INSTALLING FIREBOX USING
OPTIONAL ACCESSORY
MANTELS
NOTICE: A qualified service per-
son must install firebox. Follow
all local codes.
This firebox may be installed using a cabi-
net mantel accessory against a wall in your
home. The firebox and cabinet mantel can
be installed directly on the floor. A brass
trim kit is included with the mantel acces-
sory GM103U or GM105U (see Accesso-
ries, page 13).
1. Assemble cabinet mantel accessory and
the brass trim kit. Assembly instruc-
tions are included with each accessory.
2. If using an optional GA3700 Blower
(circulating models only), install a
properly grounded, 120 volt three-
prong electrical outlet at firebox loca-
tion if an outlet is not there. If possible,
locate outlet so cabinet mantel will
cover it when installed (see Figure 10).
3. Install gas piping to firebox location.
See Installing Gas Line, page 10. You
may have to cut an access hole in the
floor or wall to run gas line to firebox.
Make sure to locate access hole so cabi-
net mantel will cover it when installed
(see Figure 10).
