boiler flue heat deflector
 

Anyone know how close to a plastic bath waste you can position a boiler
flue? IIRC 75mm is the rule, but would a deflector enable you to get closer?
Or maybe the bath waste itself could be replaced by the type of heat
resistant plastic used in condensing boilers?
In this instance every little helps since CORGI man decided to use the old
flue hole, leaving the base of the new boiler just 2" above the kitchen
worktop. Told the customer it was "the law". By my reckoning it could go up
at least 15".
Any thoughts appreciated.

1) See if you can download the manual for that particular model this is
the difinitive answer.

2) It will depend on the flue type and the rating of the boiler.
but typically this is 75mm for a typcial fan assisted flue/duct.
(I ues that must be clear minimum and not
between centres as that would be very close).

3) The issue might not be so much about heat from the flue but
restricting the path for the air intake.

OK. Thanks. I'll talk to Baxi, but even 75mm allows me to raise the boiler
15".

I can picture it now. The old boiler had a big balanced flue hole and the
installer reused the hole for the flue/duct.

Usually when I come across this situation the old hole is just where you
want to put the fixing for the new boiler...

But, as most new boilers have a top flue, the base of the boiler ends up
lower down than before which, in this case, renders the kitchen worktop
unuseable. I can't believe anyone with an ounce of respect for their
customer would do that, but my experience of plumbers suggests that they
inhabit their own little twilight world where ripping off the customer is
sport.
There are people that, if you give them a tenner, will give it back to you,
and then come and steal it.

"Some" new boilers have a back entry option for the flue (Glow Worm for one)
thus your displacement problem ceases to be pertinent

Sounds like some (ex)customers I know.

Most boilers have an option to put the flue at the rear of the cabinet
rather than the top. However some models require you to order a different
flue/duct when you buy.
