This usually equates to a median pipe material temperature value of 86 to 100 degree f. The pipe then slips into the hole and is sealed with a high temperature silicone caulk.

You would core a hole 1 4 to 1 2 inch bigger than the outer diameter of the pipe. High efficiency furnace has afue of 87 97 and furnace consists of forced draft condensing low flue stack temperature up to 120 f or 49 c and at least two heat.

Mid efficiency furnace has afue of 78 83 and furnace consists of forced draft non condensing medium flue stack temperature up to 300 f or 149 c and one heat exchanger. These different plastics have different maximum heat service temperatures.

Pitch the flue pipe up toward the chimney. The different types of venting. Should be vented into a cat. If the furnace is a forced draft model the water heater must connect above higher and closer to the vertical flue pipe in an approved manner so that flue gasses go up the stack and not out the water heater draft hood.
