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.

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.
