2 screws out and lift cover vertically, give it a wiggle. seal will be sat there.
did my first rapid today, only real complaint is they are bleedin heavy compared to HREs. I will use the jig in future and not the mounting bracket, so that the boiler sits off the wall a bit and it will make fitting the flue a bit easier as my flue hole was a bit small.
As ever with intergas, hold the valves solid when tightening them up on the boiler pipes or you can undo the connectors in the boiler.. hassle but can be avoided.
the pcb doesnt have such an easy access as the HREs, but that will be down to cost saving. I quite like that the condensate drain and prv all go into the drain outlet, bit less work
as for performance, the hex is bigger than the HREs for same kw output, so I gather that the pcb has been adjusted so the rapids dont outperform the HREs, which means we can have a play and get a better performance on hw flow rates if you care to have a read and fiddle when setting them up
As far as winging goes on damaged flues due to packaging, all manufacturers use a similar box, I would be moaning at the merchant or shipper myself!! Oh if you care to have a look at the instructions Anz youll find the template in the same envelope
re warranty, if its on a new boiler I just get the bit and send the faulty bit back via my merchant or call intergas and get the local subbie out or they send their fulltime lad, never had any real issues with backup, at least you know the bloke at the other end is a technician who works on the boiler your chatting about and there isnt that much to go wrong in the first place really.
