Figure 6 - Vertical suspension kit

The air heater is equipped with threaded sockets to 
suspend the unit (see §12).

• Use the suspension kit that is compatible with your

air heater. The suspension kit is not delivered with
the air heater. Contact your supplier.

4.3  Gas type & connection

The unit is suited for the use of natural gas or propane gas.

The specific gas type that a heater is set up for can be 
found on the packaging labels and on the heater badge. 
The heater can be converted to another gas type. Contact 
your supplier for more information.

The working and standing supply pressure must be 
a minimum of 17 mbar, and a maximum of 50 mbar, 
measured at the inlet pressure nipple of the gas control in 
the heater.

 NOTICE 

 The supply line’s manual isolation valve must be 

placed within reach of the heater.

 NOTICE 

 All gas supply lines must be mounted without any 

mechanical tension.

 NOTICE 

 Always clean the inside of a gas supply line 

before connecting it to the air heater. Place a gas filter in 
the supply line when needed.

 CAUTION! 

 When using pressures above 60 mbar to test 

the supply lines, always close the manual isolation valve of 
the air heater.

For United Kingdom only:

The supply line for gas must comply with the Gas 
Engineers publications UP-1 and UP-2, as well as with BS 
6891.
