The min/max dimensions for the solid working platform around and beneath the HVAC equipment located in the attic is well defined, but I am experiencing difficulty locating information regarding the material type and thickness (e.g. OSB, Plywood, ½”, ¾”, etc). Would someone please provide me this information as it would apply to the California Residential Building Code. ----------------- [list] [*][u][b]Structure:[/b][/u] Single story residential [*][u][b]Ceiling joists/trusses:[/b][/u] 2” X 4” (24” oc) [*][u][b]Thermal insulation:[/b][/u] Presently none, will be installing mineral wool.

I have a Rheem R96va gas furnace and ever since upgrading to a higher efficiency furnace, there is now too much condensate for my old drain system to handle, as it occasionally backs up and heads back to the furnace (not good!). So I want to install a condensate pump (and most likely a condensate neutralizer, since some of the drain system is pretty old). The furnace is hardwired, on it's own 15amp circuit. I imagine the ideal scenario would be to run another separate circuit for the condensate pump. But...is there any reason why I can't just pigtail off the furnace in the junction box to make an outlet for the condensate pump? Or maybe install an outlet on the furnace itself? I've seen conflicting info in regard to code, safety, etc on this. I'd love to hear your thoughts.
