Could it be from salt (sodium chloride) air? We live near the ocean. I read some where that chlorine is used to clean oil from metals.
That comment you made about the manufacturer being located in Houston where they can't use an evaporating oil.....Would they add some type of thermal activated chlorine compound to get rid of the oil after startup? Is a faint smell of chlorine normal?
Oh, one more thing. How did you gain so much knowledge in this field? Are you an engineer? Did you go to a tech school? Got to go to a meeting now. Want to discuss this further, if you have a chance.
Thanks
Back from meeting EDIT: Checked flue odor this morning seems to be diminishing. From what little I know about smogging a car, temperature is critical to emissions? When furnace fan speed is lowered, operating temperature inside HX goes up? Need to do some studying.
Many Thanks
Daniel

Can't say I've ever smelled flue gas that made me think of chlorine... but then I don't make a regular habit of smelling flue gas either. :p
I wouldn't be too concerned about it. Think of all the chemicals in natural gas. Then they cut the gas also with God knows what to control it's Btu content.
Are you getting combustion air from indoors or out?
Not an engineer, just a regular service tech with several years in the field. Always hungry for more knowledge. No tech school. Third generation of my family in the trade though.
I know nothing whatsoever about smogging a car or emissions, but IMO it's best to have a lower temperature rise through the furnace rather than higher, mainly beacuse it tends to create a longer runtime that allows the furnace to reach it's peak operating efficiency. Lowering the fan speed will create a hotter HX. Combustion efficiency (which is practically never as high out of the box as the AFUE rating claims) is more dependant on how much combustion air is being mixed with the gas. I find that most 90+ furnaces draw quite a bit more air for combustion then they need.
