Section 1.0 Pre-Installation Requirements
1.1 Masonry & Zero Clearance Requirements
The masonry fireplace must meet the minimum code requirements, or NFPA 211 or the equivalent for a
safe installation. Contact your local Building Inspector for requirements in your area. An inspection of
the fireplace should include the following:
1. CONDITION OF THE FIREPLACE AND CHIMNEY: Examine the masonry fireplace and
chimney prior to installation to determine that they are free from cracks, loose mortar, creosote
deposits, blockage, or other signs of deterioration. If evidence of deterioration is noted, the fireplace
or chimney should be upgraded prior to installation.
2. ZEROCLEARANCEORMETAL HEATFORMFIREPLACE: These fireplacesandchimneys
must meet the conditions above, and the factory built zero clearance fireplace must be listed. They
must be suitable for use with solid fuel. The chimney must be at least 1" (25mm) larger in diameter
to accommodate a required continuous stainless steel liner running fromthe flue collar to the top of
the chimney termination.
Only readily detachable parts that are easily replaced, such as damper parts, screens, doors, and side
and back refractory panels, are to be removed from the fireplace. These parts must be stored nearby
and available for retrofit if the insert is ever removed. Removal of any parts which render the
fireplace unfit for use with solid fuel requires the fireplace to be permanently labeled by the installer
as being no longer suitable for solid fuel until the removed parts are replaced and the fireplace is
restored to its original certified condition.
3. CHIMNEYCAPS: Mesh type chimney caps must have provision for regular cleaning, or the mesh
should be removed to eliminate the potential of plugging.
4. LINER:The chimney must have an acceptable masonry liner suitable for solid fuel, otherwise a
continuous stainless steel liner must be installed.
5. ADJACENT COMBUSTIBLES: The fireplace should be inspected to make sure that there is
adequate clearance to combustibles, both exposed combustibles to the top, side, and front as well
as concealed combustibles, in the chimney and mantel area. Your local inspector should have
information on whether older fireplaces are of adequate construction.
6. OPENING SIZE: Refer to “Suitable Fireplace Dimensions” (Sec. 2.2) for suitable size fireplace
openings.
NOTE: A METAL TAG IS PROVIDED AND IS TOBEFASTENEDTO THE BACK WALL
OF THE FIREPLACE IF THE FIREPLACE HAS BEEN MODIFIED TO ACCOMMODATE
THE INSERT.

1.2 Venting Requirements
The flue is a critical component to a satisfactory installation. Your Century insert will attain its best
performance if installed with a chimney that generates its own draft. The minimum requirement of a
flue will be the installation of a flue connector (the liner must conformto UL1777 chimney liners) from
the insert into the first flue tile of the chimney (USA), see Figure 2.3 , or a continuous stainless steel
liner (the liner must conform to the Class 3 requirements of CAN/ULC-S635) directly connected to the
flue outlet (Canada), see Figure 2.2. A continuous 6" (152mm) stainless steel liner from the top of the
chimney is the optimum system and will provide the best performance, as well as compensate for poor
draft situations caused by large cross-sectional chimneys. The insert will not work without a positive
seal in the chimney.
Chimneys constructed outside of the home, on an exterior wall, should be avoided if possible, especially
in colder climates. Outside chimneys may not draw as well and may downdraft due to the difficulty in
heating them up to operating temperature. Cooler chimneys will result in increased creosoting, less
draft, and poorer performance. Draft is proportional to overall chimney height as well as to stack
temperature. Draft can be increased by increasing chimney height, and by reducing heat loss from the
chimney through an insulated liner.
Ensure that all joints in the flue systems are tightly sealed, since any leaks will result in reduced
performance as well as a possible safety hazard.

2.1.1 Hearth Requirements
If the non-combustible hearth is flush with the floor, then the hearth must be 16”/406mm
(18”/450mm in Canada) in front of the loading door (see Figure 2.1.2). If the non-
combustible hearth is a minimum of 4” (102mm) above the floor, then the hearth can be 6”
(152mm) out from the fan housing with a 10” (254mm) floor protection (sparks) extended
beyond the hearth (see Figure 2.1.1). The non-combustible hearth, with a R-value of 0.8,
must be a minimum of 8” (203mm) on each side of the unit (Canada & USA).
Convert specification to R-value:
k-factor is given with a required thickness (T) in inches: R=1/k x T
C-factor is given: R=1/C
Example:
If the floor protector is 4” brick with a C-factor of 1.25 over 1/8” mineral board with a k
factor of 0.29 the total R-value of the system is:
4” brick C=1.25, R=1/1.25=0.8
1/8” mineral board K=0.29, R=1/0.29 x 0.125=0.431
Total R = Rbrick + Rmineral = 0.8 + 0.431 = 1.231
Total R is greater than 1.0, the system is acceptable.

2.3 Safety Information
NOTE: This appliance is not recommended for use in a home if an occupant has any respiratory
or any other related problems.
1. It is important to follow the installation and operation instructions. An improperly installed or
operated insert could result in a safety hazard or fire, or damage to the unit, which would not be
covered by the warranty. Contact local building or fire officials about restrictions and installation
requirements in your area. You should be familiar with the installation and be sure that the work is
done in accordance with this manual.
WARNING: DO NOT INSTALL THIS INSERT IN A SLEEPING ROOM.
2. Where lesser clearances are desired, consult your local authority as regulations may vary regarding
the use of clearance reducing devices. Listed wall and floor shields are available to reduce
clearances, and most building codes provide information on materials which may be used to reduce
clearances.
3. Maintain at least the minimum clearances to combustible material as specified in this manual.
Clearances are measured to the nearest part of the insert (i.e. top edge on the side). Clearances to
any combustibles, when measured directly out from the front, must be a minimum of 48" (1219mm).
4. Maintain at least the minimum floor protection for combustible floor materials as specified in this
manual. Floor protection to the front is to be measured from the fuel loading door opening.
5. Century recommends that you install a listed smoke detector or alarm in your home. Normal
operation of the insert will have no effect on the detector or alarm.
6. The insert is to be connected only to a lined masonry chimney and masonry fireplace conforming
to building codes for use with solid fuel. Do not remove bricks or mortar from the existing
fireplace when installing the insert. This insert must be connected to a code-approved masonry
chimney or listed factory-built fireplace chimney with a direct flue connector into the first
chimney liner section. The chimney size should not be less than or more than three times greater
than the cross-sectional area of the flue collar
7. Minimum chimney size is 6" (152mm) diameter. Maintain a 15' (4.5m) minimum overall height
measured from the base of the appliance. Chimneys should be inspected to check for
deterioration and to determine if they meet the minimum requirements, and be upgraded if
necessary. The chimney must extend at least 3' (914mm) above the roof and at least 2' (610mm)
above the highest point within an area of 10' (3m) of the chimney.
8. Do not use makeshift compromises during installation as they could create a safety hazard and a fire
could result.

2.4 Installation Instructions
1. Inspect the fireplace according to the safety information and fireplace requirements and have it
cleaned and/or upgraded as necessary.
2. If the installation of the unit renders the existing damper control inaccessible, it will be necessary to
either secure the damper wide open or remove it entirely. An inaccessible damper, which may close,
could cause smoke to enter the room. This creates a potential health hazard.
3. CONNECTORINSTALLATION:Aflue connector mayprovideacceptable performance,however,
we recommend the use of a chimney liner to ensure satisfactory performance. Slip connectors for
continuous liners should also be installed. Use Listed Chimney Liners – UL1777, CAN/ULC-S635.
The connector must be secured with a minimum of three screws.
4. ATTENTION INSTALLER: When positioning the unit in a fireplace opening prior to the flue
installation, install the insert into the opening until the top lip of air jacket is flush with fireplace
facing.
Figure2.2 Figure2.3
5. If lag-bolts and anchors are to be used to secure the insert, the hole locations should be marked
with the unit in place. Remove the insert and locate the anchors.
6. Remove the faceplate panels from their box and assemble according to the following
instructions.

10
2.5 Air control plate, faceplate and fan Assembly Instructions
1. Place the faceplate panels with the finished side down on a flat, soft, non-abrasive surface.
2. Assemble the faceplate trim, attaching the mitered corners with the corner brackets.
(see Figure 2.4)
3. Line up the holes of the side and top panels and secure with the four (4) screws and nuts. (see
Figure 2.5a)
4. Slide the assembled trim over the edges of the faceplate.
5. Secure trim to faceplate using six (6) "U" shaped clips. (see Figure 2.5b)

Section 3.0 Operation
3.1 Safety Information
1. This insert is designed for safe operation WHENBURNINGCORDWOOD ONLY. Altering or modifying
the unit or the installation without proper authorization will void the certification, warranty, and
safety listing, and may result in a safety hazard.
2. For safety reasons, never leave the unit unattended with the door open or ajar. An open door, and
especially a door partially open or cracked, if left for longer than required for good ignition can
potentially result in unsafe chimney temperatures, and if left unattended, hot embers or ignited fuel
may fall out of the unit. Prolonged door open operation is not necessary provided the unit has
been properly installed and dry kindling is used to start the fire.
3. Do not abuse the unit, either by over firing or by using wood or combustibles with salt content, or
harmful chemicals. Misuse is not covered by warranty.
4. Even though your Century insert has been specifically designed and tested to prevent smoke
spillage, always open the door slowly as this will minimize the likelihood of smoke spillage or a
back draft causing flame or smoke to spill into the room.
5. Never use gasoline type lantern fuel, kerosene, solvents, charcoal lighter fluid, or inflammable
liquids to start or "freshen" a fire in the insert. Keep all such liquids well away from the insert
while it is in use.
6. All insert surfaces become very hot during operation. Care is needed, especially with children, to
avoid contacting these surfaces.
7. Do not elevate the fire by means of grates, and irons or other means.
8. CAUTION:DO NOT OVER FIRE THIS HEATER.Do not burn fuel in the insert at a rate higher than that
which will cause the ember bed level to exceed half the door opening height. If burning hot fires
regularly, purchase an insert top thermometer, and do not exceed 840oF (450oC) as measured on
the cooktop. If the door handle of the insert becomes excessively hot to the touch, consider this to
be an indication of over firing. Over firing can result in a safety hazard and can permanently
damage the insert and chimney. This damage is not covered by the warranty.
9. Although the ceramic glass is extremely durable under any normal use, a few precautions are
required. Do not attempt to push logs further into the fire by using the door, as the glass may
break if it is heavily contacted by any solid object.
10. Never operate the insert with the door open, or cracked slightly open, except briefly during the
lighting operation, and during refuelling. Leaving the door open continuously could seriously

12
overheat the chimney and adjacent combustibles. Do not operate the insert ifthere is an abnormal
air leakage into the unit, such as through deteriorated gaskets or cracked or broken glass. Do not
operate the insert without a door gasket. Leakage can result in overheating, or in very airtight
homes, could possibly cause smoke spillage intothe room. Smoke may contain carbon monoxide,
which is poisonous, and in sufficient quantities is a health hazard.
11. We recommend that you have a fresh air or make up air supply for the insert. In Canada this is a
building code requirement. If this is not done, it could cause poor air quality in the home, poor
and incomplete combustion, and poor efficiency in the insert. Adequate ventilation is required to
reduce effects from room air starvation and exhaust fans.
Outside combustion air may be required if:
a. The solid-fuel-fired appliance does not draw steadily, smoke rollout occurs, fuel burns
poorly, or back-drafts occur whether or not there is combustion present.
b. Existing fuel-fired equipment in the house, such as fireplaces or other heating appliances,
smell, do not operate properly, suffer smoke roll-out when opened, or back-draft whether or
not there is combustion present.
c. Opening a window slightly on a calm (windless) day alleviates any of the above symptoms.
d. The house is equipped with a well-sealed vapour barrier and tight fitting windows and/or has
any powered devices that exhaust house air.
e. There is excessive condensation on windows in the winter.
f. A ventilation system is installed in the house.
3.2 Fuel
1. Fuel for the insert must not be stored closer than the required clearances to combustibles and not in
the space required for ash removal.
2. Your Century insert is designed to burn CORDWOOD FUEL ONLY. Do not burn coal, charcoal, or
trash in the unit. Highly flammable items such as trash may ignite creosote in the chimney,
resulting in a chimney fire. Never burn salt wood, beachwood, chemically treated wood, or wood
removed from salt water, since the deposits left will deteriorate the firebox. Damage caused by
chemicals or salt is not covered under warranty.
3. Seasoned dense wood is recommended. Wood should be air dried in a covered ventilated area for
six months to a year or more. This reduces the moisture content of the wood, resulting in better
insert performance. Wood species with a moisture content of 20% or less are ideal. Dry seasoned
wood can be distinguished from green wood by the checks or cracks in the ends.
4. Wet or green wood will tend to cause the fire to smoulder, producing large amounts of creosote.
Creosote build-up could result in a chimney fire. This wood will also prove difficult to keep burning
properly, and fires will tend to go out. Green wood produces very little heat, and sometimes causes
customers to think that the insert does not work. If you must burn wet wood, use only small
amounts mixed with dry wood.

13
5. Decayed wood or low density wood has very little energy content or heating value, and will not
burn satisfactorily for long periods of time.
An example of the energy values of some common wood fuels is given in Table 3.1 For recommended
wood sizes, refer to the specifications.
Common Heating Values of Cordwood
Hardwoods Million Btu/Cord Softwoods Million Btu/Cord
Birch 23.6 Douglas Fir 20.6
White Oak 28.3 Hemlock 17.1
Alder 17.6 Jack Pine 18.4
Table 3.1
3.2.1 Simple Wood Moisture Test
Add one large piece of wood to the top of an established fire. If it starts to burn on three sides within
one minute, it is dry and seasoned and right for burning. If it turns black and starts to burn in three
minutes, it is damp. If it turns black and does not start burning until after five minutes, it is green and
wet. If it hisses at any time, the wood is soaked and will not burn until excess moisture is boiled away.
3.3 Notes About First Firing
Before firing ensure that the room is well ventilated. Curing the paint is recommended to preserve the
best quality finish. Heating the insert too intensely on the first fire will dull and lighten the colour on
overheated areas, and cause smoke and odour to be emitted into the room. To cure the paint, the first
two fires should be burned for only about twenty minutes each.
The paint curing process will produce a light fume with an unpleasant odour. Open windows. Leave the
room if the smell is too intense. The fume is non-toxic and will disappear completely after the unit
will have been used a few times at higher firing temperatures.
Allow the insert to get warm only, but not hot, i.e. 250oF (120oC) as measured by an insert top
thermometer, then allow the insert to cool down. Light a third fire and burn it for about forty minutes to
450oF (230oC) or less. Once again cool the insert to room temperature, then operate it according to the
following instructions. This extra care will result in a more durable, and uniform finish.
3.4 Lighting A Fire
1. Place enough crumpled balls of newspaper or other paper into the insert to cover the
bottom of the firebox.
2. Place small dry kindling on the crumpled paper.
3. Place larger dry kindling on top of the small kindling.
4. Open the draft control fully to the right (located on the right side of the faceplate, Figure 3.1)

14
5. Light a fire at the bottom of the crumpled paper and close the door. If the fire tends to go out,
momentarily hold the door slightly ajar to fan the fire. As soon as the fire catches hold, close the
door.
6. Ideally the large kindling should be burned until a thick bed of red embers is obtained. At that
point, add cordwood fuel and continue to operate the draft control wide open until the fire is well
established. Once the firebox is hot, the draft control can be partially closed by moving the knob
to the left to adjust the intensity of the fire.
Use Table 3.2 to adjust the draft control to the desired burn rate:
Draft Settings
Burn Rate Draft Setting
Low Push Control to end of travel.
Medium Low Pull Control by 3/8” from closed position.
Medium High Pull Control by 3/4” from closed position
High Pull Control to end of travel.
Table 3.2
Closing the draft control down too soon will lower combustion efficiency, and may result in creosote
build-up in the chimney (which could lead to a chimney fire).
CAUTION:THE ADJUSTMENT RANGE SHOULD NOT BE ALTERED FOR INCREASED FIRING FOR ANY REASON.

3.5 Maintaining The Fire
Your Century insert will work best if a thick bed of hot embers is maintained in the bottom of the
firebox, and a minimum of two large pieces of seasoned fuel are added. Combustion efficiency is
largely related to establishing a hot ember bed, and hot firebox temperatures. The quicker the insert
and fuel get up to operating temperature, the better. A small intense fire is preferred to a large
smoldering fire, both to improve combustion efficiency and to reduce the amount of creosote emitted.
The best performance will be achieved by adding relatively small amounts of fuel to a well established
ember bed, and then operating with the air inlet control open long enough to achieve a hot fire.
Cordwood should be placed with air in between individual pieces. Use a poker to make an air channel
in the embers below the wood, this will allow air to flow under the wood for a more efficient burn.
Extended burn times can be accomplished by first operating the insert on a full load with the air inlet
controls wide open. Once the fire is well established, and the moisture has been driven out of the
wood, reduce the air control to a lower setting. The unit should then burn cleanly without smoldering.
If the fire smolders without flame, re-establish a hotter fire before moving the air control to the lower
setting. A yellow flame burning in the top of the firebox is a good indication of a clean efficiently
burning fire.
Refueling technique is important for good performance. The best efficiency and performance from
your insert can be achieved by adding partial loads of fuel and allowing them to get up to operating
temperature before adding additional fuel. Adding a large amount of fuel at one time will increase the
time required to get the fuel up to its ignition temperature, and an extended time to reach optimal
performance. When refueling, open the air control or hold the door partially open 1” (25 mm) or less,
long enough (less than 5 minutes) so that the fire has well established flames. When refueling, care is
required to ensure that fuel or embers do not fall out of the door opening.
3.6 Fan Operation
1. The fan in your wood insert is heat-activated. The insert needs to be hot before the fan
starts working. This may take up to one hour, depending on how hot the fire is.

2. You may shut the fan OFF using the variable speed control knob located on the left side of
the fan assembly..

Section 4.0 Maintenance
4.1 Care And Cleaning
Clean the insert frequently so that soot, ash and creosote do not accumulate. Do not attempt to clean the
insert, glass or door when the unit is hot. Special care must be taken with plated surfaces in order to
maintain the finish at its original brilliance. Do not use an abrasive glass cleaner which will scratch the
glass or plated finish. Use only a soft clean damp cloth on the door, since some cleaners may remove
the plating or paint.
4.1.1 Glass Cleaning and maintenance
Under normal operation the stove is designed to keep the glass clean. Glass cleaning may be required
when burning damp wood and/or when burning slow fires. Generally if the glass is not staying clean
then the unit is being under fired. Dirty glass may be self-cleaned by burning a hot fire (i.e. dry wood
and opened draft controls) for a couple of hours. Good burning techniques will result in clean glass.
Hand clean the glass only when the fire is out and the insert is cold. A light film can usually be cleaned
with paper towel and water. If heavy cleaning is required, a ceramic glass cleaner or polish is
recommended, and should be rinsed off with water for best results.
To change the glass remove the 6 glass retainers and metal frame. Remove damaged glass and install
the new one in place. Make sure you have a gasket around the replacement glass. Reinstall the metal
frame and secure it with the glass retainers.
Do not abuse the door glass by striking, slamming or similar trauma. Do not operate the stove with the
glass removed, cracked or broken.
The glass must be replaced by a genuine part only. Failure to follow instructions or use
of different material may result in property damage, bodily injury, or even death.

4.2 Ash Removal
CAUTION:Ashes can start fires, even after several days of inactivity. Never dispose of
ashes in a combustible container. Remove ashes only when the insert and
ashes are cold.
Ashes should be removed from the insert frequently. When ashes are removed, they should be placed in
a metal container with a tightly fitting lid. The closed container of ashes should be placed on a non-
combustible 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. Do not place other waste materials in the
metal ash container.
4.3 Chimney Cleaning
Regular chimney maintenance, as well as good burning practices, are required to prevent chimney fires.
The chimney and the chimney connector pipe must be maintained in good condition and be kept clean
for optimal safety. The chimney should be checked regularly for creosote build-up. Inspection and
cleaning of the chimney can be facilitated by removing the baffle.
CAUTION:OPERATION OF YOUR CENTURY INSERT WITHOUT THE BAFFLE MAY CAUSE UNSAFE AND
HAZARDOUS TEMPERATURE CONDITIONS AND WILL VOID THE WARRANTY.
Contact your local, municipal, state, or provincial fire authority for information on how to handle a
chimney fire before there is any chance that it may happen.
Creosote – Formation And Need For Removal
When wood (especially green wood) is burned without adequate heat or air supply, it produces tar and
other organic vapors (smoke), which combine with expelled moisture to form creosote. 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 makes an extremely hot fire, which could be
hazardous. Check frequently for creosote build-up. In the event of a insert or chimney component
failure, replace only with equipment that is equivalent to the original, available from your Century
dealer.
Your Century insert has been designed to reduce the amount of creosote produced. Even so, the
chimney connector pipe and chimney should be inspected at least once every two months during the
heating season to determine if a creosote build-up has occurred. If creosote has accumulated, it should
be removed to reduce the risk of chimney fire. Call a professional chimney sweep, or go to your local
Century dealer and purchase a chimney brush, and have the chimney cleaned.
