Question Does DOE or WAPTAC offer any guidance regarding drilling Type B double wall gas vent pipe to perform CO andor draft tests A The major pipe manufacturers suggest drilling the outer hole larger than the inner hole, and then sealing the inner and outer holes with RTV silicone. B Another possible technique Ive seen is to seal both holes with a stainless steel bolt, with RTV applied on the threads to better seal the inner hole. Is there any combustion appliance testing protocol that recognizes either of these techniques A andor B Answer I am not aware of any official protocol for the drilling of double wall vent pipe. There is something I am wondering about are you actually asking about B vent pipe or are they are they referring to the double wall pipe configuration used for mobile home furnaces, which is technically not B vent, but a piping system where the exhaust gases exit through the inner pipe and the supply air for the furnace passes through the space between the inner and outer concentric pipes Regardless, there is no standard protocol I am aware of. Volkswagen Font Cursive'>Volkswagen Font Cursive. If you are talking about B vent, I think either of the methods mentioned is fine. For the mobile home concentric vent configuration, I prefer using a black pipe threaded nipple and cap that is long enough to span the space between the two pipes see the attached scan here. The cap is in a small plastic bag. A hole is drilled in both pipes. The hole must be the right diameter so that the nipple thread will fit snuggly. Then the hole in the outer pipe is made slightly larger. Put some high temp. Then caulk the outer pipe nipplehole area. Put the nipple cap on when done with test. Wisconsin Wx uses this method. Some state codes, as far as I know, will not allow it. Rick Karg. Category Health Safety. Subject Acceptable garage to home isolation. Question When testing a home to determine an acceptable or unacceptable connection between the garage and living space, does WAP reference a threshold using ZPD For example, if a home is being depressurized at 5. Pascals, is it acceptable if the garage is at 4. On a related issue, is it reasonable to expect a well performing home e. ENERGY STAR specs will have less than a 5 pa connection between the garage to home based on any empirical data Answer To my knowledge, the WAP program does not reference a pressure threshold for the connection between an attached garage and a house, except for the State of Maine there might be other State low income programs I am not aware of that have thresholds.

FURNACE HEAT EXCHANGER LIFE what is the life expectancy of a residential heating furnace or its heat exchanger Typical Residential Warm Air Heating Furnace Heat. If the garage is not able to be fully enclosed, this testing is not required. If the configuration of the attached or tuck under garage makes ZPD testing impossible. For example, if an attached garage is also connected to the dwelling attic space. In such cases, the reason for not testing must be included in the client file. Notice that this Maine threshold is NOT a pressure difference, but a flow 2. CFM5. 0 or less. It is my opinion that thresholds such as this should never be stated as pressure differences because the pressure differences are relative to one another. For example, if the pressure difference between the house and the garage is 4. Pa, the pressure difference between the garage and outdoors will be 1. Pa. The two pressure differences will always add up to 5. If I want to make this example pressure difference between the house and garage look better, I can do so without any air sealing all I have to do is make some new holes in the pressure boundary between the garage and the outdoors. Making these new holes will lower the pressure difference between the garage and outdoors, say to 4 Pa, and increase the pressure difference between the house and garage to 4. Pa. The point here is that NOTHING was done to tighten the pressure boundary between the house and garage, but things seem better. However, they are not. So, I cant honestly answer your first question because I dont think it is valid to use a threshold based on pressure differences, but using flow rates like 2. CMF5. 0 or less between the house and garage is fine. By the way, the Maine threshold or 2. CFM5. 0 represents approximately 2. The second question regarding new Energy. Star home leakage rates to an attached garage is difficult to answer. I am not aware of any empirical studies of house to garage pressure differences or of flow rates between a house and an attached garage. Of course, pressure differences can be measured and they are the first part of zone pressure testing, but testing should always include the second step of opening a hole or door to determine the flow rates between the house and garage.

You Answer Yes, you may us outdoor makeup air through a central furnace or air conditioner air handler to satisfy the requirements for ASHRAE 6. This is usually done by installing a new duct from the outdoors to the return plenum of the air handler. It is best to install a motorized damper in this duct with a control that will close it when ventilation air is not needed. As with most options, there are some advantages and disadvantages with this method. First, the disadvantages. This type of ventilation pressurizes the dwelling when the outdoor air damper is open and the air handler is running. In cold climates, pressurizing a dwelling is usually not recommended. However, pressurizing a dwelling in other climates warmer climates is generally not a problem.
