Do not impinge main burner flame on pilot burner/ igniter-sensor. 6. Do not expose pilot flame to falling scale, which could impair main burner ignition. 7. Do not expose pilot burner/igniter-sensor to main burner rollout while igniting or extinguishing. 8. Do not expose pilot flame to drafts that push or pull pilot flame away from the igniter-sensor. NOTE: The Q381A Pilot Burner/Igniter-Sensor is for horizontal mounting only. Mounting bracket must remain vertical. G. S. • Rev. 7-93 • ©Honeywell Inc. 1993 • Form Number 60-0653—8 CONNECT PILOT GAS TUBING CONNECT PILOT GAS TUBING Cut tubing to desired length and bend as necessary for routing to pilot burner/igniter-sensor. Do not make sharp bends or deform tubing. Do not bend tubing at control after compression nut has been tightened because this can result in gas leakage at connection. 2. Square off and remove burrs from end of tubing. 3. Push tubing into compression nut clearance hole until tubing bottoms. NOTE: When replacing a control, cut off old compression fitting and replace with new compression fitting provided with new pilot burner. Never use old compression fitting because it may not provide a gas-tight seal. See Fig. 3. Fig. 3—Always use new compression fitting. M3296 PILOT BURNER BODY ON BRACKET OF PILOT BURNER/IGNITER-SENSOR COMPRESSION FITTING BREAKS OFF AND CLINCHES TUBING AS NUT IS TIGHTENED TIGHTEN NUT ONE TURN BEYOND FINGER TIGHT TO GAS CONTROL 2. Connect one end of the ignition cable to stud terminal on igniter-sensor using 1/4 in. [6 mm] diameter snap-spring or cage-clips on cable ends. 3. Connect the other end of the ignition cable to the igniter terminal on ignition module. 4. Use ceramic or plastic standoff insulators as necessary to prevent cable from contacting metal surfaces. INSTALL BLEED GAS TUBE (optional) 1. Route bleed tube from bleed tap on gas control to the pilot burner/igniter-sensor. 2. Push clip into place. See Fig. 4. 3. Insert bleed gas tube until 3/8 in. [10 mm] to tubing is above pilot burner/igniter-sensor bracket. Tip of bleed gas tube must not extend into pilot flame. Fig. 4—Install bleed gas tube. BLEED TUBE CLIP 1/8 IN. STEEL TUBING THIS DIMENSION SHOULD BE MAXIMUM OF 3/8 INCH [9.5 mm] WHEN BLEED TUBE IS IN FINAL POSITION. M1261 4. While holding tubing all the way in, engage threads and turn until finger tight. 5. Using a wrench, turn compression nut one turn beyond finger tight. Do not overtighten. 6. Connect other end of tubing to gas control according to gas control manufacturer instructions. WIRE IGNITER-SENSOR The igniter-sensor must be mounted on the burner. Connect the control module ground wire to one of the igniter-sensor mounting screws to complete the system grounding. Connect ground wire as follows: 1. Use 221° F [105° C] minimum thermoplastic- insulated wire for the ground leadwire (asbestos insulation is not acceptable). 2. A male 1/4 in. [6 mm] quick-connect terminal is provided on Honeywell ignition modules. Fasten female quick-con...
