PIPING A HEATING - COOLING SYSTEM TO A WATER BOILER AND CHILLER
The chiller must be piped in parallel with the boiler. Figure below illustrates a method of piping a
The air control system and pressure control system must oper- ate with chiller only, or the boiler only, being valved to the piping system.
Separate control devices on the boiler and chiller may be used, or a single set of air and pressure controls on the common pip- ing may be preferred.
If the boiler is used to supply hot water to heating coils in air handling units, flow control valves or other devices must be installed to prevent gravity circulation of water in the coils dur- ing the cooling cycle.
IF REPLACEMENT PARTS ARE NEEDED
When parts are needed, refer to boiler model and serial num- ber shown on the boiler name/rating plate. Refer to publication number
Control identification and replacement should not be attempted by unskilled personnel. Only simple,
parts should be identified by and ordered from Slant/Fin. Relief/Safety valves must be ASME rated for the pressure and gross output of the boiler.
For replacement parts, heating contractors should contact their Slant/Fin boiler distributor.
