Figure 53: Minimum Vent - 8x11
This appliance uses either an 8” x 11” or 5” x 8” vent pipe system. For safe and proper operation of the
appliance follow the venting instructions exactly. Deviation from the minimum vertical length can create
difficulty in burner start-up, flame appearance and sooting. Allow several minutes for the flame to stabilize
after ignition under extreme vent configurations. 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.
