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. Conrm all electrical, water and gas supplies are turned off at the source and that vent is clear of obstructions.

3. Conrm that all manual shut-off gas valves between the boiler and gas source are closed.

4. If not already done, ush the system to remove sediment, ux, and traces of boiler additives.

5. Fill the boiler and hydronic system with water meeting the following requirements below (also see the NOTICE on the

next page):

• pH between 6.6 and 8.5

• Hardness less than 7 grains/gallon

• Chlorides less than 125 ppm

• Iron level less than 0.5 ppm

• Copper level less than 0.1 ppm

• Pressurize the system to at least 14.5 psi at the boiler

XI. Start-Up and Checkout

WARNING

Burn Hazard. The maximum operating pressure of this boiler is 80 psig (340 kPa). Never exceed the

maximum allowable working pressure on the heat exchanger ASME plate.

DANGER

Explosion Hazard. Do not use matches, candles, open ames 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 ammable vapors and liquids.

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 specied in ANSI Z21.13.

6. Bleed air from the heat exchanger and piping system.

7. Check all gas piping for leaks and purge piping sections that are lled with air. Refer to the National Fuel Gas

Code for additional information on testing and purging gas lines.

8. Conrm vent system is complete and free of obstruction before attempting to re boiler.

9. Inspect all wiring for loose, uninsulated or miswired connections.

10. If the boiler is to be converted to LP Gas (propane), convert as described in Conversion Kit instructions. If boiler is

operating at elevations above 2,000 Ft, see Appendix A of this manual for setup instructions.
