does gas hob need rigid connection?

[bluesky]

hi all, i am in training of gas safe, one plumber told me that gas hob should use rigid pipe, i know gas cooker can use flexible hose for connection but really not sure about gas hob...

cheers

 

[franky]

gas hobs should be rigid and with a isolation valve

 

[paulnwales]

rigid pipework, plus its much neater

 

[richw]

rigid, unless otherwise stated in MI's

 

[kirkgas]

it actually says in BS6891 that a flexi can be used unless otherwise stated in the MI that a rigid pipe must be used, it further expands that if a flexi is allowed it needs to conform with BS691 (I think it is this one) which says the flexi should not come in contact with a surface over 70 degrees C or subjected to damage from drawer runners etc

Rigid pipework plus means of isolation.

 

[AlexGas]

Here it is:

BS 6172

11.1.3 Unless stated otherwise in the manufacturer’s instructions, a gas hob shall be connected to the
termination point by a rigid fixed connection.
11.1.6 Where rigid pipework is used, an isolation valve with means of disconnection shall be provided.

rigid yes cooker hose no for a start it will be unlikely it can hang in a loop,secondly if its a built in oven under the hob it will touch it and melt and its so rough its like cowboy territory so cooper with a gas quality isolation valve the ONLY way to do it

 

[stevetheplumber]

the thing that amazes me is were suppose to keep wires away from gas pipes and on a hob they are allowed to come out adjacent they should be on opposite side of the hob

and dont bend pipe work like i saw on the last magazine we all had

Kirk is using a different British Standard when he says "it actually says in BS6891 that a flexi can be used unless otherwise stated in the MI that a rigid pipe must be used,".

I think that I will stick with BS 6172 as thats in line with my recollection and I dont want to leard new tricks unless its absolutely necessary!

it is a typo by me, the quote is correct but as you say it is from 6172, (BS 6891 is for installation pipework)
