Congratulations on your purchase of the 
Tucson Model 8701, Gas-Fired Direct-Vent 
heater. The Tucson, by Hearthstone, 
incorporates the latest in balanced vent gas 
technology, which will provide you with 
clean, efficient heat for years to come. The 
combination of natural stones and cast iron 
gives the Tucson a pleasing look that is 
maintained with minimum care. 
 
The Tucson will provide you with years of 
practical and convenient service. However, 
as with any gas appliance, the unit must be 
properly and safely installed and maintained 
by qualified service personnel to ensure safe 
and trouble-free operation. 
 
Your Tucson is equipped with a standing 
pilot which: 

1.

 

Generates a milli-volt signal that 
powers the wall-mounted thermostat 
and; 

2.

 

Lights the main burner when the 
thermostat calls for heat. 

 
This unit is equipped with an On/Off/T’stat 
switch and a variable output control. The 
variable output control is located on the gas 
control valve. It allows you to vary the heat 
output, along with the flame height to suit 
personal taste. Heat output can be reduced 
{set to “LOW”} during the Fall and Spring, 
when the need for heat is reduced and 
increased {set to “HIGH” during Winter 
months, when the need for heat is the 
greatest. 
 
A wall-mounted thermostat is provided by 
Hearthstone. Regardless of how you set the 
variable output control, when the optional 
thermostat is installed and the On/Off/T’stat 
switch is set to “T’stat”, the wall-mounted 
thermostat will control the on/off cycling of 
the unit. At any time, you can override the 

thermostat with the On/Off/T’stat switch by 
setting it to “ON” or “OFF”. 
 
The Unit can also be equipped with an 
optional blower-fan kit which turns on and 
off independently of the burner flames. The 
fan switch allows you to turn the fan on or 
off and control the speed of the fan to suit 
your needs.  The fan will automatically turn 
on when the stove is hot, and cycle off when 
the unit cools. 
 
Also available are two different optional 
remote controls. Both of the remote controls 
are capable of turning the unit on and off. 
One of the optional remotes also allows you 
to control the temperature of the room from 
anywhere in the vicinity of the unit. If “ON” 
& “OFF” are the only controls required; use 
Kit # 90-56912. If you would like to control 
the temperature via the remote control, use 
Kit # 90-56914.
