DV425TR DIRECT VENT ROOM HEATER
02/01 Page 50 250-5533
FAN SPEED ..........................If the optional blower is installed, this knob controls the speed of the blower that
pushes the heated air into the room.
MAIN BURNER.....................This control is used to turn the fireplace on and off.
PILOT IGNITOR ...................The pilot ignitor is used only to start the pilot. When pressed, it sends an
electrical charge to the pilot assembly. This creates a blue spark directly next to
the pilot, igniting the pilot flame.
VALVE CONTROL ................This knob is used to control gas to the stove and for starting the pilot. There
are three positions, ON, OFF, & PILOT. The pointer on the panel indicates the
position of the knob.
COMFORT CONTROL..........This knob controls the flame height from low (“LO”) to high (“HI”).
NOTE: If using a remote control wall switch, or thermostat, the On/Off Switch must be left “OFF”. Turning the
On/Off Switch “ON” will keep the stove on continually.
NORMAL OPERATING SOUNDS
Blower.....................If the optional blower kit is installed, the160 cfm blower will circulate heated air into
the living area. It produces a whirring sound which increases in volume as the speed
is increased.
Pilot Flame .............The pilot flame remains on constantly and makes a “whisper” sound.
Gas control valve...As the valve opens and shuts down it will click.
Burner pan .............The burner pan is located beneath the logs. It distributes the gas producing a clean,
efficient and aesthetic burn. As the main burner gets up to temperature a creaking sound
will be heard. This is the expansion of the metal. The sound will cease once the fireplace
is up to temperature but may return upon cool down.
Snap disc................This part may produce a clicking sound as the blower turns on and off if blower is left
in the ‘on’ position.
Heat Exchanger .....A normal expansion and contraction (ticking) sound may be heard.
Read this entire manual prior to using the fireplace. Pay particular attention to the “Safety Precautions” section
on pages 3-5. Failure to follow the instructions may result in property damage, bodily injury, or even death.
