FIREPLACE ENCLOSURE: COLD CLIMATE
INSTALLATIONS
Before finishing the enclosure around the fireplace, inspect all joints
around the fireplace. Any gaps between the nailing flanges and the
framing should be sealed with noncombustible insulation or caulk-
ing (see Figure 12). Inspect the fireplace joints for possible gaps
caused by shipping or mishandling during installation. These should
be sealed with noncombustible materials. If the fireplace is mounted
on a raised platform, insulate below the platform to prevent the entry
of cold air through the fireplace bottom by means of conduction. The
above steps are important, especially if the fireplace is installed in
cold weather climate. The opening around the base of the chimney
must remain open and free to circulate outside air for keeping the
chimney cool as designed (see Figure 4, page 3). The fireplace must
be set on a continuous platform to prevent cold air from conducting
through the metal bottom. The platform bottom may be constructed
of any wood product or other materials such as cement.

GAS LINE
A gas line may be installed for the purpose of installing a 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 fireplace 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 13).

TEST FOR GAS LEAKS
WARNING: All gas piping and connections must be
tested for leaks after the installation is completed. Be
sure gas valve is turned on. Apply soapsuds 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 for leaks. Never
operate any appliance with leaky connections.
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 UNVENTED 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 Vanguard hood must be installed when
using an unvented gas log set (see page 10).
WARNING: DO NOT OPERATE AN UNVENTED GAS
LOG SET IN THIS FIREPLACE WITH THE CHIMNEY
REMOVED.
If you will install a decorative gas appliance, the decorative gas
appliance must comply with the Standard for Decorative Gas
Appliances for Installation in solid Fuel burning Fireplaces,
ANS Z21.60-1996 and shall also be installed in accordance with the
National Fuel Gas code, ANS Z223.1-1996.
WARNING: WHEN USING A DECORATIVE APPLIANCE,
THE DAMPER MUST BE REMOVED OR PERMANENTLY
LOCKED IN THE FULLY OPEN POSITION.
