: I AM HAVING A PROBLEM WITH A NOISE THAT SOUNDS LIKE AIR IN THE LINES,BUT IT IS NOT : THAT BECAUSE A PLUMMER CHECKED IT. HE COULD NOT FIGURE OUT WHAT THE PROBLEM WAS.THE NOISE : ORIGINATES AT THE BOILER, AND BECOMES INCREASINGLY LOUDER AS THE BOILER STARTS UP. : THE NOISE WILL GO AWAY PERIODICALLY.IT STARTS : LIKE A HUM AND THEN GETS LONGER AND LOUDER : AS THE BOILER HEATS UP. ANY HELP WOULD BE : GREATLY APPRECIATED.IF ANYONE HAS A MANUAL : FOR THIS MODEL, COULD YOU POSSIBLY FAX ME : SOME PAGES SO THAT A LOCAL PLUMMER WOULD : BE ABLE TO POSSIBLY FIGURE THIS OUT? : THE COMPANY:HYDRONIC TECHNOLOGY,SHREWSBURY,MA. IS OUT OF BUSINESS. : THANK YOU.WARREN your problem is probably scale build up inside the boiler. this can be removed with a boiler descaler it comes in liquid form .its avaible from most plumbing wholesalers. or you can use ice machine descaler. another thing it could be is the impeller on circulating pump is worn and not putting enough water through the boiler. noise from scale comes from water turning to steam inbetween scale and the boiler heat exchanger and gets worse as temp. rises any more questions e- mail me [email protected]
