Hello all wise and knowledgeable ones (and all others too ;o)
Yet another question regarding Worcester-Bosch Greenstar Boilers. I've been reading through the installers guides for my new boiler (HE 40+) and creating a check list of tasks to be done whilst installing it. One of parts in the commissioning section is "Check automatic air vent is open" As far as I can tell, opening the automatic air vent is achieved by removal the little plastic screw from its home, is this correct? Also, if the plastic screw is to be removed during commissioning, does it need to be replaced at a future point, and if not, should it be kept in a safe place anyway?
Thanks once again for any and all answers.
