Operation is shown in Table 4. TROUBLESHOOTING AND MAINTENANCE IMPORTANT: Due to the potential hazard of line voltage, only a trained, experienced service technician should perform the troubleshooting procedure. This control contains no field-serviceable parts. Do not attempt to take it apart. Replace entire control if operation is not as described. To completely troubleshoot an oil burner installation, check the burner and oil primary control for proper operation and condition. The indicator li

The primary controls fuel oil, senses flame, controls ignition spark and notifies a remote alarm circuit when in lockout. The R7184 can be used with both hydronic and forced air systems. When used with hydronic systems, line voltage switching Aquastat® Controllers normally provide for the starting and stopping of the combustion sequences. With forced air systems, both mechanical and electronic low voltage thermostats control the starting and stopping of the combustion process. Some hydronic and

Location 1. Mount on a 4 in. by 4 in. junction box, directly on the main burner or inside the appliance cabinet. In replacement applications, mount in the same location as the old control. See Fig. 1. Make sure the operating temperatures are within the ambient temperature range (see Specifications section). 2. Before mounting the control, make line voltage connections as shown in Fig. 2 through 7. Splice lines with solderless connectors. Do not exceed load ratings shown on the device label. 3. I

Bubbles indicate gas leak. 3. If leak is detected, tighten pipe connections. 4. Stand clear of main burner while lighting to prevent injury caused from hidden leaks which could cause flashback in the appliance vestibule. Light main burner. 5. With main burner in operation, paint pipe joints (including adapters) and gas control inlet and outlet with rich soap and water solution. 6. If another leak is detected, tighten adapter screws, joints, and pipe connections. 7. Replace part if leak can not b

Used with a thermopile in a self-powered system. See Table 1 for model specifications. TABLE 1—MODEL SPECIFICATIONS. Model Primary Aerated Type of Orifice Pilot Tip Type Includes Q314A No Insert Target Includes natural and LP gas orifices, 1/4 in. compression fitting, “F,” “K,” or “L” tip styles, “B” mounting bracket, and “A” mounting bracket adapter. Q327A Yes Spud Target Includes natural and LP gas orifices, 1/4 in. compression fitting, and “B” mounting bracket with screws. Installation WHEN I

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-connect to wire end at ignition module. 3. Strip other end and fasten under igniter-sensor mounting screw. 4. If necessary, use shield to protect lead from radiant heat of burner. 5. The pilot burner serves as the grounding area for the flame signal. Run lead from p

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

• S8600B,H; S86H only: The pilot lights, the spark stops and main burner lights, but the system locks out. If so, assure adequate flame current as follows: • Turn off furnace at circuit breaker or fuse box. • Clean the flame rod with emery cloth. • Make sure electrical connections are clean and tight. Replace damaged wire with moisture-resistant no. 18 wire rated for continuous duty up to 221° F [105° C]. • Check for cracked ceramic insulator, which can cause short to ground, and replace pilot b

Recheck ignition sequence as follows: • Reconnect main valve wire. • Set thermostat to call for heat. • Watch ignition sequence at burner. • If spark still does not stop after pilot lights, replace ignition module. • If main burner does not light or if main burner lights but system locks out, check module, ground wire, and gas control as described in control module instructions. 3 60-0653—8 Fig. 7—Example of unsatisfactory pilot flames.
