VENTING (FLUEING)
Note: The draft hood must be installed parallel to the
fireplace opening, as shown below. See Instruc-
tions in U31/I31 Installation Manual.
Install stove insert as per U31/I31 Installation Manual.
1) This fireplace must be vented (flued) with a 4" (100mm)
diameter Class “B” vent (Australia/New Zealand: twin
skin flue). The installation of the venting (flueing) system
must conform and be in accordance with the natural gas
installationcodeCAN/CGA-B149(Canada),ANSIZ223.1
(U.S.A.), AG 601 (Australia), and NZS 5261 (New Zea-
land). Minimum chimney height from base of fireplace
must be at least 12 feet (3.6m).
2) MasonryChimneyInstallation:
This application can be connected to a masonry chimney
flue. Makesurethe masonrychimneyis cleanandin good
working order. When an existing masonry chimney is
unlined and local experience indicates that gas conden-
sation may be a problem or if local codes dictate, an
approved liner should be installed. Use “B” Vent (flue) 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 (flue). Make sure connection between “B”
Vent (flue) 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.
Use a maximum of two off-
sets; four 45oelbows, or two
90oelbowsforexample. Slope
horizontal pipe at least 1/4"
(6.4 mm) rise per foot of run.
Horizontal runs should not
exceed the vertical rise. Keep
horizontal runs to a minimum.
See chart below.
NOTE: ColdClimateInstallation
When this appliance is to be in-
stalled against a non-insulated
wall or in a chase, fibreglass insu-
lation should be installed around
the body of the fireplace.
