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. Follow instructions below to install

fireplace in this manner.
Note:

The instructions below show installation us-

ing the cabinet mantel and hearth base accessories

(see Accessories, page 36). The hearth base acces-

sory shown is optional for this installation. You

can install fireplace and cabinet mantel directly

on the floor. The corner mantel accessory cannot

be installed with the hearth bases. You must install

corner mantel directly on the floor.
1. Assemble cabinet mantel, hearth base and

trim accessories. Assembly instructions are

included with each accessory.

2. When installing blower, 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. If not already completed, install gas piping to

fireplace location. This installation includes an

approved flexible gas line (if allowed by local

codes) after the equipment shutoff valve. The

flexible gas line must be the last item installed

on the gas piping. See Installing Gas Piping

to Fireplace Location, page 13.
