Welcome! Here are the website rules, as well as some tips for using this forum.
New to the forum, hoping you can help clear my confusion. Quick background, I just moved to a new old house with steam heat, I grew up with forced hotwater. I had an older Burnham oil-fired boiler that seemed to take on more water every few hours during heating cycle which I thought odd. It had auto feed, obviously. We decided to switch to gas since old boiler was on it's last legs. Plumber first told us we needed chimney liner because we were switching to gas & flue opening needed to be moved to same height as gas water heater flue pipe. Two chimney sweeps also said I needed liner (One felt he couldn't fit a 5' liner, he wanted to install smaller one, plumber said forget it). Anonymous call to city inspector also said we need a liner if switching to gas, he recommend direct vented boiler. So now I have new gas-fired steam boiler with old flue opening & no liner (No C02 alarms triggered on any floor). Also plumber did not re-install auto feed. I am concerned with how often I'll have to check water level & how to add water as well as how to flush water weekly/monthly? Should I have auto feed installed? Should flue pipes be level? Do I need chimney liner with gas? Any help, advice guidance will be most appreciated!
P.S. Forgot to mention, plumber used some copper on steam supply between iron-I thought that was a no-no?
