Framing and Finishing

Check fireplace to make sure it is levelled and properly positioned.

1. Choose the unit location.

2. Place the unit into position and secure it to the floor with 1.5” (38 mm) screws, or nails. The holes to secure the unit to floor are located just behind the access door grille on the left and right side 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. Attach the fireplace to the frame using the adjustable frame drywall strips (located behind the access door for shipping). Preset the depth to suit the facing material of the wall. The strips are adjustable to 1/2” (13 mm), 5/8” (16 mm), or 3/4” (19 mm). (Fig. 5)

5. Screw through the slotted holes in the drywall strip and into predrilled holes in fireplace side. Measure from face of fireplace to the face of the drywall strip to confirm the final depth.

Final Finishing

Noncombustible materials such as brick or tile may be extended over the edges of the face of the appliance.

DO NOT cover the window frame assembly, any vent, louvre assembly top or louvre assembly bottom.

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.

Gas Line Installation

When purging the gas lines, the front glass must be removed.

The gas pipeline can be brought in through the side of the fireplace as well as the bottom. Knockouts are provided on the bottom behind the valve to allow for the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in from the rear right side 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 approved 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.

Always check for gas leaks with a mild soap and water solution applied with a brush no larger than 1” (25 mm). Never apply soap and water solution with a spray bottle. Do not use an open flame for leak testing.

Do not subject the fireplace valve to test pressures exceeding 1/2 p.s.i. Isolate, or disconnect this and any other gas appliance control from the gas line when pressure testing.

The gas control is equipped with a captured screw type pressure test point; therefore, it is not necessary to provide a 1/8" test point up stream of the control.

When using copper or flex connector use only approved fittings. Always provide a union when using black iron pipe so that the gas line can be easily disconnected for burner or fan servicing (Fig. 6). See the gas specification for pressure details and ratings.

10004920

Vermont Castings, Majestic Products: DVR33

Twist Lock Pipes

When using Vermont Castings, Majestic Products twist-lock pipe it is not necessary to use sealant on the joints. The only areas of the venting system that need to be sealed with high temperature silicone sealant are the collars on the fireplace and termination, and the sliding joint of any telescopic vent section used in the system.

To join twist lock pipes together, simply align the beads of the male end with the grooves of the female end, twisting the pipe until the flange on the female end contacts external flange on the male end. It is recommended that you secure the joints with three (3) sheet metal screws, however this is not mandatory with twist lock pipe (Fig. 14).

To make it easier to assemble the joints we suggest putting a lubricant (Vaseline or similar) on the male end of the twist lock pipe prior to assembly.

Locate and cut the vent opening in the wall. For combustible walls first frame in opening (Fig. 16). Combustible Walls: Cut a 10³⁄₈”H x 9³⁄₈” W (265 mm

x 240 mm) hole through the exterior wall and frame as shown.

Noncombustible Walls: Hole opening should be 7¹⁄₂” (190 mm) in diameter.

Zero clearance sleeve is only required for combustible walls.

Step 2

Measure wall thickness, and cut zero clearance sleeve to proper length; i.e., max. 12” (304.8 mm). Assemble sleeve to its maximum opening (10

⁄

” x 9

⁄

”) and attach to firestop with #8 sheet metal screws (supplied). Install firestop assembly (Fig. 17).

Step 3

Measure the horizontal length requirement for the venting including a 2” (50 mm) overlap, i.e. from the elbow to the outside wall face plus 2” (50 mm) (Fig. 15).
