AILY PERATION
The Tucson gas-fired heater is easily operated by
the homeowner once installed and adjusted by
qualified service personnel. The unit is controlled via
the wall-mounted thermostat during the heating
season. Set the thermostat to the desired room
temperature and the unit will cycle on and off as
required. By adjusting the variable output control
located on the gas control valve, the rate of heat
output can be varied
requirements of the season. Choosing a low flame
setting will result in longer burn cycles at a reduced
output, while choosing a high flame setting will result
in a shorter, hotter burn cycle. Through trial and
error, the homeowner can select the optimum flame
size for their setting and application.
During the summer non-heating season, switch the
wall thermostat to "OFF", and turn off the pilot. This
will improve the overall efficiency of the unit as the
heat from the pilot is wasted. When putting the unit
back into service, follow the lighting instructions
described on page 19.
When the unit is first lit, especially when cool, it is
normal to experience some condensation on the
inside of the window glass. This condensation will
burn off within the first few minutes of operation. If
continuous condensation on the window glass or
dripping water from any part of the unit or venting
system (chimney) is noted, immediately discontinue
operation of the unit and contact qualified service
personnel.

LEANING
WARNING: DO NOT CLEAN THE UNIT WHEN HOT.
The unit must receive regular cleaning on, under,
and around the stove to prevent the buildup of dust
and lint. The exterior surfaces of the unit can be
cleaned using soap, water, and a soft cloth. Do not
use abrasive or chemical cleaners and take care not
to meet the heating
to scratch the glass or enamel finish (if so equipped)
when cleaning the unit. The use of chemical wax
based cleaners or polishes are not recommended
due to the potential for discoloration or the enamel
when the residue of the cleaners or polishes is
exposed to heat.

IREBOX ILOT
The firebox must also receive periodic cleaning to
prevent the accumulation of dust, lint, and other
debris. To clean the firebox, set the thermostat to
the "OFF" position, and turn off the gas at the gas
control valve. When the unit is cool, unfasten the
front door and carefully remove the decorative
ceramic fiber log set, taking care not to damage the
logs or chip the enamel cast iron. Clean the firebox
burner tube and carefully vacuum the entire surface
of the log set. Thoroughly vacuum the ports (holes)
along the top of the burner tubes.
With the decorative ceramic fiber logs out of the
firebox, fasten the door shut and momentarily light
the unit according to the lighting instructions
described on page 19. Check to insure a flame is
burning from each burner port. The pilot flame
should be large
sensor/thermocouple. Turn the unit off by setting the
thermostat to "OFF" and turning off the gas control
valve. Allow the unit to cool. Check and clean any
burner ports that are not burning or not burning
properly. Clean burner ports using soft a soft brush
or vacuum cleaner. If the pilot flame height needs
adjustment, it should be adjusted by qualified
service personnel as described on page 20.
