Fuel‑Saving Ignition & Vent Damper The boiler’s electronic ignition fires only on a call for heat, and the motorized vent damper helps reduce standby losses compared with older standing‑pilot designs. Flexible Left/Right Piping & Wiring Water, gas, and electrical connections can be routed from either side of the cabinet, making replacements cleaner in tight mechanical rooms. Low‑Profile Draft Diverter The integrated draft diverter lowers overall height, so the 15B‑150K fits low‑ceiling basements where external draft hoods are a challenge.

The 1‑1/4" tappings support common residential manifolds and near‑boiler piping layouts.
