Congratulations on your purchase of the Tucson
Model 8702, Gas-Fired Direct-Vent heater. The
Tucson, by Hearthstone, incorporates the latest in
direct vent gas technology, which will provide you
with clean, efficient heat for years to come. The
combination of natural stones and enameled or
painted 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.

3. Heat Wave Baffle for maximum radiant heat
output.
4. Platinum Bright Embers
5. The option to toggle back and forth between an
Intermittent (IPI) or Continuous (CPI) pilot mode.

continuously keeping the firebox warmer
thus promoting better draft in colder
climates.

outages.
