Flame Check

A periodic visual check of the flames should be made. The pilot flame should always be present when the appliance is in opera- tion. (Fig. 10)

In normal operation (at full rate for approximately 15 minutes) the following flame appearance should be observed:

Main BurnerFlame: The flame should be yellow in color and should extend about 6 inches above the large front log.

Typical flame shape as seen in Figure 11.

NOTE: For your safety, the appliance is equipped with an oxygen depletion system. The system senses the oxygen in the atmosphere and switches off the gas supply in case the level of oxygen falls below a safe level. It must not be altered in any way.

Managing Heat Output

When installed in a wood burning fireplace, the heat output from the appliance can be controlled by the position of the flue damper if it is installed in a wood-burning fireplace.

The damper setting should be fully closed for maximum heat output, partially closed for less heat output and fully open for minimum heat output.

The appliance may be used in a working solid fuel burning fire- place with the flue damper closed only if unvented appliances are permitted by local state and city codes. It may also be

operated as a decorative appliance whose prime function lies in the aesthetic effect of the flames when installed in a solid fuel burning fireplace with the flue damper open. If unvented heat- ers are not permitted, the fireplace vent damper must be locked at a minimum vent area of 15 sq. ins.

Whenever the appliance is operated with the fireplace’s flue damper closed, glass doors - if present - must be open and the outside air damper and the ash dump (if the fireplace is equipped with either one) must be closed.

Maintenance

Cleaning

CAUTION: Before cleaning or moving logs or other parts of the unit, be sure to read the section on important safeguards.

Cleaning should be done before the logs are used each year and after long periods of non-use.

All cleaning should be carried out when the appliance is cold.

Only limited cleaning will be required under normal use. Dust- ing the front grate or the control knob panel may be required occasionally. Do not use any cleaning fluids to clean the logs or any other part of the appliance.

If the flames show any unusual shapes or behavior, or if the burners fail to ignite properly, then the burner holes may require cleaning. If this occurs contact your nearest dealer to get the appliance serviced.

Alternatively, the appliance can be cleaned by removing the top, front and rear logs. Handle the logs gently so as not to damage them. Always lift each log by holding it carefully at each end.

After the logs are removed allowing access to the burner area, use a vacuum cleaner to carefully remove dust, spider webs and loose particles from the base, logs and from around the burner. Gloves are recommended to prevent the ceramic fibers that compose the logs from pricking your skin. If the skin is pricked, wash gently with soap and water. Use extreme cau- tion in clearing around the pilot (ODS). The pilot should not be moved or altered from the original factory setting (Pilot to burner preset location). The burner should not be removed or taken out of it’s locked and secure position (proper location of burners are critical).
