Position the Q347 so that only the tips of the elec- trodes are immersed in the burner flame. The burner must ignite smoothly - usually this will be ac- complished with tip of electrodes (spark gap) spaced approximately l/4 in. [6.4 mm] from the surface of the burner.
Q354A FLAME SENSOR 1. Mate quick-connect terminals (l/4 in. [6.4 mmf)’ are provided on both the Q354 and S87D. Connect the SENSOR terminal on the 587 to the terminal on the Q354 as shown in Fig. 4. Use thermoplastic insulated wire with a minimum rating of 105 C [221 F] for the flame sensor leadwire; asbestos insulation is not acceptable.

FIG. a--NORMAL SYSTEM SEQUENCE OF OPERATION. SERVICE l Only persons trained and experienced in DSI systems should service this equipment. If a condition exists that causes the S87D electronic module to go into safety lockout, meter readings must be taken quickly after restart - within trial-for-ignition period.
GROUNDING CONNECTIONS A common ground is required for the burner, spark igniter-sensor mounting bracket and the GND terminal of the 587. If ground is poor or erratic, safety shutdown may occur occasionally even though operation is nor- mal at time of checkout.
t TROUBLESHOOTING . Start the system by setting the thermostat (tem- down to the next box. If the condition is not true or not perature controller) to call for heat.
