.35 ft3-but why are you asking if youve got the answers there?

 

[ollski]

It won't be. By rights it should be 5 times the badged capacity of the meter. A u16 is probably different now though as it has only just come under the scope of the domestic acs with 35mm pipework but is probably still purged like a commercial due to the higher volume of gas. I presume we aren't talking about a medium pressure u16?

 

[doitall]

U 16 is 0.025m³ not that it is of any interest on a diy forum being an industrial size meter.

Industrial gas installers know little details like testing and purging BoB we don't need you to enlighten us.

 

[corgiman]

so we (domestic) can work on u16's now

about bleedin time

And you fell this is a useful way of improving the quality of Corgi registered plumbers do you??

 

[dan the man]

yes domestic are allowed up to U16 now..

as boilers get gigher outputs the need for more gas is making the need for meters bigger.

 

[ChrisR]

gigher watts?

do it all its a peice of cake try this.

u16 meter purge volume = 0.03
so if you had
3m of 35mm copper tube = 0.00252
2m of 35mm copper tube = 0.00168

= 0.0025 + 0.00168 = 0.0042 + 10% fitting allowance = o.oo462

so 0.00462 x 1.5 fitting volume = 0.00693
so purge volume = 0.03 + 0.00693 = 0.03693. easy......................

INSTALLATION VOLUME =......

U16 = 0.025
2m of 1 and a quarter mild steel.
5m of 3 quater mild steel.
3m of 15mm copper. =

0.0022 + 0.0023 + 0.00042 = 0.0087 + 10% fitting allownce = 0.00087 + 0.025 = installation volume 0.03457 cu/metre.

 

[ChrisR]

All trivially simple stuff. No worries there then.

Purge Volume = 0.03693 Wrong.

The flame arrester requires a hose to connect it to the installation pipework. It's volume must be added to the final sum.

 

[dan the man]

flame arrester?

just wait for the smell
