INTRODUCTION - THE POWER FLUE SYSTEM
INSTALLATION INSTRUCTIONS
POWER FLUE DESIGN
A ‘flue’ using a fan to remove or assist in removing combustion products from an appliance, is
known as a ‘power flue’.
A power flue application can be used to enable a client to have a decorative fire with a horizontal
flue run or a vertical flue run where flue space is inadequate for the normal flue.
WHERE FITTED A POWERFLUE SYSTEM MUST BE DESIGNED AND INSTALLED TO MEET
GAS INSTALLATION CODES AS5601.1.2013 CLAUSE H2 - POWER FLUE DESIGN.
Where the powerflue option described in this manual is installed, it represents a Power Flue
installed in accordance with AS/NZS 5601.1 Paragraph H2. The powerflue system when installed
to the instructions is designed to comply with the requirements of AS/NZS5601.
The powerflue must be installed and commissioned by the installer in accordance with Paragraph
H2.2.7 AS/NZS 5601.1.
VENTILATION REQUIREMENTS
A requirement of the gas installation code AS/NZS5601.1-2013 is that ventilation is required as per
the manufacturers instructions. Clause 6.10.9.5 of AS/NZS5601.1-2013 sets out the ventilation
requirements.
ACCESS TO POWER FLUE MOTOR
Access must be provided to the flue motor, this access MUST be at least 400mm x 400mm.
There MUST be a minimum clearance of 250mm between the top of the motor and any fixed
object i.e. ceiling or stud work. This is so the top of the fan box can be removed.
WIRING OF THE POWER FLUE
All wiring for the power flue is carried out at the factory and plug connectors are fitted for easy
installation. The power supply for the power flue is via a 3-pin plug at the rear of the firebox that
can be plugged into a power socket within the cavity.
ISOLATION SWITCH
If the power point is within a cavity an isolation switch accessible from outside the cavity must be
provided.
WIRING CLEARANCES
Wiring must at all times have a clearance of at least 150mm from the flue.
FAN FAILURE SENSING DEVICE
All Real Flame Power Flue systems are fitted with a sensing device within the unit to ensure that,
in the event of flow failure, the safety shut off valve within the module will go into lockout and shut
off the gas supply to the unit. The device should ALWAYS be in the vertical position. Refer to the
pressure differential switch on page 11.
‘LOCKOUT’
‘Lockout’ is the term used when the module in the unit senses a fault. When a fault is detected by
the module it will shut off the gas and go into lockout. If this occurs contact the manufacturer.
