Hoping someone can advise...

We are renovating our hallway and would like to replace some awful old concertina doors with standard ones. If we do the lounge one, it would open outwards into the hall and sit against a wall which has three vents for the boiler. These vents are in addition to a vent in the front door.

Is it safe to fit a door like this or do the three vents need to be unobscured? We don't want to risk making our boiler unsafe :confused:

THREE vents? Would the door be hard up against the vents, or how much clearance will there be?

The door frame is right against the wall so I guess there would be a 2 or 3 inch clearance...[/quote]


No problem then
 
The make and model of the boiler that you have has a lot of relevance.
The manufacturer will state the ventilation requirements. Having 3 vents in the wall and 1 in the door means nothing without stating the free air space available.
My best advice would be to ask you RGI next time you have the boiler serviced.
 
Three vents may already be contrary to the makers requirements as most need TWO.

Most important though is what vent from the inside of the room do you have to the OUTSIDE to allow combustion air to come in from outside.

When was it last serviced by a competent enginee woul would have checked the ventilation was adequate/correct?

Fair enough, Tony.

OP, DO you have ventilation to atmosphere - it is important
 
Chances are someone has used say 100cm square free area vent at top and 2 100cm square vents at the bottom = 3 vents, to someone who doesnt work in the industry

Its common practice, i see it all the time
 
Sorry for the delay in checking back on here. So we have a vent in the front door which lets outside air in. Is that what you mean?

The top two vents are roughly 21 by 9 inches and the lower one is 21 by 7 so quite big vents.

Strangely enough we can't find replacement covers anywhere so I suspect they comply with old regs? We have the boiler serviced each year by Southern Electric and they're actually due again next week so will have a chat with them then.

Thanks all :)

even without measuring the free through the vents this configuration is not right, open flued boilers require Xcm2 at high level and double that at the bottom, i would suggest a visit from a gas engineer quite soon to check everything over for you including the vent at the front door
