4.5.3 SP6 Internal Models – 100mm Drainage Waste Vent (DWV) flue
All SP6 internal model heaters are supplied with an Level Invert Taper (LIT) fitting and flue connection to unit is with
100mm Drain Waste Vent pipe (DWV to AS/NZS 1260).
Flue shall be installed in accordance with the following:
• Exit heater with a minimum 300mm straight run of 100mm DWV flue before the first elbow.
• All flue joints shall be adequately sealed to prevent condensate leakage.
• Ensure there is continual fall back to the flue outlet on the heater from flue termination point.
• Flue shall be removable from the heater to allow for repairs and/or removal of the appliance.
• Flat side of the LIT (not tapered side) must be positioned so it is always the lowest part of the fitting or the
closest point to ground.
Note: If a lay-down kit is used, the LIT must be rotated to ensure the flat side of LIT fitting is closest to ground (Diagram 5).
