Nope, these units require a permanent air supply from outside as per the manufacturers instructions.
The circulation fan can affect combustion in poorly maintained warm air units.

On the unit I have seen the burner sits at the bottom and inside the heat exchanger which is not sealed from the rest of the unit. I take it the warm air dosent come into contact with this then. Thank you.

Why are you asking.??
It doesnt, and if it does the appliance is immediately dangerous as the heat exchanger is cracked.
Why do you ask?
If you have any doubts get an RGI to check it pronto

Why go to trouble of posting on net when you could ask the guy there and he could show you how the two air flows are seperate
Yes I am, but from what I ve been told theres not much use for them now but just interested, cant seem to find much info on them.
Think you'll find it's DAH1??
Most important with warm air is that the combustion air and the circulating air are separate and don't affect each other.
Old units didn't keep the separation well enough and were declared AR and had to be altered.
Big numbers were put into town houses and council flats, though many of them were poor quality installations and have been replaced.
"Warm air" is implemented better in some USA systems, which can filter the air to hepa levels, recover heat from air changes etc.
