Low Temperature Piping
Figure 6A
(See Notes and Adjustment Procedures)
Adjustment Procedure
To Maintain Inlet Temperature
Above Dew Point
T1-Temp-Min=110°F For Atmospheric
T1-Temp-Min=125°F 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.

(See Notes)
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.
