Inquiry (采购产品): air flow switch I am a custodian eng. with the nyc board of education. Iam having aproblem with one of my boilers at my school. I have 2 easco dual fuel burners and after 2 or 3 hours of heating, 1 of the burners cuts out with the display panel stating lockout air flow switch. The burner will not restart until later on in the day,when it will run again for alittle while and then shut down again duem to the air flow switch. My question is what is the air flow switch, and what does it actually do? thank you , steve fassano, custodian. **** Hidden Message ***** steve fassano 8010 12th ave. brooklyn, NY 11228 USA Company: p.s.201 Title: custodian Phone: 7187450425 Fax: 7187450425 E-mail: ck201@schools.nyc.gov **** Hidden Message ***** ck201@schools.nyc.gov
