Furnace doesn't light at altitude
The Suburban furnace on a brand new Glacier Peak 5er won't light above 7,000 feet elevation. The furnace works fine up to about 6,000 feet. The trailer manufacturer says it is a "simple adjustment" ...

Yes! At high altitude low atmospheric pressure results in a too rich combustion resulting in a ' flame out' . You will hear and see an attempt to light. Your regulator output pressure or orifice size needs to be reduced to match altitude. When it does light a soft quiet light with a lazy yellow flame shows a too rich mixture. Soot would be apparent.
We have had the obverse effect when going to sea level, the furnace would 'flame out' from too much air. When it did light, it roared like a jet engine, so-- I restricted the air intake a bit with my fingers until I found the sweet spot. then covered that much with tape.
