Determine that the water pump(s) are operating
properly.
Test low water cutoffs, automatic feed controls, pressure,
and temperature limit controls, and relief valves to
determine they are in operating condition.
Preliminary Inspections
System Start-Up and Adjustment must be carried out
by qualifi ed installers.
The following checks must be made at Start-Up and
whenever maintenance or service is performed:

and make sure all the air in the hydronic
system, including boiler, has been vented.
2. Verify there are no water leaks in the boiler or
system.

on the boiler data plate. Do Not exceed this
pressure and Do Not plug the system pressure
relief valve.
3. Verify the electrical system is properly con-
