having trouble with 1,100,000 btu steam firetube boiler with conversion burner.Boiler operated fine all winter had trouble in fall and it is acting up again now. When boiler shuts down on pressure or stat is satisfied, occasionaly the pilot goes out.Draft is between 2-4" but jumps up to between 10-20" when it shut down
