Kaden Installer's Manual
Ducted Gas Heaters
If fitting the heater to elevated heights such as a roof, use suitable lifting equipment.
NOTE

GAS INLET CONNECTION
•
All piping must be in accordance with AS/NZS 5601 and any local gas regulations.
•
The connection point for all Kaden model heaters is a female G3/4 compression fitting to AS 3688. For KEX
models this is located at the base of the heaters outer cabinet, and for KUN models the gas feed tube is supplied
loose in the control compartment and MUST BE fitted to suit the installation.
•
A gas cock shall be fitted in the gas line adjacent to the heater and in a convenient location so it can be turned
OFF quickly and easily.
•
The gas supply shall in no way interfere with any servicing of the heater.
The gas supply must be installed by a licensed gas fitter. The gas pipe and gas meter should be
sized so the heater can maintain its required incoming gas pressure at maximum consumption
with all other gas appliances operating at their maximum capacity at the same time as the heater.
NOTE
1.5
ELECTRICAL POWER SUPPLY
The heater is pre-wired with a 3-pin plug and lead, and shall be plugged into a standard 10 Amp 220 to 240 volt
fixed switched socket outlet adjacent to the heater, in a convenient location so it can be turned OFF quickly and
easily.
A qualified electrician must install the 220 to 240 volt wiring according to local regulations.
NOTE
Switch OFF the power and unplug the heater before touching any wiring. If any electrical wiring is
damaged, it must be replaced by the manufacturer, its service agents or an electrically qualified
IMPORTANT
technician, in order to avoid a hazard.
The electricity supply must be 220 to 240 V at 50 Hz, and from an authorised power supplier. Generators should
never be used, as their output may be incompatible with, or prone to damage the heater's electronic components.
