INTRODUCTION
Congratulations on your purchase of
HearthStone’s Tudor Gas-Fired Direct Vent
heater. The Tudor incorporates the latest in
balanced vent gas technology, which will
provide you with clean, efficient heat for
years to come. Combustion air comes
directly from the outside of your home to the
sealed firebox system, eliminating the
potential for annoying back drafts or other
problems associated with home
depressurization.
The Tudor 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. It includes the
new TEK Firelog technology, which is an
amazing blend of realistic flames and
glowing embers with incredible heating
characteristics.

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 Tudor is easily operated by the
homeowner once installed and adjusted by
qualified service personnel. The unit can be
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 23.
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.
Clean the area around, under, and behind the
unit on a regular basis to prevent the
accumulation of dust and lint.
The Tudor requires minimal routine
maintenance and care. It should always be
cool and off when being cleaned, or
serviced. 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, qualified service personnel should
perform it.
SERVICE CAUTION
If you believe your Tudor is not, in any way,
performing properly, immediately
discontinue operation until the unit has been
inspected and approved by qualified service
personnel. Prior to servicing the unit, turn
the valve control knob clockwise to “OFF”.
The unit should be cool prior to servicing
and cleaning. Use of any components not
supplied by HearthStone on the stove voids
all warranties. Do not substitute
components.

UNPACKING AND INSPECTION
Unpack and Inspect for Damage
The Tudor 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.
The Tudor requires a pilot shield. This
shield is shipped with the unit. Make sure
the sure the shield is installed over the
pilot with the open end is to the right
(when you are facing the front of the
stove)
Inspect the Tudor for visible or concealed
damage. The unit should appear to be square
and true. 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

HearthStone Quality Home Heating Products Inc Tudor Model #8120

found or suspected, contact your dealer for
instructions.
With the accessory box removed and set
aside, take care not to mar or chip the
enameled legs, if applicable. Have someone
help lift the stove out of the shipping box
and set it into place.
The TEK Burner and TEK Firelogs supplied
with the Tudor are contained in the
accessory box. Always use great care when
handling the decorative fire logs, as they are
fragile and subject to damage and breakage
if handled roughly. If a broken log is
encountered, contact your dealer for
replacement logs. Otherwise, set the logs
aside until called for during the installation.
INSTALLING THE TUDOR
A complete Tudor REQUIRES the
purchase of one of the following panel
kits;
91-8220010 Curio Matte (cast iron)
91-8220020 Curio Brown
91-8220059 Curio Blue/black
91-8220310 Keepsake Matte (grill + cast)
91-8220320 Keepsake Brown
91-8220359 Keepsake Blue/black
91-8220641 Heirloom Polished (stone)
91-8220653 Heirloom Brown
91-68200 Tile Insulation kit (Must be
used with self purchased
tiles) Do not paint, plaster or
finish the tiles in any way.
This may risk off gassing or a
fire.
HEARTH REQUIREMENT/FLOOR
PROTECTION
The Tudor may be placed on any surface or
wood floor, carpeting, or vinyl tile, with or
without legs. Installations must meet local
codes.
Removing the Tudor’s legs
The Tudor has the unique possibility of
having its legs removed, allowing for the
unit to rest on its base. To do this, simply
use two 7/16” wrenches or ratchets and
loosen and remove the two centermost ¼-20
bolts and nuts holding the legs on. These can
be reached the easiest from behind the unit
and should be removed prior to any other
connections have been made. Once
removed, lift the unit off the legs and set in
the desired location.
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 of the Clearances
To Combustibles section.
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.
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.

VENTING INFORMATION
VENT CONNECTION
1. An insulation blanket has been
provided and must be added to any
wall pass through (thimble) kit. This
blanket is installed inside the wall
pass through thimble and wraps
around the pipe that protrudes
through the wall. (see figure 5)The
blanket must extend the full-length,
front to back of the thimble.
2. The Tudor Direct Vent is approved
for installation only with the vent
connecting components listed;
Simpson Dura-Vent Direct Vent GS,
AmeriVent Direct, Selkirk Direct
Temp™ or Secure Vent systems.

instructions to complete the
installation.
3. Install the vent system according to
the manufacturer’s instructions.
Figure 5Wall thimble with insulation blanket
RESTRICTION PLATE
There is a vent restriction plate that adjusts
the flow rate of exhaust gases. This insures
proper flames and efficiency for the wide
variety of vent configurations. Controlling
the draft also changes the aesthetics of the
flame. The restriction plate consists of a
rotating shutter behind the starter section of
pipe and an adjustment plate with an index
hole used to hold the shutter in a fixed
position. The restriction plate has unlimited
settings. Depending on the vent
configuration, you may be required to adjust
the restriction plate position. For straight
out the back installations no adjustment
to the restrictor is necessary.
ADJUSTMENT TO RESTRICTION
PLATE
Make sure the unit is cool before touching
any part of the firebox. To adjust your
restrictor for maximum flame appearance,
loosen the Phillips head screw, found on the
upper rear right side of the stove. Spin the
indicator tab into the desired position.
Rotating counterclockwise closes the
exhaust gasses, while rotating clockwise
opens the exhaust gases. Once the desired
restriction is reached, tighten the
screw.(Refer to figure 6) There are
unlimited positions for the restriction plate,
one (1) being the lowest and three (3) being
the highest. (Refer to Venting
Configuration –Figure 6 for recommended
restriction plate positions)
NOTE: These positions are based on lab
results and can have some variance.

VENTING KIT
1. Install the 6” straight over the outer
collar.
2. Move the stove and pipe assembly
back until the 6” straight is flush to
the wall. Pull up on the pipe to
ensure that there is a ¼” per foot rise
coming out of the stove.
3. 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. Cut and frame the wall
pass through.
4. 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.
5. Place the Wall Pass through
Insulation Blanket inside of the
wall pass through as described on
page 11.
•Caution: For building with vinyl siding,
a vinyl siding standoff should be
installed between the vent cap and the
exterior wall.
6. Install the horizontal vent
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

HearthStone Quality Home Heating Products Inc Tudor Model #8120

should point up. Secure the cap to
the wall with the appropriate screws.
7. Move the stove and vent pipe into
position. Make sure the 6” vent pipe
extends into the horizontal vent cap a
minimum of 1-1/4”). Also make sure
the 6” pipe slides through the blanket
insulation that is tucked inside the
wall pass through thimble.
8. Secure the vent using the straps from
the horizontal vent termination to the
interior 6” pipe with 2 sheet metal
screws, keeping the screws close to
the wall thimble as possible. Bend or
cut the excess strapping, so that it is
not visible after the installation is
complete.

ELECTRICAL CONNECTIONS
NOTE: OPEN VALVE DOOR IN THE LOWER FRONT FOR ELECTRICAL AND GAS
CONNECTIONS.
THERMOSTAT
The ON/OFF/T’stat switch or wall mounted
thermostat controls the Tudor. We
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.
REMOTE CONTROL
There are two different optional remote
controls available for the Tudor. 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.
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
central heating system, or a nearby drafty
window.
Placement of the thermostat on an inside
wall rather than an outside wall is
preferable. Do not place the thermostat
directly behind or too close to the unit,
otherwise heat from the unit will
immediately satisfy the thermostat and turn
the unit off.
THERMOSTAT WIRING
The thermostat should be connected to the
Tudor using no more than 40’ (12 m) of the
provided insulated thermostat wire. The
thermostat wire from the Tudor to the
thermostat can be surface mounted or routed
under the floor, through walls, etc.
Be sure to leave a small coil of additional
thermostat wire behind the Tudor 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 Tudor,
then towards the thermostat.
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.

The gas supply connection is made to the
Tudor’s gas control valve in the middle of
the lower rear of the stove, using a 3/8” male
NPT fitting. The supply line should be ½”
diameter, or appropriately sized to provide a
sufficient gas supply to meet the maximum

demand of the unit without undue loss of
pressure. We recommend a flexible line to
avoid undue mechanical load on the valve
and to ease thread alignment, but refer to
local codes.
•CAUTION: Check Gas Type!
GAS SUPPLY
This appliance and its individual shutoff
valve must be disconnected from the gas
supply piping system during any pressure
testing of that system at test pressures in
excess of ½ psig. The Tudor must be
isolated from the gas supply piping system
by closing its individual manual shutoff
valve during any pressure testing of the gas
supply piping system at test pressures equal
to or greater than ½ psig.
GAS PRESSURE ADJUSTMENT
NOTE: A QUALIFIED TECHNICIAN
MUST PERFORM THIS PROCEDURE!
Once connected to the gas supply, the
supply line and manifold gas pressures must
be tested. The supply line pressure is tested,
to insure it meets the minimum gas supply
pressure as listed in the Specifications for
the type of fuel in use (natural gas or LP), by
connecting a manometer to the supply line
and adjusting the incoming pressure if
necessary to meet the required supply line
pressure as listed in specifications. The
manifold pressure tap on the gas control
valve, refer to Figure 10 for location.
FIRELOG PLACEMENT
CAUTION:Fragile! Handle log set with
care. Always wear gloves and safety goggles
while handling the log set.
Only the Firelog set supplied with the Tudor
should be placed in the firebox. Do not place
any other logs, wood logs, or other materials
in the firebox. If the log set is damaged or
broken contact your dealer for
replacement.It must be replaced with the
same approved replacement parts. These
components affect the combustion quality
and safety of the heater. The Firelog set will
last a long time, however, they will break if
subjected to rough or improper handling.
Exact positioning of the log set is required in
order to obtain a pleasing flame pattern and
efficient combustion. Incorrect log
placement may cause carbon build-up;
excess thermal stress on the log set and
stove parts, reduced efficiency, and high
levels of carbon monoxide. If the log set
does not set into the firebox exactly as
outlined, contact your dealer for assistance.
INSTALLATION OF THE FIRELOG SET
1) Open the doors on the front of the unit,
and remove the front cast and glass
assembly. To remove the front, grasp
both sides of the front cast facade, and
lift upward and then outward. The
whole piece is easily removed. Set the
front aside taking care not to chip or
scratch the enamel. Next, locate the
two rotating clips above the glass.
Rotate the clips out of the “locked”
position and tilt the top of the glass
outward. Lift the entire glass assembly
up and out.
2) Gently take the Firelogs out of the
firebox and remove the bubble wrap
from the log set. Be careful not to
damage the log set when unpacking.
There are two logs, a Front and a Rear.

3) Gently place the TEK burner in the
firebox. There are two locator tabs on
the left side and one on the right side.
Ensure these tabs find the mating slots
in the firebox sides. When installed it
should look like the figure below
4) Place the Rear Log (1) in the firebox, on
the ember burner. On the underside of
the log there is a cutout that allows the
pilot flame to reach the front burner
under the log. Align the log in the
appropriate position. It should sit as
shown in the figure below.
5) Gently place the Front Log (2) in the
firebox, on the TEK Burner. On the top
of the TEK Burner there is a cutout that
allows the Front log to rest in place. It
should sit as shown in the next figure.
6) Re-install the glass assembly by lining
up the two tabs on the bottom of the
assembly with the two slots on the
firebox. Slide the lower portion of the
glass assembly into the slots and push
the top in against the firebox. Rotate
the clips into the “locked” position. Re-
install the front cast by sliding the upper
portion onto the lip of the top and tilting
the bottom in flush with the glass
assembly. It should then be snug in
place. Make sure the glass assembly is
properly secured to the firebox before
turning the unit on. Be careful not to
chip the enamel when installing the
glass assembly or front cast.
