I took out my old Burnham hot water boiler and replacing with the weil mclain. I two circulating pumps and
relays hooked up to my thermostats. And only one bx wire going to the old burner. I'm going to use the old
circulators relays and need to know what to do to wire the new boiler. The relays will tell the pumps when to kick on via thermostats. What happens to the thermostat wire on the new boiler and what happens to the 120
wires that used to go to the old burner. (the old burner was converted from oil to gas). Thanks.
