DVM Series Direct Vent Gas Fireplace

WARNING

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 opening 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

normal operation. The pilot flame must always be pres-

ent when the fireplace is in operation. Figure 65. The

pilot flame has three distinct flames, one engulfing the

thermopile, one engulfing the thermocouple or sensor, and

the other reaching to the main burner.

BURNER

Inspect area around the injector. Remove any lint or foreign

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

normal 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 66

If the flame is blue and only in the center, turn off unit and

let cool. After unit is cool, remove logs and check to make

sure rock wool is placed correctly. Replace logs.

NOTE: The type of installation, vent system configuration,

and wind effects may cause the flame patterns to vary.
