Burner and Burner Compartment

Maintenance

It is important to keep the burner and the burner compartment clean. At least once per year the logs and lava rock/ember material should be removed and the burner compartment vacuumed and wiped out. Remove and refit the logs as per the instructions in this manual.

Always handle the logs with care as they are fragile and may also be hot if the fireplace has been in use.

Cleaning the Standing

Pilot Control System

The burner and control system consist of:

burner tube

gas orifice

pilot assembly thermopile

gas valve

Most of these components may require only an occasional checkup and cleaning and some may require adjustment. If repair is necessary, it should be performed by a qualified technician.

1.Turn off pilot light at gas valve.

2.Allow fireplace to cool if it has been operating.

3.Remove window frame assembly. (Refer to Window Frame Assembly Removal section.)

4.Remove logs.

5.Vacuum burner compartment especially around orifice primary air openings.

6.Visually inspect pilot. Brush or blow away any dust or lint accumulation.

7.Reinstall logs.

8.Ignite pilot - Refer to Lighting Instructions.

9.Reinstall window frame assembly.

To obtain proper operation, it is imperative that the pilot and burnerʼs flame characteristics are steady, not lifting or floating.

Typically, the top 3/8” to 1/2” of the thermopile/sensing electrode should be engulfed in the pilot flame. (Refer to Page 24, Figure 48)

To adjust pilot burner: (by qualified service technician)

1.Remove pilot adjustment cap

2.Adjust pilot screw to provide properly sized flame.

3.Replace pilot adjustment cap.

Cleaning Electronic Ignition System

The Electronic Ignition burner/control system consists of:

main burner

gas orifice

pilot burner

24VAC valve with transformer

Taking care of the Electronic Ignition units is identical to taking care of the Standing Pilot models.

Battery Replacement for Ignitor Module

1.Open control panel box door.

2.Remove the extension knob(s).

3.Remove the valve cover by removing the two (2) screws securing the valve cover plate to the box. While holding the valve cover plate with one hand, disconnect the wiring to the switch and the pilot indicator. NOTE: Do not allow the valve cover plate to hang from the pilot indicator wires as this could damage the wires.

4.Replace the battery (AA) in the ignitor module lo- cated at the top left corner.

5.Replace wires, valve cover, extension knob(s) in reverse order. NOTE: The pilot indicator body is labelled +/-, make sure the positive wire on the pilot indicator goes to ground and the negative goes to the plug between the valve and the thermocouple.
