START-UP
Pre Start-up
Filling System (Heating Boilers)
Fill system with water. Purge all air from the system. Lower system pressure. Open valves for normal sys- tem operation, and fill system through feed pressure. Manually open air vent on the compression tank until water appears, then close vent.
Air Purge (Domestic Hot Water Heaters)
CAUTION: An air vent should be installed at the highest point in the system for proper operation. If water piping is located higher than the boiler, it should be relocated to the highest point in the installed system.
Purge all air from system before lighting heater. This can be normally accomplished by opening a down- stream valve.
Venting System Inspection
1.Check all vent pipe connections and flue pipe ma- terial.
WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.
2.Make sure vent terminations are installed per code and are clear of all debris or blockage.
