Testing spillage on induced draft furnace?

Started this discussion. Last reply by Judy Rachel on Thursday. 1 Reply

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…Continue

What are the current protocols for testing spillage on a natural draft appliance under worst case in a mechanical closet that is too small for a person to fit in? Thanks!Continue

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?

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?

"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…"

"I assume the picture is just an illustration.  If you are building new, then a raise heel truss will provide the required space.  In CA you should also have sufficient overhang for shading, assuming you are in one of the warmer areas. If…"

"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"

Blake Shurtz replied to Blake Shurtz's discussion Duct blaster with asbestos?
"I rarely test asbestos- I just perform a visual on-site. I do not think running the duct blaster would be worse than running the system itself. For this reason, in particularly bad cases, I have recommended not running the system at all until…"
