Outside Combustion Air Controls

Many appliances are equipped, when installed, with an outside (make-up air) vent system that is designed to provide the appliance with outside make-up air for combustion when in operation. The combustion air control lever for the outside air system is standard on all appliances but should not be operated if the complete system is not installed. Refer to Figure 4. When the complete outside air vent system is installed, the installer will remove the securing screw from the combustion air control lever located on the left side of the fireplace bottom opening.

If the securing screw has not been removed and you have reason to believe that you have a complete outside air system, contact your distributor to have your appliance inspected for the presence of the complete system. DO NOT assume that you have this system in place.

WARNING

Do not operate the shutoff lever unless a complete outside combus- tion air system has been installed with your appliance.

To open the outside air shutter, open the bottom control access panel, reach into control com- partment and pull the combustion air control lever all the way out. The outside air shutter should be fully open when the fireplace is in use and completely closed when the fireplace is not being used. Closing it when not in use will prevent outside cold air from entering the dwelling.

Step 13. Spillage Test and Safety Limit Switch Operation

Spillage Test

After appliance installation, perform this spill- age test to verify that proper venting conditions exist:

1 - Place unit in its normally-operated condi- tion, that is, with the glass enclosure panel in place.

2 - Close all doors and windows in the room. Turn on all exhaust fans in the house.

3 - Light the appliance.

4 - Wait 15 minutes.

5 - To check for venting action, start by holding a smoke producing device within an inch of one edge (side edge, not top or bottom edge) of the glass enclosure panel. The smoke should be drawn toward the edge of the glass enclosure panel. Continue the test by moving the smoke producing device along the entire length of both side-edges of the glass door.

6 - If the smoke is not drawn towards the edges of the glass door turn off the appliance and call a qualified service technican.

Manually-Reset Safety Limit Switch

This appliance is equipped with a manually-reset blocked flue safety limit switch. Refer to Figure 5 on Page 7 for its location. If, during appliance operation, the flame goes out (independently of the burner on/off wall switch), it may be due to the operation of this safety limit switch. First allow the appliance to cool. Remove top louver panel. Then reset the safety limit switch by pushing the red reset button, located between the wire terminals, on the back of the switch. See Detail A of Figure 5 for location.

The appliance should then relight and remain lit. Reinstall top louver panel. If the appliance does not relight, turn off the appliance and call for a qualified service technician.

To replace the blocked fl ue safety limit switch refer to Figure 5 on Page 7 (Details

B and C):

NOTE - This procedure should only be performed by a qualified service technician.

Important - Turn electrical power off before beginning this procedure.

1 - Lower the bottom control compartment access panel. Remove the glass enclosure panel: open the latch (located in the center of the unit front opening, under the firebox floor) securing the glass enclosure panel. Remove the panel by tilting it outward at the bottom and lifting it up. Set the door aside protecting it from inadvertent dam- age. See Figure 6 on Page 7.

2 - Remove the lintel securing screws (3) and then remove the lintel. One of the lintel cabinet top holes is shown in Figure 5 (Detail B).

3 - Remove the scoop securing screws (3) and then remove the scoop. See Figure 5 (Detail B).

4 - Remove the safety switch bracket securing screws (2), and pull the switch/bracket assembly, with low voltage wires attached, through the side panel slot into the firebox. See Figure 5 (Detail C).

5 - Replace the switch.

6 - Reinstall the switch/bracket assembly.

7 - Reinstall the scoop and lintel.

8 - Reinstall the glass enclosure panel.

9 - Raise the bottom control compartment access panel.

10 - The appliance should then relight and remain lit. If this does not occur, check unit for a blocked flue condition.
