I have worked on those furnaces. All those I have seen have an orifice plate in the air intake pipe above the induction fan.
That plate matches the furnace to the site altitude and the chimney
there are also changeable injection nozzles to convert the furnace from natural gas to propane.
Check that your furnace has the correct fuel nozzle first.
The exchange nozzles are normally in a little bag hanging from the piping inside the furnace.
If the nozzle is correct then the air orifice plate above the inducer fan needs to be changed.
IF you need to change fuel type you may also need to change the air flow orifice.
Note that the proper flame condition is for the primary flame ahead of the flame baffle with the furnace at or near proper operating temperature.
Hope this is helpful

Ok, I've done some digging and not found a different jet than the #661024 that is in it. IMO it is huge. The way to change the valve for Nat gas to propane is to unscrew a plug in the valve body, and turn it end for end and screw it back in.
Same jet for Nat gas and Propane according to the manual, but damn that orifice is huge. We are at 2200 ft ASL so it may be ok, or not.

Quote:
7.For Robertshaw gas valves with the regulator
converter(Figure29):
a.Remove the black cover and unscrew the
converter located on top of the gas valve.
b.Invert the converter: for LP the red ring will
be located at the bottom and the LP stamping
on the converter will appear right side up.
c.Screw converter back into the regulator,
hand tight plus1/8 turn.Replace the black
cover on the converter top to protect the
threads
I also have a spare burner I got from the dump, same RobertShaw valve with the same .080 thou jet, but someone was learning mig welding on the burner and deflector so that part is scrap.

Thanks, that is my exact furnace, And my flame is not like that. However it has run 10 years this way. That does not mean it is correct though.

Thanks, I have a similar manual for the M1M. I'm doing inspect and adjust on everything. Always do on whatever I buy. But a yellow flame is not right in my opinion

Was it running on propane for the previous owner?

It has always been on propane, set up that way from the factory.
I am using the original regulators that can from factory.

Default update

Today I spoke with a gas tech in Thorsby, and told him the furnace, model etc and my concerns. He said that is a normal flame. He described it as a big lazy fireball in a drum heat exchanger. He said the parameters are fixed and there is very little or nothing for adjustments, and even changing pressure is difficult.
Then he suggested he should come out and look at it to give it his blessing.
I chuckled and so did he.

Today I had my nephew available, so me and the yellow nigger decided to move the future utility shed into it's new home. Put the forks on and rigging up went smoothly.
This shed is 2x8 construction, insulated with fiberglas, and sheeted in exterior grade 3/4" plywood, inside and out. It was a Electrical room so it has electric heat and was full of switchgear. Built like a brick shithouse.

We lifted the shed and carried it into the spot and prepared and leveled a couple railroad ties the thing will sit on.
I set the shed on the ties and backed up and it started jerking, vibrating, and sounding ugly. So I shut it down.
The double mechanical U joint that couples the Allison to the engine flywheel was taking a break underneath the loader. It was fire damaged and I thought it would be ok, so never replaced it, but I got 4 years out of it.

Maybe I got the same disease as Metelwolf's scooter.

Must have melted out the grease in the U joint.

No, I replaced the grease, but the seals at the edges of the cups were cooked.
