360 DVS Series Direct Vent Fireplaces

Hearth

A hearth is not mandatory; however, for aesthetic purposes, we recommend installing a noncombustible hearth that projects out 12” (305mm) or more from the front of the fireplace.

Cold climate installation recommendation:

When installing this unit against a noninsu- lated exterior wall or chase, it is mandatory the outer walls be insulated to conform to applicable insulation codes.

Framing & Finishing

1.Choose the unit location.

2.Place the unit into position and secure it to the floor with 1¹⁄₂” (38mm) screws or nails. Holes to secure the unit to the floor are located behind the access door grille on the left and right sides of the unit.

3.Frame in the fireplace with a header across the top. It is important to allow for the finished wall face when setting the depth of the frame.

4.Drywall (sheetrock) or wood material may be placed with a zero clearance to the top edges of the appli- ance when finishing walls above sides of the appli- ance with glass windows. NOTE: Attach wall finish- ing to constructed frame, not the appliance.

5.On 360DVSL and 360DVSR, drywall, wood, or wood molding may be placed with zero clearance to the rear wall of the unit, along the vertical edge formed by the standoffs, to intersection of the rear wall, to the side wall having the small glass window. NOTE:

Attach wall finishing to constructed frame, not the appliance.

Final Finishing

Noncombustible materials such as brick or tile may be extended over the edges of the face of the appliance. DO NOT cover any vent or grille panels.

If a Trim Kit is going to be installed on the fireplace, the brick or tile will have to be installed flush with the edges of the appliance.

Input ratings are shown in BTU per hour and are certified without deration for elevations up to 4,500 feet (1,370 m) above sea level.

For elevations above 4,500 feet (1,370 m) in USA, installations must be in accordance with the current ANSI Z223.1/NFPA 54 and/or local codes having jurisdiction.

In Canada, please consult provincial and/or local authorities having jurisdiction for installations above 4,500 feet (1,370 m).

Gas Line Installation

When purging the gas lines, the window frame assembly must be removed.

The gas pipeline can be brought in through the vent end of the fireplace as well as the bottom. Knockouts (to allow gas pipe installation and testing any gas con- nection) are provided on the bottom behind the valve. It is most convenient to bring the gas line in from the vent end of the valve, as this allows fan installation or removal without disconnecting the gas line.

The gas line connection can be made with properly tinned 3/8” copper tubing, 3/8” rigid pipe, or an ap- proved flex connector. Since some municipalities have additional local codes, it is always best to consult your local authority and the CSA-B149.1 installation codes.

For USA installations, consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

Always check for gas leaks with a mild soap and water solution. Do not use an open flame for leak testing.

The gas control is equipped with a captured-screw type pressure test point, therefore it is not necessary to pro- vide a 1/8” test point upstream of the control.
