There is a thorough literature on ventilating soffit vents correctly. In CA, many attic vents around the building perimeter are more vertical, like the image below:…Continue

Duct blaster with asbestos?

Started this discussion. Last reply by Glen Gallo Aug 7, 2015. 7 Replies

I'd like to know if BPI has banned the use of the duct blaster in the presence of asbestos ductwork. Is this the case? If there is any documentation from BPI, what/where is it?

Hi, in order to test spillage on an induced draft furnace, the BPI tech specs say to test at the base of the flue. Does this mean that spillage should be tested directly next to the draft inducer inside the furnace? Or does this mean elsewhere?See More

"Monitor the pressure in the vent, if its positive in the vent for more than a minute it is most likely backdrafting. Use smoke at the hole you've drilled to take your CO measurement. When sharing a vent with a water heater check for spillage at…"

"You can stand outside and read pressures. Be sure to have extra hose as you need CAZ wrt outside pressure taken on the A channel, run a hose under the closet door (Input) and another hose to outside. Also you'll need vent wrt CAZ taken on the B…"

"I hope the attached picture is clear enough for you to see.  As the caption on the picture states - There are a surprising number of potential spillage sites on an induced draft furnace.  Basically anywhere there is a connection, joint or…"

Judy Rachel replied to Blake Shurtz's discussion Testing spillage in mechanical closet?
"You open the closet and test the appliance with the door open.  State in your notes that worst case was reached with the appliance door closed (make sure that is the case, often the greatest depressurization is with the door to the CAZ open)"

Ventilating Attics- Rafter Vents

There is a thorough literature on ventilating soffit vents correctly. In CA, many attic vents around the building perimeter are more vertical, like the image below:My question is, how do we baffle these vents while still insulating over the top plate of the wall? It seems like this is very difficult or just plain…See More

"It goes back to the project management axiom: Do you want good, quick, or cheap? Pick one. If you just want to provide some venting with the existing situation, get the bendable foam air channels and live with the marginal insulation at the top…"

"You should go high and low on the roof as Glen suggested.  That would be simple.  You can do turtle type vents low and high.  You can do eyebrows low.  Or you can install a simple horizontal low vent.  From the inside of the…"

"As HERS Raters in California we cannot run tests if it is present per CEC protocols. It is a slippery slope here in the litigious Republic of California. I would error toward caution and if you suspect there is asbestos to not test, have suspected…"

"Based on what I see on the pics you can't really - 2x4 wall with no soffit? The only code approved away is to seal those up & go with a hot roof system which still might not make code for the minimum required"
