INSTALLATION
CHIMNEY
SPECIFICATIONS
Before installing, check and clean your chimney
system thoroughly. If in doubt about its condi-
tion, seek professional advice. Your Regency
Insert is designed for installation into a masonry
replace 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) ue.
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
replace built per ULC S628.
2) The factory-built replace must be listed per
UL 127 or ULC S610.
3) Clearances obtained from the masonry re-
place tests are also relevant for installation
in factory-built replaces.
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 ue collar and the
chimney top.
5) Means must be provided to prevent room
air passage to the chimney cavity of the
replace. This may be accomplished by
sealing the damper area around the chimney
liner, or sealing the replace front.
6) Alteration of the replace in any manner is not
permitted with the following exceptions;
a. external trim pieces which do not a󰀨ect
the operation of the replace may be
removed providing they can be stored
on or within the replace for re-assembly
if the insert is removed.
b. the chimney damper may be removed
to install the chimney liner.
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 manufactur-
er’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 replace insert or hearth
heater.
4) Your replace insert is heavy and requires
two or more people to move it safely. The
insert can be badly damaged by mishan-
dling.
5) If your existing replace damper control
will become inaccessible once you have
installed your Regency Insert, you should
either remove or secure it in the open posi-
tion.
6) Inspect your replace 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 replace.
7) Do not connect the insert to a chimney
system servicing another appliance or
an air distribution duct.
7) Circulating air chambers (i.e. in a steel re-
place liner or metal heat circulator) shall not
be blocked.
8) Means must be provided for removal of the
insert to clean the chimney ue.
9) Inserts that project in front of the replace
must be supplied with appropriate supporting
means.
10) Installer must mechanically attach the supplied
label to the inside of the rebox of the replace
into which the insert is installed.
In order for a solid-fuel insert to be certied for use
in factory-built replaces, the above information
must be clearly stated in the installation manual and
appropriate markings. Final approval is contingent
on the authority having jurisdiction.

INSTALLATION
Clearance diagram for Installations
Side and Top facing is a maximum of 1.5" thick.
Floor protection must be non-combustible, insula-
tive material with an R value of 1.1 or greater.
* Hearth thickness of 0.5" with k value = 0.84",
r value = 0.6 or greater.
** A non-combustible mantel may be installed
at a lower height if the framing is made of
metal studs covered with a non-combustible
board.
** Max. mantle depth is 10" (254mm).
Thermal oor protection is not required if the unit is
raised 3.5" minimum (measured from the bottom of
the stove). However, standard ember oor protec-
tion is required. It will need to be a non-combustible
material that covers 16" (406 mm) in the US and
18" (450 mm) in Canada to the front of the unit and
8" (200 mm) to the sides.
If the unit is not raised, thermal oor protection
required is 18" (450 mm) in the US and Canada.
All oor protection must be non-combustible (i.e.,
metals, brick, stone, mineral ber boards, etc.) Any
organic materials (i.e. plastics, wood paper prod-
ucts, etc.) are combustible and must not be used.
The oor protection specied includes some form
of thermal designation such as R-value (thermal
resistance) or k-factor (thermal conductivity).
MASONRY AND FACTORY BUILT FIREPLACE CLEARANCES
The minimum required clearances to combustible materials when installed into a masonry or factory built replace are listed below.

HOW TO DETERMINE IF ALTERNATE
FLOOR PROTECTION MATERIALS ARE ACCEPTABLE
The specied oor protector should be 3/8"
(18mm) thick material with a K - factor of
0.84.
The proposed alternative is 4" (100mm) brick
with a C-factor of 1.25 over 1/8" (3mm) mineral
board with a K-factor of 0.29.
Step (a):
Use formula above to convert specication
to R-value.
R = 1/k x T = 1/0.84 x .75 = 0.893.
Step (b):
Calculate R of proposed system.
4" brick of C = 1.25, therefore
Rbrick = 1/C = 1/1.25 = 0.80
1/8" mineral board of k = 0.29, therefore
Rmin.bd. = 1/0.29 x 0.125 = 0.431
Total R = Rbrick + Rmineral board =
0.8 + 0.431 = 1.231.
Step (c):
Compare proposed system R of 1.231 to
specied R of 0.893. Since proposed system
R is greater than required, the system is
acceptable.

FLUE CONNECTOR
BRACKET
Package contains: 3 brackets and 6 screws.
These brackets are to be used to hold the ue
liner (not supplied) to the Insert and keep the
connection. The brackets are screwed into the
top of the Insert in the pre-punched holes and
then screwed into the ue liner.
INSTALLATION INTO A
MASONRY FIREPLACE
The insert must be installed as per the require-
ments of your local inspection authority. Three
methods of ue connection are acceptable in
most areas in the US, however a full ue liner
is required in Canada.
1) Positive ue connection, where a large
blocking plate and a short connector pipe
is used.
2) Direct ue connection, where a smaller
blocking plate and a connector pipe to the
rst ue liner tile is used.
3) Full ue liner, where a stainless steel rigid
or exible liner pipe is routed from the insert
outlet collar to the top of the chimney.
Regency highly recommends the use of a full
liner as the safest installation and provides the
most optimum performance. Your retailer should
be able to help you decide which system would

3a) Full Flue Liner
(No Cleanout Required)
be the best for your application.
Note: A clean-out door is sometimes
required, by your inspector, to be
installed when either the Positive ue
connection or Direct ue connection
method is used.
The use of one of the connection methods listed
on this page not only increases the safety of your
insert by directing the hot gases up the ue, but
will also help increase the unit's e󰀩ciency and
decrease creosote deposits in the chimney.
When a connected ue 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, di󰀩cult start-ups,
smoking out the door, and dirty glass.
STEP-BY-STEP
INSTALLATION INTO A
FACTORY BUILT
FIREPLACE
1) When installed in a factory built replace, a
full stainless steel rigid or exible ue liner
is mandatory, for both safety and perform-
ance purposes. When a ue 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, di󰀩cult start-ups, smoking out the door,
and dirty glass.
2) In order to position the ue liner, the exist-
ing rain cap must be removed from your
chimney system. In most cases the ue
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 oor of your replace is below the
level of the replace opening, adjust the
insert's levelling bolts to accommodate the
di󰀨erence. When additional shimming is
required, use non-combustible masonry or
steel shims.
5) Measure approximately the alignment of
the ue liner with the position of the smoke
outlet hole on the insert to check for pos-
sible o󰀨set. If an o󰀨set 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 rst po-
sitioning the ue liner and o󰀨set if required.
(Re-install raincap at completion of installa-
tion).
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 replaces.
