“This wood heater has a manufacturer set minimum low burn rate that must not be altered. It is against federal regulations to alter this
setting or otherwise operate this wood heater in a manner inconsistent with operating instructions in this manual.” Failure to follow
the manual details can lead to smoke and CO emissions spilling into the home. It is recommended to have monitors in areas that are
expected to generate CO such as heater fueling areas.

“This manual describes the installation and operation of the Regency I2450M wood heater. This heater meets the 2020 U.S. Environmental Pro-
tection Agency’s cord wood emission limits for wood heaters. Under specific test conditions this heater has been shown to deliver heat at rates
ranging from 14,200 Btu/hr. to 34,660 Btu/hr.” Efficiency is determined using the B415 method resulting in lower and higher heat values. This heater
generates the best efficiency when operated using well-seasoned wood and installed in the main living areas where the majority of the chimney is
within the building envelope. "
It is against federal regulation to operate this wood heater in a manner inconsistent with operating instructions in this manual, or if elements are
deactivated or removed."
CAUTION: BURN UNTREATED WOOD ONLY. OTHER MATERIALS SUCH AS WOOD PRESERVATIVES, METAL FOILS, COAL, PLASTIC,GARBAGE,
SULPHUR OR OIL MAY DAMAGE THE HEATER.
"This heater is designed to burn natural wood only. Higher efficiencies and lower emissions generally result when burning air dried seasoned hard-
woods, as compared to softwoods or to green or freshly cut hardwoods."
DO NOT BURN:
• Treated wood • Lawn clippings or yard waste • Manure or animal remains
• Coal • Materials containing rubber including tires • Saltwater driftwood or other previously salt
water saturated materials
• Garbage • Materials containing plastic • Unseasoned wood
• Cardboard • Waste petroleum products , paints or paint thinners or asphalt
products
• Paper products, cardboard, plywood or par-
ticle board. The prohibition against burning
these materials does not prohibit the use
of fire starters made from paper, cardboard,
saw dust, wax and similar substances for the
purpose of starting a fire in a wood heater.
• Solvents • Materials containing asbestos
• Colored Paper • Construction or demolition debris
• Trash • Railroad ties
Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke.
The authority having jurisdiction (such as Municipal Building Department, Fire Department, Fire Prevention Bureau, etc.) should be con-
sulted before installation to determine the need to obtain a permit.
This unit must be connected to either a listed factory built chimney suitable for use with solid fuels and conforming to, ULC629 in Canada or UL-
103HT in the United States of America. or code approved masonry chimney with flue liner.
I2450M is tested and certified to ULC-S628-93 (R1997) and UL1482-2011 (R2015).

Chimney Specifications
Before installing, check and clean your chimney
system thoroughly. If in doubt about its condition,
seek professional advice. Your Regency Insert is
designed for installation into a masonry fireplace
that is constructed in accordance with the require-
ments of "The Standard for Chimneys, Fireplaces,
Vents, and Solid Fuel Burning Appliance", N.F.P.A.
211, the National Building Code of Canada, or
the applicable local code requirements.
The appliance, when installed, must be electri-
cally grounded in accordance with local codes or,
in the absence of local codes, with the National
Electrical Code, ANSI/NFPA 70, or the Canadian
Electrical code, CSA C22.1.
Regency Inserts are designed to use either a
5.5" (140mm) or 6" (152mm) flue.
Installation into a Masonry
Fireplace
Regency Inserts are constructed with the high-
est quality materials and assembled under strict
quality control procedures that insure years of
trouble free and reliable performance.
It is important that you read this manual thor-
oughly and fully understand the safe instal-
lation and operating procedures. The more
you understand the way your Regency Insert
operates, the more enjoyment you will experi-
ence from knowing that your unit is operating
at peak performance.
Before Installing
Your Insert
1. Please read this entire manual before you
install and use your new wood insert. Failure
to follow instructions may result in property
damage, bodily injury or even death. Install
and use only in accordance with manufac-
turer’s installation and operating instructions.
2. Check your local building codes - Building
Inspection Department. You may require
a permit before installing your insert. Be
aware that local codes and regulations
may override some items in the manual.
WARNING: Careless installation is the
major cause of safety hazard. Check all
local building and safety codes before
installation of unit.
3. Notify your home insurance company that
you plan to install a fireplace insert or hearth
heater.
4. Your fireplace insert is heavy and requires
two or more people to move it safely. The
insert can be badly damaged by mishandling.
5. If your existing fireplace damper control will
become inaccessible once you have installed
your Regency Insert, you should either
remove or secure it in the open position.
6. Inspect your fireplace and chimney prior
to installing your insert to determine that it
is free from cracks, loose mortar or other
signs of damage. If repairs are required,
they should be completed before installing
your insert. Do not remove bricks or mortar
from your masonry fireplace.
7. Do not connect the insert to a chimney
system servicing another appliance or
an air distribution duct.
When referencing installation or connec-
tion to masonry fireplaces or chimneys,
the masonry construction must or shall be
code complying.
In Canada this fireplace insert must be
installed with a continuous chimney liner
of 5.5" (140 mm) or 6" (152 mm) diameter
extending from the fireplace insert to the
top of the chimney. The chimney liner must
conform to the Class 3 requirements of CAN/
ULC-S635 or CAN/ULC-S640, Standard for
Lining Systems for New Masonry Chimneys.
Draft is the force which moves air from the appliance
up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors.
Too much draft may cause excessive temperatures
in the appliance and may cause damage. An uncon-
trollable burn or excessive temperature indicates
excessive draft. Inadequate draft may cause back
puffing into the room and plugging of the chimney.
Inadequate draft will cause the appliance to leak
smoke into the room through appliance and chim-
ney connector joints. Ensure the heater is installed
in areas that are not too close to neighbors or in
valleys that would cause unhealthy air quality or
nuisance conditions.
Optional Flue Connector Kit
The Straight Flue Adaptor (Part #846-504) shown
here, may be used to produce a secure connection
between your flue connector and the insert collar.
Detailed installation instructions are included with
the kit.
The following may also be purchased separately if
required to complete the install:
846-506 6" Flue Adapter 30 degree
846-508 6" Flue Adapter 45 degree
948-412/P 6" Flue Offset Adapter (offsets back 4")
846-527 Flue Connector Kit
Straight adaptor shown with flue
connector kit
In the U.S.A., a 5.5 inch (140 mm) or 6 inch
(152 mm) diameter, stainless steel,full height
chimney liner that meets type HT (21000F)
requirements per UL 1777 must be installed.
The full liner must be attached to the insert
flue collar and to the top of the existing ma-
sonry chimney.

WARNING: This fireplace may have been altered
to accommodate an insert. It must be returned
to its original condition before use as a solid fuel
burning fireplace.
1. When installed in a factory built fireplace, a
full stainless steel rigid or flexible flue liner is
mandatory, for both safety and performance
purposes. When a flue or liner is in use, the
insert is able to breathe better by allowing a
greater draft to be created. The greater draft
can decrease problems such as, difficult start-
ups, smoking out the door, and dirty glass.
2. In order to position the flue liner, the existing
rain cap must be removed from your chimney
system. In most cases the flue damper should
also be removed to allow passage of the liner.
3. In most cases opening the existing spark
screens fully should give enough room for the
insert installation. If it does not, remove and
store.
4. If the floor of your fireplace is below the level
of the fireplace opening, adjust the insert's
levelling bolts to accommodate the difference.
When additional shimming is required, use
non-combustible masonry or steel shims.
5. Measure approximately the alignment of the
flue liner with the position of the smoke outlet
hole on the insert to check for possible offset. If
an offset is required, use the appropriate offset
adaptor in your installation.
Installation Into a Factory
Built Fireplace
Regency inserts are constructed with the highest
quality materials and assembled under strict quality
control procedures that ensure years of trouble free
and reliable performance.
It is important that you read this manual thoroughly
and fully understand the installation and operating
procedures. Failure to follow instructions may result
in property damage, bodily injury or even death. The
more you understand the way your Regency Insert
operates, the more enjoyment you will experience
from knowing that your unit is operating at peak
performance.
Draft
Draft is the force which moves air from the appliance
up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors.
Too much draft may cause excessive temperatures
in the appliance and may cause damage. An uncon-
trollable burn or excessive temperature indicates
excessive draft. Inadequate draft may cause back
puffing into the room and plugging of the chimney.
Inadequate draft will cause the appliance to leak
smoke into the room through appliance and chim-
ney connector joints. Ensure the heater is installed
in areas that are not too close to neighbors or in
valleys that would cause unhealthy air quality or
nuisance conditions.
Requirements for Installing Solid-fuel
Inserts in Factory-built Fireplaces
1. A permit may be required for installations, final
approval is contingent of the authority having
local jurisdiction. Consult insurance carrier, local
building, fire officials or authorities ha-ving juris-
diction about restrictions, installation inspection,
and permits.
2. Inspect the existing fireplace and chimney for
any damage or flaws such as burnouts, metal or
refectory warping.
3. Inspection to a minimum of NFPA 211 Level II is
recommended. All repairs must be made prior to
installing an insert. The fireplace must be structur-
ally sound and be able to support the weight of
the solid-fuel insert.
4. The factory-built chimney must be listed per UL
127 or ULC 610-M87 for all installations. Install
thermal protection as per this appliance listing
requirements.
5. A full height 5.5 inch (140 mm) or 6 inch (152 mm)
diameter stainless steel full height listed chimney
liner must be installed meeting type HT (2100oF)
requirements per UL 1777 (USA) or ULC S635
with ''0'' clearance to masonry (Canada). The full
liner must be attached to the insert flue collar and
to the top of the existing chimney.
6. The flue liner top support attachment must not
reduce the air flow for the existing air-cooled
chimney system. Reinstall original factory-built
chimney cap only.
7. To prevent room air passage to the chimney cav-
ity of the fireplace, seal either the damper area
around the chimney liner or the insert surround.
Circulating air chamber (i.e. in a steel fireplace liner
or metal hearth circulatory) may not be blocked.
The air flow within and around the fireplace shall
not be altered, blocked by the installation of the
insert (i.e. not louvers or cooling air inlet or outlet
ports may be blocked by the insert or the insert
surround).
8. Means must be provided for removal of the insert
to clean the chimney flue.
9. Inserts that project in front of the fireplace must
be supplied with appropriate supporting means.
10. Installer must mechanically attach the supplied
label to the inside of the firebox of the fireplace
into which the insert is installed.
WARNING
Fire Risk.
When lining air-cooled factory-built
chimneys:
- Run chimney liner approved to
UL 1777 Type HT requirements
(2100oF)
- Reinstall original factory-built chim-
ney cap ONLY
- DO NOT block cooling air openings
in chimney
- Blocking cooling air will overheat

insert is to be installed is prohibited, except that the
damper may be removed to accomodate a direct-
connect starter pipe or chimney liner.
- External trim pieces which do not affect the op-
eration of the fireplace may be removed providing
they can be stored on or within the fireplace for
reassembly if the insert is removed.
- The permanent metal warning label provided in
the component pack must be attached to the back
of the fireplace, with screws or nails, stating that the
fireplace may have been altered to accomodate the
insert, and must be returned to original condition
for use as a conventional fireplace.
- If the hearth extension is lower than the fireplace
opening, the portion of the insert extending onto
the hearth must be supported.
- Manufacturer designed adjustable support kit can
be ordered from your dealer.
- Final approval of this installation type is contingent
upon the authority having jurisdiction.

Installing Your Insert
Your insert is very heavy and will require two or three
people to move it into position. The insert can be
made a little lighter by removing the cast iron door
by opening it and lifting it off its hinges. Be sure to
protect your hearth extension with a heavy blanket
or carpet scrap during the installation.

Faceplate And Trim installation
Wood Insert
Faceplate & Trim Assembly
WOOD INSERT
I2500M
Your Faceplate kit contains:
1 Set Faceplate panel (top, left & right)
1 Set Tr i m (top, left, right)
2 pcs. insulation
4 spring nuts
4 1" screws
8 washers
2 screws - black
2 corner trim clips
Note: The Digital Monitor Operating Door tool Bracket
and tool holder are supplied with the insert.
Prior to sliding your insert into its final position and
attaching the connector or liner pipe, the faceplate must
be installed as follows:
1) Slide the spring nuts (supplied) over the slots in
the insert’s side convection panels (the spring nuts
may need to be squeezed with a pair of pliers first,
to help them stay in position).
2) Screw the side faceplate panels, (item A in the
diagram) one to each side. See diagram 1.
3) Using the top panel (item B - see diagram 1)
as a gauge, check that the side panels are within
approximately 1/4" of the overall width. If the
difference is greater than this, use the supplied
washers to attain the required width.
4) The unit may now be slid into final position and
attached to the connection system.
5) Once connection is made, the insulation strips
should be installed between the insert faceplates
and the fireplace face.
6) The faceplate top may now be installed (with insula-
tion strip behind) by aligning its brackets with the
top flange on the side shields and the angle iron
bar on the insert top.
7) The faceplate trim may be installed to the edge of
the faceplate at this time. To permanently mount the
trim, drill two 5/32" diameter holes through the trim
and side panels and screw the trim to the panels
using the gold plated screws provided.
Note: It may be easier to install the insulation, faceplate
top and faceplate trim with the unit pulled slightly
away from the fireplace face. If this is done, be
very careful not to disturb the connector when
shifting the unit to its final position.
8) Now that your insert is installed, check once more
that all the clearances from the unit to any combus-
tible materials are correct as listed earlier.

Seasoned Wood
Whether you burn wood in a fireplace, stove or insert, good quality firewood is the key to convenience,
efficiency and safety. Wet wood and pieces that are not the right size and shape for your wood burner
can be frustrating, burn inefficiently and deposit creosote that can fuel a dangerous chimney fire. Good
planning, seasoning and storage of the firewood supply are essential to successful wood burning.
• Stack the wood in separate rows in an open location where the summer sun can warm it and
breezes can carry away the moisture. Do not stack unseasoned wood tightly in an unvented
storage area.
• Do not allow firewood to lie on the ground for more than a couple of days before stacking.
Mould and rot can set in quickly.
• Stack the wood up off the ground on poles, lumber rails or pallets.
• The top of the pile can be covered to keep off rain, but do not cover the sides.
Softer woods like pine, spruce and poplar/aspen that is cut, split and stacked properly in the early spring
maybe be ready for burning in the fall. Extremely hard woods like oak and maple, and large pieces of
firewood, may take a minimum of a full year to dry enough. Drying may also take longer in damp climates
There are a few ways to tell if wood is dry enough to burn efficiently. Use as many indicators as possible
to judge the dryness of the firewood your are considering. Here are ways to judge firewood moisture.
• Using a moisture meter, select the species of fuel and then penetrate the pins into a split piece.
Ideal moisture and seasoned firewood should be less than 20% moisture content.
• Checks or cracks in the end grain can be an indication of dryness, but may not be a reliable
indicator. Some wet wood has checks and some dry wood has no checks.
• The wood tends to darken from white or cream colour to grey or yellow as it dries.
• Two dry pieces banged together sound hollow; wet pieces sound solid and dull.
• Dry wood weighs much less than wet wood.
• Split a piece of wood. If the exposed surface feels damp, the wood is too wet to burn.

How to Light & Maintain a
Wood Stove Fire
WARNING: To build a fire in ignorance
or to disregard the information con-
tained in this section can cause serious
permanent damage to the unit and void
your warranty!!
Operating
Instructions
With your unit now correctly installed and safety
inspected by your local authority, you are now ready
to start a fire. Before establishing your first fire, it
is important that you fully understand the operation
of your draft control.
WARNING
Fireplace Stoves equipped with doors
should be operated only with doors fully
closed. If doors are left partly open, gas
and flame may be drawn out of the fireplace
stove opening, creating risks from both
fire and smoke.
First Fire
When your installation is completed and inspected
you are ready for your first fire.
THIS UNIT IS DESIGNEDTO BURN SEASONED
CORDWOOD ONLY. COAL AND BRIQUETTES
ARE NOT APPROVED.
1. Open firebox door and build a small fire using
paper and dry kindling on the firebrick hearth,
DO NOT USE A GRATE. CAUTION: DO NOT
BUILD FIRETOO CLOSETO GLASS. Secure
door on the firebox and wait a few minutes for
a good updraft in the flue to establish the fire.
(Leaving the door slightly open will help your
fire start more rapidly.)
CAUTION: Never leave unit unattended
if door is left open. This procedure is for
fire start-up only, as unit may overheat
if door is left open for too long.
2. Add two or three seasoned logs to your fire.
Form a trench in the ash bed to allow air to
reach the rear of the firebox prior to closing
the door. Build fire slowly.
WARNING: Never build a roaring fire in
a cold stove. Always warm your stove
up slowly!
3. During the first few fires, keep the combustion
rate at a moderate level and avoid a large fire.
Only after 5 or 6 such fires can you operate the
stove at its maximum setting, and only after the
metal has been warmed. Always build up the
fire slowly.
4. For the first few days, the stove will give off an
odour from the paint. This is to be expected as
the high temperature paint becomes seasoned.
Windows and/or doors should be left open to
provide adequate ventilation while this tem-
porary condition exists. Burning the stove at a
very high temperature the first few times may
damage the paint. Burn fires at a moderate
level the first few days.
5. Do not place anything on the stove top during
the curing process. This may result in damage
to your paint finish.
6. During the first few days it may be more difficult
to start the fire. As you dry out your firebrick
and your masonry flue, your draft will increase.
7. For those units installed at higher elevations or
into sub-standard masonry fireplaces, drafting
problems may occur. Consult an experienced
dealer or mason on methods of increasing your
draft.
8. Some cracking and popping noises may be
experienced during the heating up process.
These noises will be minimal when your unit
reaches temperature.
Left - Open Right - Closed
Outward - Open Inward - Closed
Side Draft Control
Draft Control
Both the primary and air wash drafts are controlled
by the control slide located on the front left side of
the unit (when facing the unit). To increase your draft
- slide to the left to open, and to decrease - slide to
the right to close. The I2450M unit has a secondary
draft system that continually allows combustion
air to the induction ports at the top of the firebox.
Draft is the force which moves air from the appliance
up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors.
Too much draft may cause excessive temperatures
in the appliance. Inadequate draft may cause back
puffing into the room and plugging of the chimney.
9. Before opening your door to reload, open the
by-pass damper fully for approximately 10 to 15
seconds until the fire has been re-established.
This will minimize any smoking (spilling) back
into the room. After loading wood and front door
closed, close the by-pass damper, push rod in.
10. All fuel burning appliances consume oxygen
during operation. It is important that you
supply a source of fresh air to your unit while
burning. A slightly opened window is sufficient
for the purpose. If you also have a fireplace
in your home, a downdraft may be created by
your Regency Stove causing a draft down your
chimney. If this occurs, slightly open a window
near your unit.
WARNING: If the body of your unit,
or any part of the chimney connector
starts to glow,you are over firing. Stop
loading fuel immediately and close
the draft control until the glow has
completely subsided.
11. If you have been burning your stove on a low
draft, use caution when opening the door. After
opening the damper, open the door a crack, and
allow the fire to adjust before fully opening the
door.
12. The controls of your unit or the air supply pas-
sages should not be altered to increase firing
for any reason.
13. If you burn the unit too slowly or at too low a set-
ting your unit will not be operating as efficiently
as it can. An easy rule of thumb says that if your
glass is clean, then your flue is clean and your
exhaust is clean. Burn the stove hot enough to
keep your glass clean, you won't need to clean
your flue as often.

20 operating instructions
Fan Operation
Automatic
To operate the fan - turn on the rheostat.
This will allow the fan to turn on as the stove has
come up to operating temperature. It will also shut
the fan system off after the fire has gone out and
the unit cooled to below a useful heat output range.
Operate the fan in the low speed position when
burning in the LOW-MED LOW heat output ranges
and operate in the high setting for MED-HIGH to
HIGH heat outputs.
Route power cord to either left or right behind unit.
Ash Disposal
During constant use, ashes should be removed
every few days.
Ashes should be placed in a metal container with
a tight-fitting lid. The closed container of ashes
should be placed on a noncombustible floor or on
the ground, well away from all combustible materials,
pending final disposal. If the ashes are disposed of
by burial in soil or otherwise locally dispersed, they
should be retained in the closed container until all
cinders have thoroughly cooled.
Safety Precautions
1. Do not allow ashes to build up to the loading
doors! Only remove ashes when the fire has
died down. Even then, expect to find a few hot
embers.
2. Please take care to prevent the build-up of ash
around the start-up air housing located inside
the stove box, under the loading door lip.
Safety Guidelines
and Warnings
CAUTION: Do not use chemicals AS fluids to
start fire.
1. CAUTION: Never use gasoline, gasoline type
lantern fuels, kerosene, charcoal lighter fuel, or
similar liquids to start or ‘freshen up’ a fire in your
heater. Keep all such liquids well away from the
heater while it is in use.
2. Keep the door closed during operation and
maintain all seals in good condition.
3. Do not burn any quantities of paper, garbage, and
never burn flammable fluids such as gasoline,
naptha or engine oil in your stove.
4. If you have smoke detectors, prevent smoke
spillage as this may set off a false alarm.
5. Do not overfire heater. If the chimney connector,
flue baffle or the stove top begin to glow, you
are over firing. Stop adding fuel and close the
draft control. Over firing can cause extensive
damage to your stove including warping and
premature steel corrosion. Over firing will void
your warranty.
6. Do not permit creosote or soot build-up in the
chimney system. Check and clean chimney at
regular intervals. Failure to do so can result in
a serious chimney fire.
7. Your Regency stove can be very hot. You may be
seriously burned if you touch the stove while it is
operating, keep children, clothing and furniture
away. Warn children of the burn hazard.
8. The stove consumes air while operating, provide
adequate ventilation with an air duct or open a
window while the stove is in use.
9. Do not connect this unit to a chimney flue serving
another appliance.
10. Do not use grates or andirons or other methods
for supporting fuel. Burn directly on the bricks.
11. Open the draft control fully for 10 to 15 seconds
prior to slowly opening the door when refuelling
the fire.
12. Do not connect your unit to any air distribution
duct.
13. This heater is designed to burn natural wood
only. Higher efficiencies and lower emissions
generally result when burning air dried sea-
soned hardwoods, as compared to softwoods
or to green or freshly cut hardwoods.
14. In the event of component failure, replace parts
with only Regency listed parts.
15. Warning: do not abuse glass door such as
striking or slamming shut.
CAUTION: HOT WHILE IN
OPERATION. KEEP CHILDREN,
CLOTHING AND FURNITURE
AWAY. CONTACT MAY CAUSE SKIN
BURNS.
16. Do not store any fuel closer than 2 feet from
your unit. Do not place wood, paper, furniture,
drapes or other combustibles near the appliance.
17. CAUTION: Do not operate with broken glazing.
