circulating pump feeding gv90+ boiler with a built-in circulator
I recently replaced a 20+ year boiler with a Weil-Mclain GV90+4. My installer simply replaced the existing boiler with the GV90+4 and did not change any of the existing setup, including a circulating pump on the return...
i have had problems with my fan not shutting off on my furnace(gas) so some one suggested i get a new thermostat. after replacing the thermostat the fan continues to run and i dont know what i should do next. any help would be appreciated. thanks
