With room sealed boilers, vents serve only to dissipate heat as not required for combustion. The mi's for the boiler shown dont require them wich makes sense as most modern room sealed boilers are in essence appliances within there own compartment (casing) which is ventilated by the fan drawing fresh air through the concentric flue in to the inner boiler casing.

Believe it says "maybe required".
Depends who you speak to, on the AI course I was told it doesn't but on the phones they say they do

Without trying to hijack this thread king, heres one I did today with cross overs at the bottom. The gas came out the floor in a silly spot but it was an LPG park home so wasnt going to mess around with it underneath.
Sorry about the Worcester, was a sub contract job.
It looked a bit better in the flesh I thought, looks a bit busy in the photo but you get the idea, sort the pipes out ASAP then continue up the wall straight.

Notice all toss bonded excluding the gas? I hate a tidy job. Much better to have pipes all over under boiler IMHO, make u feel less self aware!
Over engineering 🙂 as with the 40mm condensate run!!!
next time it will be better. Starting to build some confidence up now 🙂
looks good nostrum !!!
But wheres the sink hole for the lpg?
Yeah, I think its because the meters are off a communal bulk tank externally and pme earthing arrangement so different potentials possible per park home.
leo, believe it or not I didn't mess up one bend! A few needed making a touch bigger but that was easy enough. Normally I mess one up but as it was my tube I took my time!
I don't do it for the customer mate, use to fit exactly the same for warmfront and will do for eco etc, if I'm happy with the job then 99 times out of 100 so is the customer anyway. I do it so that I can walk away knowing I've no come backs, and your work is your business card.
Thats fair enough, I do a neat job but don't go over the top. I'm not sure it's apreciated.
RPH requires a sink hole of no less than 25mm 🙂
unless low lever ventilation is at floor lever
rph's made after 2005 require a minimum of 25mm
made before that you have to provide it aswell but they don't give you a minimum size however i had a chat with an inspector over it and he said if you install a new applience make the sink hole 25mm to cover yourself 🙂
oh refrigerators needed a purpose provided 13mm minimum size.
In my NICEIC lpg safety on site guide.
