A factory vent damper reduces standby losses.

The integrated draft diverter connects through a 7 in. flue to a lined masonry or approved metal chimney. Steam supply and return tappings are 2 in. NPT and the gas inlet is 3/4 in. NPT, with 12.1 gal water content and 120 V, 60 Hz, 15 A fused power. Protection comes from a probe LWCO, a 15 psi safety valve, a pressure limit control and blocked-vent and rollout switches. An LP conversion kit is available.
