heat will then be moved through the transfer system to other parts of the house. In a typical installation, it
will take approximately one hour to warm rooms with transferred heat.
1. When mounting the inlet vent make sure it’s far enough from the flue to avoid excess heat on the fascia
and will not ingest too much smoke when the firebox is opened, (Between one and two meters from the
flue.) The fascia mounting body must fit freely in the hole
2. Finally, attach the ducting to the rear of the fascia body, secure with provided cable tie, repeat step for
outlet vents.
**SEE PLACEMENT OF OUTLETS
3. Slide the outlet vent fascia mounting back into place and screw into place using the four 6x¾ pan head
screws provided. Press the fascia ring onto the body and then screw the centre diffuser into position
4. In the ceiling cavity suspend the motor junction from the rafters. There is a directional arrow on the main
fan body showing the flow of air through the inline fan unit. When fitting the ducting, ensure that the
arrows on the motor housing are pointing in the direction of the outlet vent.
DIGITAL CONTROLLER
The enclosed Weiss Heat Transfer System comes complete with a wall-mounted controller. Weiss Heat
Transfer Systems MUST ALWAYS be wired through the included controller. The best placement is in a
convenient location within the room with the heat source, around light switch height, this can vary
depending on room layout –but use this as a guide. The controller needs to be fitted in accordance with
the instructions enclosed with the controller unit. Ensure the controller is located in the same room as the
heat source, approximately 3-4 metres away at wall switch height.
FINAL STEPS
Finally, connect the wiring as illustrated in the included wiring diagram.
Note: Approximate means of disconnection are required to be incorporated in the fixed wiring. This product
must be installed by registered Electrician.
Important mounting information
1. Use no more than 3 metres of ducting from the inlet to the fan motor and 3 metres to the junction.
(This will allow enough supplied cable to connect the controller to the fan)
2. Suspend the motor and keep it at least 150mm above the ceiling or insulation.
3. Keep the ducting as short as possible from the junction to the outlet vents
4. Ensure the ducting to each outlet is the same length to ensure equal airflow to each room.
5. Ensure all ducting is at least 1.5 meters away from the flue in the ceiling cavity
CLEANING AND MAINTENANCE
Isolate the unit from the mains before cleaning. To clean the fascia, simply wash it by hand with a damp
cloth and warm soapy water. Do not use abrasives or solvent cleaners.
The fan unit needs to be wiped clean internally every 2 years to remove dust and residue from the fan
blades and motors and the terminal connections also need to be checked and tightened at this time.
All this maintenance work must be undertaken by a registered Electrician.
LENGTH OF DUCT
Have the Heat Transfer System fan and junction-to-room lengths as short as possible, 1x length (3mtrs) of
ducting must be fitted between the inlet grill and the fan motor. Have the duct stretched out and as
straight as possible. Be sure to cut off any excess. Support duct and bends from the rafters as necessary.
**PLACEMENT OF OUTLETS
Keep the outlet ducting lengths as short as possible - this increases efficiency. It is not necessary, to put
outlet in the centre of the room. The outlet vent needs only to be in the corner of the room.
Note: Initially, the fire or heat source needs to be running at maximum. It takes a while to heat a room and is
dependent on humidity and on the moisture content of the furnishings. We recommend that the door to
the room with the heat source is left ajar to ensure that air can circulate through the room. We also
recommend that the house is aired out occasionally in fine weather. High studs, or badly insulated homes
will remain more difficult to heat than low ceiling –well insulated homes.
