Mend Slant Fin Fin-4 Heating Boiler Thermostats

Slant Fin Boiler Constantly Running?

I've replaced my boiler with a SlantFin Boiler in September 2010. Recently, my boiler has been running even when the thermostats are completely off. Any ideas why?

Could be if you have,zone or check valves stuck open,cir.relay or t'stat or wiring bad.Relief valve dripping to outside.If it does hot water could be you have hot water drip in any faucet.
