“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 I2500 catalytic equipped wood heater. This heater meets the 2020 U.S. En-
vironmental Protection 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 17,178 Btu/hr. to 42,995 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. "This wood heater contains a catalytic combustor, which needs periodic inspection and replacement for
proper operation.
It is against federal regulation to operate this wood heater in a manner inconsistent with operating instructions in this manual, or if the
catalytic element is 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 CATALYST
CAUTION: CATALYTIC COMBUSTOR IS FRAGILE--HANDLE WITH CARE.
The performance of the catalytic device or its durability has not been evaluated as part to this certification.
"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

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.
I2500 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 fire-
place that is constructed in accordance with the
requirements of "The Standard for Chimneys,
Fireplaces, Vents, and Solid Fuel Burning Ap-
pliance", 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.
A continuous liner is required from the unit to
the cap.
Requirements for Installing
Solid-fuel Inserts in Factory-built
Fireplaces.
1. The insert must be tested and meet the
requirements of UL 1482 (U.S.) and or ULC
S628 (Canada) when tested in a masonry
fireplace built per ULC S628.
2. The factory-built fireplace must be listed per
UL 127 or ULC S610.
3. Clearances obtained from the masonry fire-
place tests are also relevant for installation
in factory-built fireplaces.
4. Installation must include a full height listed
chimney liner type HT requirements (2100
degree F.) per UL 1777 (U.S.) or ULC
S635 (Canada). The liner must be securely
attached to the insert flue collar and the
chimney top, a continuous full liner.
5. Means must be provided to prevent room
air passage to the chimney cavity of the fire-
place. This may be accomplished by sealing
the damper area around the chimney liner,
or sealing the fireplace front.
6. Alteration of the fireplace in any manner is
not permitted with the following exceptions;
a.  externaltrimpieceswhichdonota󰀨ect

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

INSTALLATION INTO A
MASONRY FIREPLACE
The insert must be installed as per the requirements
of your local inspection authority. A full flue liner
is required.
A full flue liner is a stainless steel rigid or flexible
liner pipe which is routed from the insert outlet collar
to the top of the chimney.
Flush Inserts
Full Flue Liner
(No Cleanout Required)
The use of this connection method listed on this
page not only increases the safety of your insert
by directing the hot gases up the flue, but will also
help increase the unit's efficiency and decrease
creosote deposits in the chimney.
When a connected 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.
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 un-
controllable 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.
STEP-BY-STEP
INSTALLATION INTO A
FACTORY BUILT
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 a proper stainless
steel unit available with the chimney liner.
6. Once the above items have been checked, slide
your insert into position after first positioning
the flue liner and offset if required. (Re-install
rain cap at completion of installation).
NOTE: Refer to "Requirements for Installing
Solid-fuel Inserts in Factory-built Fire-
places" section for the requirements
for installing solid fuel inserts in factory
built fireplaces.
Prior to sliding your insert into its final position and
attaching the connector or liner pipe, the faceplate
side panel plates must be installed as follows:

The flue baffle system located in the upper area
of the firebox is removable to make cleaning your
chimney system easier. The baffles must be
installed prior to your first fire. Smoke spillage
and draft problems may occur if the baffles are
improperly positioned. Check the position of the
baffles on a regular basis as they can be dislodged
if too much fuel is forced into the firebox.
GLASS REPLACEMENT
Your Regency stove is supplied with 5 mm Neoceram
ceramic glass that will withstand the highest heat that
your unit will produce. In the event that you break
your glass by impact, purchase your replacement
from an authorized Regency dealer only.
Remove the door from the stove and remove the
screws securing the glass retainer. Position the glass
in the door, make sure that the glass gasketing will
properly seal your unit, and replace the retainer,
it should rest on the gasket not the glass. Tighten
securely, but do not wrench down on the glass as
this may cause the glass to break.
