WATER PIPING AND CONTROLS

6.Install this boiler so that the gas ignition system components are protected from water (dripping, spraying, etc.) during appliance operation and service (circulator replacement, condensate trap, control replacements, etc.).

7.If this boiler and distribution system is used in conjunction with a refrigeration system, pipe the chilled medium in parallel with the boiler and install the proper valve to prevent the chilled medium from entering the boiler. A drawing illustrating this hook- up is provided in Figure 3.2.

8.When the boiler is connected to heating coils located in air handling units where they may be exposed to refrigerated air circulation, install flow control valves or other automatic means to prevent gravity circulation of the boiler water during the cooling cycle.

9.If this boiler is installed above radiation level, provide a low water cutoff device, either as a part of the boiler or at the time of boiler installation.
