INTRODUCTION
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.
READ THIS OWNER’S MANUAL
Operate and maintain this gas heater
according to the instructions in this manual.
For your safety, and years of trouble free
operation, read this manual in its entirety.
HEATER MUST BE INSTALLED AND
MAINTAINED BY QUALIFIED

OWNER’S INFORMATION
The installation must conform with local
codes or, in the absences of local codes, the
current National Fuel Gas Code, ANSI Z223.1
(NFPA 54) or CAN/CGA B149 Installation
Code. (Installer l’appareil selon les codes ou
règlements locaux, ou, en l’absence de tels
règlements, selon les Codes d’installation
CAN/CGA-B149.) Do not use this appliance
if any part was submerged under water.
Immediately call a qualified service
technician to inspect the heater and to
replace any part of the control system and
gas control that was under water. (Ne pas
se servir de cet appareil s’il a été plongé dans
l’eau, complètement ou en partie. Appeler un
technicien qualifié pour inspector l’appareil et
remplacer toute partie du système de contrôle
et toute commande qui ont été plongés dans
l’lau.)
DAILY OPERATION
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 to meet the
heating 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 29.
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.

UNPACKING AND INSPECTION
UNPACK AND INSPECT FOR DAMAGE
The Tucson is packaged by the manufacturer
to withstand shipment without damage.
However, damage can still occur during
transit; so take care to inspect for damage
when unpacking and installing the unit. If
any damage, or missing parts are detected,
immediately contact your dealer.
Do not install, or put into service, a
damaged or incomplete heater.
Caution: The stones and top grill are
NOT cemented, or otherwise permanently
fastened in place! We recommend your
Tucson be moved into place, venting
attached, gas and electrical connections
made, and any accessory blower installed
before installing the stone set, or top grille.
Inspect the Tucson for visible or concealed
damage. The unit should appear to be square
and true. The stone set should be whole and
without cracks, chips, or breakage. The
sheet metal parts should be smooth and free
of bends and dents. The enameled cast iron
should be free of chips or cracks. If visible
or concealed damage is found or suspected,
contact your dealer for instructions.

Hearthstone Quality Home Heating Products Inc Tucson Model #8701
23037-1

With the accessory box removed and set
aside, undo the lag bolts that fasten the unit
to the pallet. Take care not to mar or chip
the enameled legs. Have someone help lift
the stove off the pallet and set it into place.
The decorative ceramic logs supplied with
the Tucson are contained within the firebox.
Always use great care when handling the
decorative ceramic fire logs, as they are
fragile and subject to damage and breakage
if handled roughly. Open the firebox door
using a 1/8” Allen wrench screwdriver and
inspect the logs for damage. If a broken log
is encountered, contact your dealer for a
replacement. Otherwise, set the logs aside
until called for during the installation.
HEARTH REQUIREMENT/FLOOR
PROTECTION
The Tucson can be placed directly on a non-
combustible surface or wood floor. For
placement of the Tucson on carpeting, vinyl
tile or other combustible materials, the
appliance must be installed on a metal or
wood panel extending the full width and
depth of the appliance. Installations must
meet all local codes.
CLEARANCE TO COMBUSTIBLES
Due to high surface temperatures, the unit
should be located out of traffic areas and
away from furniture and draperies. Clothing
and other flammable material should not be
placed on or near the heater. When
positioning the unit always maintain
adequate clearances around air openings into
the combustion chamber and allow for
adequate ventilation. Minimum clearances
to combustibles must be maintained as
shown in the illustrations on page 12.
Note: The rear clearance to combustibles
will be determined by either the unit’s or the
vent pipe’s minimum clearance, depending
on whether the installation calls for vertical
rise within the room or a rear exit, through-
the-wall vent pipe.
Be sure to consider the need for access to
the gas control valve access door on the
front of the unit as well as full access for
periodic cleaning and servicing. Also
consider the location of the Optional Blower
Fan.
•Caution: These clearances represent
minimum distances in all cases, which,
through testing in an independent
laboratory to ANSI and CSA
standards, will prevent fire or
spontaneous combustion. We do not
control the combustible materials
exposed to heat by this product;
therefore, an assessment must be
made by the installer to prevent
consequential damage of walls and
flooring.

RESTRICTION PLATE
The restriction plate is used to control the
draft of the heater. Controlling the draft also
changes the aesthetics of the flame. The
restriction plate has eight settings, one (1)
being the lowest and eight (8) being the
highest. For a fast moving flame with lots
of action, use a low setting. For a slow, lazy
flame, a high setting should be used. See
Figure 11 for instructions on how to adjust
the restriction plate settings.
RESTRICTION PLATE POSITION
A vent restriction plate is available for the
appliance to adjust the flow rate of exhaust
gases. This ensures proper flames for the
wide variety of vent configurations and
efficiency. The restriction plate consists of a
rotating shutter below the starter section of
pipe and an adjustment plate with index
holes used to hold the shutter in a fixed
position. Depending on the vent
configuration, you may be required to adjust
the restriction plate position. Refer to page
14 for positioning of the restriction plate.
ADJUSTMENT TO RESTRICTION
PLATE
Remove the log set before adjusting the
restriction plate by following the log set
removal instructions on page 25. Make sure
the unit is cool before touching any part of
the firebox and log set. Remove the exhaust
baffle by removing the one screw in the
center of the baffle (refer to Figure 10). The
baffle will come out once the screw is
removed. Be careful not to drop the baffle
on the pan burner. Once the baffle is set
aside, check the restriction plate screw
location. There are eight locations that the
restriction plate can be positioned. (Refer to
Venting Configuration – Figures 14 – 16 for
recommended restriction plate positions)
(Refer to Figure 11 for proper adjustment
plate index location) ‘A’ in Figure 11 shows
the locating screw that determines the
position of the plate.
NOTE: These positions are based on lab
results and can have some variance.
Remove the screw and position the
restriction plate in the desired location.
Fasten the screw into the proper hole and
tighten. Reinstall the exhaust baffle by
setting the back edge of the baffle into the
baffle clip attached to the back wall of the
firebox. Then push the baffle against the
heat exchanger and reinstall the screw.
Reinstall the log set and ember strip as
described in the log set installation
procedure on page 27.
