4.1 Gas burner
Danger!
Danger of burning.
The ignitor electrode (E1/1) begins to glow.
Gas ignites at the ignitor electrode (E1/1).
Note
There is a measuring port for jet pressure at the gas valve, no measuring port for
the gas tapping pressure.
A Test the gas resting pressure, target value: 17.4 mbar
Note
Gas resting pressure: Pressure of gas that is stationary, without tapping the gas.
A Check the gas tapping pressure, target value: 8.2 mbar.
Note
Gas tapping pressure: Gas flow pressure at the connection of the dryer, with the
burner running.
This pressure can only be measured with functional burner, while operating.
A Check the temperature limiter (1F1, 2F1) for continuity.
Warning!
If the front temperature limiter (2F1) has tripped it has to be assumed that the
burner and the connecting cables have sustained thermal damage by a
flashback.
In this case, replace the burner, complete with connecting cables.
At the same time, check the general area of the burner for heat damage.
Warning!
If the rear temperature limiter (1F1) has tripped, check the exhaust air duct and
the fan for heat damage.
