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.
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. By following a few simple safety
precautions and by performing minimal
maintenance, the unit will remain appealing while
providing years of quality performance.

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 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 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 22.
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 is 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 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. The
inner refractory panels are wrapped and are in the
firebox. Always use great care when handling the
decorative fire logs and inner panels, as they are
fragile and subject to damage and breakage if
handled roughly. If a broken log or panel is
encountered, contact your dealer for replacements.
Otherwise, set the logs and panels aside until called
for during the installation.

VENTING INFORMATION
VENT CONNECTION
1. An insulation blanket is provided and must be
added to any wall pass through (thimble) kit.
This blanket is installed inside the wall pass
through the 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. Use the
following instructions along with the pipe
manufacturer’s instructions to complete the
installation.
3. Install the vent system according to the
manufacturer’s instructions.
Figure 5: Wall 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)

INSTALLATION INSTRUCTIONS FOR
THE STANDARD HORIZONTAL
TERMINATION MINIMUM 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 buildings 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 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.

GAS CONNECTIONS
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.
REFRACTORY PANEL
INSTALLATION
CAUTION: Fragile! Handle panel set with care.
Always wear gloves and safety goggles while
handling.
Only the panel set supplied with the Tudor should
be placed in the firebox. Do not place any other
materials in the firebox. If the panel 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
panel set will last a long time; however, they will
break if subjected to rough or improper handling.
Exact positioning of the panel set is required in
order to obtain a pleasing flame pattern and efficient
combustion. Incorrect placement may cause carbon
build-up; excess thermal stress on the panels and
stove parts, reduced efficiency, and high levels of

carbon monoxide. If the panel set does not fit into
the firebox exactly as outlined, contact your dealer
for assistance.
PANEL PLACEMENT
CAUTION: Fragile! Handle panel set with care.
Always wear gloves and safety goggles while
handling.
1) Remove the cast top of the stove by lifting it
straight up and off the unit.
2) Remove front façade by lifting it up and off the
front.
3) Using a flat tip screwdriver, lift and rotate up the
two retaining clips on the top of the firebox and
remove the glass front.
4) Carefully remove the bubble wrapped panels
from the firebox, unwrap and inspect for
damage or missing parts. Contact your dealer if
necessary.
5) The panels are very fragile – do not force them
into position!
6) Insert the rear panel into the firebox, right edge
first, rotate panel flat against rear wall and
lower into place behind the pilot assembly.
Center the panel and push it back as far as
possible.
7) Insert the right panel into the firebox, partially
insert the long edge into the groove inside the
right side of the firebox opening, raise the panel
about two inches so it will clear the pilot
assembly and rotate it into place against the
side wall while seating it in the groove. The
panel will not clear the rear panel if it is not
inserted fully into the groove. Slide the panel
down onto its supporting flange.
8) Insert the upper panel into the firebox and place
its lower edge on top of the rear panel. The
right side panel will now hold the top panel up in
position in the firebox.
9) Insert the left panel into the firebox, place it on
the support flange and carefully insert the long
edge partially into the groove inside the left side
of the firebox. Rotate the panel into place while
seating it in the groove.
10) Ensure the side and rear panels are firmly
seated, and then move the top panel into its
final position. There should be no large gaps
between the upper and lower panels.
REMOVAL OF PANEL SET
CAUTION: The panels retain heat and can be very
hot! Allow 2 to 3 hours after pilot light is turned off
before handling.
To remove the panel set, follow the Installation of
Panel Set instructions in the reverse order.
LOG SET INSTALLATION
CAUTION: Fragile! Handle log set with care.
Always wear gloves and safety goggles while
handling the log set.
Only the Log 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 Log 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 fit
into the firebox exactly as outlined, contact your
dealer for assistance.
LOG SET PLACEMENT
1) If not already so, 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. 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 logs out of the accessory box
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.
Take care to avoid damaging the left side

refractory panel, when inserting the burner.
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:
Front log
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 and
top cast.
