Attach manometer to the manifold side pressure test fitting and verify manifold pressure reads 3.5 inches water column (0.87 kPa) for natural gas, and 10.0 inches water column (2.49 kPa) for propane gas. c. Refer to Figure 60 and remove the pilot hood assembly to access the hexed pilot orifice. Remove and replace the orifice with the one provided with the kit. Step 5. Millivolt Appliances - Honeywell Systems a.Convert the gas valve as follows (seeFigure 61): Remove the plastic protecting cap. Remove the gas type setting screw by turning it counterclockwise. Obtain the replacement gas type setting screw from the kit and screw it into place (red for propane and blue for natural gas). Tighten the gas type setting screw by turning it clockwise. Replace the plastic protecting cap.

Convert the pilot orifice as follows (refer to Figures 62, 63 and 64): Note - Use extra care not to engage the orifice strip with the 7/16" open end wrench (contacting the orifice strip could cause strip distortion rendering the pilot inoperative). Also avoid wrench contact to any of the other pilot parts. Use a 7/16" open end wrench and turn the pilot hex fitting counter-clockwise 1/4 turn. (refer toFigure 62 ). Note -The orifice strip tab may be randomly located on any side of the hex fitting. d. Push the orifice strip tab all the way against the hex fitting to align the appropriate gas type orifice (refer to Figures 63 and 64). The type of gas for which the pilot is set, is, the gas type shown on the tab. e. Retighten, clockwise, the pilot hex fitting until the pilot hood aligns with the thermocouple and thermopile as indicated by the arrows shown in Figure 62. Step 6. Electronic Appliances - Honeywell Systems See Figure 65 and the instructions provided with the kit. Remove the slotted cap screw, o- ring, pressure-regulating adjusting screw and spring. Retain all parts for possible later use. Install new components from the kit. Black cap and red spring for propane gas units. Silver cap and stainless steel spring for natural gas units. Before installing the cap, attach manometer to the manifold side pressure test fitting and adjust screw until pressure reads 3.5 inches water column (0.87 kPa) for natural gas, and 10.0 inches water column (2.49 kPa) for propane gas. See Figure 66 and replace the pilot orifice as follows: Remove the ignitor assembly retainer clip, and carefully remove the ignitor assembly. Exercise extreme care to prevent damage to or breakage of the ignitor assembly.
