DIRECT-VENT FIREPLACE (NATURAL/PROPANE/LP)

PRE-INSTALLATION PREPARATION

LOCATION AND SPACE REQUIREMENTS

Determine the safest and most efficient loca- tion for your Comfort Glow direct-vent fire- place. Make sure that rafters and wall studs are not in the way of the venting system. Choose a location where the heat output is not affected by drafts, air conditioning ducts, windows or doors. Figure 2 shows some common locations. Read all venting infor- mation in this manual. Be aware of all re- strictions and precautions before deciding the exact location for your fireplace.

When deciding the location of your fire- place, follow these rules:

1.Do not connect this fireplace to a chim- ney flue serving a separate solid-fuel burning fireplace or appliance.

2.Due to high temperatures, do not lo- cate this fireplace in high traffic areas or near furniture or draperies.

3.Proper clearances must be maintained.

4.If your fireplace is to be installed di- rectly on carpeting, vinyl tile, or any combustible material other than wood, it must be installed on a metal or wood panel extending the full width and depth of the fireplace. See Figure 3.
