CAUTION: NEVER LOCATE INLET WHERE IT CAN BE BLOCKED BY SHRUBS, SNOW DRIFTS, ETC. NEVER LOCATE INLET IN GARAGE OR ANY AREA WHERE THERE IS ANOTHER FUEL BURNING APPLIANCE OR PRODUCTS EMIT- TING COMBUSTIBLE GASES SUCH AS PAINT, GASOLINE, ETC. IN COLD CLIMATES, IT IS RECOMMENDED THE COMBUSTION AIR DUCT BE INSULATED.

Outside combustion air ducting may be run upwards or vertically through framing and ceil- ing joists, with the hood installed through an outside wall and 3' (1 m) below the B-Vent termination. Ducting may also be run down- ward through floor joists and under the home to a ventilated crawlspace not considered part of the living area of the home.

Note: Do not terminate combustion air kit in attic space under any circumstances.

After completing the installation of the op- tional combustion air vent system the actua- tor arm must be put in service and tested to ensure proper operation before completing any enclosure around the firebox. Failure to do so may result in extensive and costly rework.

Operate the actuator through several cycles including the closed position. Ensuring proper operation and freedom of movement. Return the actuator arm to the closed position.

Step 8. Installing Logs and Rockwool –

The logs are packaged within the firebox. The bag of rockwool is in the lower control com- partment. Refer to the Homeowner's Care and Operating Instructions for detailed placement instructions for the logs and rockwool.

Step 9. Optional Glass Doors/Enclosure Panel Availablity, Precautions and Instructions –

See the Homeowner's Care and Operating In- structions for a selection of glass doors/enclo- sure panels available for installation in these appliances. Installation Instructions for the doors/enclosure panels are provided with them.

•Never clean glass when doors or panel are hot due to operating the appliance.

•Glass and metal frames get hot. Use only the wooden handles to open and close the doors or to lift out panel.

CAUTION: THE APPLIANCE SHOULD ONLY BE OPERATED WITH THE GLASS DOORS FULLY OPEN OR FULLY CLOSED.

APPLIANCE OPERATION

Step 10. Checking the System –

With gas line installed, run initial system check- out before closing up the front of the unit. Follow the pilot lighting instructions provided in the Homeowner's Care and Operation In- structions. For piezo ignitor location see Fig- ure 24 on page 11 (millivolt appliances only).

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Note: Lighting instructions are also found on the pull-out label attached near the gas valve in the control compartment.

When first lighting the appliance, it will take a few minutes for the line to purge itself of air. Once purging is complete, the pilot and burner will light and operate as indicated in the in- struction manual.

Subsequent lightings of the appliance will not require such purging. Inspect the pilot flame (remove logs, if necessary, handling care- fully).

Millivolt Appliance Checkout

The gas control system on these appliances is a millivolt standing pilot type. It consists of a pilot burner, a piezo ignitor, a gas control valve, a burner assembly and an ON/OFF wall switch. A temperature limit switch is wired in series with the millivolt wall switch and gas control valve. If a higher than normal tempera- ture is sensed due to a blocked vent or pro- longed downdraft, the limit switch will open and cause the burner to shut off.

The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the outer edge.

The top ³⁄₈" (9 mm) at the pilot generator (thermopile) should be engulfed in the pilot flame (Figure 30 ).

If the pilot flame pattern is not as shown in Figure 30, adjust it as follows:

1.Remove the pilot adjustment cap located on the main gas valve.
