INTRODUCTION
Congratulations on your purchase of a
Tucson 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 can be 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 standard
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 has been 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.
When the switch, which allows you to turn
the fan on or off and control the speed of the
fan to suit your needs, is set to “High” or
“Lo”, the fan will automatically turn on
when the stove is hot and cycle off when the
unit is no longer hot.
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 stove from
anywhere in the vicinity of the unit. If “ON”
& “OFF” are the only controls required, Kit
# 90-56912 can be used. If you would like to
control the temperature via the remote
control, use Kit # 90-56914.

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 has been 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 has been 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 31.
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.
ROUTINE MAINTENANCE
AND CARE
The Tucson requires minimal routine
maintenance and care. The unit should
always be cool and off when being cleaned.
CLEANING
›WARNING: Do not clean the unit
when hot. The unit should 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
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.

HearthStone Quality Home Heating Products Inc Tucson Model #8700

FIREBOX, PILOT, & BURNER
TUBES
The firebox should 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 31.
Check to insure a flame is burning from
each burner port. The pilot flame should be
large enough to engulf the
sensor/thermocouple as shown in Figure 2.
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 34.
Figure 2: Pilot Flame Pattern
Complete the cleaning procedure by
carefully placing the log set within the
firebox as described on page 28. Close and
fasten the front door. Turn on the gas, light
the unit and check for proper operation.
Flame patterns should look like Figure 3.
Regularly check to insure the area around
the Tucson is kept free from combustible
materials, gasoline, and other flammable
vapors and liquids. Check that the flow of
combustion and ventilation air is not
obstructed. Once a year the unit and venting
system should be inspected by qualified
service personnel to insure that they are
clean, free of obstruction, safe, and in good
working order. If service or maintenance is
required, it should be performed by qualified
service personnel.

Figure 3: Burner Flame Pattern
REPLACE THE FRONT DOOR
GASKET AS NEEDED
Your Tucson uses a 3/8” rope-type
fiberglass gasket to make a tight seal
between the door frame and the firebox. In
time, the gasket can become brittle and
compressed and should be replaced. New
gasket material is available from your
Authorized HearthStone Dealer.
1. Allow the Tucson to cool completely.
Remove the existing gasket by grasping
one end and pulling firmly.
2. Use a wire brush or the tip of a
screwdriver to clean the channel of
remaining gasket.
3. Determine the correct length of the
appropriate-sized gasket by laying it out
in the channel. Allow an extra 1 to 2”
(25-50mm), and mark the spot to be cut.
4. Cut the gasket at the marked spot with a
utility knife. Twist the ends slightly to
prevent the gasket from unraveling.
5. Apply water glass adhesive to the gasket
channel.
6. Starting at one end, press the gasket into
the channel. Insure a good joint where
the gasket ends meet before trimming
any excess. Do not overlap the gasket
ends or leave ends with ragged edges.
7. Firmly and evenly press the gasket to
seat it in its channel.
CLASS CLEANING
If operating with propane, it may be
necessary to clean the inside of the glass
occasionally. Do not use abrasive cleaners.
Do not clean the glass when hot. Allow
glass to cool and apply a window cleaning
fluid.
›WARNING: Do not operate this
appliance with the glass panel removed,
cracked, or broken. Do not subject the
door to abuse, such as striking or
slamming shut. Replacement of the glass
panel should be done by a licensed or
qualified service person.

UNPACKING AND INSPECTION
UNPACK AND INSPECT FOR DAMAGE
The Tucson is packaged by the manufacturer
to withstand shipment without damage.
However, damage can 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 two top stones and grill are
NOT cemented or otherwise permanently
fastened in place! Carefully remove and set
aside the two stones and the grill. Use the
protective wrapping material to temporarily
protect the stones from chipping and damage
while the unit is inspected and installed.
Inspect the Tucson for visible or concealed
damage. The unit should appear to be square
and true. The stones 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.
With the top stones and grill 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. Lift the stove off the
pallet and set it into place.
The decorative ceramic fiber 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 replacement logs. Otherwise, set
the logs aside until called for during the
installation.
HEARTH REQUIREMENT/FLOOR
PROTECTION
The Tucson may be placed on a non-
combustible surface or wood floor. For
placement of the Tucson on carpeting, vinyl
tile or other combustible materials, the
appliance shall be installed on a metal or
wood panel extending the full width and
depth of the appliance. Installations must
meet local codes.

HearthStone Quality Home Heating Products Inc Tucson Model #8700
15
CLEARANCE TO COMBUSTIBLES
Due to high surface temperatures, the unit
should be located out of traffic 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 14 +15.
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.
NOTE: 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 insures 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 pages
21 – 22 for positioning of the restriction
plate.
ADJUSTMENT TO RESTRICTION
PLATE
Remove the log set before adjusting
restriction plate by following the log set
removal on page 29. 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
fall out once the screw is removed. Be
careful not to drop the baffle on the burner
tube or burner tube holder. 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 fasten bolt.
Reinstall the log set and ember strip as
described in the log set installation
procedure on page 28.
