CONVENTIONAL FIREPLACE
INSTALLATION
Conventional installation of fireplace involves in-
stalling fireplace along with corner, face or cabinet
mantel with hearth base accessories against a wall
in your home.
Note:
Refer to instructions provided with the man-
tel for assembly instructions. Refer to the follow-
ing instructions for system installation. Refer to
instructions on page 23 for hood assembly. Blower
accessory should be installed prior to mantel if it is
being used (see Installing Variable Speed Blower
Accessory, page 13, or Installing Thermostatic
Blower Accessory, page 15).
1. Assemble cabinet mantel as shown in acces-
sory instruction sheet.
2. If blower is installed, install a properly
grounded, 120 volt three-prong electrical out-
let at fireplace location if an outlet is not there.
If possible, locate outlet so cabinet mantel will
cover it when installed (see Figure 20).
3. Place hearth base against wall at installation
location. Cut an access hole in hearth base to
run gas line to fireplace (see Figure 20). Make
sure to locate access hole so cabinet mantel will
cover it when installed. Note: You can secure
base to floor using wood screws. Countersink
screw heads and putty over.
4. Route flexible gas line through access hole in
hearth base.
