DIRECT-VENT FIREPLACE (NATURAL/PROPANE/LP)

PRE-INSTALLATION PREPARATION

CLEARANCES

Minimum clearances to combustibles for the fireplace are as follows:

Must maintain a minimum 1" clearance to combustibles

LOCATION AND SPACE REQUIREMENTS

Determine the safest and most efficient loca- tion for your Vanguard direct-vent fireplace. 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 loca- tions. Read all venting information in this manual. Be aware of all restrictions and precautions before deciding the exact loca- tion 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.

FRAMING AND FINISHING

Figures 4 and 5 show typical framing of this fireplace. Figure 6 on page 5 shows framing for corner installation. All minimum clear- ances must be met. Do not install fireplace directly on carpeting, vinyl tile, or any com- bustible material other than wood. The fire- place must set on a metal or wood panel extending the full width and depth of the fireplace.

See Accessories on pages 38 and 39 for mantel kits available for this fireplace. If you are using a separate combustible mantel piece, refer to Figure 7 on page 5 for proper installation height. You can install noncom- bustible mantels at any height above the fireplace.
