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 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 (if using a raised platform,
add height). Provide sufficient gas line into fireplace chamber
for fitting connection (see figure 20).
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.
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 teste
d
for leaks after the installation is completed. After ensuring
that the gas valve is on, apply a commercial leak detectio
n
solution to all connections and joints. Bubbles forming
show a leak. Correct all leaks at once. DO NOT USE AN
OPEN FLAME FOR LEAK TESTI
N
G AND DO NOT
OPERATE ANY APPLIANCE IF A LEAK IS
DETECTED. LEAK TESTING SHOULD BE DONE BY
A QUALIFIED SERVICE PERSON.
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
b
urning, the firebox and chimney must be cleaned o
f
soot, creosote and ashes by a qualified chimney cleaner.
