proper slope for furnace vent piping

Venting question First the furnace: The 1/4 slope is for the intake, not the exaust pipe. There is no mention of specific slope requirements for the exaust pipe, other then sloping upwards (there is a drain for the exaust blower comparment in the furnace).

Condensation in dryer vent I think that the pipe is angled downward from the room where the dryer it since it is about 8 below the surface with 90 degree elbows being used to raise it up and turn the pipe back horizontal. I have a louvered vent cover to prevent water/animals from entering the dryer vent.

Why are actuators used in directional control valves? , works at Jacobs Engineering. In many processes the fluid is allowed to flow only if a certain amount of fluid is build up upstream of the directional flow valve. These valves are operated by actuators which sense the pressure and open the flow. Being a directional valve they obstruct the reverse flow. Such kind of valves are mostly followed in pumps discharge.

- Irradiation by sunlight, seasonal changes, and day-to-night transitions can. impose a significant effect on any piping material installed above the ground. As a general rule, PE pipe for pressure applications can be safely used at. temperatures as low as -40°F (-40°C) and as high as 140°F (60°C).

About Attic Ventilation Rafter vents ensure the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through the gable or ridge vent. To install the rafter vents, staple them directly to the roof decking. Rafter vents come in 4-foot lengths and 14-1/2 and 22-1/2 inch widths for different rafter spacings. Rafter vents should be placed in your attic ceiling in between the rafters at the point where your attic ceiling meets your attic floor. Once they are in place, you can then place the batts or blankets, or blow insulation, right out to the very edge of the attic floor.

90% Furnace venting 90% Furnace venting. Posted on August 22, 2012 by Andy. With these higher efficiency furnaces, came some other considerations. The 90% implies that 90% of the heat that is put into the furnace is transferred into the duct system and subsequently into the homes living space leaving only 10% going out the exhaust.

What is a Downflow vs. an Upflow Furnace? An upflow furnace creates heat by taking the air from the bottom area of the furnace. And then heats the air and pushes the warm air from the top portion of the furnace. A downflow furnace works in the opposite way. This specific type of furnace takes air from the top of the furnace, heats it and then expels it from the bottom of the furnace. Homeowners that have an upflow furnace are required to place their furnace in the basement of their home. This is done so that the heat can efficiently rise to the many levels of the home. On the other hand, a downflow furnace is always placed at the highest point of the home.

- A vent must rise vertically until it reaches an elevation of 6 above the flood level rim of the highest fixture served by that vent before it can be run horizontally, which in the case of a watercloset (toilet) it would be 6 above the rim of the bowl.

- Roof penetration of the vent and intake air piping should be such that the combustion air intake is a minimum 12” (30.5 cm) from the adjacent vent pipe of the other water heater. For installations in the U.S. refer to Figure 16. For installations in Canada, refer to clearances required by CAN/CSA B149.1.

Installing Eave and Ridge Vents A vented drip edge is effective when there’s no room for a soffit vent—and handy for retrofits where you don’t want to disturb the existing trim. You also can add this to a conventional soffit to boost the inflow capacity.

MIKE HOLMES: Proper venting important for plumbing to work A cheater vent (or air admittance valve) is a vent that comes off the fixture -- for example, a sink in a new powder room -- and is buried in the wall. They're called cheater vents because you and your contractor get to cheat a bit on the expense and labour of the plumbing job.

- Proper ventilation is an important part of a plumbing system. Every plumbing fixture, from a toilet to a shower, needs to be connected to ventilation piping. The pressure of outside air drawn in from ventilation pipes helps push waste or used water down through drain pipes. Vent pipes also lead through a roof to expel harmful gases or unpleasant odors from a home. Try these steps to vent plumbing.

Masonry Chimney Construction Guidelines All masonry chimneys must be terminated with a cap that is 2 inches thick (minimum), extending 1½ inches away from the chimney wall with a drip edge. All caps must be center reinforced with ½ inch (min) galvanized hardware cloth. The top slope of the cap should be 10 degrees away from the flue liner.
