EDR-IOM-2014-0318

Perform Test of Limit Controls

Fire the boiler and test the high limit control as follows:
1. Alter high temperature limit to a value lower than the anticipated loop
temperature. Turn the boiler on. Water temperature will rise until the
boiler locks out. This condition has to be manually reset.
2. Alter the high limit cut off temperature to normal level, typically 10-20
degrees above set point.

Perform Test of Low Gas Pressure Switch

Test the low gas pressure switch as follows:
1. With the boiler running turn up the low gas pressure switch until a lock out
is annunciated.
2. Reset the switch to normal level, re-start the boiler.

Perform Test of High Gas Pressure Switch

Test the high gas pressure switch as follows:
1. With the boiler running turn down the high gas pressure switch until a lock
out is annunciated.
2. Reset the switch to normal level, re-start the boiler.

General Operation of the Boiler

Excessive cycling will reduce the useful life of any piece of mechanical
equipment. Endura boilers should be operated and controlled so the boiler
cycles less than 12,000 times per year. Endura boilers should be operated and
controlled so that the temperature diff erential across the boiler does not exceed
100°F (38°C).
