A gas line may be installed for the purpose of installing a 
vented or vent-free gas appliance available through your local 
distributor.  Use a ½” black iron pipe and appropriate fittings.  
When installing a gas line, a shut-off valve designed for 
installation outside the appliance is recommended. 
 
STEP 1: To install, remove the knockout indentation on the 
firebrick wall located approximately 2 inches above the 
refractory hearth floor on the required side.  The knockout 
indentation must be firmly tapped with any solid object until it 
is released.  Remove fragmented portions of refractory (see 
figure 7). 

 
STEP 2: Remove gas line cover plate on rear of fireplace and 
pull out insulation from gas line conduit sleeve.  Save 
insulation for reuse. 
 
STEP 3: Run a ½” (I.D.) black iron gas line into the fireplace 
through the gas line conduit sleeve (if using a raised platform, 
add height).  Provide sufficient gas line into fireplace chamber 
for fitting connection (see figure 8). 

 
NOTE: Secure incoming gas line to wood framing to provide 
rigidity for threaded end. 
 
STEP 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 the decorative gas appliance or cap-off gas 

line if desired.  Follow the manufacturer’s installation 
instructions provided with the gas appliance. 

 

VENT-FREE GAS LOG INSTALLATION: 

 
If you wish to 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 Z21.11.2, are to be 
installed in this fireplace. 
 

NOTE:

  A DESA hood must be installed when using an 

unvented gas log set (see accessories on page 11). 
 

 

VENTED GAS LOG INSTALLATION: 

 
If you install a decorative gas appliance (vented gas log), the 
decorative gas appliance must comply with the Standard for 
Decorative Gas Appliance for Installation in solid fuel burning 
fireplace, ANS Z21.60-1996, Z21.84 or RGA 2-72, and shall 
also be installed in accordance with the National Fuel Gas 
Code, ANS Z223.1-1996.  
 

 

COLD CLIMATE INSTALLATIONS: 
 

The following installation procedures are recommended when 
installing a fireplace system in a cold climate area.  Following 
these steps will aid in reducing cold air infiltration from the 
fireplace enclosure into living space. 
 
1.

 

The fireplace must be placed on a solid continuous 
surface.       You should insulate under the fireplace in all 
cold climate areas. 

2.

 

In the case of a raised platform or cantilevered chase, you 
should insulate under the structure to reduce air 
infiltration. 

3.

 

Insulate the walls of the chase, both on the outer and 
interior partitioning wall (see figure 9).  Clearances from 
pipe to insulating materials must be maintained. 

4.

 

Using a firestop spacer in the chase at the ceiling level is 
recommended for safety and reducing cold air movement 
(see accessories on page 11).

Figure 8       GAS LINE INSTALLATION 

 CAUTION:

All gas piping and connections must be 

tested for leaks after the installation is completed.  After 
ensuring that the gas valve is on, apply a 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.

 WARNING:

Do not operate an unvented gas log set in 

this fireplace with the chimney removed. 

 WARNING:

 When using a decorative gas appliance, 

the damper must be removed or permanently locked in the 
fully opened position.
