-
Start the dryer following the user instruction
-
Check the inlet pressure, with the burner
working.
-
Switch off the dryer.
-
Close the interceptor device.
-
Take off the monometer.
-
Close the screw of the gas valve pressure
tube and control the tightness.
-
Open the interceptor device and control test
the tightness.
The dryer must not working if the gas pressure is out of
the limit shown in the reference table.
14. GAS CONNECTION: FINAL TEST
Once the connection works are taken over, the
equipment and the installation must be controlled.
It is necessary to control:
- that the connection are made respecting the
instructions written in this manual;
- that the safety rules and the laws about this
subject are respected;
-
that gas connection are tightness tested.
Switch on the machine following the user manual
instructions controlling the burner lighting on and
the flame aspect.
Do a gas test with the volumetric method. Using
the gas contactor, control how much gas was
used in a fixed time unit: this value must be
compared with the values in the tables.
15. HUMID AIR AND BURN GAS EXAUST
The humid air and burn gas exhaust system must
be realized following the rules in force.
To avoid lack of humid air and noise, the exhaust
joints to the outside must be made tight with high
temperature resistant material (filler, putty,
silicone preparation.
Gas heated tumble dryer are B22 equipment, it
means they are gas equipment which depend on
a aired room without any wind protection device
with blower behind the burning room.
Dryer burned gas must be brought outside
through a chimney.
Burn gas and humid air pipe must be the shortest
possible one and it must be rising to the exhaust
chimney.
In the lowest point a condenser drain must be
provided, this drain derivation must observe the
local rules in subject of water drain connection.
The dryer is equipped with a suction fan which
produces its typical noise while working.
To reduce the noise level, a muffler can be
installed on the drain (it can be found in
specialised shop).
16. STEAM CONNECTION
Only for steam heated tumble dryers, a
connection to the steam system must be provided.
This connection must be performed by qualified
personnel in compliance with the national and
local rules in force.
Steam must satisfy the minimum requirement
which are written in the technical data sheet; all
system parts must be certified.
The steam system must be realised following the
below diagram:
System elements are identified as below::
1) On - off valve;
2) Filter;
3) pressure reducing valve (if necessary)
4) Safety
valve
IN) Machine steam exchanger inlet
