You need to slide that handle over to the larger slot and then pull it down or push it up. Ok, good you got it. It was hard to tell from the picture which way it operated. You could try some WD-40 but these dampers are pretty cheaply made and don't have a precision fit. You should try working it back and forth to loosen it up a bit.

Consulting with an HVAC technician advised: disconnect the left duct from the fireplace just below the first floor subfloor disconnect the right duct just above the wye on the first floor route the furnace + water heater duct to the left duct using 6" round B-Vent.

Instead of building a new chimney I replace the old removed flue with 10 inch inside diameter stainless steel triple wall insulated stack piping inside of a tall chase. I built the chase much larger than your proposed 12"x12" size. My chase was, ...

Have someone go outside and you tap on the wall I bet they can find the spot proving it is the exterior. That is some what unusual but I would at least check that before going further.

With 3/4" material screwed to it it will be crazy strong. stronger than those engineered beams that only have 1/4" material for the web. Talk to the flue installer to see if they want it fully enclosed or only 3 sides enclosed for the install.

There's a double layer brick wall between the two residences and the chimneys tied into this. It looks like when your neighbour's chimney was removed some of the bricks in the wall were disturbed and then replaced slightly crooked. crooked bricks look untidy, but are not signifiantly weaker than perfectly aligned bricks. If there were cracks, that would be a ...

Normal settling cracks, would not be worried about it structurally. But... Is it sleeved? Is there a metal pipe inside the chimney? Most municipalities now require you to sleeve a masonry chimney that is carrying CO2 or any other potentially dangerous gas that might leak into your house. Even if you can’t see the cracks, they are there. By running a metal ...
