the burner should stop within 2 minutes and the signal lamp indicating chimney
should light (if not, flue thermostat should be replaced)

turn off the main switch, turn off gas supply at the gas service cock
-
refit the flue duct
-
remove the temporary flue obstruction
-
wait until the thermostat phial has cooled (approx. 10 minutes after intervention)
