See boiler pictures below of system I inspected today. Need some help.
- Is this in fact steam boiler or just water? Contractor stopped by and said Steam? I did not see any water gauge if it were steam but not sure?
- Should the relief valve have proper extension?
- After running heat for 30 minutes thermostat set at 80 deg. I shut off and the pressure guage is almost 250 D?
- Should exhaust flu be better sealed per picture?
- anything else I missed? Unit fired fine and flames were blue with little orangish tips…
Thank you for any help!!!
