CLASSICPW 14 Report post Posted January 22, 2009 Im helping another company clean hoods using their equipment, well to make a long story short, it's cold as hell here. Their trailer froze up and now the coil is all clogged up with rust deposits. Anyone know a good way to flush them out? Share this post Link to post Share on other sites
MMI Enterprises 289 Report post Posted January 22, 2009 ..um...turn it on? haha :) Maybe interchange the boiler hoses so it runs backwards to blow it out. Share this post Link to post Share on other sites
CLASSICPW 14 Report post Posted January 22, 2009 cant turn it on because theres no pressure. The coil is clogged, so no pressure no burner kickin' on Share this post Link to post Share on other sites
MMI Enterprises 289 Report post Posted January 22, 2009 (edited) Must be totally clogged up good to where all water is bypassing then. Pressure switch is usually off unloader which is before coil and I would think you could get some initial kick with one of those and a trapped unloader but it sounds like ya got a flow switch or flow type unloader....Regardless, what does burner kickin on or not have to do with anything?. Water still is to go through boiler. Ya said the coil is clogged with rust...why is that? somethin wrong there that needs attention. Hook the 'in' hose of the boiler (the unloader output) to the boiler outlet to see if pressure unclogs it...or try blowing it out backwards with an air compressor.
