-The observed pressure of a heating system when it is in an idle or non-operating mode is
called: - -This is known as the static pressure of the system
-The primary purpose of establishing a set of plant safety rules is to: - -protect the workers
and equipment
-What are the four systems required to operate a steam boiler? - -steam, feedwater, fuel
and draft

, -Which of the following statements regarding a hydronic heating system is accurate in its
description?
1. the water circulation must take the water from the boiler and move it through the
individual terminals or heating units where the heat is emitted and then return the water
to the condensate tank.
2. the water circulator takes the water from the feed pump discharge and moves it through
the individual terminals or heating units where the heat is absorbed and any remaining
steam turns to liquid then it is returned to the boiler to be reused again.
3. the water circulator must take the water from the boiler and move it through the
individual terminals or heating units where the heat is emitted and then returns the water
to the boiler to be reheated.
4. none of the statements provides an accurate description for a hydronic heating system. -
