    Smelly combustion exhaust gas

    I have a Trane 5 ton rooftop that emits a strong odor from the combustion blower. The unit is about 2 years old. There is no combustion air restriction and the manifold pressure is correct. Anybody ever experience this problem?

    Not so much on a Trane RTU, but it is usually indicative of a combustion issue that must be discovered and corrected.

    Get your Testo out and combustion test it. Amazing what you can find sometimes, even on a new unit.

    One thing I never got in deep with is combustion analysis. I've decided I need to really get heavier into this. Any of you guys have good links to informative reading and recommendations on what type of combustion analyzer to get?

    You mean in 2011?

    You can send me a PM with company name, etc, if you like. I want to look at the OSHA file.

    I stand corrected .... Guy died in a basement working on a natural gas unit.... He did die from CO poisoning...

    I could have sworn it happened on a roof top... I had a couple really big units pushing thousands ppm of co out before and I still think it would be a bad idea to huff exhaust in that condition ...roof or enclosed space...

    Don't know the company name and don't know his name ... Didn't push my comrade for intimate details...

    No harm or foul intended ... Didn't intend to troll either...

    Sorry for the bad info

    Forgive me for my fault . Again it was not intentional or trolling
