No! The beauty of Regency Direct Vent technology is that you do not necessarily need to go up through your roof to terminate the venting. All you need is proximity to an outside wall, the distance to which depends on the model you choose. Not only does this make installation more flexible, but it also keeps the costs down. And with our sleek and attractive patented AstroCap horizontal termination cap, you won't be cluttering up the outside of your home either.

If you have test data from the outlet of the control device, you can use it to estimate emissions rather than using the model. If you have a limited amount of data, but have conducted inlet and outlet testing, you can calculate the efficiency of the control device and apply it to emissions estimated by the model.

Yes. If this means putting a couple of 45° bends in to get it around the eave, do so. If the vent terminates under an eave, the air from the vent will downdraft over the property possibly causing a urine smell to occur. Ideally the vent should be installed to 2-3 feet above the peak of the roof to prevent downdraft. See similar questions...

There were numerous styles used over the years – all of which are no longer available. The openings measured a standard 14 x 14”, all of which were made by Hehr. The late 1940’s “frying pan” version was replaced in the 1950's with the 2 part baking dish and integral seal, and then again in 1965/1966 with rounded corner slightly domed “Solardome”, a metal framework with plastic panels.

The purpose of the Global JXDM is to provide a consistent, extensible, maintainable XML schema reference specification for data elements and types that represent the data requirements of the general justice and public safety communities. A secondary goal is to provide a baseline model for the data dictionary that can be represented in advanced technologies independently of XML Schema. See similar questions...

This mailing list provides an English-language forum for discussion of topics related to Hayao Miyazaki, a wonderful storyteller and a director of a number of box-office successes in Japan. This list was created in the United States at Brown University in 1991 to facilitate discussion among fans of Miyazaki's works. See similar questions...

It depends on the type and size of the greenroof. Most homeowners could check a flat or low pitch greenroof. A roofing professional should if it is too large or intensive – you can include a maintenance agreement of at least twice per year with the greenroof contractor/greenroof company. Or you can work out an arrangement with the roof maintenance staff of your building. See similar questions...

Yes, although we do not recommend the application of our product by a novice do-it-yourselfer. By following our detailed installation instructions, an experienced do-it-yourselfer can install Springhouse Shingles with relative ease. See similar questions...

Kilns have been operated for years without the newer ventilation systems. Without a vent typically the kiln is vented by propping the lid during the first part of the cycle when the ware gives off fumes. However, a powered downdraft type of vent, like the Vent-Sure that L&L makes, automates this process and improves air circulation and heat distribution in the kiln as well as insures good venting of the fumes to the outside. You MUST be sure to vent fumes generated by a kiln to the outside. See similar questions...

Roofing materials are not restricted. The roof structure is attached to the SRE walls via a metal tie-down rod embedded 600mm into the wall. The mass of the walls ensures an excellent fixing system. See similar questions...

No. We realize that this will make your installation easier, but if the toilet is not installed on its own vent, turbulation of the air in the vent will hamper the airflow, and may lead to odors. In addition, vents connected to other devices (such as sinks, etc.) will start to smell of ammonia. The toilet needs to be on its own vent in order to function correctly. See similar questions...

It means that the manufacturer has submitted the vent unit, properly installed on specific kiln models, to Underwriters' Laboratories for rigorous testing under actual high-heat firing conditions. When installed on Skutt UL kilns, the EnviroVent is the only L listed downdraft vent system. Some kiln vents use an electric motor which may have been UL listed for general room temperature use. This does not make their vents UL listed. See similar questions...

V-300 and Fold-A-Vent product lines have 13.5 square inches per lineal foot net free vent area (NFVA). See similar questions...

The ridge vent should not be used with other roof mounted or gable end vents. They can disrupt the air flow through the attic. A properly setup ridge/soffit vent system does not need to have power roof vents to help move hot air out of the attic. Whole house fans work great with a ridge/soffit vent system. We do not consider them the same thing as the power roof vents. See similar questions...

Take the square footage of house under roof X .48 divide this number by 20 (for V-600 products), by 17 (for V-400E or X-5) or by 13.5 (for V-300 or Fold-A-Vent products) this will give the lineal feet of product needed to meet a 1/150 vent ratio. If you are only going for a 1/300 (code minimum) vent ratio divide the above result by two. REMEMBER there MUST be an equal amount of soffit vent (in NFVA) to balance the ridge vent.

The vent that comes standard in this greenhouse is manually operated. However, it is possible to add a solar opener that will automatically open and close the vent for you as the temperature changes if you would like. You may also upgrade to the large louvered vent used in other Solexx greenhouses if you prefer. See similar questions...
