ing an automatic shutoff device and complying with the Standard
for Decorative Gas Appliances for Installation in Vented Fireplaces,
ANSI Z21.60 or American Gas Association draft requirements for
Gas Fired Log Lighters for Wood Burning Fireplaces, Draft NO. 4
dated August, 1993.
If you wish to install an unvented (vent-free) gas log set, only
unvented gas log sets which have been found to comply with the
standard for unvented room heaters, ANSI Z21.11.2 are to be installed
in this fireplace.
Gas line hook up should be done by your supplier or a qualified
service person.

Before you proceed, make sure your gas supply is turned off.
Use only a 1/2" black iron pipe and appropriate fittings.
1. Remove knockout indentation on refractory or firebrick wall

be firmly tapped with any solid object, such as a 1/2" dowel, until
it is released. Remove fragmented portions of refractory (see
Figure 22, page 14).
2. Remove gas line cover plate located on either side of fireplace and
pull out insulation from gas line conduit sleeve. Save insulation
for reuse.

Figure 21 - Typical Residential Installations
Provide sufficient gas line into fireplace chamber for fitting
connection (see Figure 23, page 14).
Note:
Secure incoming gas line to wood framing to provide rigidity
for threaded end.
4. Repack insulation around gas line and into sleeve opening. Seal
any gaps between gas line and refractory knockout hole with
refractory cement or commercial furnace cement. Install gas
appliance or cap off gas line if desired.
CAUTION: All gas piping and connections must be
tested for leaks after installation is completed. After
ensuring that gas valve is on, apply soap and water
solution to all connections and joints. Bubbles forming
show a leak. Correct all leaks at once. DO NOT USE
AN OPEN FLAME FOR LEAK TESTING AND DO NOT
OPERATE ANY APPLIANCE IF A LEAK IS DETECTED.
LEAK TESTING SHOULD BE DONE BY A QUALIFIED
SERVICE PERSON.
Note:
An IHP hood must be installed when using an unvented gas
log set (see Accessories on page 19).
WARNING: Do not operate an unvented gas log
set in this fireplace with chimney removed.
