flame sensing

technology

• Custom pre-purge and inter-purge timings*

• Single or three trials for ignition

• Mounts on standard 4-in. junction box

•System diagnostic LED

• Flame current test points

• Local or remote flame sensing

• Automatic reset option**

APPLICATIONS

• Commercial cooking

•Water heaters

• Other applications requiring intermittent pilot

DESCRIPTION

The 35-63 is a 24 VAC intermittent pilot (spark-to-pilot) ignition

control. The control uses a microprocessor circuit to provide

precise, repeatable timing and operating sequences. On-board

diagnostics with LED output makes troubleshooting easy and

ensures safe and efficient operation.

SEQUENCE OF OPERATION / FLAME RECOVERY / SAFETY LOCKOUT Lockout Recovery Recovery from lockout requires a manual reset by either resetting the thermostat, or removing 24 VAC for a period of 5 seconds. On models with automatic reset, if the thermostat is still calling for heat after one hour, then the control will automatically reset and attempt to ignite the burner.

MOUNTING AND WIRING Wiring Diagrams - 35-63 The Series 35-63 is not position-sensitive and can be mounted vertically or horizontally. The case may be mounted on any surface with #6 sheet metal screws. The control also supports direct mounting to a standard NEC 4-in. junction box. CAUTION GAS VALVE All wiring must be performed in accordance with both local and national electrical codes. MAIN GAS VALVE CAUTION Label all wires prior to disconnection when servicing controls.

TROUBLESHOOTING Proper Electrode Location Proper location of electrode assembly is important for optimum system performance. The electrode assembly should be located so that the tips are inside the flame envelope and about 1/2-inch (1.2 cm) above the base of the flame as shown: Troubleshooting Guide Symptom Recommended Actions 1. Control does not start A. Miswired B. 24 VAC transformer fault C. Fuse circuit breaker fault D. Faulty control, check LED for fault codes 2. Thermostat on - no spark A.
