NOTES:

1. Boiler circuit piping must be large enough to handle

maximum fl ow through unit.

2. Boiler pump sized to boiler design fl ow requirements.
3. All boilers furnished with factory mounted outlet water

temperature gauge.

4. Boiler pump purging required. Use terminals supplied.
5. Secondary loop pipe diameter must be sized large enough to

handle maximum fl ow through all units.

Notice: These drawings show suggested piping confi guration and valving.
Check with local codes and ordinances for specifi c requirements.

Adjustment Procedure

To Maintain Inlet Temperature

Above Dew Point

T1-Temp-Min=110° For Atmospheric

T1-Temp-Min=125° Sealed Combusion

1. Turn heater on and open valves A & B.
2. After steady-state operation, if T1 is less

than Temp-Min slowly close valve B until
T1 climbs to desired operating temperature
above Temp-Min.

3. If T1 is greater than desired operating

temperature, slowly close valve A to adjust to
lower desired temperature above Temp-Min.

4. Check after system operating temperature

has stabilized. Make fi nal adjustments.

5. Follow same adjustment procedure for

sealed combustion.
