Default boiler flexible oil connection

Hello,

I am connecting my new oil fired boiler to the oil line. This is in
10mm copper but there is a flexible line on the burner. There is
nothing explicit in the instructions but am I right to think that the
flexible line should not leave the boiler? I'm thinking the 10mm
copper should go into the boiler and connect inside? I'm thinking the
flexible line is only to enable you to withdraw the burner from the
boiler for servicing, without having to disconnect the oil? Am I
right?

Thanks,
Stephen.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Stephen
saying something like:

The flexible pipe normally leaves the burner housing and runs alongside
the boiler to meet the 10mm pipe and is connected via a fire valve [1]
but you can if you want, keep it entirely inside the boiler casing. Is
it a kitchen (ie, cased) boiler?

You have got a new type of remote firevalve, haven't you?


[1] The old type of fire valve with the screw head and soldered link is
now not allowed as the only firevalve, but it's good in this application
as a joining piece and provides some extra peace of mind. Don't use it
as a shutoff, though, as the thread strips.

Ah, so we've moved on from the 60's, and my Grandmothers
installation, with a spring-loaded valve and a length of string
stretched trip-wire style across the cellar, holding the valve open? ;-)

I came across an ancient one the other day with pretty much that - a
length of wire run along the top of the burner with a fusible link in
the middle, holding up a weight on top of the valve. It was a much newer
boiler, but I reckon the original valve had been there for ~50 years.

Yes

I would have thought that this question would be answered in the installtion
instructions.

On my previous boiler the flexible hose just connected to the copper pipe at
the bottom of the boiler. There was no support or fixing to the boiler
case.

On my current boiler there is a union on the boiler case. The flexible pipe
attaches to the inside end of the union and the copper pipe to the outside
end. I have a fire valve, filter and non return valve outside where the
supply pipe enters the house.

Thanks for the replies.

It is a kitchen boiler.

To answer Michael's post, there was nothing in the instructions about
where the flexible hose should/should not go. I have been frustrated
with the lack of information about installation; I don't know if it's
health and safety gone mad or some sort of plumber-protectionism to
stop them losing work to DIYers!

I'm afraid I am still unsure whether the hose can leave the boiler or
not. Your post says it can; Michael's says it cannot.

It's interesting you say that. I used to have an old style "gate
valve" fire valve and when my plumber came to service the boiler he
used that to isolate the oil. Thereafter it always leaked. Now I know
why.

This time I went with a 65C peerless model with long capillary that
clips above the boiler. I presume you run the capillary trying not to
crush or bend it too much whilst making it as neat as possible and
keeping out of the way of everything else?

Thanks.

That's a similar set-up to me, except I don't have a non-return valve.
Should I have one? What's to point of it?

My oil line comes through a concrete floor in 10mm copper on the left
hand side of the boiler. Outside, the line is (presumably) buried
under my drive, so I was advised to put the fire valve inside, as soon
as the pipe came through the floor. The problem is, there isn't much
space on the LHS side of the boiler and I don't think it will be easy
to get to the filter to service it.

If I put the fire valve on the LHS, could I run a metre or so of pipe
around the back and along the RHS of the boiler so that I can put the
filter on the RHS, where there is plenty of room? Should I put the
isolating valve next to the fire valve or can that be moved next to
the filter on the RHS?

Thanks.

My new boiler instructions said to install a non-return valve as I have a 2
pipe system.

According to my boiler instructions the filter can be inside or outside, but
as close to the boiler (i.e.shortest pipe run I assume) as practical. You
do need to be able to change the filter. This is normally done by undoing a
nut at the bottom.

The installation instructions for the first boiler in my house (1970s?) said
to locate the fire valve inside. I maintained this situation with my second
boiler. For my new, now 2 year old boiler, I located the fire valve outside,
but as part of the installation I also replaced the oil supply pipes.
Everything that I have read since says that you should have the fire valve
outside! I would be wary of not conforming to this requirement because of
the perceived fire risk.

I just have isolating valves on the tank.
