Description
The Johnson Controls G670AW-1 intermittent pilot ignition control automatically ignites a pilot burner and energizes the main burner gas valve when a thermostat calls for heat. Designed for gas-fired heating equipment, it replaces G67AG and G67BG ignition controls and supports applications with firing rates up to 400,000 Btu/hr.
It operates from a 24 VAC, 50/60 Hz NEC Class 2 power source and draws 0.15 A during operation. The control supports gas valves up to 2 A maximum, functions within ambient temperatures from -40°F to 150°F, and utilizes a 0.100-inch spark gap for ignition performance.
Frequently Asked Questions
What does the G670AW-1 do?
It automatically lights a pilot burner and energizes the main gas valve on a call for heat, then de-energizes both when satisfied.
What is the maximum firing rate?
It can be used with equipment up to 117 kW (400,000 Btu/hr). Higher rates require advance written engineering approval.
What gas valve system is required?
All applications must use a redundant gas valve system with the main valve seats arranged in series.
