Concerned about potential flue arrangements.

[Matt0029]

I am on a site and the potential flue arrangements on 2 properties is causing me concern. It has been ok'd by another gas safe engineer who no longer works there. So wondered if I could have some opinions? I have uploaded a picture. The flues are 1800mm apart diagonally. And the flue shown by the flue terminal cover taped to the wall (the other flue is the cross taped on the adjacent property) discharges at 450mm to the adjacent properties boundary, though a flue needs to be 600mm from a boundary when facing it. You are apparently allowed to get over this if you use a plume kit and angle the flue away from the boundary so that it can go up to 600mm as long as you are at least 300mm from the boundary. What are your thoughts acceptable? Hope that makes sense.

Can the flue route be changed on the one with the taped flue collar to exit out the other wall ? Cheers Kop

 

[sammathias]

Probably another new build within a foot of that wall kop. Christ they sure cram them in thesedays.

Plume kit not really the answer me thinks. Always difficult on new builds as they build 4 houses on a postage stamp.

 

[Matt0029]

Thanks still not really acceptable with a plume kit? I'm wasn't too keen on the idea. But was the only way I could figure to so it.

 

[Matt0029]

Thanks, the one with the collar taped on has a property the other side of it, is a semi detached. The only other option with that boiler/flue is to get them to slightly change the kitchen layout ( Joiner hasn't first fixed the property yet). So that the kitchen is slightly bigger and the downstairs toilet slightly smaller. So the boiler can go in the kitchen on this stud wall separating the kitchen and the downstairs W.C. Wall would need altering to give clearance of over 300mm from the window to the boiler flue.

You have got to sign em off fella seems like a headache job stick to manufacturers instructions put it back to the architect or m & e consultant and cover your own back get it in writing to fit in that position if anything goes wrong your coverd . Kop

 

[Matt0029]

Thanks I go back to the architects. Its not correct with the boundary begin 450mm from the flue. Gas safe state a plume is acceptable but not ideal. Do you see the other flue being 1800mm away diagonally as a concern also? I know if there facing each other needs a gap of over 1200mm.

 

[king of pipes]

1800mm is ok I would say bud - flue 450mm from the boundary no cheers Kop

 

[Matt0029]

I understand what you ment now, and take the flue out as a side exit one. I cant as it would be within 300mm from a window. Very poor planning.

 

[Matt0029]

Thanks for the help kop. Have the boiler manufacturers new build rep. Coming out to discuss issues. As business I work for are definitely wanting it fitting there. Uploaded another picture if that shows the lay out clearer. Thanks.

 

[king of pipes]

I personally would not fit them like that stick with what the manufactures say bud you could ring and ask gas safe for their opinion but you could get the answer you won't want to hear . Best of luck kop

 

[Matt0029]

Thanks. If they were to say no I would tell the builders the plans need reconfiguring. Im not happy with the lay-out that's why they have got the boilers rep. To asses the proposed lay-out as well.

 

[king of pipes]

Good for you Matt let us know the outcome bud . Cheers kop

 

[Scott_D]

What are you fitting?

 

[Matt0029]

Fit ideals on this site, Scott.

 

[hammers4spanner]

If you are the gas engineer on site subbed in by the builder then arnt they employing you as the professional gsr on site ?

 

[Matt0029]

Thanks I work for the builder full time. The position had been ok'd by an old colleague before. But he no longer has gas Safe registration. Thanks spanners4hammers, even if the boiler manufacturers say it's ok. It is still down to me to make the judgement as will be me signing it off. I'm pretty new to the job. Passed last year when I completed my nvq level 3.

get it in writing also get something from gas safe in writing

 

[hammers4spanner]

You say the business you work for defo want it fitted their ?
If so then make sure you tell them exactly why you think not and do NOT feel pressured into anything you're not happy with.
The good thing is you're trying to find away round it however from experience the builder will just expect it to go their.

Ultimately if you get anything in writing(doubt you will )your the one still signing it off ,,,,all good stress free fun

 

[Harvest Fields]

get it in writing also get something from gas safe in writing

Good look getting anything from gas safe in writing.

 

[hammers4spanner]

Good look getting anything from gas safe in writing.

I would say good luck in getting anything other than a monthly charge

 

[Scott_D]

Take print outs of why it can't go there.
Get Rep to give proof it can
Keep a copy and leave a copy in each house.

 

[Matt0029]

So the manufactures have said its acceptable. Reason being that the flue is 450mm to the boundary. Which is acceptable if a plume kit it fitted as it takes the 600mm distance from a boundary down to 300mm. The distance between the flues is 1800mm at an angle. Which is greater than the minimum required 1200mm if flues are directed towards each other. So apparently complies with regulations.

Did you get that in writing from them?
