INSTALLATION INSTRUCTIONS
INSTALLATION INTO AN EXISTING FIREPLACE
The Hot Box system is designed to be installed behind a cast iron insert or fascia.
1. Check that the fireplace and chimney are in working order, sound condition and clean and
free from obstructions. Any cracks or gaps found in the masonary of the fireplace, must be
sealed prior to the installation of the Hot Box.
2. Measure the fireplace opening to ensure that the Hot Box will fit into the opening.
3. If fitting the Hot Box into an existing fireplace, using the existing cast iron insert, you will need
to remove the back from the cast iron insert. This will require the mantelpiece and insert to be
removed from the fireplace prior to installing the Hot Box.
4. Install Hot Box by placing it centrally in the fireplace opening and fit cast iron fascia up to the
Hot Box, ensuring that the fascia is firmly touching against the brickwork of the fireplace and
the Hot Box. Remove fascia and permanently fix the Hot Box to hearth using the location lugs.
5. Before sealing the cast iron fascia to the brickwork have your gas fitter supply a 15mm copper
pipe into the fireplace and Hot Box through the hole provided for connection to the Magiglo
burner.
6. Once the gas supply has been installed into the Hot Box fit and seal the cast iron fascia to the
brick work and install your desired mantel piece to complete your fireplace.
7. Have your gas fitter refer to the Magiglo Series Installation Instructions for connection and set
up of the Magiglo 360 Series Gas Coal Set.
8. A 225mm approved gas cowl is required to be fitted to the top of chimney to stop down draft
and rain entering into chimney.
9. Ventilation of 40,000 sq mm must be provided to outside air for the room that the Hot Box is
installed. Four standard vents is normally enough. Check that they are clear of blockages.
IMPORTANT
After installing gas coal/log set the following commissioning procedure must take place
before leaving premises.
COMMISSIONING PROCEDURE
Once the fire is installed and operational, the installer must check for spillage. Carry out the lighting
procedure and turn the fire to high. Allow to warm up for 10 minutes and then using a smoke match,
set 25mm down and 25mm inside of the fire opening, run the match across the width of the opening
to check that all of the smoke is drawn away.
Repeat the test with doors and windows to the premises open and closed, and with any extractor
fans in the same room or adjacent rooms running on high. The fire should continue to clear its
combustion products. Also operate any other flued appliances in the same or neighbouring rooms
and ensure they continue to function satisfactorily as multiple flues can work against one another.
If spillage is detected during this procedure it could indicate a faulty flue or lack or ventilation. If the
problem cannot be rectified immediately, disconnect the appliance, and advise the customer not to
use the appliance until the problem has been resolved.
The customer should always be advised of the need for regular servicing and checks to ensure the
continued clearance of combustion waste products.
NOTE: A slight smell may be apparent for first few hours of use. This is due to the heat resistant
paint curing. It is recommended to open windows in room for the first lighting.

OPTIONAL POWER FLUE
Introduction - the Power Flue System
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’.
POWER FLUE APPLICATION
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.
THE INSTALLATION MANUAL OF THE REAL FLAME POWER FLUE SYSTEM IS TO BE READ IN
CONJUNCTION WITH THE INSTALLATION MANUAL OF THE REAL FLAME PRODUCT BEING
USED. THE DESIGN OF THE REAL FLAME POWER FLUE SYSTEM IS SUBJECT TO COPYRIGHT
AND ALL INFRINGEMENTS WILL BE VIGOROUSLY PURSUED.
VENTILATION REQUIREMENTS
Air supply to the unit is to be in accordance with ventilation Clause 5.4 of the Gas Code 601.
Ventilation requirements do not change by using a power flue.
All Real Flame installation manuals have the ventilation areas clearly defined for each product.
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.
‘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.

or any other opening into a building with the exception sub floor ventilation..........500mm
ELECTRICAL
SHOULD THE SUPPLY FLEX AT THE BACK OF THE FIREBOX BE DAMAGED, A SPECIALLY
PREPARED FLEX IS REQUIRED. FOR REPLACEMENT CONTACT THE MANUFACTURER.
THE ON/OFF WALL SWITCH MUST NEVER BE ATTACHED TO A METAL FRAME.
WARNING
Whenever servicing the power flue system, always turn off the electrical power supply and
close the manual gas control valve.
IMPORTANT INFORMATION
In addition to the instructions in this manual all national, state and local regulations must
be adhered to. These include but are not limited to:
• Australian Standards AS3000 - Electrical Installation.
• Australian Standards AS5601 - Gas Installation.
• Local Gas and Electrical Authority Regulations.
• Municipal Building Codes.
The power flue should be serviced every 12 months by an authorised technician. If repairs
are needed an authorised technician must carry them out.
FITTING THE MOTOR
The power flue motor has a 150mm spigot and a twin skin spigot of 150mm & 200mm. The single
spigot fits over the vertical flue and the 150mm/200mm flue attaches to the horizontal spigot.
FLUE SIZE
All flue prior to the motor is 150mm/200mm twin skin and all flue after the motor is 150mm/200mm
twin skin.

OPTIONAL POWER FLUE (continued)
Installation Instructions (continued)
HORIZONTAL FLUE RUN
The maximum length of horizontal flue run is to be 13.5 metres with a maximum of four (4)
bends; these bends can be 45° or 90°. The horizontal flue run is to have a grade downwards
from the motor to the termination.
VERTICAL FLUE RUN
The minimum vertical flue run is 900mm from the top of the firebox (1500mm from the floor). If a
longer vertical run is required twin skin flue 150mm & 200mm can be added between the muffler
top and the fan. The flue can be cut to the required height.
FLUE CLEARANCES
All flue clearances are as per the requirements listed in the heater specifications.
TERMINATION
The termination to be used for all horizontal installations is to be 150mm cowl that has been
approved as a horizontal cowl.
Installation of Power Flue Kit
POWER FLUE MUFFLER
The power flue muffler has a spigot at each end. The end that attaches to the firebox has a
spigot equivalent to the inner flue spigot diameter of the firebox, the top of the muffler has a
150mm spigot which the motor fits to, or the 150/200 twin skin flue if required. The flow arrow
on the muffler is to be pointing up.
WIRING (see wiring diagram page 22)
A 3 metre lead is supplied with the power flue, this lead has a different connection on each end,
one end is plugged into the connection on the left hand side of the firebox and the other end is
to be plugged into the fan. The wire coming from the rear of the firebox with the standard 3-pin
plug attached is to be plugged into a power point. A single gang wall switch is also supplied
attached to the 3 metres of lead; this wall switch is to be attached at a location accessible to the
client. No other wiring is required.
SERVICING OF THE POWER FLUE MOTOR
The Real Flame Power Flue motor is designed so as to make servicing the motor a simple task.
The power lead connected to the motor is to be disconnected (unplugged) and the two side clips
are to be undone, the fan motor will then lift out for servicing. The fan Motor box connected to
the flue does not have to be disconnected from the flue.
