Masport F3000C fire question

melford, Jul 13, 2:50pm
Does anyone else have my problem. Dust is everywhere in the room. Chimney is cleaned regularly, door seal is fine, dry wood burned. No smoke is emitted when the door is opened and no holes in the firebox. Why then does the paintwork particularly the ceiling turn black/yellow? Any clues?

Must be some smoke that escapes when door opened

is it dust/smoke or is it mold ?

definitely not smoke and not mould. Discoloured paintwork from using the fire. Up on the ceiling by the plate it has gone all black and when we received the fire alarm the paintwork underneath was white as it should be. Every morning the fire has ash on top of the grill and underneath the grill there is so much ash. All glass furniture is covered in ash.

start looking for any gaps, cracks. where the flue connects on etc.

ash is either coming out the fire place or flue, or when the door is being opened. you may have enough to draft to pull air through the gap so smoke doesn't come out of it. but when the fire is out air pressure or wind can come down the chimney and blow ash out the gap or even the air inlet. chimney design can influence that.

the only other way is if you have a ventilation system with no filter in it and your pulling ash in via that.

We had soot coming in from the vent holes in the ceiling plate, especially after wind or rain but when we put a new (don't know what its called) cap on top of the chimney the soot problem disappeared.
With the original cap, birds used to get down the chimney so we put chicken wire around it to stop them. The new cap is way better so we don't need the chicken wire anymore and the soot problem has gone away.

We have a Masport F2000 and also find it messy compared to the previous brand of fire we had.
I think that ash is drawn out every time the door is opened, even if it is not visible.
The big problem is that this fire has a very low lip at the front of the firebox, so ash always falls out when the door is opened. Makes a mess on the tile surround. I wouldn't buy another one. Have thought about fitting a bigger lip, but it would restrict the opening size.

Some of the paint discoloration (yellowing) may be just due to the heat emmitted. Like outdoor sun fade but indoors instead. . Heat rises, speeding up the ageing process

The height of the flue top in comparison to your roof ridge may be causing a downdraft when the fire dies down.
Does it happen every night?
Or just on certain wind directions?
