8.Continue adding rigid venting sections, sealing and securing as above. Attach a 4" collapsed telescopic pipe to the last section of rigid piping. Secure with screws and seal. Repeat using a 7" telescopic pipe.

9. Run a bead of high temperature sealant around the outside of the 4" elbow. Pull the adjustable pipe a mini- mum 2" onto the elbow. Secure with 3 screws. Repeat with the 7" telescopic pipe.

10.In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent any materials, such as insulation, from filling up the 1" air space around the pipe.

RESTRICTING VERTICAL VENTS

Vertical terminations may display a very active flame. If this appearance is not desirable, the vent exit must be restricted using restrictor supplied. This reduces the velocity of the exhaust gases, slowing down the flame pattern and creat- ing a more traditional appearance.

1. Remove all obstructing obsta- cles i.e.: brick panels, logs, etc.

2.Remove the baffle plate from the rear wall of the firebox, exposing the two screws from the flue pipe assembly.

3.Line up the "A" holes on the restrictor plate with the pipe assembly holes and replace the screws.

4.Replace brick panels, logs, etc.

GAS INSTALLATION

Proceed once the vent installation is complete.

1.Route a 3/8" N.P.T. black iron gas line, 1/2" type-L copper tubing or equivalent to the fireplace.

2.For ease of accessibility, an optional remote wall switch or millivolt thermostat may be installed in a convenient location. Route 2 strand (solid core) millivolt wire through the electrical hole located at the bottom left side of the unit. The recommended maximum lead length depends on wire

size: WIRE SIZE		MAX. LENGTH
14	gauge	100 feet
16	gauge	60 feet
18	gauge	40 feet

Attach the two leads to terminals 1 and 3 located on the gas valve.

Purge all gas lines with the glass door of the fire- place open. Assure that a continuous gas flow is at the burner before closing the door.

MOBILE HOME INSTALLATION

The fireplace is equipped with two 1/4" diameter holes located in the front left and right corners of the base. For mobile home installations, the fireplace must be fastened in place. Use #10 screws, inserted through the holes in the base to secure. It is recommended that the fireplace be secured in all installations.

FRAMING

Note: In order to avoid the possibility of exposed insulation or vapour barrier coming in contact with the fireplace body, it is recommended that the walls of the fireplace enclosure be “finished” (ie: drywall/ sheetrock), as you would finish any other outside wall of a home. This will ensure theat clearance to combus- tibles is maintained within the cavity.

It is not necessary to install a hearth extension, but the fireplace should be raised up to be flush with either the hearth or the finished floor.

When roughing in the fireplace, raise the fireplace to ac- commodate for the thickness of the finished floor materi- als, i.e. tile, carpeting, hard wood, which if not planned for will interfere with the opening of the lower access door and the installation of many decorative flashing accessories.

Objects placed in front of the fireplace should be kept a minimum of 48" away from the front face.

PROTRUDING FINISH

Non-combustible material (brick, stone or ceramic tile) may protrude over the black painted surface of the fireplace front and is required for use in conjunction with the GD425 kit. This kit is designed to accommodate a noncombus- tible material to a maximum finished thickness of 3/4".

*When using the optional ornamental facia and panels, the minimum height from the top of the unit to the mantle is 7".

**A steel stud header is recommended, however tradi- tional combustible header material may be used.

Do not connect either the wall switch, thermo- stat or gas valve to electricity (110 volts).

3.Install rigid black pipe, 1/2" type-L copper tubing or, if local codes permit, a 3/8" flex connector and shutoff valve to the gas line and the fireplace gas valve. Seal and tighten securely. An adaptor fitting is required between the gas valve and the copper tubing or flex connector. DO NOT KINK

THE FLEXIBLE CONNECTOR.

4.Check for gas leaks by brushing on a soap and water solution. DO NOT USE OPEN FLAME.

BLACK PAINTED FIREPLACE SURFACE

Tiles must not pro- trude past the inner edge of the fireplace frame to avoid inter- ference with the GD425 installation.
