8. Final
inspection
To ensure the appliance is working correctly and safely, check the following before use:
8.1 Gastightness
N.B.
All connections must be gastight.
!N.B.
The maximum pressure to which the gas control block may be exposed is 50 mbar.
➠
Test the connections for gastightness.
8.2 Gas pressure/pre-pressure
The burner pressure is factory adjusted; see type plate. It is not necessary to test the burner pressure.
The pre-pressure in domestic installations should be tested however, as this can vary.
➠
Check the pre-pressure; see
Photo 18
for the measuring nipple on the gas control block;
8
➠
Contact the power company if the pre-pressure is not right.
8.3 Igniting the pilot and main burner
8.3.1 Pilot
➠
Test that the pilot ignites properly, see the User manual, section 4.2 Remote control:
- the pilot burner should ignite at the fi rst attempt.
If the pilot does not light, then
➠
Check whether or not the ignition sparks:
a) If not, the ignition wire is probably touching something metal;
b) If it does, there is probably air in the pipes.
➠
Bleed off any air in the pipes and/or;
➠
Move the ignition wire so that it does not touch anything metal.
8.3.2 Main burner
N.B.
The burner should ignite evenly and should not pop as a result of delayed ignition.
➠
Test the working of the main burner from stand-by (pilot) mode (see the User manual, section 4.2 Remote control);
➠
Once the gas valve has opened the main burner should ignite within a few seconds.
!Tip
When
the
gas valve opens the motor will start to run; this is audible.
