6.2 EXTERNAL FLUE TERMINAL CLEARANCES
6.2.1 Installation of Flue Terminal
The flue outlet socket can be found behind an installer instruction label. The flue terminal must be ordered separately
when SP4UN is installed externally (Part No. B021385).
Remove the label and insert the flue terminal firmly into the flue outlet socket in the correct orientation to ensure the
flue gases are expelled away from the house (refer to Diagram 12).

The flue terminal must be ordered separately when an SP4UN model is installed externally
(Part No. B021385).
The flue terminal must always be installed before starting the heater.
Heaters that are installed outside the house should be positioned so that, when measured from the edges of the flue,
the following minimum clearances exist, which are in accordance with AS/NZS 5601:
75mm
• Out from the wall against which it is mounted.
• From a drain or soil pipe.
300mm
• From a flue terminal, cowl or combustion air intake.
• Below eaves, balconies or other projections.
• From the ground, above a balcony or other surface.
• To a return wall or external corner.
• Measured horizontally, from an opening window, door, non-mechanical air inlet or any other opening into the
building (except sub floor ventilation) or 1500mm in direction of discharge.
500mm
• From an electricity meter or fuse box (prohibited area extends to ground level).
1000mm
• Measured vertically, from an opening window, door, non-mechanical air inlet or any other opening into the
building (except sub floor ventilation).
• From a gas meter.
• From a mechanical air inlet, including a spa blower, measured both vertically and horizontally.
• A flue terminal of this type shall not be located under a roofed area, unless the roofed area is fully open on at
least two sides, and a free flow of air at the appliance is achieved.
