Gas oil

[P J F PLUMBING]

Hi guys I'm really stuck. I priced for a job to replace a boiler running on gas oil. Red diesel I am replacing it with a SE warmflow floor standing combi to run on gas oil red diesel It's in a factory so it's excempt from being HE . Can I come off the back of the boiler and discharge at low level ??? Also do I need to drop a nozzle size or jiggle the pump pressure I'm really confused I've fitted HE boilers on 28 second but this is the hardest one I've tried to do many thanks in advance Pete

Yes, just make sure you've a cage around the terminal to prevent people burning themselves

Also do I need to drop a nozzle size or jiggle the pump pressure I'm really confused I've fitted HE boilers on 28 second but this is the hardest one I've tried to do many thanks in advance Pete

I've put the SE manual in my drop box, I'll pm the link to you in a miute, look at page 28, all there for you buddy!

If burning gas oil the flue must terminate at least 6ft from ground level.

Where did you get that from?

[kimbo]

Where did you get that from?

Standard training when I used to fit boilers for farmers.
All the manufacturers will tell you 2meters min for balanced flue, Worcester say only on a conventional vertical flue on their old boilers.
Can my boiler burn 35 second Red Diesel fuel? - Worcester, Bosch Group UK installer site.
Also Oftec technical book three says 2 metres min for balanced flue.

Ok really confused now the really old one that's there is vertical flue the new one I'm hoping to put though the wall and discharge low level with a cadge its going to discharge into the factory yard by the docks help now please very lost with all this

 

[kimbo]

No confusion you cant do it.

Page 5 says you cannot use the low level flue supplied and the flue gases must terminate at least 2m above ground level.

5" Stove enamel.

 

[P J F PLUMBING]

All the way up ?? Sounds expensive ??

 

[SimonG]

How high you going?

 

[P J F PLUMBING]

It's in a factory about 9 meters I'm really stuck had a huge price for S IL HELP

 

[SimonG]

Ouch!

 

[P J F PLUMBING]

Can I call you pls

 

[SimonG]

You could if the phone wasn't in the van. Left it in there tonight and it's absolutely chucking (had to be careful there, thought we were in the arms ) it down so it can stay put for a while.

I've always used a couple of lengths of stove enamel to get it up high enough and then out through the wall.

Don't know if you could use 1 length of stove enamel and then onto a stainless flexi flue and up. Then box in the stainless with some concrete board using metal studwork? Never had to get something that high as 99% of mine is domestic.

 

[P J F PLUMBING]

[Dotty]

Use a 300 - 500mm si as a starter piece then adapt into class 1
