  • Page 5: Section 1.0 Pre-Installation Requirements

    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.

  • Page 6: Venting Requirements

    1.2 Venting Requirements The flue is a critical component to a satisfactory installation. Your insert will attain its best performance if installed with a flue that generates its own draft. The minimum venting requirement will be the installation of a flue connector from the insert into the first tile of the chimney (see Figure 2.3). If you are using a masonry chimney, it is important that it be built in compliance with the specifications of the National Building Code or other applicable standard having jurisdiction.

  • Page 7: Section 2.0 Installation

    Section 2.0 Installation 2.1 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.

  • Page 8: Installation Instructions

    2.2 Installation instructions Inspect the masonry fireplace according to the safety information and fireplace requirements and have it cleaned and/or upgraded as necessary. 2.3 Compliance of the masonry fireplace Where the masonry fireplace opening is 6 ft (0.56 m ) or larger, the hearth extension shall extend at least 20'' (508 mm) in front of the facing material and at least 12'' (305 mm) beyond each side of the fireplace opening.

  • Page 9: The Masonry Fireplace's Draft Control System

    2.4 The masonry fireplace's draft control system If the fireplace's draft control system is to remain in the masonry fireplace, it must be locked open for access of the chimney liner or removed entirely. If you remove draft control system from the masonry hearth, you will need to install the metal plate (27009), supplied with the owner’s manual kit, indicating that the masonry hearth has been modified.

  • Page 10: Positioning The Unit

    2.6 Positioning the unit In addition to ensuring compliance of the masonry fireplace hearth extension (see Compliance of the masonry fireplace in Section 2.3), it is necessary to have a floor protection made of non-combustible materials that meets the measurements specified in table FLOOR PROTECTION (see Section 2.7). To determine the need to add a floor protection (D) beyond the hearth extension, you must do the following calculation using the data in Table Data for floor protection calculation of this section: D = B - (A - C).
  • Page 11 If a non-combustible material floor protection needs to be added in front and level with the hearth extension masonry fireplace (see Figure 2.6a), an R factor equal to or greater than 1.00 is required. If the extension of the masonry hearth is raised at least 4" from the floor protection (see Figure 2.6b), a non-combustible material without an R factor is sufficient.
  • Page 12 The use of an R value is convenient when more than one material is going to be used in the hearth extension to cover the combustible surface. This is because R values are additive, whereas K values are not. To find the corresponding R factor to use for some selected materials, please see Table Thermal characteristics of common floor protection materials in this section.
  • Page 13 The more extended the insert, the greater the heat transfer to the room. You may install the insert within the minimum and maximum extension listed in the table below (value (C)) or any position in between. The position chosen will depend on your own preference for most installations, your current configuration, the compliance with the preceding installation instructions and compliance with the building code requirements.

  • Page 16: Connector Installation

    2.8 Connector installation A masonry flue connector may provide acceptable performance (Figure 2.8a); however, we recommend the use of a chimney liner (rigid or flexible) to ensure satisfactory performance (Figure 2.8b). To ensure an optimal draft, we also strongly recommend adding a minimum of 18” rigid liner between the roof flashing and the rain cap.

  • Page 17: Chimney Liner Installation

    2.8.1 Chimney liner installation To the chimney liner to the insert’s flue outlet, you have two options: A) Install the chimney liner starter adapter, provided with the chimney liner. Follow the chimney liner starter adapter manufacturer's instructions. B) You can get from your dealer a liner fixation system (AC02006), sold separately. Follow the installation instructions provided with the liner fixation system.

    2.9 Faceplate Assembly Instructions (Faceplate kit must be ordered separately). Note: The illustrations may vary from one model to another, but the method of assembly remains the same. Remove the faceplate panels from its box and the faceplate extension secured between the firebox and the convection air jacket.
  • Page 19 Insert the superimposed brackets (F) and (G) with the screws (H) in the groove of each decorative trim (I), (J) and (K) (see DETAIL B). Align the corners of the angled side of each trim, and then tighten the screws (H) to secure the trims. Align the trim assembly with the left and right edge of the faceplate and slowly slide it down over the faceplate.
  • Page 20 Once the faceplate is assembled, align the notches, located at the top of each side of the faceplate opening, with the top of the insert and slide the assembly toward the front of the insert (see DETAIL A). Center the insert into the fireplace opening. Adjust its height using the leveling bolts on each side of the convection air jacket box until the faceplate is properly seated on the floor of the...

  • Page 21: Section 3.0 Operation

    Section 3.0 Operation 3.1 Safety Information This insert is designed for safe operation . Altering or modifying URNING ORDWOOD the unit or the installation without proper authorization will void the certification, warranty, and safety listing, and may result in a safety hazard. For safety reasons, never leave the unit unattended with the door open or ajar.

  • Page 22: Fuel

    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 overheat the chimney and adjacent combustibles. Do not operate the insert if there is an abnormal air leakage into the unit, such as through deteriorated gaskets or cracked or broken glass.

  • Page 23: Simple Wood Moisture Test

    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 3.2 For recommended wood sizes, refer to the specifications.

  • Page 24: Lighting A Fire

    3.4 Lighting A Fire Place enough crumpled balls of newspaper or other paper into the insert to cover the bottom of the firebox. Place small dry kindling on the crumpled paper. Place larger dry kindling on top of the small kindling. Open the draft control fully to the right (located on the right side of the faceplate, Figure 3.4) Light a fire at the bottom of the crumpled paper and close the door.
  • Page 25 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). AUTION DJUSTMENT ANGE HOULD LTERED NCREASED IRING EASON DAMPER OPERATION CLOSED OPENED Figure 3.4...

  • Page 26: Maintaining The Fire

    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.

  • Page 27: Section 4.0 Maintenance

    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.

  • Page 28: Ash Removal

    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.
