pilot flame keeps getting blown out when on high thermostat setting,have changed low limit stat,gas valve, new water pump drained and flushed system. boiler operates on low stat setting for about 2 hours in one go before going out again-overheating? pilot wont re-light for about 10-15minutes until system cools down. could it be high limit stat? HELP! before i end up changing the whole system.
