Product Features

These are a few facts that can help you understand and enjoy your direct-vent fireplace:

The dedicated top vent for this fireplace is suited for any application where height is necessary to terminate the venting system either through the roof (vertical) or to gain sufficient height and offset to vent to an outside/exterior wall (horizontal).

The vent pipe installation is very important to allow for proper operation. You must select the appropriate vent kits and components for your application and follow the venting instructions to plan your installation.

This fireplace may be installed in any room pro- vided that all rules of the housing authority and these installation instructions are followed.

This fireplace is equipped with a millivolt gas control system that does not require electricity to operate. A piezo ignitor is provided to light the pilot without using matches or lighters.

This model can accept an optional circulating air blower when 120 VAC connection is sup- plied. If you plan to install an optional blower, do not forget to wire the fireplace outlet when framing.

Each time you turn on your fireplace, you may notice some amount of condensation on the in- side of the fireplace glass. This is normal and will disappear after 10-20 minutes of operation.

Your direct-vent gas fireplace system (fireplace and venting) is a balanced and sealed gas oper- ating unit. It is highly efficient because it uses outside air for combustion while independently heating the indoor air.

Pre-Installation

Preparation

Location and space requirements

Determine the safest and most efficient location for your DESA/Vexar 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 locations. Be aware of all restrictions and precautions before deciding the exact location for your fireplace and termination cap.

When deciding the location of your fireplace, follow these rules:

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

Due to high temperatures, do not locate this fireplace in high traffic areas, windy or drafty areas or near furniture or draperies.

Proper clearances must be maintained.

If your fireplace is to be installed directly 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, page 6.

Your fireplace is designed to be used in zero clearance installations. Wall or framing material can be placed directly against any exterior sur- face on the back, sides or top of your fireplace, except where standoff spacers are integrally attached. If standoff spacers are attached to your fireplace, these spacers can be placed directly against wall or framing material. See framing details on page 6.

If you plan on installing a television or enter- tainment center recessed above your fireplace, it is recommended that you maintain a minimum 18" above top of louver opening.
