Gas Heating Intermittent Pilot Ignition Module Lockout Universal For: 780-845

Gas Heating Intermittent Pilot Ignition Module Lockout Universal For: 780-845

Safety first: Installation must be performed by a qualified gas-service technician. Isolate electrical power and fuel before service, never bypass flame-safety controls, and complete required leak, ignition, and combustion checks before returning the equipment to service.

Restore safe pilot ignition with this ERP replacement intermittent-pilot ignition module with flame monitoring and safety lockout for compatible gas-heating systems. The module sparks the pilot, proves flame, and protects the system: per the manufacturer documentation it runs a 90-second ignition trial, waits six minutes between retries, and locks out for one hour after three unsuccessful trials. Do not substitute a non-lockout module where the original lockout design is installed. Match the exact installed control, gas application, and wiring requirements before ordering.

Installation Instructions

1. Shut off the gas supply and isolate electrical power to the equipment.
2. Confirm the control type, gas application, sensing arrangement, and wiring diagram.
3. Disconnect the gas, pilot, and control wiring from the old module.
4. Install the new module, reconnect the pilot and wiring, and leak-test every connection.
5. Complete required ignition and combustion checks before returning the equipment to service.

Ignition, flame-proving, and gas-control faults require professional diagnosis; replacing this component will not correct every no-heat condition.
