Maintenance
Burner and Burner Compartment
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. FK24/FK12 Fan Assembly
The fan unit requires periodic cleaning. At least once per month in the operating season open the lower louvre panels and wipe or vacuum the area around the fan to remove any build up of dust or lint.
Brass Trim
Clean the brass trim pieces using a soft cloth lightly dampened with lemon oil. Do not use water or household cleaners on any brass components.
Cleaning the Standing
Pilot Control System
The burner and control system consist of:
• burner | • gas orifice |
• pilot assembly | • thermopile |
•millivolt 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 burner’s flame characteristics are steady, not lifting or floating.
Typically, the top 3/8” to 1/2” of the thermopile should be engulfed in the pilot flame. (Refer to Page 25, Figure 47)
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.
The primary air shutter is set at factory and should only be adjusted, if necessary, by a qualified service technician.
