Flex Venting:
This fireplace is certified to work with aluminium co-
axial flex venting. Flex venting can be used in the same
configurations as rigid pipe, see venting diagram for
details. Flex venting is only to be used for the run, it must
be adapted to rigid piping for exterior wall penetration and
termination.
Note: Adhere to all rigid venting safety
measures and clearances.
Use 5X8 Flex Adapter Kit [50-3789]: This kit will allow
you to adapt co-axial flex to the fireplace, make your
vent run, then adapt back to rigid venting
(flex not
included) .
NOTES:
• Do not bend flex vent over 90 degrees.
• All horizontal runs should have a minimum 1/4”
(6mm) rise per foot for optimal performance.
• Do not allow the inner flex pipe to contact the outer
pipe, keep it pulled tight and use spacer springs.
• Spacers are required at the start, middle, and end of
each elbow to ensure gap is maintained.
• Do not add any extensions to the preset kits, if more
length is required, use rigid pipe.
• No need for liquid sealant; secure flex venting with
aluminum vent tape and apply sufficient self-tapping
screws.

A snorkel is permitted for use on installations where additional
vertical rise is required on the exterior of the building. Refer to the
table below for the approved models. Note, the use of a snorkel
does not reduce the minimum required venting or termination
clearances.
