CAST IRON PRESSURE TEST

NOTE: Before filling the sections with water temporarily set the flue collector(s) on top of the sections to locate the flue collector brackets, Figure

44.On 13 to 21 section models attach the top jacket splice panel bracket, Figure 45. Also mark the intermediate casting that the flue collectors rest on.

Install a valve in the top and bottom tapping of the left end section to vent any trapped air and allow boiler draining after pressure test completion. Connect a water pressure gage sized for the required test pressure to one of the end castings. Plug all the other tapped openings. Fill the cast iron sections with water leaving the top valve open until all of the air has been bled from the sections.
