| WARNING! Mains voltage is expected during test, follow TOPs P4 live testing procedure |
Measurement:
Allow the fan to run and the ignition sequence to begin.
Once sparking is seen at the electrode there should be
approximately 1.5mb gas pressure shown on the U-gauge.
Does the gas pressure react as above?
Note:
When pressure gauge is removed the pressure test point should be tightened and checked for gas tightness.
