Definitions for the Act. 1 For the purposes of the Act: "boiler" means a vessel in which, by the application of heat, (a) gas, steam or vapour is capable of being generated and pressurized, or (b) a liquid is capable of being pressurized or heated and includes fittings and boiler external piping associated with the vessel; "boiler system" means a power plant, heating plant, low temperature
The Atmospheric Burner System, the control system and entire boiler are furnished for ease of use and operation by regular personnel. Easy Inspection and Repair Inspection cabinet doors can easily be removed in a matter of minutes, making the internal boiler, drum, tubes, and burners readily accessible.
Each thermostat controlling the primary heating and cooling system should be a programmable thermostat. Hot water boilers that supply heat to the building through one- or two-pipe heating systems should have an outdoor reset control that lowers the boiler water temperature based on the outdoor temperature per R403.2/N1103.2. Equipment Sizing.

Low-Pressure Steam and Hot Water Heating Systems. Hot water boilers heat and circulate water at approximately 200°F. Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low.
