That's a very popular rumor floating around. However, there seems to be a dearth of scientific evidence to support it. Caoihim Connel (sp?), our Industrial Hygienist online has stated this is utter bunk. He said in essence, the Chlorine would need to be in an ionized form but it doesn't so the theory is BS in his book. He's a real smart cookie so I'm hoping he'll chimne in a correct me or state it more clearly.

Now, if you have chlorinated compounds being oxidized, I'd be interested to see the chemical reaction written out. I have always read and been told gas appliances form HCl or stomach acid while oil burners form H2SO4 or sulfuric acid, which is battery acid. Both supposedly can make some nitric acid at high temps along with some NOx but not at normal temps. There again the PEL for NOx is trace level ( I believe parts per Billion).

Nick, I know a lot of mfrs. state in their manuals to keep laundry equipment and household chemicals away from combustion appliances. May just be an unproven theory that has become urban legend.
