8.Apply a heavy bead of waterproof caulking 2 inches above the flashing. Slide the storm collar around the air terminal and down to the caulking. Tighten to ensure that a weather- tight seal between the air terminal and the collar is achieved. Attach the other storm collar centered between the air intake and air exhaust slots onto the air terminal. Tighten securely. Attach the rain cap.

8.Continue adding rigid venting sections, sealing and securing as above. Attach a 5" collapsed telescopic pipe to the last section of rigid piping. Secure with screws and seal. Repeat using a 8" telescopic pipe.

9. Run a bead of high temperature sealant around the outside of the 5" elbow. Pull the adjustable pipe a mini- mum 2" onto the elbow. Secure with 3 screws. Repeat with the 8" 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.

It is best to frame your fireplace after it is positioned and the vent system is installed. Use 2x4's and frame to local building codes.

See PAGE 14 for bar type / countertop installation.

GAS INSTALLATION

1.Move the fireplace into position and secure to the floor using #10 hex head screws (not supplied).

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

3.For ease of accessibility, an optional remote wall switch or millivolt thermostat may be installed in a conven- ient 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

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

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

4.Install the rigid black pipe, ½" 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 adapter fitting is required between the gas valve and the copper tubing or flex connector.

Do not kink flexible connector.

5.Check for gas leaks by brushing on a soap and water solution.

Do not use open flame.

6.Mark the appropriate boxes on the rating plate label to indicate the model type.

MANTLE INSTALLATION

Combustible mantle clearance can vary according to the mantle depth. Use the graph to help evaluate the clear- ance needed. The three-sided top extension piece may be removed if non-combustible framing is faced with a non-

combustible material.	FIGURES45a-b
