Multi- Temp modular gas-fired hydronic (water) heating plants, 360,000 to 2,400,000 Btuh input and larger, consists of individual, self-contained boiler modules, each of which can operate completely independent of the other units. Ideally suited for heavy duty space heating, large volume water heating or a combination of space/volume water heating with an external heat exchanger. Maximum efficiency is attained by step-firing only the modules which are required to satisfy the heating demand. Modules, which are grouped under a single extended jacket, can be arranged in module-banks, side-by-side or back-to-back, to provide a heating plant of almost unlimited capacity.
STANDARD FEATURES:
- Standard cast iron, horizontal section designed absorption units; cast iron domes. Low water content.
- Atmospheric-type, lanced port, aluminized-steel (natural gas) or stainless steel (propane) burners. Insulated cast iron base assembly.
- Extended, insulated gray heavy gauge steel jacket.
- Power vent damper with pre-wired, plug-in type boiler connections (MA-PV).
- Combination gas valve with standing pilot (MA) or intermittent pilot (MA-P & MA-PV). 24-volt transformer to power gas valve.
- Hi-limit aquastats, ASME pressure relief valves, temperature/pressure indicators, drain valves, and draft hoods supplied with modules.
