csst/drip legs

Thanks, Peter. This will be a retrofitted low pressure propane system sized large enough to serve a range, barbecue, gas log and possible future conversion from heat pump to gas furnace. The CSST will be hung from and attached to the bottoms of the floor joists in the unfinished basement with the apppliances all located on the floor above except for the furnace. In that situation would you still try to slope toward the point where it exits to the exterior/regulator? Thanks. GTM
