易用的气壁炉插入物
Kim North-Central Alberta|Posted in一般的问题on
In the winter (Alberta) we get huge drafts coming in the grills of our gas fireplace insert. I’ve noticed it when it’s not in use, especially at night but it seems inconsistent and not necessarily predictable by the temperature or audible wind. From the outside there is a fresh air intake on the chimney and there is a metal chimney exiting the top of the old stucco chimney.
我可以在这里做什么？我什至打电话给谁看？我的丈夫喜欢壁炉，但我真的很担心在这里的选秀时间为-30 C，我们的冬天很长。

我们一直在做房子天然气插入fireplace, and a LOT of air was coming in through the sheet metal housing when we had the blower door running. This is a direct vent unit with a single pipe out the top and through the roof. We went up in the attic and could see that the builder had framed a chase for the vent pipe, and had put a plywood ceiling above the unit, but had cut a very large hole for the pipe, and not installed a sheet metal draft stop. We were able to install one at the attic floor level by cutting a clean hole in a piece of sheet metal, cutting it in half, then installing it around the pipe. This is allowed by the manufacturer of this particular pipe system, in fact they make parts you can buy for this purpose if you want to. The other thing we did was to make sheet metal caps to cover a couple of large holes in the housing, in the space below the burner. These holes are punched by the manufacturer so that the plumber and electrician can run the gas and electrical connections without drilling the housing. We got a lot of improvement on this one but it is hard to make them perfect.
As far as who does it... a sensible HVAC contractor, a building performance contractor, whoever is in your community that is fluent with this stuff. The average contractor probably is not.
我们是对现有壁炉烟囱的改装，我不确定我能从阁楼上看到。原始的内部通风孔被填充，并使用钣金装在插入物周围的其余空间中。由于某种原因，他们将其设置在砖炉膛上方几英寸处，因此在所有四个侧面都有钣金，而不会在内部边缘填充，并带有几把螺钉固定在上面。不确定我此时如何去烟囱？
我注意到房子外面有一点灰泥在一个底角（它像悬臂一样坐在）上，所以我想知道这是否是问题的一部分。
金，
必要的步骤是热信封任何部分所需的空气密封步骤。但是，许多建筑商忽略了金属壁炉后面的这些步骤。一旦安装了壁炉，通常就没有很好的方法来解决问题，而无需删除壁炉外侧的壁板。
当然，每个安装都是不同的，因此很难评估如何在不进行现场访问的情况下进行。这是一篇文章，其中包含有关空气密封壁炉壁ches的更多信息：

There must be home performance contractors, insulation/air-sealing companies, even clever HVAC people in Alberta--it's cold up there. Finding the right person is key. If they don't own a blower door that's a bad sign. If they do, they would set it up right away and start figuring out where the air is and where they can stop it. Martin is right, it can be hard, but if there's good news, yours sounds like a retrofit so it may be possible to modify the installation. Once they're installed in new construction it's hard to change anything.
不幸的是，烟囱外部有灰泥，不壁板，因此不能轻松地将其拆除并更换。我认为穿越外部会很昂贵，因为我需要在整个烟囱上重做灰泥。将壁炉拆除并重新安装（或更换）是更好的选择吗？我们尝试用磁铁阻止格栅，但没有使用磁铁，但我什至无法做到这一点，因为控制面板格栅下的底部不仅是前部。
冷空气是否有背景风险？即使被磁铁和枕头挡住，也可能是一大量的冷空气。
You would think houses in a climate that can be -30C would be well sealed (or at least well insulated), but not so. I live in a small town 1.5 hrs north of any major cities. So while I'm sure there are lots of really thorough insulation and air sealing contractors I don't really think that I have access to them. Whoever did the original cellulose upgrade to only the upper attic (homeowners?) put it right up against the furnace chimney so I'm thinking they weren't qualified and I'm glad we haven't had a fire :P The best part is that my home inspector didn't catch it.
我不知道,金,但我住在一个非常小的和remote community and there are a handful of us here who do the type of niche work that you need. It's all a matter of digging hard and working your network to find who you need. The fact that there was some hack work done in the house doesn't mean there are no good tradesmen there.
You may also have one with the "triple wall" chimney that is designed to be cooled by allowing air to constantly flow from the open area above the metal fire box to the exterior.http://inspectapedia.com/chimneys/0998s.jpgthese can be impossible to remediate without replacing the entire system.
迈克尔，OP指出，这是一个燃气壁炉。该排气系统是否可能还适用？
I don't doubt that there could be good tradesmen that will work here. I have only lived here a year so I don't have much of a network to work yet. The business that it supposed to do our attic insulation is someone I know personally and was recommended by another friend who is a contractor. We also know a few guys with plumbing/HVAC companies I could ask but they tend to be super busy.
我的阁楼是我在这里霜冻之前的优先事项，但是壁炉里有这么多空气，我想知道是否应该先解决这个问题。绝缘材料本应在本周晚些时候发生。
金，
Correct me if I am wrong but you have what is likely an old masonry fireplace and chimney with a gas fireplace "Insert" installed into the existing wood burning fire box?
如果这是正确的，那么您的问题是不幸的。
请告知，我将尝试提出建议。
你好，
我想复活这个线程。希望金得到答案。我想听听她能够找到/修复的内容。我有同样的问题，但我增加了一些皱纹。我肯定在燃气管线进入壁炉附近的空气流动。我有两个壁炉。一个用于地下室，一个用于主层。我也有一条烟道。如果我有直接的排气壁炉，为什么我要有烟道？我也知道，壁炉后面没有绝缘材料，因为当我透过巨大的孔中的燃气线时，我可以看到OSB。 Few questions, is there a way to know if I can remove the Vertical flue? What are my options for insulating behind the fireplace?
