Pennco Silver 15C-9D 299,000 BTU Cast Iron Natural Gas Boiler

The 15C is available in two sizes from 262 MBH to 299 MBH and is designed for chimney-vent applications. With an efficiency of 84.0% AFUE, the latest design features a Hydrolevel FuelSmart control that monitors water temperature and delays burner start until residual heat has been transferred to the system for maximum efficiency. An integral Draft Hood and Automatic Vent Damper reduces the overall height and footprint of the boiler making it ideal for low clearance/space limited installations.

• 84% AFUE Efficiency: Energy saving features include the electronic ignition system and motorized vent damper to reduce heating costs.
• Exceptional Heat Exchanger Design: Features a dependable cast iron heat exchanger with cast iron push nipple connections. The sections and push nipples expand at the same rate when heated. By using similar materials instead of less expensive gaskets, the boiler maintains a water tight seal.
• Hydrolevel Operating Control: Adjusts the water temperature based on your heating system demand which further reduces your heating costs.
• Water Return/Supply: 1 1/4" NPT
