IMPORTANT: 

 The glass must be allowed to warm slowly 

and evenly.  The tempered glass will withstand a gradual 
temperature rise to 550 degrees Fahrenheit, which is more 
than a normal fire will generate.  Such materials as pitch/wax-
laden logs, very dry mill end lumber, and large amounts of 
paper or cardboard boxes can create an excessively hot fire 
and should not be burned in this fireplace.  Always keep the 
fire well back from the doors and never allow flames to 
contact the glass. 
 

WARNING:

  FIREPLACES EQUIPPED WITH GLASS 

DOORS SHOULD BE OPERATED ONLY WITH DOORS 
FULLY OPEN OR DOORS FULLY CLOSED.  DOORS, IF 
LEFT PARTLY OPEN, MAY DRAW GAS AND FLAME 
OUT OF THE FIREPLACE OPENING CREATING RISKS 
OF BOTH FIRE AND SMOKE. 
 

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 YOUR 
SUPPLIER OR 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 
distributor.  Use only a 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 20). 
 

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 rear at 11 – ¼ inches from the floor and through 
gas line conduit sleeve (if using a raised platform, add height).  
Provide sufficient gas line into fireplace chamber for fitting 
connection (see figure 21). 

 
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 gas appliance or cap-off gas line if desired.

 

 
 

 
NOTE:

  Secure incoming gas line to wood framing to provide 

rigidity for threaded end. 
 
 
 
 
 

 
 
 
 
 
 

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 10)

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.
