Re: [VAC] catalytic furnace

Gas heaters put out three major products of complete combustion. One, of 
course is heat, this is why we use them. The second is Carbon Dioxide (CO2), 
not poisonous, but not what humans are meant to breath either. Always have a 
source of fresh air available, crack a window, etc. The third is water vapor, 
to the tune of approx. eleven (11) gallons per 1,000 cubic feet of gas 
burned. This is an awful lot of moisture to be released inside a confined 
space. 
Now, if your heater is not burning correcty, you can get in-complete 
combustion. The three major products of in-complete combustion are soot, 
aldehydes (a particularily  toxic & nasty-smelling chemical compound) and 
Carbon Monoxide, which is of course, toxic, odorless, tatseless and colorless.
This is why heaters that are vented to the outside are inherently safer than 
non-vented types. Should something go wrong, the fumes will mostly be vented 
to the outside.
