Rickheatdoc :

Welcome to Just Answer, I will do my best to help you solve your problem

Rickheatdoc :

Is this an oil or gas fired boiler?

Rickheatdoc :

If gas does it have a motorized vent damper?

Customer:

Gas

Customer:

Don't know

Rickheatdoc :

You need to check. If you have one you will see a small electric motor attached to the side of the vent just above the boiler. I also need to know if you have a pilot that's lit all the time or electronic ignition

Rickheatdoc :

I need to know if the damper is open and if the pilot is lit

Customer:

All time ...yes, motorized damper . Switched it to held open

Customer:

There's no circulation
