3.A minimum of 6 pipe diameters of straight pipe shall be installed upstream and downstream of all closely spaced tees.
4.The minimum pipe size for connecting a Super Stor water heater is 1 inch.
5.The minimum pipe size for connecting a Munchkin boiler shall be 1.25 inches and 2 inches for the 399M.
