q on baro damper and smokepipe

smp74 Member Posts: 61
Is it ever acceptable to have the damper on the end of a T like that? The pipe is crooked and the damper isn't even close to being level. Shouldn't it be on the side of a T directly on top of the boiler then an elbow to the chimney? Also, how's the use of a backwards flex adapter to join the two pipes? There's a good 1/2" gap in there on the boiler side.

    Oil fired. Burnham. Installed in 1999. I think the model was PV7xxxx and input ~1gph, 3 sections with tankless coil. Don't have a good pic of the data plate. Replaced a snowman.

    please tell

    Please, let me know if you guys see anything else good / bad / ugly. I don't know squat about steam systems. Saw this at grandma's house at thanksgiving. Some stuff didn't look right so I come here to query the experts.

    OK, got two contractors lined up to look at the system later this week and evaluate / get estimates. Any input from the wall would be great so we can have a more informed conversation about the system and see that specific issues are addressed.

    If the system as a whole is indeed an abortion, I am most interested as to why that is so.

    First should get a Level II inspection on the suitability of the chimney itself. I don't see a cleanout btw. A bullhead tee is used for gas but not oil. The connector should meet NFPA 31 and NFPA 211 requirements, which means proper gauge/ material, joints secured, etc. The barometric damper should be installed per the mfrs. instructions. A Field Controls RC damper for example has different positions for the counterweight for horizontal versus vertical placement. The damper must be level in order to function as designed. It should be located close to the appliance collar but at least 1.5-2 duct diameters away from the appliance collar or any ells or tees.

    That boiler is too close to the wall. Rest of pics not too clear.
