To facilitate servicing, the air heater must be
fitted with an approved gas service tap and
union fitting or union tap adjacent to the
appliance.
The inlet gas supply line must be installed so
as to permit the access door to be opened
and to allow removal of slide out burner
assembly.
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 7.
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
