CLEANING THE GLASS: 

Clean the glass with any 

commercial glass cleaner or soap and water.  DO NOT 
use any abrasive material to clean the glass.  DO NOT 
clean the glass with any cool water if the glass is still hot 
from the fire.  
 

FOR PERMANENTLY LOCATED (SITED) HOMES 
ONLY: OPTIONAL GAS LINE INSTALLATION 

 
GAS LINE HOOK UP SHOULD BE DONE BY A 
QUALIFIED SERVICE PERSON. 

NOTE:

  BEFORE YOU PROCEED, MAKE SURE YOUR 

GAS SUPPLY IS TURNED OFF. 
 
A gas line may be installed for the purpose of installing a 
vented or vent-free gas appliance available through your local 
dealer.  Use only ½ inch 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 

refractory, (or firebrick), wall located approximately 2 inches 
above the refractory hearth floor.  The knockout indentation 
must be firmly tapped with any solid object until it is released.  
Remove fragmented portions of refractory (see figure 19). 
 

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 inch black iron gas line into the fireplace 

through the gas line conduit sleeve.  Provide sufficient gas line 
into fireplace chamber for fitting connection (see figure 20). 

 
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. 
 

The gas pipe is intended for connection to an unvented (vent-
free) or a decorative gas appliance (vented gas log). 
 
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. 
 
A vent-free log may be installed in an aftermarket,

  *

 

permanently located, manufactured (mobile) home, where not 
prohibited by local codes. 

*

Aftermarket: Completion of sale, not for purpose of resale, 

from the manufacturer. 
 

NOTE: A DESA hood must be installed when using an 
unvented gas log set 

(see accessories on page 11)

 
 
 
 
 
 

If you install a decorative gas appliance (vented gas log), the 
decorative gas appliance must comply with the 

Standard for 

Decorative Gas Appliances for Installation in solid fuel 
burning Fireplaces, 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.

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 commercial leak detection 
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 

VENTED GAS LOG, THE DAMPER MUST BE 
REMOVED OR PERMANENTLY LOCKED IN THE 
FULLY OPENED POSITION. 

WARNING:

If the fireplace has been used for wood 

burning, the firebox and chimney must be cleaned of 
soot, creosote and ashes by a qualified chimney cleaner. 
Creosote will ignite if highly heated.
