5. Wait approx. 5 minutes for the tem-
perature to level out and then
observe the display on the pres-
sure gauge:
The tested area is sound if, within a
further 5 minutes, the displayed
pressure does not drop by more
than 1 mbar.
Danger
Escaping gas leads to a risk
of explosions.
Check the soundness of the
test connector.
6. Vent the gas supply pipe.
Note
Prior to commissioning, vent the
gas pipe and gas float; for this
route the venting line outside.
Check with a test burner, whether
the gas/air mixture is combustible.
7. Leave the soundness test set fitted
to the equipment.
Function test without gas supply
Check the function sequence (see
program sequence on page 25).
Switch ON the main isolator (out-
side the installation room).
Start the burner; for this, switch ON
the system ON/OFF switch at the
control unit.
With the soundness test set still
connected, gently build a pressure
of approx. 20 mbar (gas shut off
valve closed).
