Boxing a Worcester Combination boiler in ????

[comfortably_numb]

Hi Folks.

I'm hoping to box our boiler in. Its Worcester Combination boiler situated in our utility room.

Is there any regulations in regards ventilation etc that i need to be aware of ?? I've checked the manual but it doesn't state anything

Many Thanks

check the manual again, there is definitely info on service clearances which is what you need to use as there are minimum clearances around the boiler

Probably a room sealed boiler though so no requirements for ventilation.

Not nessesarily, older worc combi's will need compartment vents as per Mi's

not for ventilation but it will need high and low vents to remove the heat

eg 20 kw boiler will need 200 cm2 high and low vent internal

will need 100cm2 high and low vent external

read the manufacturers instructions it will tell you exactly the clearances & ventilation requirements.

at least someone is asking before its fk**d up.

very rare.

Ok .... I have found a set of User Instructions online. The manufacturers requirements & clearances reads as follows

Left-hand side 5 mm
Right-hand side 5 mm
In Front 600 mm
Above Casing (Vert. Flue) 200 mm
Above Flue Turret 30 mm
Below 200 mm

Am i right in thinking that this is for acess purposes, so the cupboard can go as close as 5mm either side, The front needs to allow 600mm (i'm assuming this does not have to be a permanent 600mm but a door opening would suffice so can get front of boiler front off ??)

I'm completely lost on last 3 requirements

Above Casing (Vert. Flue) 200 mm
Above Flue Turret 30 mm
Below 200 mm.


It then goes onto

Ventilation
This is a room sealed appliance and does not require any air for
combustion from inside the house. If the appliance is fitted into a
cupboard or a compartment is built around the appliance after
installation then the compartment must be separated from the
boiler space by a perforated non-combustible partition as
described in BS6798.
Notwithstanding the requirements of BS6798, there is no need
for ventilation openings to be provided in the compartment
because of the low heat loss from the casing.
Do not allow the flue terminal fitted on the outside wall to become
obstructed or damaged.

Can a anyone descirbe this too me in simple English please ???

 

[spacethegas]

access is good.

that all sounds perfectly reasonable.

what boiler is it ?

what is the flueing arrangement ?

i still cant see which measurement is incomprehensible to you ?

these are minimum measurements, greater would be better from my point of view.
