xI Start-up and Checkout
Use the following procedure for initial start-up of the boiler:
1) If not already done, flush the system to remove sediment, flux, and traces of boiler additives. This should
be done with the boiler isolated from the system.
2) Fill the boiler and hydronic system with water meeting the following requirements:
pH between 6.5 and 8.5
Total Solids less than 2500 PPM
Hardness less than 120 PPM (7 Grains/Gallon)
Pressurize the system to at least 12 psi at the boiler
3) Check all new piping for leaks and purge piping sections that are filled with air. See the National Fuel Gas
Code for additional information on testing and purging gas lines.
4) Vent system must be complete and free of obstructions before attempting to fire boiler. Make sure that the
silicone cure time called for in the vent assembly instructions has passed before firing boiler.
5) Inspect all line voltage wiring for loose or uninsulated connections.
6) Remove the dust cap from the condensate trap (Fig 6.11). Add water to the trap until water runs out the
condensate drain. Reinstall the dust cap.
