Introduction
Thank you for choosing an Intelligas product. Please follow these instructions to ensure a safe, functional and
long-lasting installation.
This information is important and should be read and understood before attempting installation.
If you are unsure of the terminations and their design voltages or function then refer to this guide or our technical
support line, you can call 02381 290444 or you can text 07952269791 and we’ll get back to you as soon as we’re
available.
Siting the panel
Choose a suitable mounting position for the control unit. Mount the unit away from sources of extreme heat. Ensure the panel is
placed in a position where mechanical damage is unlikely and where it can be easily accessed for use and maintenance.
Fix the panel using the marked enclosure holes only. Take care not to damage the internal wiring or PCB of the unit when drilling.
Under no circumstances should wiring be routed behind the PCB of the control panel.
Control panel supply
All our control panels (except the KVM-SF) should be supplied via a fused spur connection unit. The fuse should be changed to one
that’s rated at 5amps.
KVM-SF ONLY if the panel is supplying the fans directly from the PCB then it should be supplied via a 16amp single phase isolator.
If the panel is controlling Inverters and only the output signals are being used then, as above, the panel should be supplied by a 5amp
fused spur.

Field wiring
All wiring from the supply and to the gas valve carries mains voltage (230v ac nominal). The current edition of the IEE Wiring
Regulations should be strictly adhered to, wiring and connections should be made by a suitably qualified electrician or competent
person.
The field wiring voltage to the interlock inputs is reduced to 24 volts, do not connect mains to the air pressure switch terminals,
e-stop, analogue input/output 0-10v control, gas detector or fire alarm terminals.
Please follow the first fix wiring schedule set out below:
1) Main supply 2 core + E 1.5mm (as per regulatory requirements)
2) Gas valve 2 core + E 1.5mm (as per regulatory requirements)
3) Pressure switches 2 core + E 1.5mm (YY type cable)
4) Fire alarm interlock (if req) 2 core + E 1.5mm (FP type cable)
5) Emergency stops 2 core + E 1.5mm (YY type cable)
6) Gas detection equipment, If fitted, 3 core screened (CY type cable)
7) Gas pressure switch, if fitted, 2 core + E 1.0mm (YY type cable)
8) 0-10v signal wiring, if fitted, 2 core 1.0mm (CY type cable)
Where multiple supplies enter a control panel, perhaps in a current sensing interlock. It is preferable that each supply is on the
same phase. If this can’t be achieved, then additional warning labels should fixed in a suitable location on the control panel.
The advice given on these instruction pages, specifically to cable types and ratings may change depending on cable lengths and
installation conditions. If you are not sure about any of the cable types or ratings then contact our technical support team.

Peripheral items installation
Airflow switches (electrical installation)
For airflow pressure
switches use PCB
terminals marked either
intake or extract fan,
these interlocks have a
time delay in the
software to prevent the
effects of pressure
switch flutter.
For emergency stop switches use PCB
terminals marked Estop
Fire alarm interface (if used)
If fire alarm interface is not to be used then
link as shown.
This termination is low voltage and no isolation
relay between the Intelligas panel and the
building fire alarm is required.

Commissioning
Double check all terminations have been made and checked for tightness, check all peripheral equipment such as emergency stops
and pressure switches are connected and the covers are in place. The power may now be applied
After initial power up start all fans and set any speed controllers to minimum, assuming the minimum fan speed still satisfies
minimum ventilation levels in the kitchen continue and set the pressure differential switches. This can be done by slowly increasing
the Pascal setting on the pressure differential switch until it clicks off, then turn it back down in 5 Pascal increments waiting 30
seconds each time until it makes again. Repeat this procedure for each pressure switch installed.
Once the pressure switches have been set up and all emergency stops are reset press the reset button, the two top LEDS will show
green and the unit will beep 3 times to indicate that all the interlocks are ok. The bottom LED will illuminate amber requesting the
reset button to be re-pressed to enable the gas valve. Once re-pressed the bottom LED will change to green to show the gas valve
output is energised.
There is a delay on the fan pressure switch inputs, this is to overcome high winds momentarily effecting the operation of the switch,
the panel will show any fault immediately as it happens but the gas will not be shut off or warning beeper operated until the 20
second timer has elapsed
The unit is now commissioned and ready for use.
