The Tucson has a piezoelectric spark igniter 
(the push button located next to the gas 
control valve behind the valve access door), 
which ignites the pilot light by means of a 
spark at the pilot light assembly.  Do not 
attempt to light the unit with a match or by 
any means than the piezoelectric spark. 
 

Prepare for the lighting procedure by 
adjusting the thermostat (if equipped) to its 
lowest setting or OFF position. If the gas 
control knob is not in the OFF position, turn 
the knob fully clockwise to OFF. Locate the 
variable output control knob and turn it fully 
clockwise to the highest setting. 
 
Prior to lighting the unit for the first time, 
wait 5 minutes to  allow any residual gas 
within the unit to dissipate. Smell all around 
the appliance area for gas. Be sure to smell 
next to the floor because some gases are 
heavier than air and will settle on the floor. 
If you do not smell gas after this five-minute 
period, proceed with the lighting procedure. 
If you do smell gas,  DO NOT proceed with 
the lighting procedure. Instead,  immediately 
refer to the What To Do If You Smell Gas 
Warning, on the cover of this manual. 
 
WARNING: The valve control has an 
interlock device. After shutting off all gas 
flow, the pilot burner cannot be relit until 
the thermocouple has cooled, allowing the 
electromagnet to be released (approx. 60 
seconds). The gas control knob is designed 
to be operated by hand. Do not use any tools 
during this  operation. Damaged knobs may 
result in serious injury. 
 

Once the Tucson has been set in place, 
connected and assembled as described in the 
Clearances To Combustibles, Venting 

Components & Configurations, Electrical 
Connections, And Gas 

Supply and 

Connections sections of this manual, the unit 
is almost ready to be lit for the first time. 
The manufacturer tests each unit prior to 
shipment, so ignition should take place 
without failure. However, a number of small 
adjustments may be necessary to 
compensate for variations in gas pressure, 
altitude, and other factors particular to each 
installation. 
 

The gas control valve is equipped with a 
variable output control. This control varies 
the  rate of heat produced by the unit by 
varying the gas pressure to the main burner 
tube. A combination of heat output and the 
thermostat setting affect the length of the 
burn cycle. If your stove turns on and off too 
often, try, first, reducing the burn cycle by 
turning the HI/LOW knob, on the control 
valve, to a lower setting. Using the variable 
output control, the heat output of the unit 
can be reduced for mild fall and spring 
months, or maximized for the colder winter 
months. This adjustment can be made, by 
the homeowner, as necessary by turning the 
variable output control knob to “HI”, “LO” 
or any setting in between. 
 

The air shutter is used to regulate the air-to-
gas combustion mixture, which in turn 
influences the size and color of the flames. 
The air shutter has been positioned in the 
general location needed for the type of gas 
being used, however, if the unit is not 
burning as well as it should, then the air 
shutter may need adjusting. The air shutter 
may need adjustment once the unit has been 
installed to compensate for variations in 
supply line pressure, restriction plate 
position, altitude, gas type conversions, and 
other variables.
