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.
Figure 7 - The air heater's connection clamps
• Connect the wires of the mains cable to the clamps
in the connection box (figure 7).
• Completely isolate the air heater for maintenance
purposes. Use an isolation switch (min. 3 mm
contact opening gap), a power plug or a non-
switched fuse spur. See the electrical wiring
diagram in §11.
