3.7 Gas Connection
EURO-C 4000 RJL air heaters are designed to
operate on either natural gas (G20) or propane
(G31) / butane (G30) gas. Refer to the
specifications in section 2 of this document and to
the data plate for details of supply pressures.
The gas meter and gas service must be checked by
the supply undertaking to ensure that they are
adequate to deal with the total load of all gas fired
apparatus installed.
Connection to a gas service may only be carried out
by appropriately qualified persons. The gas
installation must comply with the rules in force
using materials appropriate for gas installations.
Check that the gas category is in accordance with
the data described on the air heater.
An adequate gas supply sized to provide the
dynamic pressure for the volume required for the air
heater(s) is essential to maintain the nominal heat
input. Account of other gas fired plant using the
same gas service must also be taken into account.
A 90° action, positive stopped gas service tap
must be fitted adjacent to the appliance, fitted in a
manner to facilitate appliance burner removal for
service purposes, see figure 6.
Ensure that the gas service includes a filter and has
been tested and purged in accordance with
prescribed practice prior to commissioning and
taking the appliance into service.
As a rule, gas service pipes should not be routed
through air ducts. Should it be necessary to do so
then pipe work joints must not be made within the
air duct.
