You need good ventilation so the fire can draw air in. Check your airbricks
are not blocked. This may well happen if you have full double glazing which
effectively seals the house.
I guess you can test this theory by lighting the fire then opening an
outside door or window in another room. If the fire then draws correctly
it's a ventilation problem.
The other time this can occur is in windless conditions when there's no
airflow over the top of the chimney.
Finally, you say it's a gas fire chimney, it may be too narrow to permit a
good enough flow of air/smoke up the chimney for an open fire.
It's driving me mad trying to remember what this effect is called. I know
they use the same method inside car exhausts to get rid of the water in the
bottom of silencers.
It's some thing like the 'peeto' effect?
Answer on a postcard, put me out of my misery.

Are you sure that the fire is directly underneath the chimney? We find that
untill the fire gets going and the chimney warms up then sometimes you can
get some smoke in the room. Make sure there is no draugh blowing into or
across the fire.
Yeah, try holding a newspaper across fire opening (like my Dad used to do
and scare us to death!) until a decent amount of smoke has gone up chimney.
Once you get the flow going it might be better.
Otherwise, I think it is a bit of a dark art getting a chimney to work"
When I opened up the fireplace in my 1900 house some years ago I had the
I resolved it by building (bricks, mortar and angle iron!) a throat or
constriction (not sure what the corrrect technical name is) at the bottom of
the chimney and just above the fireplace. The theory is that as the hot
smoke and gasses rise up through this throat they then expand just the other
side of it hence creating a low pressure area which then sucks (or draws)
the smoke up.
We get a little smoke when first starting the fire, but it then very quickly
gets sucked out.
As already stated, the room needs adequate ventilation so that the fire can
It worked for me - hope this helps.
