XI. Start-Up and Checkout
WARNING
Completely read, understand and follow all instructions in this manual before attempting
start-up.
NOTICE Safe lighting and other performance criteria were met with the gas train assembly provided on
the boiler when the boiler underwent the test specified in ANSI Z21.13.
Use the following procedure for initial start-up of the boiler:
1.
Verify that the venting, water piping, gas piping and electrical system are installed properly.
2.
Confirm all electrical, water and gas supplies are turned off at the source and that vent is clear of
obstructions.
3.
Confirm that all manual shut-off gas valves between the boiler and gas source are closed.
4.
If not already done, flush the system to remove sediment, flux, and traces of boiler additives.
5.
Fill the boiler and hydronic system with water meeting the following requirements below (also see the
note on the next page):

WARNING
Burn Hazard. The maximum operating pressure of this boiler is 30 psig (210 kPa) or
50 psig (340 kPa), depending on the model and safety relief valve option selected.
maximum allowable working pressure on the heat exchanger ASME plate.
6.
Bleed air from the heat exchanger using the manual air vent in the top left side of the heat
exchanger (Figure 11.1). To do this install a piece of ¼" ID clear tubing over the hose barb
and route the tubing to a location where water will not damage controls or nearby construction. Turn
vent counter clockwise and allow heat exchanger to vent until a steady stream of water is observed.
Close vent and remove hose.
7.
Check all gas piping for leaks and purge piping sections that are filled with air. Refer to the National
Fuel Gas Code for additional information on testing and purging gas lines.
DANGER
Explosion Hazard. Do not use matches, candles, open flames or other ignition source to
check for leaks.
Make sure that the area around the boiler is clear and free from combustible materials, gasoline and other
flammable vapors and liquids.
8. Confirm vent system is complete and free of obstructions before attempting to fire boiler.
9. Inspect all wiring for loose, uninsulated or miswired connections.
10. If the boiler is to be converted to propane, convert as described in conversion kit instructions. If boiler is
operating at elevations above 2000ft, see Appendix A of this manual for setup instructions.
11. Start the boiler using the lighting instructions on page 103. With the boiler powered up, and with no call for
heat, the display should look like Figure 11.2a. Once a call for heat is present, it will look like Figure 11.2b.
