6.5 COMPONENT REMOVAL PROCEDURE
To remove a component, access to the interior of
the appliance is essential. Isolate the appliance
from the electrical supply and remove the fuse.
And when necessary, close all service valves on
the appliance, remove the appliance casing as
described in section 4.7.1, drain the primary
water content from the appliance via the safety
valve, and drain off secondary water content from
the appliance via a hot water outlet. Ensure some
water absorbent cloths are available to catch any
residual water that may drip from the appliance or
removed component. Undertake a complete
commissioning check as detailed in section 5,
after replacing any component. ALWAYS TEST
FOR GAS SOUNDNESS IF ANY GAS CARRYING
COMPONENTS HAVE BEEN REMOVED

from the compact he manual

and the op`s subject header is titled

Vokera Compact 28

the SE range do not have a drain valve

the HE range do have a drain valve

from info given by OP, he has a Compact 28, so must be an SE boiler

A safety valve should be checked at annual service. If the vlave sticks, it is no loger a safety valve- what you then have is a pressure cooker.

I always drain from the PRV. So what if it leaks- fit a new one. Does not cost the earth but it functions when it has to without rubber sticking to the brass seat and refusing to let go.

The company i work with sub contract vokera we never drain from prv if necessary reagrdless of what anyone says end of.

 

[glasgowgas]

never knew Vokera subbed

any further forward wi the drain valve

 

[fanboy]

On the linea HE range its in the exact same positioning named as " drain valve ", why the compact hasn't this component named the same i don't know, but without arguing to me its a drain valve, and since using it i haven't had any problems with it leaking in any such way.

Glasgowgas, item 31 page 36. This item is fitted with a plastic tube.

 

[glasgowgas]

had a look there Dan, its a new one on me

so why does manual still refer to drain boiler thru PRV?

 

[DP]

I prefer to empty the boiler through the PRV despite what appears to be the general trend. This 'exercises' the valve. If it leaks, it is faulty- I will replace it.

PRV is a safety component similar to ones found on UV cylinders which need to be checked annually.

 

[glasgowgas]

agreed

unless the boiler and its MIs show a drain valve thats where all mine get dumped

you busy DP?

 

[nickso]

i probably shouldnt say this but i use prv's for draining pretty much everything, purely from laziness. 99% of the time the boiler drains to outside in 30 seconds (just that 1% that ****es on your legs or into the ceiling void). more than half of the them seal up fine, out of the 50% that dont most only need a clean.
