BBV, SBV Series Natural Vent Gas Fireplaces

Turn off gas before servicing fireplace. It

is recommended that a qualified service

technician perform these check-ups at the

beginning of each heating season.

BURNER, PILOT AND CONTROL COMPART-

MENT

Keep the control compartment, logs and burner areas

surrounding the logs clean by vacuuming or brushing at

least twice a year. Make sure the burner porting, pilot air

opening and burner air openings are free of obstructions

at all times.

PILOT FLAME

The flames from the pilot should be visually checked as

soon as the heater is installed and periodically during nor-

mal operation. The pilot flame must always be present

when the fireplace is in operation. Figure 31. The pilot

flame has three distinct flames, one engulfing the thermo-

pile, one engulfing the thermocouple or sensor and the

other reaching to the main burner.

BURNER

Inspect area around the injector. Remove any lint or for-

eign material with a brush or vacuum.

BURNER FLAME

The flames from the burner should be visually checked as

soon as the heater is installed and periodically during nor-

mal operation. In normal operation, at full rate, and after

operating for about 15 to 30 minutes, the flame should be

yellow and slightly taller than the rear log. Figure 32

NOTE: The type of installation, vent system configu-

ration and wind effects may cause the flame patterns

to vary.
