BBU fire front

[stokecity]

can a redundant bbu be left in or do i need to remove and install flue box? cheers

 

[JAP&H]

Thought fire was designed to work via BBU, usually decommission BBU and leave in place.

 

[jtsplumbing]

Same as JAP, you need to drain out BB (Drill holes in boiler) remove burners Etc cap gas, BB MUST remain in place as fire is designed to work with BB,

cheers guys

You'll need permission off manufacturer too. This cannot be done without their consent

I think Baxi aren't too keen on this

 

[AWheating]

there is a gas safe technical bulletin covering this also.

 

[buckley plumb]

i had a glowworm gas backboiler and i called them and they said it was ok as long as i capped gas to the backboiler.removed the union on the gas cock tee and fitted a plug.

baxi wont give written consent for this,they will tell you you take responsibility

 

[broggo]

Def need to drill it out tho. Need to get ALL water out

Gas safe have the TB to admonish them of any responsibility and state you must have Manufacturer consent. As per gas man, it is unlikely you will get written conformation from manufacturer.

If you still chose to go ahead, everything including burner tray should be left in place. Gas to the boiler capped and the electricity supply to the boiler made redundant. Cut off flow and return at heat exchanger and leave open.

Be very stringent with flue flow and spillage tests and label with a decommissioned appliance label.

grahamM do you know TB number?

 

[GrahamM]

Took a bit of looking, but TB 091.

bet that was fun to find dont know why some are saying the boiler heat exchanger needs drilling out though its not needed on a bbu

 

[stokecity]

[SimonJohns]

Think maybe getting confused with a disused solid fuel back boiler unit :smile5:

yep my thoughts too

 

[AWheating]

i would say its being confused with the old solid fuel bottle/bbu. which Hetas now actual say you should not drill and leave but remove all together.

 

[SimonG]

Aye, no more drilling but remove it. Not designed to have fire lit with no water in the solid fuel back boiler.

 

[jtsplumbing]

Was told by GS that any gas back boiler unit had to be drill'd, burners removed, gas cap'd electric diconected, Wish they would make up their mind's

 

[stokecity]

TB 091 doesnt say anything about drilling, it does say burner should be left in and primarys cut back as close as poss and left uncapped
