Before commencing the FLUE KIT installation the angle of the ceiling (from the horizontal) must be determined to ensure the following requirements are adhered to in the completed installation:

• The 250mm DROP CASING TRIM UNIT and OUTER/INNER CASING COMBINATION must extend a minimum of 150mm below the underside of the ceiling. (Measured on the lower side of penetration)
• A minimum dimension of 254mm measured horizontally from the FLUE PIPE to the unprotected CEILING is achieved.
• The CEILING PLATE extends a minimum of 70mm from the 250mm DROP CASING UNIT (400mm square CEILING PLATE on a Flat Ceiling)
• A CEILING PLATE is not required if the ceiling penetration extends sufficiently to effect a minimum dimension of 450mm measured from the FLUE PIPE to the nearest surface of the ceiling.

To achieve the dimensions on Ceilings greater that 45° the 250mm DROP CASING UNIT will need to extend further that 150mm below the Ceiling and additional Ceiling shielding will be required.

1. Locate Wood Fire in its proposed position and mark a point on the ceiling that is directly above the centre of the heater’s flue outlet. Check that the heater’s location allows the OUTER CASING to clear all structural roof timbers.

2. The Sloped Ceiling Penetration Unit uses a 250mm DROP CASING TRIM UNIT and installation requires an aperture in the ceiling that allows tangential contact with the 250mm DROP CASING TRIM UNIT and 250mm OUTER CASING but in the roof cavity ensures 25mm clearance from 250mm OUTER CASING.

   To achieve the bracing required to adequately support the OUTER CASING in a Sloped
   Ceiling situation, additional timber or metal framework may be required within or below the
   ceiling cavity and external bracing required on the roof cavity but may tangentially contact
   the 250mm DROP CASING UNIT and OUTER CASING at the ceiling.

3. Cut a hole in the ceiling and roof cavity to construct an adequate support structure for the OUTER CASING and the DROP CASING TRIM UNIT.

4. Trim the DROP CASING TRIM UNIT to suit the Ceiling Slope if necessary and secure into the Ceiling support structure.

5. Position the OUTER CASING into the DROP CASING TRIM UNIT.

6. Position the 200mm BRACKETED INNER CASING into the OUTER CASING ensuring it locates onto the Internal Swage at the bottom of the OUTER CASING.

   The INNER CASING must extend a minimum of 200mm above the roof.

7. Fit an appropriate flashing to the 250mm OUTER CASING to seal onto the roofing material, Refer to the manufacturer’s recommendations for correct fitting.

8. Fit 250mm OUTER CASING SLIP EXTENSION over the OUTER CASING but do not secure until the following is checked and the FLUE PIPE is in position.

Note that AS/NZS 2918:2991 4.9.1(a) states, “the FLUE PIPE shall extend not less than 4.6m
above the top of the floor protector”.

• If the FLUE PIPE is within 3 metres of the ridge, the FLUE PIPE must protrude at least 600mm above the ridge of the roof.
• If the distance from the ridge is more than 3 metres, the FLUE PIPE must protrude at least 1000mm above roof penetration.
• The FLUE PIPE must be more than 3 metres from any nearby structure.

Additional FLUE PIPE, OUTER CASING and INNER CASING may have to be added to ensure
this requirement is met.

9. Position bottom length of FLUE PIPE (crimped end downwards) into heaters flue outlet.
10. Refer to the supplier of the heater and use flue pipe sealant if recommended.
11. Assemble FLUE PIPES together ensuring seams are straight; offsetting the seams will ensure a neat fit. Secure each joint with 3 rivets equally spaced around the joint to prevent unintentional or accidental separation. FLUE PIPES must be assembled with crimped ends down (towards heater). If using HI-THERM FLUE PIPE the protective wrapping should be left on the FLUE PIPE during installation.
12. From the roof lower FLUE PIPE through OUTER CASING into position and secure as above.
13. a) If fitting FLUE KIT with TOP SPACER BRACKET:

• Ensure the FLUE PIPE extends above the top of the OUTER CASING EXTENSION by 145mm cut either OUTER CASING EXTENSION or the FLUE PIPE to obtain this measurement.
• Fit top SPACER BRACKET to the FLUE PIPE making sure the lugs fit snugly inside OUTER CASING EXTENSION. Make sure TOP SPACER BRACKET fits hard down onto OUTER CASING EXTENSION.
• Fit CASING COVER over the FLUE PIPE and push down firmly onto TOP SPACER BRACKET.

- OR -

13. b)If fitting FLUE KIT with COMBINATION CASING COVER:

• Ensure the FLUE PIPE is either flush with or extends above the top of the OUTER CASING EXTENSION by no more than 15mm. Cut SLIP EXTENSION or FLUE PIPE to obtain this measurement.
• Push CASING COVER (with spigot inside FLUE PIPE) down onto the OUTER CASING SLIP EXTENSION. The 3 locating brackets with holes must be on the outside of the OUTER
• CASING SLIP EXTENSION and are secured using 3 rivets.

Check that a minimum dimension of 254mm measured horizontally from the flue pipe to the unprotected CEILING is achieved.
