Residential Gas Furnaces and Boilers - Federal Register

Aug 19 2019 · Exhaust leakage: Combustion products from a gas furnace or boiler are normally vented to remove them from the home. However a potential CO hazard in a home can arise when a path or mechanism exists that allows or causes CO to leak from the flue passageways or vent system of the gas appliance into the living space.

Boiler Cycling Considerations - Babcock & Wilcox

Many fossil fuel-fired boilers are now experiencing load cycling or on/off cycling operation. These modes of operation involve cycling a unit on and off line or reducing loads to absolute minimums in response to varying load demand. This can be caused by daily or weekly load shifts experienced on nights and weekends power generators dispatching units to the grid which utilize a lower cost ...
