Just another question or two - what kind of exhaust does this furnace have - a standard masonry chimney or a metal pipe? Is it fully inside the house and in a wall or does it exit through a wall? If it has ceramic liners, one could be cracked and leak, but when good heat and flow are established, the exhaust stream moves too fast to leak (or it closes). Metal, even the SS multi wall stuff can leak - elbows and at joints especially.

1. Turn the floor furnace off and give up the idea of trying to repair it or find out what the problem is.

2. Buy a console or wall natural gas heater of the same BTU as the floor furnace I have now, and try to tap into the existing vent work and natural gas line.

Does anyone have a better solution? Thanks for the information so far.
Hotrodman if you want someone to check it out call any one of the propane company's as they usually are the ones that sell/service floor furnaces. I agree with the rest of the guy's I think that combustion gases are getting out of the chamber . We had the same problem years ago in a rental house,cracked heat exchanger that sealed off when it got hot.

I had a floor unit in a house I rented for about 8 years.

If I didn't do this, the odor would persist for weeks. The odor smelled like urine or ammonia, plus a musty odor, probably from dust that I couldn't reach with the shop vacuum. Mice will urinate EVERYWHERE, unless you can find a way to scrub it out you're stuck with burning it out. Mice can squeeze into remarkably small places, don't count them out. If any part of the unit is suspect, get a carbon monoxide detector. These units don't normally burn hot enough to cause much of a chance at flue failure, nor do they put out a lot of harsh chemicals, and can be vented with aluminum flue pipe. This would be a B-vent flue, like a hot water heater, they are pretty durable.

metal vent pipe

The flue pipe for the floor furnace is a 4 or 5 inch metal pipe that travels at a slight upward angle under the house until it gets to a wall near the center of the house and then it takes a 90 degree turn up thru the house and out the roof. It goes thru a closet at one point and it looks like 1/2 inch ceramic pipe which goes up thru the attic and then converts back to a metal pipe as it goes thru the roof. The roof part is about 2 feet tall and is 2 feet taller than anything within 10 feet. I have smelled the pipe in the crawl space while the unit is running and can not smell any odor along the pipe. 100% of the odor is right above the heat exchanger in the house, is so bad you would think there is a hole the size of a basket ball in the heat exchanger, lasts about 10 minutes and then goes away. I have already tried running it for 8 hours sometimes longer on the really cold days we had, thinking the problem would go away but it is still there. As a last resort, I will disassemble the flue pipe at a couple of joints and take the bottom inspection plate off the unit to see If I find anything unusual. It burns with a blue flame the way it is supposed to.

Great suggestion on calling the propane company, I had not thought of that.

Color of flame is mostly blue but has some yellow mixed in

I worked on the furnace almost all day. I dis-assembled the flue that went thru the crawl space and found nothing. I took the plate off the bottom of the unit that is directly below the burner. I did not see any residue on the burners just rust. I took a wire brush the size of a tooth brush and spent about 2 hours cleaning the burner. I shined a light up inside the heat exchanger, then went into the house with all the lights turned off to see if any light peeped thru. There was no light peeking thru anywhere. There were supposed to be 6 screws holding the bottom plate on but there were only 4. Cleaned it all up, re-installed the bottom plate with 6 screws. I fired it up and it has about 50% less odor than before but its still there.

I took special note of the color of the flame, and it is mostly blue with a little yellow mixed in.

Is that normal?

If not, can I adjust it to be 100% blue or is this a job for a professional?

The color is normal. It may get a little more color to it the longer it runs but it sounds like all is well. Do you have any other animals that my be "marking a spot"? I don't know the design of your heater but there may be a chance a cat could be spraying, this would explain the smell persisting.

Finally got a repair man

Don't have any animals at all and it is impossible for anything to get under the house into the crawl space. I have examined the burner first hand and it is clean as a whistle. After calling about 20 people, I finally got a man to come out and look at the unit next Monday. From the description I gave him, he agrees with many of you that the heat exchanger is cracked and seals itself up after it runs for a few minutes. It would have to be a hair line crack because I have examined the heat exchanger from the top and the bottom and can't find a crack or hole anywhere. I will let you know what happens.

Probably not because the humidity sucks, and we don't speak spanish. And who want's to take chances with a tornado that's 100 mi. wide?

2 Professionals could not find a problem with the floor furnace

I finally got 2 professionals out to look at the floor furnace and neither one of them could find anything at all wrong with the unit. One man tried to sell me a picture frame mini heat pump split system. After researching this on line I could not see how that was going to heat and cool the 900 square feet that I had. I have decided to buy a heat - cool window unit, and keep the floor furnace for power outages and really cold days.

Amazing how 2 pro's can't find the problem and instead, 1 try's a sales pitch.
There's been a lot of con's working this year with the abnormally cold winter according to the news channels.
