PER Series 3 Electric-Hydronic Boilers Installation Instructions

Checkout procedure

After filling and purging, start the boiler as follows:

Turn the thermostat to its lowest setting so that there is no call for
heat.

Set the limit control as recommended in the Installation Instructions.

Turn on the main electric switch to the boiler.

Set the thermostat above actual room temperature. Check for proper
sequencing of elements. Heat the entire system to about 200°F so that
dissolved air and gases in the system water will be emitted and vented.

Check limit control operation by lowering the
control settings as described in the
“Troubleshooting” section on page 7.

Restore the limit control settings to their
recommended values and set the thermostat to the
desired room temperature.

Fill in “Installation and service certificate” below.

If the boiler operates incorrectly or fails to start,
refer to “Troubleshooting” on page 7.
