WARNING: Do not operate an unvented gas log set in
this fireplace with the chimney removed.
WARNING: When using a decorative appliance, the
damper must be removed or permanently locked in
the fully open position.
GAS LINE
A gas line may be installed for the purpose of installing a decorative
gas appliance available through your local distributor. Use only 1/2"
black iron pipe and appropriate fittings. When installing a gas line,
a shut-off valve designed for installation outside the firebox is
recommended.
To install, remove the gas line plug located in the side firebrick
approximately 2" above the bottom, The plug must be tapped out
from the finished side towards the unfinished side (see Figure 11A).
WARNING: All gas piping and connections must be
tested for leaks after the installation is completed. Be
sure gas valve is turned on. Apply soap suds solution
to all connections and joints. If bubbles appear, leaks
must be detected and corrected. DO NOT use a match
or open flame of any kind to test leaks. Never operate
any appliance with leaky connections.
WARNING: Hearth extension is to be installed only as
illustrated.

TEST FOR GAS LEAKS
The gas pipe is intended for connection to an unvented gas log set or
to a decorative gas appliance.
If you will install an unvented gas log set, ONLY VENTED GAS LOG
SETS WHICH HAVE BEEN FOUND TO COMPLY WITH THE
STANDARD FOR UNVENTED ROOM HEATERS, ANS/IAS/AGA
Z21.11.2, ARE TO BE INSTALLED IN THIS FIREPLACE.
Note:
An appropriate Comfort Glow hood must be installed when
using an unvented gas log set.

HEARTH EXTENSION
A hearth extension projecting a minimum of 20" in front of and a
minimum of 12" beyond each side of the fireplace opening is
required to protect combustible floor construction in front of the
fireplace, Use a layer of noncombustible, inorganic material having
a thermal conductivity of K=0.64 BTU IN/FT. HR. F (or less) at 1"
thick. Example of determining hearth extension equivalent. If the
material selected has a K factor of 0.25, such as glass fiber, then the
following formula would apply: 0.25/0.64 X 1" = .39" thick. This
must be covered by a noncombustible material such as tile, slate,
brick, concrete, metal, glass, marble, stone, etc. Fasten the hearth
extension to the floor to prevent shifting and seal the gap between the
fireplace frame and hearth extension with a noncombustible material
(see Figure 12).
DAMPER OPERATION
The damper handle to open and close the damper blade is located inside
the firebox at the center towards the back wall. Pushing the handle back
into the keyway slot will free the damper blade to automatically open.
To close, reach in and push the handle back into the keyhole slot then pull
down and forward to lock it in place (see Figure 13).
