must be vented with a 8" (200mm)
diameter Class “B” vent. The installation of the venting
system must conform and be in accordance with the
natural gas installation code CAN/CGA - B149
(Canada), ANSI Z223.1 (U.S.A.), AG 601 (Australia),
and NZS 5261 (New Zealand). Minimum chimney
height from base of fireplace must be at least 12 feet
(3.7m).
INSTALLATION
2)
Masonry Chimney Installation:
This application can be connected to a masonry
chimney flue. Make sure the masonry chimney is
clean and in good working order. When an existing
masonry chimney is unlined and local experience
indicates that gas condensation may be a problem or
if local codes dictate, an approved liner should be
installed. Use “B” Vent to bridge the gap between the
fireplace and the masonry chimney. To ensure proper
flue sizing and operation it is recommended that the
masonry chimney be lined with an approved aluminium
chimney liner of the same diameter as the “B” Vent.
Make sure connection between “B” Vent and masonry
is completely sealed. Flue pipe exposed to cold air
should be insulated in a chase. If condensation
occurs, a trap should be installed at bottom of flue.
