Been chasing this issue for a few years.
stove works great at temps.mid 40ís and up, but colder temps 20ís to high 30ís it struggles and wonít be lit.
Tank is full, Weighed it, changed regulators, blew out the lines and manometer tests normal pressure at home and higher temps.
Last week camping in the snow with temps slightly below freezing it worked fine the first day, but slowly diminished, then would not light
When it did it went out as soon as a tea pot was put over the burner.
Tried different propane
suppliers, thinking I was getting watered propane
or too high a butane mix,as well as 3 different tanks.
Just put a new regulator on hoping it would solve it, but same story when it gets cold.
I think it should be good down to 0 F , at least.
Thinking my regulator(s) have been freezing up, but havenít tried the hot water remedy over the regulator. Reg. Vent is pointed down.
Any ideas would be welcomed!
