\ American Society of Heating and Ventilating Engineers Guide, 1934 Down-Feed Gravity One-Pipe Air-Vent System In the overhead down-feed gravity one-pipe air-vent system there is no change over the up-feed system in the radiators, the radiator valves, the air valves, or the radiator runouts as far back as the risers.

American Society of Heating and Ventilating Engineers Guide, 1936 -a HEAT EQUIVALENT OF AIR ENTERING BY INFILTRATION The heat required to warm cold, outside air, which enters a room by infiltration, to the temperature of the room is given by the following equation: Hi = 0.24 Qd (/ -- t0) (3) where Hi = Btu per hour required for heating air leaking into building from outside temperature t0 to inside temperature t.
