Question Gas Boiler Exhaust

I have a relatively new (long story) hot water baseboard gas boiler installed in the garage. The exhaust vent/pipe snakes through the laundry room, outside, and up the side of the house and is capped above the roof.

Aside from the code violations that I think exist (lackluster "heating specialists around here"), one problem is that we seem to get a "bad breath smell" in the garage mostly noticeable in the morning.

I think it is due to poor exhaust or backflow. I am not sure if it is due to the long length (loss of gas bouyancy), or low grade (not sure the rise is adequate for run - through the laundry room), or what else...

In any case, is it adviseable to install some sort of exhaust fan or "draft-inducing" fan? If so, where does one get such an item? And, is it simple to install; for I would expect it would have to be coordinated with boiler operation.

I think a draft fan will cause you problems with the fire. I think you need to have the flue redone properly. I suggest you go to the boiler manufacturer and get a set the of installation instructions. When you or your local inspector figure out what they did wrong, have the contractor come back and make it right. You might also try posting at www.heatinghelp.com and see what they recommend. Rise and length on flues are very important.
