3.6 Flue Requirements
Standard 4.2M long, 150mm diameter Masport masonry insert flue systems or flue system that has been tested
and comply with the standard AS/NZS 2918:2001 Appendix F must be used for Rangitata ULEB burner.
If a flue exits out of the roof within 3 meters from the ridge, the outer shield shall be not less than 600mm
above the ridge. If the flue exits further than 3 meters out from the roof ridge, then it must project at least
1000mm above roof penetration. This dimension may need increasing to ensure that the top of the flue is at
least 3 meters away from the roof or other obstruction when measured horizontally.
The flue pipe shall extend not less than 4.2m above the top of the burner. Due to factors such as roof pitch,
predominant winds, nearby obstructions (i.e., trees, buildings) and fire placement, flue lengths and flue
terminations/cowls may vary. (Refer to Figure 3.3.1) Additional components may be required to complete the
installation and meet all AS/NZS 2918:2001 guidelines for flue termination.
Guidelines given in AS/NZS2918:2001 should be followed for any deviation to these standard configurations
.
Detailed instructions for roof penetrations etc. supplied along with the flue kit
must be followed closely,
including the minimum flue exit height from the top of the floor protector and the minimum exit height above
the roofline or roof ridge as detailed in the instructions.
The flue to the flue spigot and all other flue pipe joints should be sealed using firebox cement and Stainless-
Steel Rivets. Sealing all the joints is essential for achieving the desired performance of the Rangitata burner.
