Initial Installation
QUALIFIED INSTALLERS ONLY
If using the the smaller 5” x 8” vent size on this appliance refer to Figure 54 below. Note there is a taller
minimum vent rise required as compared to what 8” x 11” venting requires. For safe and proper operation of
the appliance follow the venting instructions exactly. Deviation from the minimum vertical length will create
difficulty in burner start-up, flame appearance and sooting. Allow up to 15-20 minutes for the flame to mature
and colour after ignition when using this vent size. It is recommended for vent lengths that pass through
unheated spaces (garages, attics, crawl spaces) be insulated to minimize condensation.
NOTE: At least 3” (76mm) of clearance is required above vent when passing through an exterior wall when
horizontally terminating.
*IMPORTANT
- When using 5” x 8” venting the
CSS MUST BE ACTIVATED prior to installation. Use of
5x8 venting is NOT PERMITTED
without the CSS activated.*
