Installation Guide

11. System start up.

With the boiler power shut off, activate all of the thermostats. All of the

zone circulators should turn on. There may be an initial gurgling noise, but as any

remaining air is vented out the air eliminator, the system should be quiet in a

couple minutes. Check for leaks. Turn boiler power on. The boiler circulator

should turn on and the boiler fire up. Observe temperature and pressure gauges.

The water temperature entering the zones will need to adjusted as designed,

never exceed 140 F for in-floor zones and 180F for radiators. The system

pressure should not increase more then 1 psi.

The water temperature is adjusted on condensing boilers via the boiler

electronic interface. See the boiler manufacturer manual for specific instructions.

With non-condensing boilers the water temperature is adjusted on the

panel with the 3-way mixing valve. Turning the knob in reduces the temperature

and turning the knob out increases the outlet temperature. Make adjustments

slowly to let the system adjust.

Congratulations!

Your system is now complete and ready for may years of

trouble-free operation.
