Pennco 1609HSID in practice
The Pennco 1609HSID is a cast-iron gas-fired steam boiler rated at 299/280 MBH input on natural gas/LP. Its row in the 16 Series sell sheet prints 245/229 MBH heating capacity, a 184/172 MBH AHRI net steam rating at a 1.333 piping and pickup allowance, 766/717 steam square feet and 82% AFUE, with a 7" flue, a 30-3/4"-wide cabinet and an approximate weight of 736 lb.
The boiler ships fully assembled with an insulated jacket and a completely installed and wired gas control system: titanium composite burners, a gas manifold with orifices, an automatic redundant combination gas valve, intermittent pilot control with continuous retry and 100% shut-off, a combination pilot burner/electrode/flame sensor and an integral draft diverter. Standard equipment also includes an electronic low-water cut-off with 3/4-inch probe, pressure limit control, steam pressure gauge, glass water level gauge, blocked vent spill switch, flame roll-out fuse link and a 15 psi ASME pop safety valve. Ratings are for sea level to 2,000 feet with a four percent reduction per 1,000 feet above that.
Boilers.ca documents this size at model level from the sell sheet and links the published IOM and near-boiler piping guide. Steam, gas and venting work belongs with a licensed contractor. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'.
Best suited to
- 299 MBH residential steam loads (natural gas)
- Systems needing about 766 square feet of steam radiation
- Homes with an existing chimney and a 5- to 7-inch flue
