Planning the Installation WARNING Fire or Explosion Hazard. Can cause property damage, severe injury, or death. Follow these warnings exactly: 1. Plan the installation as outlined below. 2. Plan for frequent maintenance as described in the Maintenance section. Review the following conditions that can apply to your specific installation and take the precautionary steps suggested. Frequent Cycling This control is designed for use on commercial cooking appliances that typically cycle 400 times a day, year round. Perform a monthly checkout. Water or Steam Cleaning If a control gets wet, replace it. If the appliance is likely to be cleaned with water or steam, protect (cover) the control and wiring from water or steam flow. Mount the control high enough above the floor so it does not get wet during normal cleaning procedures. High Humidity or Dripping Water Dripping water can cause the control to fail. Never install an appliance where water can drip on the control. In addition, high ambient humidity can cause the control to corrode and fail. If the appliance is in a humid atmosphere, make sure air circulation around the control is adequate to prevent condensation. Also, regularly check out the system. IMPORTANT Always install a splash cover to protect the control from water damage. Corrosive Chemicals Corrosive chemicals can attack the control, eventually causing a failure. If chemicals are used for routine cleaning, avoid contact with the control. Where chemicals are suspended in air, as in some industrial or agricultural applications, protect the control with an enclosure. Dust or Grease Accumulation Heavy accumulations of dust or grease can cause the control to malfunction. Where dust or grease can be a problem, provide covers for the control to limit contamination. ®U.S. Registered Trademark Copyright © 1999 Honeywell Inc. • All Rights Reserved 69-1174 S8701/S8702 DIRECT SPARK IGNITION CONTROLS S8701/S8702 DIRECT SPARK IGNITION CONTROLS Excessively high temperatures can damage the control. Make sure the maximum ambient temperature at the control does not exceed the rating of the control, see Table 2. If the appliance operates at very high temperatures, use insulation, shielding, and air circulation, as necessary, to protect the control. Proper insulation or shielding should be provided by the appliance manufacturer; verify proper air circulation is maintained when the appliance is installed. Table 2.

INSTALLATION When Installing this Product… 1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition. 2. Check the ratings given in the instructions and on the product to make sure it is suitable for your application. 3. The installer must be a trained, experienced service technician. 4. After installation is complete, check out system operation. WARNING Fire or Explosion Hazard. Can cause property damage, severe injury or death. If a new gas control is to be installed, turn off gas supply before starting installation. Be sure to conduct a gas leak test after the control is installed. CAUTION Electric Shock Hazard. Can cause personal injury or equipment damage. Disconnect power supply before wiring. IMPORTANT If this is a replacement application, follow the appliance manufacturer’s instructions, if available. The manufacturer usually provides wiring diagrams, start-up and checkout instructions and the service procedures for their system. If the manufacturer’s instructions are not available, this information may be used as a general guide. Mounting The S8701/S8702 Control Select a location within 6 ft (1.8m) of the burner that will permit a direct cable route to the spark igniter terminal. Ready access to the terminals is necessary for wiring and servicing. The S8701/S8702 control may be mounted in any position. Use No. 6-32 machine screws or No. 8 sheetmetal screws 1 inch long for fastening. Fasten securely. Do not exceed the ambient temperature rating given in Table 2. 13/16 (21) 2 (50) 1-1/8 (29) 2-13/16 (72) M16233 3-15/16 (100) 3-3/8 (86) 3-3/8 (86) 5/17 (7) 7/8 (23) 5-3/16 (130) 3/16 (4) Fig. 1.
