The improved Series MI™ residential, cast iron, hot water boiler is fully packaged and ready to install. This atmospheric, gas-fired boiler is designed for natural draft use with a conventional chimney. The Series MI™ boiler is available with either standing pilot or intermittent ignition, and is available as natural or LP gas. The integral draft diverter provides a low-profile design, allowing the boiler to be installed in areas with low clearance. Standard Honeywell controls are easily accessible, making the Series MI™ boiler simple to install and service. Standard equipment includes a Taco circulator, a flame rollout safety shutoff switch and a vent safety shutoff switch.
211A™ boiler efficiencies are compliant with federal and ASHRAE 90.1 requirements. Optional Mod-U-Pak unique three-stage firing system provides improved boiler response and fuel economy. The built-in horizontal to vertical draft hood and aluminized steel flue collector provide a low boiler profile to allow installation in areas with low head room. The unique finned, tubular sections are spaced evenly using spacing rings which allow the sections to maintain their as-cast skin, providing maximum corrosion resistance and longer life.The Peerless® Flow Port flexible seals assure a water-tight fit while providing faster boiler assembly and allow the sections to expand and contract independently. The exclusive Peerless® access design, from both ends, allows easy accessibility to the flueways for inspection and cleaning, without removing the entire jacket. Also, optional tankless coils can be used to assure adequate domestic hot water production on water boilers only.
