Boiler burner not igniting for 2nd zone, only 1st zone
The circulating pump is working for the 2nd zone, so why doesn't the flue damper open and burner ignite?
One thing may have contributed...the water was shut off for the 2nd zone while it/pump/thermostat was on. It wasn't until the pump was making a strange noise that I noticed but subsided when the water was turned back on and water flowing through the system. So I can hear the water circulating but the boiler doesn't ignite.
How do I troubleshoot this?
Thanks.
