Note: The lower cover panel must be pushed all the way down. The outer finishing flanges should line up. The fireplace opening must be between 15-3/4 in. (400 mm) and 16-1/8 in. (410 mm) for the decorative fronts to fit correctly. See Figure 13.4.

Finish and Sealing Joints

All joints between the finished wall sheating and the appliance must be sealed with non-combustible materials. Sealants, such as caulk or mastic used to seal the gap between the wall and the fireplace, should be rated at a minimum continuous exposure to 149 °C (300 °F). Wall board joints can be taped and sealed with combustible drywall tape.

Finishing Around Opening with Gypsum Wallboard

Gypsum wallboard (drywall) joints adjacent to the fireplace opening require special attention to minimize potential development of cracking. Hearth and Home Technologies recommends the following steps to minimize potential cracks in the finished drywall around the fireplace opening:

When installing gypsum wallboard around the fireplace, install the hole for the fireplace opening in a single wallboard sheet, if possible. This will minimize the joints adjacent to the fireplace opening.

The factory-supplied non-combustible board and the gypsum wallboard must join on the structural framing, where applicable. Wallboard and non-combustible board should be fastened to the framing with at least 1-1/4 in. (32 mm) long screw fasteners, located within 1-1/2 in. (38 mm) from each corner, and at no more than 12 in. (305 mm) intervals along the joint length.

The wall-board joints should be finished with a Taping Coat, followed by at least two subsequent Finish Coats of joint compound.

For the initial Taping Coat, it is critical that a general- purpose chemically hardening joint compound, such as SHEETROCK™ Brand Durabond™ Setting-Type Joint Compound, be used to fill the joint and embed the mesh tape. Fiberglass-mesh tape is recommended because it will provide a more crack-resistant joint than one finished with paper tape. Let the Taping Coat properly cure before applying subsequent Finish Coats.

For the second and third finishing coats, it is acceptable to use a light-weight joint compound and standard application, curing and sanding methods.

Do not operate the fireplace during the drywall finishing process. Allow the finish coat to cure for at least 24 hours prior to using the appliance.

Retain 12 mm clearance between plasterboard and vertical sides of unit. Butt join plasterboard and white insulation board at top of heater. USING ONLY FIBERGLASS TAPE finish insulation board to plasterboard as per normal plasterbaord procedures. Ensure that top coat finish extends down to top of heater, as indicated in diagram below. Insulation board will remain exposed as part of the finished plaster face.

Gas Pipe Requirements

1.If polyethylene composite gas pipe is to be used, a clearance of 150 mm must be maintained from all flues.

2.Polyethylene composite gas pipe must not be used as the final connection onto the heater.

3.Leave a 1 m. tail of 1/2 in. (13 mm) copper pipe.

Painting

If desired finishing includes a painted wall, 100% acrylic latex with compatible primer is recommend around the appliance. Oil-based or standard acrylic paints may discolor due to heat exposure.

Wallboard Joint-Crack Prevention and Repair

Wallboard joints around the fireplace will be affected by exposure to elevated temperatures, along with other en- vironmental and structural factors. The specific methods presented in the previous section will help prevent or minimize development of cracks.

If a crack does emerge adjacent the fireplace, it can be permanently repaired by filling it with spackling paste or paintable latex caulk, followed by repainting.
