2Prepare boiler

Model 500

1.Remove the top access cover from the unit (no tools required for removal).

2.Turn the adjustment screw on the gas valve clockwise until it stops. Then turn the adjustment screw counterclockwise four and three quarter (4 3/4) turns (see FIG. 2-3).

3.Use a combustion analyzer to verify CO2 is within the range of 9.6 – 10.5%. If not, adjust the screw counterclockwise incrementally to raise CO2 and clockwise to lower CO2 (FIG. 2-3).

4.After adjustment is complete, attach the propane conversion label (in the conversion kit bag) next to the boiler rating plate. Attach the LP caution label (in the conversion kit bag) to the left side of the unit in the lower left corner.

5.Replace the top access cover.

￿After converting to LP, check combustion WARNING per the Start-up procedure in Section 10 of this manual. Failure to check and verify combustion could result in severe personal injury, death, or substantial property

damage.
