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 replace 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 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.

Cleaning the Standing Pilot

Control System

The burner and control system consists of:

• main burner

• pilot burner

• gas orifice

• thermopile

• combination millivolt gas valve

Most of these components may require only an occa- sional checkup and cleaning and some may require ad- justment. If repair is necessary, it should be performed by a qualified technician.

In order to properly clean the burner and pilot assembly, turn off the gas to the unit, remove the window frame panel and logs exposing the burner and pilot assembly. Clean all foreign materials from the top of the burner. Check to make sure that burner parts are clean. Visu- ally inspect pilot. Brush or blow away any dust or lint accumulation If pilot orifice is plugged, disassembly may be required to remove any foreign material from the orifice or tubing.

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

Typically, the top 1/8" of the thermopile should be en- gulfed in the pilot flame. (Fig. 19)

Cleaning Catalytic Filters

(UVC Only)

The catalytic filters require cleaning at least once a year to work effectively.

To clean catalytic filters:

1.From inside the combustion area, remove the 4 hex nuts holding the filter; lower filter down and out.

2.Clean the outer surface of the filter with the brush attachment of your vacuum sweeper to remove loose dirt.

3.Submerge the filter in a mild soapy water solution, then rinse thoroughly with distilled or deionized water.

4.Replace in heater when dry.

5.Repeat with second filter.
