Problem started last Fall
, when our Duo Therm furnace
was removed to fix a fan problem;to do the fix, and to get at the fan, the furnace
was turned upside-down. Checking the operation of the unit last week, after re-installing it, it was discovered that pilot won't stay lit for more than 20-30 minutes.
Did we disturb some soot or rust particles by turning it over, and if so, what needs to be cleaned out, and using what to do so?
Any help/advice would be appreciated.
