Re: [RE-wrenches] Modules over vents

Bruce and All, Sorry, I hit send before I had a chance to complete my thoughts. What I meant to say was that I've found AHJs often allow us to cover cold plumbing vents but I've never tried or had any luck with covering hot vents including condensing boiler PVC vents. Once again, if in doubt you c

Re: [RE-wrenches] Modules over vents

Bruce, I'll send you the CA plumbing code vent section offlist (attachment too large for this list). The way I read the code is that you technically can't cover any type of plumbing or hot vent. However, and I've run into little resistance from AHJs in the Bay Area by covering these. You might wan

Re: [RE-wrenches] Modules over vents

We were given the go-ahead from a home builder whom we are doing lots of work for, to cover attic vents on their roofs, if necessary. These are typically about 4" off the roof. I suspect covering plumbing vents may be ok as well but I'd be doubtful about combustion vents. Did you mean 1.5" or

[RE-wrenches] Modules over vents

Hi all. We're designing a system on a roof that is literally infested with plumbing, exhaust and combustion vents. The combustion vents are PVC and none of the vents are more than 1.5' above the roof. A racking company says that we can cover them with modules, since the modules will be at le

[RE-wrenches] S Facing Mods on E - W slopes

Hello Wrenches, We have an installation where we are putting modules on the east and west slopes of a south facing roof. The roof slopes are 18 degrees. The tops and bottoms of the modules will follow the slope of the roof. There will be 3 rows of modules. I have heard that the shading is di

Re: [RE-wrenches] Watsun problem

Jesse, Have had this happen. Can be a couple things. There are little plastic pieces inside the control box that have contacts. These can be adjusted. You will need to get at the control box and open it. Wattsun can walk you through it. If not they will send you a new controller. Same thing ca

Re: [RE-wrenches] Conduit supports on sloped composite shingle roofs

I'm surprised this hasn't really come up for us. I can't remember the last time we ran conduit along a pitched roof other than very short runs to an eave where we penetrate the roof and soffit to run down an exterior wall. I'm guessing you are dealing with an inaccessible attic. We just about alway
