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, alternately,
while the appliance is in operation.
Adjust the flame height as desired after lighting
the appliance by rotating the variable adjustment
control knob located on the front of the valve
(refer to Figure 2). (An extension is provided to
this knob so that the adjustment may be made
at the modesty panel.)
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 materials,
etc. It is important that control compartments,
burners and circulating air passageways of the
appliance be kept clean and clear of obstruction
of venting and combustion air.
4. Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re-lighting,
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 contin-
uous burning pilot flame. Exercise caution when
using products with combustible vapors.
