Sounds like just the pilot may be lighting and not main burner.There is no way air can be lown across a burner properly burning and come out cold on other end.

Expert:  airheatman replied 4 months ago.

I am going to open this to other experts.Not sure what may be going on here.It just does not make sense that the blower is blowing air across a flame and coming out cold.
