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 con-
sidering. 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.

30 operating instructions
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!!
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 opera-
tion of your Catalytic combustor and draft control.
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 the catalytic by-pass control fully.
(Handle pulled out) and open primary air
damper to the full open position
2. The unit is equipped with log andirons to aid
in keeping fuel from sliding, rolling towards
the glass.
Open firebox door and build a small fire using
paper and dry kindling on the firebrick hearth,
DO NOT USE A GRATE. Secure door on the
firebox and wait a few minutes for a good up-
draft 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.
3. With the catalytic by-pass damper still in the
fully open position, 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.
4. The temperature in the stove and the gases
entering the combustor must reach between
5000F - 7000F for catalytic activity to start. From
the start up of a cold stove, a medium to high
firing rate must be maintained for 30 min. This
ensures that the stove, catalyst and fuel are all
stabilized at proper operating temperatures.
Even though it is possible to have tempera-
tures at 6000F within minutes after a fire has
been started, if the fire is allowed to die down
immediately it may go out or the combustor
may stop working. Once the combustor starts
working, heat generated in it by burning the
smoke will keep it working. During re-fueling
and rekindling of the cool fire, or a fire that has
burned down to the charcoal phase, operate
the stove at a medium to high firing rate for
about 10 minutes to ensure that the catalyst
reaches operating temperatures.
WARNING: Never build a roaring fire
in a cold stove. Always warm your
stove up slowly!
5. When re-fueling, always open by-pass control,
load fuel, then wait for at least 10-15 minutes
before closing the by-pass. Reason for the
10-15 min. is the fresh fuel and the opening
of the door will cause the catalyst to drop in
temperature as well as the moisture within the
wood which is the first thing to be released.
6. 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.
Left - Open Right - Closed
In - Closed Out - Open
Catalyst Bypass 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 closed. The CI2600/HI400 unit has
a secondary draft system that continually allows
combustion air to the induction ports at the top of
the firebox, just in front of the catalytic combustor.
Draft is the force which moves air from the appli-
ance 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 damage the
catalytic combustor. Inadequate draft may cause
back puffing into the room and plugging of the
chimney or catalyst.
7. 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.
8. Do not place anything on the stove top during
the curing process. This may result in damage
to your paint finish.
9. 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.
10. 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.
11. Some cracking and popping noises may be
experienced during the heating up process.
These noises will be minimal when your unit
reaches temperature.
12. 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.
13. 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.
CAUTION: 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.
14. Green or wet wood is not recommended for
your unit. If you must add wet or green fuel,
open the draft control fully until all moisture has
been dispersed by the intense fire. Once all
moisture has been removed, the draft control
may be adjusted to maintain the fire.
15. 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.
16. The controls of your unit or the air supply pas-
sages should not be altered to increase firing
for any reason.
WARNING
Fireplace Inserts 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.

17. 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, catalytic thermostat is ac-
tive, then your flue is clean and your exhaust is
clean. Burn the stove hot enough to keep your
glass clean and catalytic combustor ,you won't
need to clean your flue as often.
CAUTION
1. Never use gasoline, gasoline type lantern fu-
els, 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.
HOT WHILE IN OPERATION. KEEP
CHILDREN, CLOTHING AND
FURNITURE AWAY. CONTACT MAY
CAUSE SKIN BURNS.
During constant use, ashes should be removed
every few days. Please take care to prevent the
build-up of ash around the start-up air housing
located inside the firebox, under the loading door lip.
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. Always
leave 1 to 2 inches of ash in the bottom of the firebox.
This helps in easier starting and a more uniform
burn of your fire.
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. Other waste should
not be placed in the ash container.
The fan unit must not be turned on until a fire has
been burning for at least 30 minutes and the unit
is hot enough. As well, after each fuel loading the
fan must be shut off until 30 minutes has elapsed.
To operate fan automatically, push switch on side of
fan housing to "Auto" and second switch to either
"High" or "Low" for fan speed. The automatic tem-
perature sensor will engage the blower when the
unit is at temperature and will shut off the blower
once the fire has gone out and the unit has cooled
to below a useful heat output range.
To manually operate the fan system, push the first
switch to "Man" and second switch to either "high"
or "Low". This will bypass the sensing device and
allow full control of the fan. Switching from "Auto" to
"Manual" or "High" to "Low" may be done at any time.
To achieve maximum efficiency and performance,
operate the fan in the low speed when the air control
is not more than ¼’’ open from its lowest setting. See
draft control instructions for operation of air control.
When the appliance is cool it is important to clean
in and around the fan. Always ensure areas on the
hearth are clean and ashes, debris etc. are not
pushed towards the bottom of the fascia. Always
brush and clean debris away from the unit, not
towards.
When wood is burned slowly, it produces tar and
other organic vapors, which form creosote when
combined with moisture. The creosote vapors
condense in the relatively cool chimney flue of a
slow-burning fire. As a result, creosote residue
accumulates on the flue lining. When ignited,
this creosote can make an extremely hot fire.
For wood-burning heaters, reference to the for-
mation and removal of creosote buildup in the
chimney connector and chimney as follows (the
inspection frequency "once every two months'
stated below may be a shorter time period at
the manufacturer's or private labeler's options):
"Creosote - Formation and Need for Removal
The chimney connector and chimney should be
inspected at least once every two months during the
heating season to determine if a creosote buildup
has occurred.
If creosote has accumulated it should be removed
to reduce the risk of chimney fire.
Removal of your insert for cleaning purposes is
usually not required if a proper installation has been
done. In the event that removal is required, be sure
not to damage any parts needed for re-installation.
In most cases removal and replacement of the
baffle system should allow full access for cleaning.
WARNING: In case of chimney fire:
1. Close draft control
2. Call the Fire Department
Store wood under cover, such as in a shed, or cov-
ered with a tarp, plastic, tar paper, sheets of scrap
plywood etc., as uncovered wood can absorb water
from rain or snow, delaying the seasoning process.
DO NOT USE CHEMICALS FOR
FLUIDS TO START FIRE.

SAFETY GUIDELINES & WARNINGS
1. Burn insert with draft control wide open for
about 45 minutes every morning during burning
season. This helps to prevent creosote deposits
within the heating system.
2. Burn insert with draft control wide open for about
10 - 15 minutes every time you add fresh wood.
This allows the wood to achieve the charcoal
stage faster and burns up any wood vapors
which might otherwise be deposited within the
system.
3. Only burn seasoned wood! Do not burn wet
or green wood. Seasoned wood that has been
dried at least one year must be used.
4. A small hot fire is preferable to a large smoul-
dering one that can deposit creosote within the
system.
5. Check the chimney at least twice a month during
the burning season for creosote build-up.
6. Have chimney system and unit cleaned by
competent chimney sweeps twice a year
during the first year of use and at least once
a year thereafter or when a significant layer
of creosote has accumulated (3mm / 1/8" or
more) it should be removed to reduce the
risk of a chimney fire.

9. Do not connect this unit to a chimney flue serving another appliance.
10. Do not use grates, 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 seasoned hard-
woods, as compared to softwoods or to green or freshly cut hardwoods.
14. 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.
15. Do not operate with broken glazing.
16. The controls of your unit or the air supply passages should not be altered
to increase firing for any reason.
17. If you burn the unit too slowly or at too low a setting your unit will not be
operating as efficiently as it can. An easy rule of thumb says that if your
glass is clean, catalytic thermostat is active, then your flue is clean and
your exhaust is clean. Burn the stove hot enough to keep your glass clean
and catalytic combustor, you won't need to clean your flue as often.
DO NOT BURN:
• Treated wood
• Coal
• Garbage
• Cardboard
• Solvents
• Colored Paper
• Trash
• Salt drift wood
• Cut lumber, plywood, mill ends.
Burning treated wood, garbage, solvents, colored paper or trash may result
in release of toxic fumes and may poison or render ineffective the catalytic
combustor. Burning coal, cardboard, or loose paper can produce soot, or
large flakes of char or fly ash that can coat the combustor, causing smoke
spillage into the room, and rendering the combustor ineffective.
CAUTION: DO NOT CONNECT TO, OR USE IN CONJUNC-
TION WITH ANY AIR DISTRIBUTION DUCT WORK UN-
LESS SPECIFICALLY APPROVED FOR SUCH
INSTALLATION.
DO NOT BURN GARBAGE OR FLAMMABLE LIQUIDS SUCH
AS GASOLINE, NAPTHA OR ENGINE OIL. SOME FUELS
COULD GENERATE CARBON MONOXIDE AND ARE
VERY DANGEROUS.

CATALYTIC COMBUSTOR (PART # 106-534)
ACHIEVING AND MAINTAINING CATALYST LIGHT-OFF:
There are some obvious signs of trouble that your inspection may reveal.
The temperature in the stove and the gases entering the combustor must be
raised to between 500F to 700F for catalytic activity to be initiated. During the
start up of a cold stove a medium to high firing rate must be maintained for
about 30 minutes. This ensures that the stove, catalyst and fuel are all sta-
bilized at proper operating temperatures. Even though it is possible to have
temperatures at 600F within minutes after a fire has been started, if the fire
is allowed to die down immediately it may go out or the combustor may stop
working. Once the combustor starts working, heat generated in it by burning
the smoke will keep it working. During re-fueling and rekindling of the cool
fire, or a fire that has burned down to the charcoal phase, operate the stove
at a medium to high firing rate for about 10 minutes to ensure that he catalyst
reaches operating temperatures.
CATALYST MONITORING: It is important to periodically monitor the opera-
tion of the catalytic combustor to ensure that it is functioning properly and to
determine when it needs to be replaced. A non-functioning combustor will
result in a loss of heating efficiency, and an increase in creosote and emis-
sions. Following is a list of items that should be checked on a periodic basis.
• Combustors should be visually inspected at least three times during the
heating season to determine if physical degradation has occurred. Actual
removal of the combustor is not recommended unless more detailed in-
spection is warranted because of decreased performance. If any of these
conditions exist, refer to Catalyst trouble shooting section of this owner’s
manual.
• A good combustor is designed to withstand approximately 12,000 hours of
continuous use. This will translate into five to ten years of use, depending
on the length of your heating season and how often you use your stove.
Proper maintenance will increase the combustor’s effectiveness and pre-
vent many problems. Inspect your combustor before each heating season,
and during the season if your stove’s performance seems to change.
• You can get an indication of whether the catalyst is working by compar-
ing the amount of smoke leaving the chimney when the smoke is going
through the combustor and catalyst light – off has been achieved, to the
amount of smoke leaving the chimney when the smoke is not routed (by-
pass open) through the combustor.
CATALYTIC COMBUSTOR CLEANING:
Method #1
A vacuum cleaner may be used, but never use high pressured air to
blow the cells free of any build-up. This can damage the cell walls. Any cell
blockage can be removed with the use of a pipe cleaner or a cotton swab
as well.
Method #2
Should the combustor’s cells become covered with fly-ash, use a paint-
brush or soft-bristled brush and dust the combustor gently.
Never use anything abrasive to clean the combustor.
Method #3
Normally the catalytic combustor requires little or no maintenance, it gen-
erates such high temperatures and therefore is basically self-cleaning.
However, should the combustor become covered with soot or creosote, it
is possible to burn the accumulation off by opening the bypass and build-
ing a hot fire.
Once the hot fire is created, close the bypass halfway and burn for 30 to 60
minutes with the bypass left in this position. Never use cleaning solvents
to clean it.
Check and clean the combustor, if necessary, before each burning season
and inspect the flue system for any signs of creosote buildup.
A clean flue helps prevent chimney flue fires.

Step 1: Light the stove in accordance with instructions within this
manual.
Step 2: With smoke routed through the catalyst (by-pass closed)
go outside and observe the emissions leaving the chim-
ney.
Step 3: Engage the bypass mechanism and move to by-pass
open position. And again observe the emission leaving
the chimney. Significantly more smoke should be seen
when the smoke is not routed through the combustor (by-
pass open). Be careful not to confuse smoke with steam.
ACHIEVING PROPER 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 damage the catalytic combustor. Inadequate draft may
cause back puffing into the room and plugging of the chimney or catalyst.

tighter seal.
To remove a shim, loosen the 2 bolts to create clearance behind catch. Place
a screwdriver in the slot of the shim and slide out. Retighten bolts.
Note: Keep the shims - they may be required in the future when the gasket
is replaced.
