The Optima 40-SB
Requires two flexible
gas flue liners:
Flue Collar (inlet)
3” (76 mm) diameter
Flue Collar (outlet)
3” (76 mm) diameter
Caution: Only two 3” (76 mm) “FLEX-MASTER” Model GA gas flex vent liners (or approved equivalent)
and a vent terminal is approved for use with this appliance.
Approved vent terminals are:
Archgard terminal. Part # 999-INS-TK.

NO OTHER VENTING SYSTEM OR COMPONENTS MAY BE USED. If you are using DuraVent vertical
termination cap, follow the instructions provided with the DuraVent cap.
This appliance is designed to attach to two 3” (76 mm) co-linear aluminum flex gas liners running the full
length of the chimney. The flue length must be a minimum of 8’ (2.44 M) and a maximum of 35’ (10.6 M)
The minimum flue size is 4” x 7” (100 mm X 178 mm). Masonry chimneys may take various contours
which the flexible liner will accommodate, however, keep the flexible liner as straight as possible, avoiding
unnecessary bending but at all times keep a minimum of 3” (76 mm) inside bend radius.
The Air Intake Flex Liner must be connected to the inlet air collars of the termination cap and the appli-
ance. The Exhaust Flex Liner must be connected to the exhaust collars of the termination cap and the
appliance. (DO NOT MIX UP THESE CONNECTIONS).
The Air intake and Exhaust connections are marked on the gas appliance. See Fig. 1.
CAUTION: To ensure that the venting path is not accidentally obstructed, or punctured the
damper of the host fireplace must be permanently disabled. By either complete removal of the
damper or welding it in it’s “open” position. Temporarily disabling the damper with braces,
wedges, brackets, ext,. Is not allowed.
