Lighting & Operation
WARNING: IF YOU DO NOT FOLLOW THESE
INSTRUCTIONS
EXACTLY,
A
FIRE
OR
EXPLOSION MAY RESULT CAUSING PROPERTY
DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.
CAUTION: LIGHTING THE DVI 44 FOR THE FIRST
TIME, AND ADJUSTMENTS TO THE UNIT SHOULD
BE
PERFORMED
BY
QUALIFIED
SERVICE
PERSONNEL.
Lighting Instructions
When lighting for the first time, use a gas sniffer
device or smell all around the appliance area for
evidence of leaking gas. Ensure you check next to
the floor because some gases are heavier than air
(propane). If you do not detect or smell gas, proceed
with the lighting procedure. If you do detect, or smell
gas, DO NOT proceed with the lighting procedure.
Instead,
immediately refer to the What To Do If
You Smell Gas Warning, on the cover of this
manual.
Pilot Light Warning
Do not attempt to light the unit with a match or by
any means other than the ignition system supplied
with the unit.
To Light the Stove:
Connect the power cord from the Fan Control
Module to the nearest 120V electrical outlet.
Avoid
connecting to an electrical circuit that has a
dimmer switch anywhere in it
– fan speed
modulation will be affected.
1. Open the manual shut-off for the gas supply
to the valve.
2. Slide the ON/ REMOTE/OFF switch to the
ON position.
The control system will beep several times when
lighting the unit for the first time until all air in the gas
line is purged. The pilot will ignite automatically
when the air is purged. The split main burners
should ignite seconds later.
Note:
In some installations, if the unit is set to
IPI (Intermittent Pilot Ignition), the main burner
may ignite, and go out several times until the
venting warms up and a good draft is
established. To minimize this false start, place
the unit into CPI (Continuous Pilot Ignition)
mode for at least 5 minutes before primary
burner ignition.
Using the Remote:
The
Remote
and
Control
Board
must
be
synchronized before initial use, and after every
battery change (for instructions, see page 38).
Smoke and Fumes Warning
When lit for the first time, the DVI 44 will emit some
smoke and fumes. This is normal “off-gassing” of
the paints and oils used in the manufacturing and
assembly of the unit. Open windows to vent the
room if necessary. The off gassing and fumes will
subside after several hours of operation on the
highest setting.
Odors and Impurities
A heater of this type may produce odors during
heater operation at any time due to impurities that
may exist in the immediate area or air around the
unit. Sources of impurities can be cleaning solvents,
paint solvents, cigarettes, candles, smoke, pet hair,
dust, adhesives, new carpet, and/or textiles. Such
odors will eventually dissipate. However, opening a
window or otherwise providing additional ventilation
to the area can alleviate the condition sooner. If any
odor persists, find and remove the cause, or contact
your dealer or an authorized service technician.
Initial Adjustments
Once the DVI 44 is installed as described in the
Clearances To Combustibles, Venting Components
& Configurations, Electrical Connections, and Gas
Supply and Connections
sections of this manual, the
unit is ready to be lit and adjusted to its particular
installation. Hearthstone tests each unit prior to
shipment, so ignition should take place without
failure. However, a number of small adjustments
may be necessary to compensate for variations in
gas pressure, altitude, and other factors particular to
each installation.
Pilot Adjustment
The pilot light is preset by the manufacturer and
should not need adjustment. The pilot light flame
should be large enough to engulf the sensor
(refer to
the following figure)
and to reach the light off ports
on the burner but not so large as to create excessive
noise or consume excessive gas.
However, it can be
adjusted by means of the pilot light adjustment
screw located on the gas control valve (see page
27). Controlling the DVI 44 may become erratic,
nonexistent, or the unit may go out if the pilot flame
