Installing Damper Clamp
Remove all ashes or other debris from the fireplace. If the fireplace is equipped with an ash dump, be
sure to seal the door with furnace cement or high temperature silicone. Be sure to check the damper for
proper operation and verify that the flue passageway is open.
Place the clamp over the lip of the damper and tighten the hold down bolt until the clamp is securely
attached to the damper. This will prevent the damper from accidentally closing.
Chimney damper must be fixed in a manner which will maintain the minimum permanent vent opening at
all times. (Damper manufacture shall recommend means to accomplish this, such as by a screw or bolt in
the edge of the damper to prevent its closing or by a hole or holes in the damper).
Manual and millivolt controlled gas logs may be installed as a vented decorative log set in compliance
with ANSI Z21.60 and National Fuel Gas Code. When the gas logs are operated with the damper open,
non-combustible material and minimum mantel requirements do not apply.
Note:
When installing your log set as a vented installation the damper clamp (Not Provided in hardware)
must be used.
Floor Clearances:
1. If installing appliance on the floor, you must maintain the minimum distance of 14 inches to
combustibles (see Figure 9)
2. If combustible materials are less than 14 inches to the fireplace, you must install appliance at least
5 inches above the combustible flooring (See Figure 8)
