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 TUCSON FOR THE
FIRST TIME AND ADJUSTMENTS TO THE UNIT
SHOULD BE PERFORMED BY QUALIFIED
SERVICE PERSONNEL.
Lighting Instructions
Use a gas sniffer device or smell all around the
appliance area for gas. Be sure to 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:
For the Tucson ST:
plug the AC/DC power
transformer into the nearest 120V electrical outlet
and/or install batteries in the battery holder.
1. Open the gas supply to the valve.
2.
On the control panel, switch the
ON/OFF/T’’STAT switch to the ON position.
3. Switch the pilot to CPI mode and turn up the
regulator on the valve.
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 main burner should
ignite seconds later.
For the Tucson DX:
connect the power cord from
the Fan Control Module to the nearest 120V
electrical outlet.
1. Open the gas supply to the valve.
2. Slide the ON/ REMOTE/OFF switch to the
ON position.
3. Switch the pilot to CPI mode
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 main burner should
ignite seconds later.
Using the Remote:
The Remote and Receiver must be synchronized
before initial use, and after every battery change (for
instructions, see page 39).
Smoke and Fumes Warning
When lit for the first time, the Tucson 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 the first 10 to 20 minutes of operation.
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 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 Tucson is set in place, connected and
assembled 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
Figure 17)
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. Controlling
the Tucson by a remote or wall-mounted thermostat
may become erratic, nonexistent, or the unit may go
