Gravity fed? Potterton 30e/40e , works with Hive

[finlaand]

Hi there

I bought a Hive heating and hot water kit from screwfix, set it all up and seemed fine but hot water and heating came on not as expected e.g. hot water light started heating.

I read the hive needs to be set to gravity fed if boiler is gravity fed, how would I know? Boiler must be 25 years old.

By some miracle found the original manual, and on page4 schematic shows a Gravity DHW/piump over run theromstat. Call me daft (probably), but that means 100% its a gravity fed boiler?

..if so will switch hive to gravity fed boot up option and see if works
