[HVAC] Clearance for exhaust vent from new furnaceA new furnace had been installed, then a water heater was installed.
To accommodate water heater vent, had to raise connection at furnace which raised common double wall exhaust pipe above roof
Question: how much clearance is need at that point above roof line inside the roof cap? Currently there is about almost 2 inches and this certainly must be wrong. How much should there be?
Thanking you for your comments in advance
