YEARLY MAINTENANCE PROCEDURES

WARNING! Failure to inspect and maintain the stove may lead to improper combustion and a potentially dangerous situation. The following procedures are recommended to be completed by a qualified technician once per year, preferably prior to the burning season.

1.Check the pilot flame. It should engulf approximately 3/8” of the top of the millivolt generator and engulf the top of the thermocouple (see illustration on page 52).

2.Shut off gas to the stove by turning the valve control knob to “OFF” and turning off the manual shutoff valve. Allow the stove to cool for 15 minutes. Remove the door.

3.Remove the logset (NOTE: the logs are fragile. If any log is cracked or deteriorated, replace it when reinstalling. Check the logs for sooting. A small amount of soot along the bottom of the logs is normal. If excessive sooting is found, the fireplace will require adjustment. Contact your dealer.

4.Clean the burner pan (especially in the burner holes and slots) and inspect the following:

a.Check for burner pan holes that are cracked, severely warped, plugged or corroded.

b.Make sure the burner pan assembly fits flat against the floor of the firebox.

5.Reinstall the logset. Inspect the door glass, if the door glass is damaged, contact your dealer for a replacement. Make sure the gasket along the perimeter of the glass contacts the face of the firebox and forms an airtight seal. If it does not, realign or replace the gasket to ensure an airtight seal. Reinstall door.

6.Inspect the area behind the side panels. Check the gas control valve and all of the gas lines. If any damage is found, discontinue use and contact your dealer for service.

7.Remove any debris or vegetation near the vent termination, outside the house ensuring that the flow of combustion and ventilation air is not obstructed. Contact your dealer if any sooting or deterioration is found near the vent termination.

8.Turn on gas and follow Lighting Instructions. The flames should be orange/yellow and not touch the top of the firebox. If the pilot or main burners do not burn correctly, contact your dealer for service. Monitor the blower operation.
