I'm replacing a 100 year old cast iron gravity flow boiler with a Weil-McLain condensing boiler. Reading thru the specs, the boiler components and accessories seem like they might be sensitive to left over rusty black crud in my radiators. Any idea where I can purchase a filter that will remove this stuff and where would be the best place to install it.
