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.

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.

Yes, for any outputs over 5kw rating. It doesn’t matter whether it is a large or small room or whether the room has gaps around, doors, windows or trickle vents e.t.c as it must have a dedicated, permanently open air vent over 5kws.

Do not use small diameter, long vent lines. Use the rule of thumb of the next nominal pipe size every 10 feet (6,1 meters) of vent line and 3 feet (0,91 meters) of vent line for every elbow in the line.

There is no chimney or venting required with an InFlame Fireplace. The Sunjel? Premium Ethanol Alcohol Gel burns clean, free of smoke and fumes and into water vapour, eliminating the need for standard exterior venting. Sunjel? Premium is certified by Environment Canada to be burned indoors without a chimney. All InFlame Fireplaces are also ULC Listed (Underwriters' Laboratories of Canada) for 'un-vented use' to Canadian Government Standards. 9.3-M86 AND CAN-ULC-S610-m87. Back to List

That strictly depends on your personal preferences. Since you will hardly use any cooking oils, the vapors are not laden with fat like in traditional cooking.  All you will produce is a little clean steam while moisture evaporates from the food.

There were over 15,500 dryer vent fires last year. Even though people clean out their lint filter, they don't realize that the dryer vent duct is where lint really builds up and gets clogged. The lint is highly flammable, which leads to dryer fires. Lint buildup make the dryer use more energy to dry clothes. If the dryer is not drying efficiently, it is taking more money to dry and re-dry your clothes.

Yes, it includes a large rear Louvered Air Vent to help bring in fresh air. Add base vents and a greenhouse exhaust fan for the best ventilation.

If a check valve is being used we recommend drilling a vent hole. This hole is located in the basin between the pump and check valve usually a few inches above the pump "on" level but below the pit cover. The vent hole will prevent air locking from occurring (pumps runs but will not remove fluid from tank or basin).

For normal operation with a sealed silo, a fan is not necessary. If the silo is totally sealed, the air from the filling operation can only go in one direction through the dust collector. If the dust collector is too small, or not maintained properly, the pressure safety valve will pop open. But if the collector is sized properly, a fan is not needed.

You need to ensure that the size of the new vent is compatible with your old vent and/or the slot underneath the vent. The best way to check this is to take the existing vent off the window. Vents are usually attached by a series of small lugs that clip-fit into a slot or by two fixing screws. If the vent is clip-fixed you will need to carefully rock and prise the vent away from the slot. When you take the existing vent off the window you will see a slot or two slots cut through your window.

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.

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.

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

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.

Replacement parts are available in selected stores and located in the same area where you purchased your bottle. If you have difficulty finding the replacement parts you need, please contact us.

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.

First of all I try to use a breathable Fabric, if this is not enough there are 4 or 6 Screens sewn into the cover in the vertical reeling area where the covering fabric can be removed , if this is still not enough I can send you some vinyl cowl vents which can be applied on the cover in higher areas afterwards.
