Introduction
Congratulations on your purchase of a
Windsor Bay Gas-Fired Direct Vent heater.
The Windsor Bay incorporates the latest in
energy and gas technology, which will
provide you with clean, efficient heat for
years to come. The combination of natural
stone and cast iron gives the Windsor Bay
years of attractive looks and allows for
durable performance that can be maintained
with minimal care.
The Windsor Bay 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 Windsor Bay 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 is equipped with a two speed
blower fan, which turns on and off
independently of the burner flames. When
the HIGH/OFF/LO 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.

LIGHTING INSTRUCTIONS
NOTE: The gas control knobs and the piezo
ignitor are located in the lower right side
door.
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. Push in and turn gas control knob
clockwise to “OFF”. (If not previously
lit, the knob should be in this position.)
4. 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.
5. Turn gas control knob counter-clockwise
to “PILOT”.
6. Push in control knob all the way and
hold in. Immediately light the pilot with
the piezo lighter (push in and “click” the
red 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.
•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.
7. After the pilot lights, turn gas control
knob counter-clockwise to “ON”.
8. 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.
9. Shut the gas control valve access door.

HearthStone Quality Home Heating Products Inc Windsor Bay Model #8830
10
NOTE: When pressing/clicking the red
piezoelectric spark ignition button to light
the pilot, watch through the glass (front) of
the unit. Click the red 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 glass. 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.
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
T’STAT. 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.
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.
DAILY OPERATION
The Windsor Bay gas-fired heater is easily
operated by the homeowner once installed
and adjusted by a qualified service
technician. The unit can be controlled
automatically or manually. The unit is
controlled manually by setting the
ON/OFF/T’STAT switch (upper switch) in
the “ON” position, the thermostat will not
operate, and the main burner will stay on
constantly. In the “OFF” position, only the
pilot remains lit but the main burners and
thermostat will not operate. The unit is
controlled automatically via the wall-
mounted thermostat by setting the switch to
“T’STAT”. By setting the thermostat to the
desired room temperature, the unit will cycle
on and off as requested by the room
thermostat, supplied with your stove. 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 you can select the
optimum flame size for your setting and
application. During the summer, non-heating
season, switch the wall thermostat and
rocker switches to “OFF”, and turn off the
pilot. This will improve the overall
efficiency of the unit as the heat from the
pilot is not wanted in the summer. When
putting the unit back into service follow the
Lighting The Unit portion in the How To
Turn The Unit On & Off section of this
manual.

HearthStone Quality Home Heating Products Inc Windsor Bay Model #8830

When the unit is first lit, especially when
cool, it is normal to experience some
condensation on the inside of the glass
window. This condensation will burn off
within the first few minutes of operation. If
continuous condensation or water drips are
noted from any part of the unit, immediately
discontinue operation of the unit and contact
a qualified service technician.
Routine Maintenance and
Care
The Windsor Bay 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 stones, 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.
FIREBOX, PILOT, & BURNER
TUBES
The firebox, pilot & burner tubes should
receive periodic cleaning to prevent the
accumulation of dust, lint and debris.
Regularly check to insure the area around
the Windsor Bay is kept free and clear from
combustible materials, gasoline, and other
flammable vapors and liquids. Check that
the flow of ventilation air is not obstructed.
Once a year the unit and its venting
system should be inspected by qualified
service personnel to ensure that it is clean,
free of obstruction, safe, and in good
working order. If service or maintenance
is required, qualified service personnel
should perform it.

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. 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 wire from the unit to the
thermostat can be surface mounted, routed
under the floor, or through walls, etc. The
thermostat should be connected to the unit
using a maximum of 40’ (12m) of insulated
thermostat wire provided, but must not
exceed 40’ (12m) in length. Be sure to leave
a small coil of wire behind the unit so that it
can be moved out of position for servicing
and cleaning.
ELECTRICAL GROUNDING
INSTRUCTIONS
This appliance is equipped with a three-
prong (grounding) plug for your protection
against shock hazard and should be plugged
directly into a properly grounded three-
prong receptacle. Do not cut or remove the
grounding prong from this plug.
WIRING INSTRUCTIONS
The proper location of wire connections is
shown following and in Figure 4. When
making these connections, position the
thermostat wire so it extends out the side
surround panel 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. Now attach the wires in
their proper location on the fireplace, shown
in Figure 5.

Gas Supply &
Connections
¦NOTICE: A qualified technician must
connect the heater to the gas supply
and leak test the unit before it is
approved for use. Consult all codes.
¦WARNING: The unit must be installed
and connected in accordance with local
codes, or in the absence of local codes,
with the most current edition of the
National Fuel Gas Code ANSI Z223.1
(NFPA 54) or CAN/CGA B149
Installation Code.
We recommend using new black iron or
steel pipe only. Internally tinned copper
tubing can be used in some areas when
permitted by local codes. Only use pipe of
½” or greater diameter to allow full gas
volume to heater, without undue loss of
pressure. Excessive pressure loss will occur
if the pipe is too small.
The gas supply line must include a manual
shut-off valve and union so the unit can be
disconnected for servicing. Also a sediment
trap and a 1/8” N.P.T. plugged tapping must
be installed upstream of the heater. The
sediment trap is installed to prevent moisture
and contaminants from passing through the
pipe to the heater controls and burners.
Failure to install a sediment trap could
prevent the heater from operating reliably.
The 1/8” N.P.T. plugged tapping is installed
for the test gauge connection (immediately
upstream of the gas supply connection).
Damage to the valve caused by lack of a
sediment trap will not be covered by the
warranty.
We have supplied a 24” flexible stainless
steel gas line for installation convenience
and to avoid undue mechanical load on the
valve. We recommend using the flexible
line, but also refer to local code. The gas
supply line connection is made to the
flexible line in the lower rear right portion of
the Windsor Bay. Apply a thread sealant to
both male ends on the flexible gas line.
