2.INSTALLATION OF BLEED PIPING (V88 Gas Train only) – Using ¼” OD aluminum tubing, install a bleed line on both diaphragm gas valves, connect together, and, on USA boilers, run tubing to bleed line protruding from inside base, see Fig. 30. On boilers installed in

Canada, run bleed line to outdoors.

3.INSTALLATION AND WIRING OF S8610M IGNITION CONTROL MODULE – Using two #10-32 x 2” MS, and nuts, install the S8610M module bracket on the manifold just to the right of the main burner with pilot, see Fig. 28. Using two #6 x ¾” SMS, install the S8610M module on the bracket. Connect the two wires from the Q3481B pilot to the S8610M module as shown on Fig. 42, 43 or 44.

a. Ground Wire (200ºC) to “BNR GND” terminal b. Ignition Sensor Wire to “Spark” terminal

Secure these wires to Pilot Piping with Wire Tie to provide strain relief.

Using wiring harness furnished, connect leads with push-on terminals on S8610M module as shown in Fig. 42, 43 or 44. Run harness outside of jacket on underside of manifold and secure in this position with Wire Ties furnished. Connect the six wires in the harness to the specified controls as shown in Fig. 42, 43 or 44.

4.COMPLETION OF WIRING – Connect power supply fused disconnect switch, service switch, primary side of transformer, gas valves and remaining controls – see Fig. 42, 43 or 44 for wire type and connections to be made. All wiring must be adequately supported and strain relief provided. All wiring including ground connections must comply with the requirements of the authority having jurisdiction and, in the absence of such, to the National Electrical Code, ANSI NFPA

No. 70-2005, or the Canadian Electrical Code, C22.1, whichever is applicable.
