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 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.  
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.  
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.  
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.  
READ THIS OWNERS MANUAL  
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.  
Operate and maintain this gas heater  
according to the instructions in this manual.  
Read this manual in its entirety.  
This  
manual has two sections, the first section is  
for the OPERATOR, and the second section is  
for the QUALIFIED SERVICE PERSONNEL only.  
HEATER MUST BE INSTALLED  
AND MAINTAINED BY QUALIFIED  
SERVICE PERSONNEL  
Verify the gas connections and venting  
systems with requirements of local, regional  
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  
or national installation codes.  
Qualified  
service personnel must inspect the gas heater  
before use and at least annually.

OWNERS 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

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.  
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

ROUTINE MAINTENANCE  
AND CARE  
The Tucson requires minimal routine  
maintenance and care. The unit should  
always be cool and off when being cleaned.  
DAILY OPERATION  
CLEANING  
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.  
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.  
During the summer non-heating season,  
switch the wall thermostat to “OFF”, and  
turn off the pilot. This will improve the

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.  
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.  
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.

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.

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.

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.

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.  
Figure 4: Minimum Venting-Mantle Clearance To  
Combustibles  
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.

plate ni dex location) ‘A’ in Figure 11 shows  
the locating screw that determines the  
position of the plate.  
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.  
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.  
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)

termination on the outside of the  
wall. Make sure both of the retaining  
straps extend through interior wall  
thimble. Before attaching the vent  
termination to the outside of the  
house, run a bead of non-hardening  
mastic around its’ outside edges, so  
as to make a seal between it and the  
wall. The arrow on the end cap  
should point up. Secure the cap to  
the wall with the appropriate screws.  
3. Install the 45º elbow over the outer  
collar. Place the elbow so that the  
twist lock end is pointing up.  
4. Install one of the 9” pipe sections  
into the elbow by fully inserting it  
and turning approximately ¼ turn  
clockwise, until the 2 sections are  
fully locked. Install the 90º elbow in  
similar fashion.  
8. Place the thimble cover onto the 90º  
elbow. Put the 9” pipe into the  
horizontal vent cap, (the vent pipe  
must extend into the horizontal vent  
cap a minimum of 1-1/4”). Move the  
stove and vent pipe into position,  
insert the 9” pipe into the 90º elbow  
and twist to lock it. Secure the straps  
from the horizontal vent termination  
to the interior pipe with 2 sheet metal  
screws, keeping screws close to wall  
thimble as possible. Bend or cut the  
excess strapping so that the thimble  
cover will fit properly. Screw the  
thimble cover to the wall.  
5. Move the stove and pipe assembly  
back until the 90º elbow is flush to  
the wall. The 9” vertical pipe should  
be parallel to the wall. Draw a circle  
around the pipe. Use the center of  
this circle as the center point of the  
10” x 10” square wall pass through.  
(It should be approximately 40-1/4”  
above the floor) Cut and frame the  
wall pass through.  
6. Place the interior wall thimble into  
the 10” x 10” wall pass through.  
Secure it with  
4
screws (not  
provided). Install the exterior portion  
of the thimble in similar fashion,  
overlapping the 2 sections.

recommend installation of the thermostat for  
more comfortable performance, however  
you may still override the thermostat by  
setting the switch to “ON”. The thermostat  
controls the unit by “calling for heat.” The  
thermostat turns the unit on when the room  
is cold, and turns the unit off once the room  
is warmed sufficiently. The thermostat is  
controlled by a 750 millivolt DC two-wire  
circuit.  
THERMOSTAT WIRING  
The thermostat should be connected to the  
Tucson using no more than 40’ (12 m) of the  
provided insulated thermostat wire. The  
thermostat wire from the Tucson to the  
thermostat can be surface mounted or routed  
under the floor, through walls, etc.  
REMOTE CONTROL  
There 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, (in the  
same way the thermostat controls the  
heater), 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.  
Installation instructions are provided with  
the kits.  
Be sure to leave a small coil of thermostat  
wire behind the Tucson so that the unit can  
be moved out of position for servicing and  
cleaning.  
Connect one of the thermostat wires to the  
gas control marked TH and the other to the  
yellow wire coming from the on/off T’stat  
switch. When making these connections,  
position the thermostat wire so that it  
extends towards the wall behind the Tucson,  
then towards the thermostat.  
THERMOSTAT PLACEMENT  
The thermostat should be placed in the same  
room or living space as the unit. Typically  
5’ (1.5m) off the floor and away from any  
influences that may cause the temperature in  
the vicinity of the thermostat to be  
unrepresentative of the room temperature in  
general. Such influences might include  
strong lighting, a heater vent from the  
At the thermostat, the wires should be  
connected to the two connection screws on  
the back of the thermostat per the  
instructions received with the thermostat.  
Take care not to over-tighten the connection  
screws and not to damage the internal parts  
of the thermostat.

ODORS AND IMPURITIES  
LIGHTING THE UNIT FOR  
THE FIRST TIME  
A heater of this type may produce odors  
during heater operation due to impurities  
that may exist in the immediate area.  
Sources of impurities can be cleaning  
solvents, paint solvents, cigarettes, smoke,  
pet hair, dust, adhesives, new carpet, and/or  
textiles. Such odors will dissipate. However,  
opening a window or otherwise providing  
additional ventilation to the area can  
alleviate the condition. If any odor persists,  
contact your dealer or an authorized service  
technician.  
WARNING: If you do not follow these  
instructions exactly, a fire or explosion  
may result causing property damage,  
personal injury or loss of life.  
CAUTION: Lighting the Tucson for the  
first time and adjustments to the unit  
should be performed by qualified service  
personnel.  
SMOKE AND FUMES WARNING  
When lit for the first time, the Tucson will  
emit some smoke and fumes. This is normal  
“off-gassing” of the paints and oils used in  
the manufacturing and assembly of the unit.  
Open windows to vent the room if  
necessary. The off gassing and fumes will  
subside after the first 10 to 20 minutes of  
operation.  
BREAK-IN WARNING  
The natural stones used in the assembly of  
the Tucson were polished using a water-  
based polishing system prior to the assembly  
of the unit. Any residue moisture in the  
stones must be dried out slowly to avoid  
damaging the stones. This is accomplished  
by adhering to the following break-in  
procedure.  
BREAK-IN PROCEDURE  
When lit the first time, the Tucson should be  
burned for no more than 15 minutes, then  
allowed to cool for 1 to 2 hours. This gentle  
warming and cooling of the unit will allow  
any residual moisture in the stones to  
evaporate slowly. Once this break-in  
procedure has been completed, the Tucson  
can be burned at will with no time  
restrictions on the length of burn.

adjustments  
may  
be  
necessary  
to  
compensate for variations in gas pressure,  
altitude, and other factors particular to each  
installation.  
PREPARE FOR LIGHTING  
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.  
VARIABLE OUTPUT CONTROL  
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.  
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.  
AIR SHUTTER  
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.  
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.  
INITIAL ADJUSTMENTS

To determine if the air shutter needs  
adjustment, it is necessary to view the flame  
pattern with the variable output control knob  
at its highest setting. Allow the unit to  
operate for 10 minutes to allow the entire  
unit to reach temperature and for the flame  
pattern to stabilize. Generally, the more air  
(open shutter) in the mixture, the bluer the  
flame. Less air (closed shutter) results in a  
more yellow flame, but too little air will  
result in incomplete combustion, low  
efficiency and a dirty burn. There are two  
simple guidelines to aid in determining the  
correct flame pattern:  
4. Push in and turn gas control knob  
clockwise to “OFF”. (If not previously  
lit, the knob should be in this position.)  
5. Wait (5) five minutes to clear out any  
gas. If you then smell gas, STOP! 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 smell gas  
immediately follow the What To Do If  
You Smell Gas! warning on the cover of  
this Manual. If you do not smell gas,  
proceed to the next step.  
6. Turn gas control knob counter-clockwise  
to “PILOT”.  
1. if the flame at the base of the logs is  
completely blue, the air shutter may  
be open too far;  
2. if the flame is dirty or licks the top of  
the stove, the air shutter may be  
closed too far.  
7. Push in control knob all the way and  
hold in. Immediately light the pilot with  
the gas lighter (push in and “click” the  
piezoelectric spark ignitor button several  
times until lit). Continue to hold the  
control knob in for about 20 seconds  
after the pilot is lit. Release the knob and  
it will pop back out. Pilot should remain  
lit. If the pilot goes out, repeat the  
operation.  
Some conditions cannot be corrected

an  
adjustment must be made to the gas supply

part of the installation or adjustment of this  
unit unless technically qualified to do so.  
·
If knob does not pop out when released,  
stop, shut off the gas supply to the heater  
and immediately call a qualified service  
technician or gas supplier.  
·
If the pilot will not stay lit after several  
tries, turn the gas control knob “OFF”  
and call a qualified service technician or  
gas supplier.  
LIGHTING INSTRUCTIONS  
NOTE: The gas control knobs and the piezo  
ignitor are located behind the control valve  
access door, under the front of the unit.  
1. STOP! Read the What To Do If You  
Smell Gas! Warning (on the cover of  
this manual).  
2. Set the on/off/T’stat switch or thermostat  
to the “OFF” position.  
3. Unplug the fan accessory, if so  
8. After the pilot lights, turn gas control  
knob counter-clockwise to “ON”.  
9. If the ON/OFF/T’stat switch is set to  
“ON”, the stove should now be lit. If the  
thermostat (or remote) has been  
installed, set the ON/OFF/ T’stat switch  
to “T’stat” and turn the thermostat (or  
remote) to “ON”. Then set the desired  
temperature.

10. Shut the gas control valve access door.  
11. Plug in the fan accessory, if so equipped.  
12. If T’stat was selected, set thermostat to  
“ON” and set desired temperature  
setting. Normally, if T’stat position was  
selected, the main burner is cycled on  
and off by the thermostat or the “on/off”  
switch located on the bottom of the  
thermostat body.  
TO TURN OFF GAS TO APPLIANCE  
1. Set the thermostat to the “OFF”  
position or turn the ON/OFF/T-  
STAT switch to the “OFF”  
position.  
2. If shutting the unit off for the  
non-heating season, turn the gas  
control knob fully clockwise to  
the “OFF” position. Do not force  
the knob to turn.  
NOTE:  
When  
pressing/clicking  
the  
piezoelectric spark ignition button to light  
the pilot, watch through the glass (front) of  
the unit. Click the ignitor button until a  
flame is visible at the pilot. Once the pilot is  
lit, continue to press on the gas control knob  
for another 20 seconds, then release.  
Ascertain that the pilot is still lit by looking  
through the front door. If lit, then turn the  
gas control knob fully counter-clockwise to  
the “ON” position. If the pilot fails to light,  
or if it went out due to a premature release  
of the gas control knob while pressed in the  
“PILOT” position, wait 60 seconds for the  
Interlock to release. Then repeat the lighting  
process as described in this section of the  
manual.  
AIR SHUTTER ADJUSTMENTS  
The air shutter is adjustable while the stove  
is burning by loosening the adjusting nut  
located under the rear right hand corner of  
the stove. This nut is hot and should not be  
touched. Use only metal tools for this  
adjustment.  
Moving the nut toward the front of the stove  
increases the air and moving the nut toward  
the back of the stove decreases the air.  
Tighten the nut after making adjustment.  
The air shutter is factory set and only a  
qualified gas technician should make  
adjustments.  
Once the pilot has been lit, the gas control  
knob has been turned to the “ON” position,  
and the ON/OFF/T’stat switch has been  
turned to “ON”, the main burners should  
light immediately. If you would like to use  
the thermostat and it has been installed,  
switch the ON/OFF/T’stat switch to  
thermostat. Turn the thermostat to "ON" and  
set it to a higher position so that it "calls" for  
heat in order to turn light the main burners  
(i.e. turns the unit on). Note that the  
thermostat controls the on/off cycling of the  
main burners, but the pilot remains lit  
regardless of the thermostat setting. The  
only way to turn the pilot off is to turn the  
gas control knob fully clockwise to the  
“OFF” position.  
Note: Very little movement is needed to  
substantially change the burn and flame  
patterns.

BURNER FLAME APPEARANCE  
PILOT ADJUSTMENT  
Once the unit is lit, observe the flame  
pattern and adjust as necessary. Also, a  
periodic visual check of the burner flame  
should be performed. The burner flames can  
be adjusted by means of the air shutter. To  
determine if the burner flame needs  
adjustment, it is necessary to view the flame  
pattern with the variable output control knob  
at its highest setting (turn fully clockwise).  
Allow the unit to operate for 10 minutes  
enabling the entire unit to reach temperature  
and for the flame pattern to stabilize. The  
flame pattern should be similar to the one  
shown in Figure 24. There are several  
guidelines to aid in determining if the flame  
pattern is correct:  
The pilot light is preset by the manufacturer  
and should not need adjustment. The pilot  
light flame should be large enough to engulf  
the thermopile and thermocouple located  
next to the pilot, but not so large as to create  
excessive noise or consume excessive gas.  
(Refer to figure 23) However, it can be  
adjusted by means of the pilot light  
adjustment screw located on the gas control  
valve. Open the valve door to access the  
pilot adjustment screw. Note that the pilot  
flame must engulf the thermopile so that the  
thermopile can generate sufficient  
milli-voltage (325 to 500-mv) to power the  
milli-volt gas control valve. The flame on  
the pilot should look like Figure 23.  
Controlling the Tucson by the wall-mounted  
thermostat may become erratic, nonexistent,  
or the unit may go out, if the pilot flame is  
too small or misdirected away from the  
thermopile.  
1. The flame should not be dirty, smoky,  
sooty, or lick the top of the stove.  
2. The flame should not rise off of the  
burner tube, called “lifting”.  
3. Flames should not impinge heavily on  
the log set. They should “fit” through the  
pre-formed spaces designed in the log  
set.  
Figure 23 Pilot Flame Pattern  
WARNING  
The control has an interlock device. If the  
stove has been lit, it will not relight  
immediately. 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  
sec.). The gas control knob is designed to  
be operated by hand. Do not use any tools  
during this operation.

MAINTENANCE AND  
PILOT & BURNER FLAMES  
CARE  
With the decorative ceramic fiber logs out of  
the firebox, fasten the front shut and  
momentarily light the unit according to  
lighting instructions described in the How  
To Turn the Unit On & Off section of this  
manual. Check to ensure a flame is burning  
from each burner port. The pilot flame  
should be large enough to engulf the  
thermocouple and thermopile as shown in  
Figure 23.  
The Tucson requires minimal routine  
maintenance and care.  
The unit should  
always be cool and off when being serviced.  
WARNING:  
Do not substitute  
materials. For replacement parts, or for  
information about parts or service,  
contact your local HearthStone dealer.  
CLEANING  
WARNING: DO NOT CLEAN THE  
UNIT WHEN IT’S HOT!  
NOTE: Do not operate the unit for more  
than 1-2 minutes without the log set in  
place. Turn the unit off by setting the  
thermostat to “OFF”, and turning the gas  
control valve off. Allow the unit to cool.  
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 or wax based cleaners or  
polishes is not recommended due to the  
potential for discoloration when the residue  
of the cleaners or polishes is exposed to  
heat.  
Check and clean any burner ports that were  
not burning properly or at all. Clean burner  
ports using a soft brush or vacuum cleaner.  
If the pilot flame height needs adjustment it  
should be adjusted by a qualified service  
technician as described in the Initial  
Adjustments section of this manual.  
Complete the cleaning procedure by  
carefully placing the log set within the  
firebox as described in the Log Set  
Information section of this manual. Fasten  
the front door. Turn on the gas, light the unit  
and check for proper operation. Flame  
patterns should look like Figure 24.  
Regularly check to insure the area around  
the Tucson is kept free and clear from  
combustible materials, gasoline, and other  
flammable vapors and liquids. Check that  
the flow of combustion and ventilation air is  
not obstructed.  
FIREBOX  
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, remove the front and  
carefully remove the decorative ceramic  
fiber log set (after it has cooled), taking care  
not to damage the logs or chip the enamel  
cast iron. Clean the firebox, burner tube, and  
pilot assembly and carefully vacuum the  
entire surface of the log set. Take care to  
thoroughly vacuum the ports (holes) along  
the top of the burner tubes and the pilot  
assembly.
