On Parker Steam & Hot Water Boilers and Indirect Fired Heaters it is inserted in the vent stack between the boiler and the draft hood or barometric damper.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Save up to $785 in the U.S. by enrolling in PD771, a combo course consisting of this course (PD769) and PD770 "Inspection, Repairs, and Alterations of Boilers." Boiler operation is complicated, especially for modern boilers that are fully automatic. Safety, efficiency, and constant generation of steam or hot water depend on the smooth operation of the boiler.

These regulations demand a higher set of energy efficiency measures on new boilers than ever before. With gas-fired heating contributing about 60% of what is spent in a year on energy bills*, these new regulations should save you money in the years to come. All boilers installed from April 2018 will need an ErP efficiency rating of 92% or higher.
Boiler accidents can occur when the boiler is allowed to operate without adequate water in the boiler. Proper functioning low water cutoffs are essential to prevent these types of accidents. Boiler damage can run from severe buckling and deforming of the boiler to complete meltdown or potential boiler explosions.
