The customer is always right.
Just keep charging him for your call outs.

When he calls the boiler manufacturer, you're the one they are going to blame.

+1 sorry but you shouldnt of installed it or leave the big mag filters on for a month or two with alot of cleaner in the system and do a mains flush in the end

If landlord or customer does not want system flushing I write it on benchmark for the boiler manufacturer to see if they are called out just shows you did what you could

anything customer declines i write on the comissioning benchmark then get the customer to under-sign it off!.

did you fill in the benchmark?
