Return Air Ducting
A return air duct grill must be provided and should draw air from a central location within the
house. The maximum recommended duct length is 6 meters. This ducting may be installed to
either or both side return air connections found on the left and right-hand rear sides of the heating
unit. In instances where the unit is drawing air from a building cavity make certain that it is fully
sealed. This ensures that outside air is not drawn into the system, which will affect performance
of the heater. A filter is recommended to be used only in the return air grill for dust free air
circulation into the heater.
Outlet Registers
Suitable outlet registers/diffusers must be provided in all areas being heated.
Filters
The use of filters is recommended in order to keep the duct system clean and to collect dust, lint
and other debris from entering the heating unit.
A filter is installed only in the return air duct
.
It should be in a position where it is accessible for ease of cleaning. Where a filter is fitted, the
return air grille dimensions should be increased by at least 30%.
Please Note
:
Filters are not allowed to be put on the supply air vents under
any conditions.
Add-On Cooling
Where, either presently or in future, with any Super Star model a suitable add-on cooling can be
installed with the proper indoor refrigerated coil section, it should be installed at least 1.5 meter
downstream of the supply air duct connection.
System Balancing
Provision for system balancing by using dampers or other suitable means for adjusting airflows
must be provided in the duct layout.
Fan Adjustment
The fan is preset at the factory to operate at a designed speed. The Fan speed should not be
changed without the expressed authorisation of the manufacturers.
Notes:
1. A 30-second delay is given to run the fan from the ignition taking place.
2. The fan speed is factory-set so that discharge design air temperature does not exceed 60 ºC.
3. No modification inside the heater is allowed by any body at the installation site. If the heater is
found modified on site Eco Pacific will not honour the given warranty conditions and will not be
responsible for the consequences whatsoever if occurs from the modification in gas or air flow
change or parts and components change.
