LIGHTING THE UNIT FOR THE FIRST TIME
CAUTION: LIGHTING THE DVI-HT FOR THE FIRST
TIME AND ADJUSTMENTS TO THE UNIT SHOULD
BE PERFORMED BY QUALIFIED SERVICE
PERSONNEL.
Smoke and Fumes Warning
When lit for the first time, the unit 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
usually subside after the first 10 to 20 minutes of
operation.
Odors and Impurities
A heater of this type may produce odors during
heater operation due to impurities that may exist in
the immediate area. Sources of impurities can be
cleaning solvents, paint solvents, cigarettes, smoke,
pet hair, dust, adhesives, new carpet, and/or textiles.
Such odors will dissipate. However, opening a
window or otherwise providing additional ventilation
to the area can alleviate the condition. If any odor
persists, contact your dealer or an authorized
service technician.
Pilot Light Warning
The DVI-Ht has an electric spark igniter, which
ignites the pilot light by means of a spark at the pilot
light assembly. Do not attempt to light the unit with a
match or by any means other than the electric spark
igniter
Prepare for Lighting
Prepare for the lighting procedure by adjusting the
thermostat to its lowest setting or OFF position. If the
gas control knob is not in the OFF position, turn the
knob fully clockwise to OFF. Locate the variable
output control knob and turn it fully counter-
clockwise to the highest setting.
Initial Adjustments
Once the DVI-Ht has been set in place, connected
and assembled as described in the Assembly of the
Unit, Electrical Connections, and Gas Supply &
Connections sections of this manual, the unit is
ready to be lit for the first time. Each unit is tested
prior to shipment by the manufacturer, 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.
Prior to lighting the unit for the first time, wait 5
minutes to allow any residual gas within the unit to
dissipate. Smell all around the appliance area for
gas. Be sure to smell next to the floor because
some gases are heavier than air and will settle on
the floor. If you do not smell gas after this five-
minute period, proceed with the lighting procedure.
If you do 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.
Lighting Instructions
The gas control knobs are located behind the valve
door at the bottom of the unit.
1. Set the on/off/T-stat switch or thermostat to the
off position.
2. Unplug the blower accessory, if so equipped
3. Push in and turn gas control knob clockwise to
“OFF”.
(If not previously lit, the knob should be
in this position.)
1. 4. Wait (5) five minutes to clear out any gas. If
you then smell gas, STOP!
Smell all around the
appliance area for gas. Be sure to smell next to
the floor because some gases (LPG) are heavier
than air and will settle on the floor. If you smell
gas immediately follow the What To Do If You
Smell Gas! warning on the cover of this Manual.
If you do not smell gas, go to the next step.
2. 5. Turn gas control knob counterclockwise to
“PILOT”.
3. 6. Push in control knob all the way and hold
in.(You should hear the clicking of the Piezo
igniter in the firebox) Verify ignition of the pilot.
Continue to hold the control knob in for about 20
seconds after the pilot is lit. Release the knob
and it will pop back out. Pilot should remain lit. If
the pilot goes out, repeat the operation.
•
If knob does not pop out when released,
stop and immediately call a qualified service
technician or gas supplier.
•
If the pilot will not stay lit after several tries,
turn the gas control knob “OFF” and call a
qualified service technician or gas supplier.
