Variable Flame Adjustment; Glass Cleaning - Lennox Hearth Products MPLDV-30NM Care And Operation Instructions Manual

Operation of millivolt and electronic gas con-
trol systems are different. Before lighting and
operating your appliance determine if you
have a millivolt or electronic appliance.
Refer to Figure 1 for access to the gas control
valve. Millivolt appliances will be fitted with
the gas control valve shown in Figure 2 .
Appliances with electronic systems will be fit-
ted with the electronic valve shown in Figure 3 .
Familiarize yourself with the gas control valve
that your appliance uses.
Millivolt Appliances -
To light millivolt appliances refer to the de-
tailed lighting instructions found on page 12
( English ) and page 13 ( French ). Millivolt ap-
pliance lighting instructions may also be
found on the pull out lighting instruction
labels attached to the gas control valve.
Millivolt appliances are fitted with an ON/
OFF Rocker Switch for appliance ON/OFF
control. See Figure 1 for its location. Once
the pilot is lighted, the ON/OFF rocker switch
will control the appliance ON/OFF operation.
To operate: Toggle the switch between its
ON and OFF positions.
If your millivolt appliance is equipped with an
optional remote wall switch or remote control
kit and the pilot is lit, the appliance main
burner may be turned on and off with the wall
switch or remote control.
Electronic Appliances -
To light electronic appliances refer to the
detailed lighting instructions found in both
English and French on pages 14 and 15 of
these instructions respectively.

TO LIGHT YOUR APPLIANCE IN A POWER
• Install batteries in battery pack.
• Turn unit mounted switch or wall switch to
the ON Position.
• Unit should spark at pilot and light.
• Operate Normally.
• Replace batteries if needed.
• After power is restored, remove batteries.
Note: It is recommended that batteries not be
installed in the battery holder until a power
outage, or if the appliance is to be operated
solely with two (2) "D" batteries.
Refer to the Lighting Instructions on page 14 to
light the appliance in the event of a power failure.
Variable Flame Height Adjustment
(Millivolt And Electronic Appliances)
Variable Flame
Height Adjustment
1. All Millivolt and Electronic appliances are
equipped with a variable gas control valve.
Flame height for these models may be ad-
justed through a range between fixed low and
high settings, alternately, while the appliance
is in operation.
Adjust the flame height as desired after light-
ing the appliance by rotating the variable ad-
justment control knob located on the front of
the valve (refer to Figure 2) .

2. When lit for the first time, this appliance will
emit a slight odor for an hour or two. This is
due to the "burn-in" of internal paints and
lubricants used in the manufacturing process.
3. Keep lower control compartment clean by
vacuuming or brushing at least twice a year.
More frequent cleaning may be required due to
excessive lint from carpeting, bedding materi-
als, etc. It is important that control compart-
ments, burners and circulating air passage-
ways of the appliance be kept clean.
4. Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re-light-
ing, refer to the lighting instructions in this
manual. Instructions are also found on a pull-
out panel located on the floor of the appliance.
5. Always keep the appliance area clear and
free from combustible materials, gasoline and
other flammable liquids.
6. Remember, Millivolt appliances have a con-
tinuous burning pilot flame. Exercise caution
when using products with combustible vapors.

Glass Cleaning

WARNING: NEVER CLEAN THE GLASS
WHEN IT IS HOT.
It will be necessary to clean the glass periodi-
cally. During start-up it is normal for conden-
sation to form on the inside of the glass. This
can cause lint, dust and other airborne par-
ticles to cling to the glass surface. Also initial
paint curing may deposit a slight film on the
glass. It is therefore recommended that the
glass be cleaned two or three times with a non-
ammonia household cleaner and warm water
(a gas fireplace glass cleaner is recommended).
After that the glass should be cleaned two or
three times during each heating season, de-
pending on the circumstances present.
