Suburban Furnace High Elevation Problems
Have an older (20+ years) NT-30SP Suburban furnace that works fine at home elevation of 5,200 ft but won't light at campsite elevations of +8,000 ft. Does this year in and out. At campsite all work...

Had same problem again camping at 9,100 ft. But I was able to fix the problem finally. Bottom line: increased the gap on the ignitor and she fired right up.
Hope this helps anyone else who has similar problem. Note, before I increased the gap, when the unit was not lighting, I could view into the combustion chamber and observe a spark, this was adequate for lighting at 5,200 ft but not at higher elevations until the gap was increased.
