Use the following procedure for initial start-up of the boiler:
1) If not already done, fl ush the system to remove sediment, fl ux, 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 below (also see the note on the next
page):
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 fi lled 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 fi re boiler. Make sure that the silicone cure
time called for in the vent assembly instructions has passed before fi ring boiler.
5) Inspect all line voltage wiring for loose or uninsulated connections.
