Johnson Controls G67BG-5 Intermittent Pilot Ignition Module With Spark Generation and Flame Supervision

Description

The Johnson Controls G67BG-5 is an intermittent pilot ignition module that manages pilot lighting and main gas valve operation in compatible gas-fired equipment. It generates an ignition spark during a heat demand and authorizes main burner operation after detecting the pilot flame.

Information About G67BG-5

The G67BG-5 is a non-self-checking version within the Johnson Controls G67 ignition control family. Its solid-state assembly combines spark generation, flame-sensing circuitry, and gas valve switching connections. The module operates with compatible pilot hardware, a thermostat circuit, and a redundant main gas valve arrangement. Johnson Controls restricts G67B applications to approved rooftop, excess-air, and power-vented gas-burning equipment.

Key Features:

• Intermittent pilot sequence: Activates pilot ignition during a thermostat call for heat.
• Flame confirmation: Prevents main gas valve energization until the sensing circuit proves the pilot flame.
• Spark interruption: Stops sparking after successful pilot ignition.
• Automatic reignition: Restarts pilot sparking if flame is lost while heat demand continues.
• Valve shutdown response: De-energizes the main valve within a maximum of 0.8 second following flame loss.
• Low-voltage operation: Uses a nominal 24 VAC control supply.
• Spark gap specification: Uses a nominal electrode gap of 0.1 inch.
• Solid-state circuitry: Integrates ignition sequencing and flame monitoring in one module.

The G67BG-5 delivers the reliability and precision required for pilot ignition sequencing and flame supervision in correctly matched gas-fired equipment.
