INSTALLATION AND OPERATION INSTRUCTIONS

5-4

HC SERIES BOILERS  

HC 13-50, HC 15-95, HC 15-96, HC 20-125, HC 33-160

11.

 Restore water pressure to the boiler.

12.

 Restore power to the boiler.

5.2.5 Vent High-Limit

This sensor has been installed to ensure the boiler is shut down safely if the heat 

exchanger or the venting system becomes blocked. 
The Vent Hi-Limit is located at the bottom of the heat exchanger just to the left of 

the vent outlet and above the condensate tray. For access, remove the vent stack 

and the condensate tray. 

5.2.6  Domestic Hot Water Flow Sensor

Section Reserved for the DC Series Boilers.

5.2.7  Domestic Hot Water Sensor

Section Reserved for the DC Series Boilers.

5.2.8  Outdoor Sensor

An Outdoor Sensor is supplied with each boiler. The sensor should be mounted 

on the north side of the building away from any direct sunlight. The sensor must 

also be kept away from any heat sources such as exhaust fan outlets, dryer 

outlets, mechanical room ventilation grills etc.
The Outdoor Sensor is a 12KΩ sensor with resistance values as listed in Table 

12. If the sensor is not connected to the boiler, the boiler will operate at the Boiler 

Supply Temperature set in the User Set Up menu and operate as a Set Point 

load.
