Finned copper tube gas boilers & water heaters – Boiler Manual12Figure 6 Low Temperature Piping(See Notes and Adjustment Procedures)Figure 6A Multiple Boiler Piping(See Notes)H-15 Rev 5NOTES:1. Boiler circuit piping must be large enough to handle maximum flow through unit.2. Boiler pump sized to boiler design flow 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 flow through all units.Notice: These drawings show suggested piping configuration and valving.Check with local codes and ordinances for specific requirements.Adjustment ProcedureTo Maintain Inlet TemperatureAbove Dew PointT1-Temp-Min=110°F For AtmosphericT1-Temp-Min=125°F Sealed Combusion1. Turn heater on and open valves A & B.2. After steady-state operation, if T1 is lessthan Temp-Min slowly close valve B untilT1 climbs to desired operating temperatureabove Temp-Min.3. If T1 is greater than desired operatingtemperature, slowly close valve A to adjust tolower desired temperature above Temp-Min.4. Check after system operating temperaturehas stabilized. Make final adjustments.5. Follow same adjustment procedure forsealed combustion.H-3 Rev 6NOTES:1. Boiler circuit piping must besized large enough to handlemaximum flow through unit.2.
