Operation - Mr. Heater MH9BX Operating Instructions And Owner's Manual

NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING!
• When the unit is lit, there should be
about a quarter inch (1/4") border
around the tile that will not turn bright
orange. This is normal.
• When operating the heater for the first
time, the top area of the reflector may
discolor. This is also normal and is no
reason for concern.
• The protective grill on the front of this
heater is coated with a special high-
temperature resistant paint. When the
heater is used for the first time, the
grill may give off noticeable smoke
or fumes. This is normal and will not
occur during subsequent uses. The
fumes are not harmful.
• When operating the heater at
altitudes over 7,000 FT. above sea
level, the unit may not burn as
bright as in lower altitudes. This
is normal. At higher altitudes,
the heater may shut-off. If this
happens, provide fresh air, wait 5
minutes and re-light. Due to local
atmospheric conditions heater may
not relight.
• Operating time will be approximately
3 to 6 hours on a one 1lb cyclinder
and 48 to 1 10 hours on a 20 lb
cylinder (based on "HI" and "LO"
settings). Due to the properties of
LP gas, runtimes can be significantly
reduced when operating continuously
at temperatures below 20ºF. Use of a
20 lb. tank is recommended in these
conditions.
• When moving heater when lit or
bumping heater setting it down, the
tip over switch may shut off heater. If
this happens, re-light.
• Due to natural operation of small
tanks, condensation may build up on
tank and drip on surface under heater.
