If you have any fears of carbon monoxide then you should get things checked. A detector is also advisable for any appliance. They relatively inexpensive but are the only things that will give you any warning (get an audible one!!!!)

System pressure guage on your boiler will rise as the heating circuit gets hot as the water expands. a rough example would be:

when the heating has not been on a while your pressure guage would read 1---1.5

then as the heating came on, and over the heating period the guage would prob rise to over 2 possibly up to 2.5
depending on what pressure is set at when cold.

1 cold to around 2 hot
1.5 cold to around 2.5 hot
