Two thoughts. One a heater burns more hours than a oven or cook top. Two. Most heaters have a higher B T U rating, therefore likely have larger burners, consuming more gas, therefore more exhaust gas for lack of a better term. Exhaust gas also contains solid particles, not just gas. That is why furnaces and heating stoves are usually vented to the outside. Unvented heaters also may be needing more oxygen, with larger burners and if the house is tight it isn't getting enough and then isn't burning clean as it would with sufficient air intake. There may be other reasons, but these seem the most logical to me.

Good question Jerry! And since you asked, I am wondering why my garage natural gas heater smells strongly like gas when operating. The unit is only a few years old, and I clean it out frequently, but I am now getting the gas smell when it's burning. ----- Original Message ----- From: Jerry Richer To: blindhandyman@yahoogroups.com Sent: Monday, February 01, 2010 4:19 PM Subject: [BlindHandyMan] Why does my Propane heater burn so dirty? I have a 100 pound Propane tank outside the house. I have three Propane appliances that run off that tank. They are an ordinary cook stove, an ordinary double oven, and a Propane space heater. The stove and oven burn perfectly cleanly, no smell, nothing, just heat. The space heater gives off smoke, it stinks, and the walls all around the living room where the heater is are darkened about ten feet off the floor. Why do the stove and oven burn so cleanly and the heater so dirty? I know I'm supposed to clean the heater every year. Why is it that I never have to clean the stove or the oven? Thanks.
