BURNER FLAME ADJUSTMENT

The main burner flame should be a blue flame somewhere between a long blue flame and a short, sharp flame that tends to blow off the ports. If flame is short, very sharp or blowing, the burner air shutter should be closed enough to obtain a long blue flame (see Figure 30). Long yellow flame produce excess carbon monoxide and could cause sooting.

TO SHUT OFF

1.For temporary shutoff, turn off electri- cal power to unit either by wall switch or remote control.

2.For long term shutoff, depress the gas valve cock valve, located under the fire- box, turn clockwise to the OFF position.

OPERATING GUIDELINES AND MAINTENANCE INSTRUCTIONS

1.Upon completing your gas line connec- tion, a small amount of air will be in the lines. When first lighting the appli- ance it will take the appliance a few minutes to purge the air. Once purging is complete, the pilot and burner will light and operate as indicated in the instruction manual. Subsequent light- ing of the appliance will not require such purging.

1.When lit for the first time, the appli- ance will emit a slight odor for an hour or two. This is due to the “curing” of the logs and “burn-in” of internal paints and lubricants used in the manufactur- ing process.

2.Keep control compartment, logs burn- ers, and area surrounding the logs clean by vacuuming or brushing at least twice a year. Do not vacuum the mineral wool located in the front of the burner assembly.

3.Always turn off gas to pilot before cleaning. For example relighting, refer to the lighting instructions.

4.Aqualified field service technician should inspect the appliance and venting system before use or at least annually.

WARNING: The logs can be hot. Handle only when cool.

5.Always keep the appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

6.Never obstruct the flow of combustion and ventilation air. Keep the front of the appliance clear of all obstacles and materials.

7.Never leave children unattended when the appliance is operating.

MAINTENANCE

WARNING: Turn off gas and electrical power before servicing appliance. It is recommended that a qualified serviceman perform these checkups at the beginning of each heating season.

In order to properly clean the burner and pilot assembly remove the logs exposing the burner and pilot assembly.

CLEANING BURNER AND PILOT

Clean all foreign materials from the top of burner and from bottom panel below. Check to make sure that burner orifice is clean. Visually inspect pilot. Brush or blow away any dust and lint accumulations. If pilot orifice is plugged, disassembly maybe re- quired to remove any foreign materials from orifice and/or tubing. When appliance is put back in service, check pilot flame patterns (see Figure 29).
