fully qualified plumber in two weeks.

Sorry Fuzzy, was watching a bit telly there.

The boiler is rated at 60000btu so you convert it to kw by dividing by 3414 = 17.58kw
As it is an old boiler, unless it states the output is net on the data plate, assume it is gross so divide 17.58 by 1.1 = 15.98 rounded up is 16kw.

If the cupboard (compartment) is vented direct from outside you base you vent sizes on the FULL input of the boiler
Vent sizes would be 16 x 5cm = 80cm² at high level and 16 x 10cm = 160cm² at low level

If however the compartment is vented to the kitchen and then to outside you need to calculate the compartment vent based on overall input which would be 16 x 10cm = 160cm² for high level and 16 x 20cm = 320cm² for low level.
You then need to calculate the combustion air requirement from outside so deduct 7kw from the 16kw for adventitious air = 9kw x 5cm = 45cm² needed

Easy innit. Try to remember that one as you will need it.

wrong.lol.

I agree with Fuzzy. 10 weeks or 50 days training in this industry is a joke. A real apprenticeship is for 4 years and only in year 2 (or when your considered capable enough) can you actually do work.
There are too many of these fast track plumbers that have little practical on the job experience and they are taking away work from the rest of us who slogged our guts out for years to reach the standard we have now. No sympathy on the lack of your progress on the job front either. There's too many of you now and not enough work to go round so that's why you can't get a job. I for one will only take on a school leaver and give him a proper apprenticeship so that he has the correct training on and off the job.
Fast track? Says it all really.

Don't Know if you read it properly, but Its About 120-130 days in total on the fast track, Where as the college is 144 or so days.

Are you saying that people are only worthy to be a plmber if they start from the bottom up, passing tools, watching how someone else does it, making tea and working your way up?

I have taken on and trained 4 apprentices over the years and when the on i have with me now has served his time i will start another one.
I do it because i want to pass the skills on the way it was passed to me and give some youngster the chance i had. He will also be taught the way i want him to learn. It is like a blank canvas.
I don't do it for the cheap labour as they have all been on tradesmans wages before their time was out and it is not for what i get in training grants (through Snipef) because that is laughable. It used to work out at £1 a day with a final bonus given at the end of about £1800 (it was something like that with the last one) when they were qualified.
Split that over 4 years and it is not a lot of financial incentive. It doesn't even pay for his bacon rolls. They are also enrolled in the plumbing pension scheme (which also costs me).
They have all been 16 and one 17. Sure young lads are daft and loose interest sometimes but you just need to know how to handle them. We have all did daft things when we were young. Youngsters generally have little financial responsibility (bottle of wine at the weekend!) so accept lower wages. Treat them right and they will be loyal to you but when the time is right they will move on and do you proud.
I can't see me ever taking an adult trainee. They had their chance and blew it years ago. They now have families and mortgages to pay and loyalty is not part of their road to riches beliefs. As for working for free. Are you having a laugh? Not a cats hope in hell.
There are apprenticeships out there, always has been just not in the numbers you think there should be. The numbers taken on depend on the workload. At the minute things are not great but there are still some who will be taken on in the summer.
