CHECK GAS TYPE
Use only natural gas. If your gas supply is not
natural gas, you must install ON/OFF Safety
Valve/Pilot Kit (see Accessories, page 18). Call
dealer where you bought log set.
If the fireplace does not have a gas supply shutoff
valve, one must be installed.
VENTING SPECIFICATIONS FOR
INSTALLATION
The fireplace chimney flue and vent must be draft-
ing properly. To check the vent for proper drafting:
Light a tightly rolled newspaper on one end and
place it at the inside front edge of the fireplace.
Observe the smoke and be sure the vent is properly
drawing it up the chimney. If the smoke spills out
into the room, extinguish the flame and remove any
obstruction until proper venting is achieved.
The chimney flue must remain open a minimum
of 3" at all times during the operation of this
log set.
INSTALLING DAMPER CLAMP
Secure the damper stop clamp provided to the
leading edge of the damper as shown in Figure 3.
If for any reason this clamp doesn't work on your
fireplace, another suitable clamp or permanent
stop must be installed, or the damper blade must
be cut or removed.

WARNING: A qualified ser-
vice person must connect log
set to gas supply. Follow all
local codes.
