Kaden Installer's Manual
Ducted Gas Heaters
The Kaden Networker controller is used as a Wired Wall Thermostat and is also the interface to
set Installer Parameters and obtain diagnostic information on the Kaden KUN4 and KUN5 Ducted
Gas Heaters. A spare Networker should be kept on hand for such purposes.
NOTE
9.2.2 Adjust Networker Parameters
Adjust heater parameters via a networker, as follows:
a. Connect networker, power up unit
b. Press Key 5. 'Clock setting mode' displays. Confirm that the clock display is flashing.
c. Press and hold Key 2 and Key 4 until 'Installer parameter access' displays.
d. After the message clears, press the mode key (M) to toggle between networker parameters (n01), and heater
parameters (H01). If more than one networker or heater unit is configured in the system, repeatedly press the
mode key until the desired heater unit is selected, e.g. H01 ID01: 1.
e. Press Key 1 or Key 2 to scroll through, and select, the required parameter ID, e.g. H01 ID01: 1 (refer to Table
7 on page 33). (Key 1 = next ID, Key 2 = previous ID.)
f. Turn the rotary dial to adjust the parameter value, e.g. H01 ID01: 1.
g. Press the on/off button to save and exit.
All settings are saved automatically when the on/off button is pressed to exit networker set-up
mode.

KUN4 & KUN5 COMMISSIONING INSTRUCTIONS
With a correctly designed and installed ducted system, generally, the balancing damper in an outlet should be
initially set as follows:
•
Living areas 100% open
•
Bedrooms 50% open
•
Bathrooms, ensuite & Laundry: 25% open
9.3.1 Initial Ignition and Gas Inlet Pressure Check
•
Disconnect the power supply from the system at the power point.
•
Connect a networker to enable access to the heater installation parameters.
•
Locate the inlet gas pressure test point and loosen the captive screw three full turns anti-clockwise. DO NOT
remove the screw.
•
Attach a manometer to the inlet gas pressure test point on the gas valve (refer to the label on the gas valve for
the test point location).
•
Purge air from the gas piping and turn on the gas at the supply tap.
•
Connect and switch on the 240V power supply at the power point.
•
Turn on the thermostat and set the temperature to maximum (see the Owner's Manual for operating instructions).
Ensure that all zones (if any) are open. It should be possible to see the burners operating at the heater.
If there is air in the gas line, the heater may not ignite on the first attempt. Ignition attempts will
occur automatically. Allow time for the heater to rectify itself as it may simply be purging air. If
ignition is not successful, the heater will cease ignition attempts and lock out with an error code.
NOTE
If this occurs, take note of the code and reset the heater (refer to the Operation manual).
