Variable Flame Adjustment (Millivolt); Glass Cleaning; Maintenance - Superior DT-400 Homeowner's Care And Operation Instructions Manual

If your electronic appliance is not equipped
with a wall switch or remote control, the main
burner must be turned off and on with the gas
control switch. Toggle the switch from ON to
OFF to operate the main burner .

Variable Flame Height Adjustment
( Millivolt Appliances only)
1. All Millivolt appliances are equipped with a
variable gas control valve. Flame height for
these models may be adjusted through a range
between fixed low and high settings, alter-
nately, while the appliance is in operation. Ad-
just the flame height as desired after lighting
the appliance by rotating the variable adjust-
ment control knob located on the front of the
valve (refer to Figure 3 - SIT, 4 - Honeywell) .
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

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.
Note: Clean glass after first two weeks of
operation.
WARNING: DO NOT USE ABRASIVE
CLEANERS. NEVER CLEAN THE GLASS
WHEN IT IS HOT.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Maintenance

IMPORTANT: TURN OFF GAS AND ANY
ELECTRICAL POWER BEFORE SERVICING
THE APPLIANCE.
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. However, more frequent periodic inspec-
tions and cleanings should be performed by
the homeowner. Homeowner must contact a
qualified service technician at once if any
abnormal condition is observed.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by
whom they should be performed. Always
verify proper operation of the appliance after
servicing.
