my radiators rattle any Suggestion of how to fix the problem

GARRY, February 2012
This is a incorrect water pressure eroor code, too high

harv, April 2008
F40 = Incorrect System Water Pressure

Possibly too high? Above 3 bar?

If so, make sure your filling loop is isolated, and bleed of excess
water through a bleed valve on a radiator until at correct pressure.

If you want the manual, email me tony@oilburnerservices.com
