cooker Hose

[Polishicebreaker]

I've got to get from 3/8 copper pipe to 1/2" bsp on cooker

 

something like this

then just use a 1/2" female bsp to 3/8 compression

 

 

Is this the normal way to do this?

 

cheers

Broadly, yes. The hose needs to be marked to satisfy the BSS. IIRC it is BS3212 type 2, but check the BSS site or wait for Mike the Boilerman to pitch in.

 

Don't forget the right sort of (thicker) PTFE tape for the threaded joints.

In the house mine had a bayonet type fitting for the cooker are these allowed on boats ?

You would have? isolation valve at the end of run with the hose like

connected to the cooker - not a domestic bayonet fitting

Bayonet fittings are fine (at least according to the BSS inspector who passed mine). The isolation valve is essential though.

Is the point of a bayonet fitting so you only have to screw in 1 end of the hose where as screwing in both ends is tricky??

[MtB]

The point of a bayonet hose connection is to allow the (non-GRR registered) householder to disconnect and remove the cooker for cleaning, then reconnect it afterwards.

(Or so we are told!)

Similar task, my cooker snd water heater are already installed and are isolated by a single cock.

 

Our fridge was located under the captains chair made out if a kitchen cabinet that had been modified (just don't ask ?) fed from a separate bottle, located in a cage off the stern, 'arrangement' i wanted to change.

 

Over this period i had the boat safety certificate renewed, we mentioned our intent to move fridge and asked for advice. Inspecter insisted on a cock was needed to isolate the fridge from the heater and the cooker, we are not talking much legnth in pipe, seemed to me a bit ott.

 

from the cock on the top of the bottle, its about a meter to across a wardrobe to another cock, that then feeds a 'T', one side to cooker, other to the water heater. I could not see why i needed this further cock to isolate the fridge on such a small pipe network.

 

I installed it to save an elongated discussion, just i do like to know the logic or reason behind anything do, because i beleive if you know this, you more likely to put more into achieving it ?

 

BTW, maximum flexible pipe legnth (i eas told)is 1 meter..

All appliances connected by a hose must have its own isolation valve.

[BEngo]

The purpose of the isolation vve for hoses is to help find a ĺeak.

All hoses are permeable to LPG to some extent, though when new, not enough to show up on a soundness test. The extent gets greater as the hose ages, to the point where a hose may be the root cause of a soundness test failure.

If the isolation valves are closed the effects of hose permeability are taken out and, if the system then passes a soundness test a happy punter can go bug some new hoses!
