Running out of propane can leave a home cold and a furnace unresponsive. This article explains safe, step-by-step procedures to restart a propane furnace after an outage, how to purge air from lines, troubleshooting tips, and when to call a professional. It emphasizes safety, common causes, and preventive maintenance to minimize future interruptions.
| Topic | Quick Takeaway |
|---|---|
| Initial Safety Checks | Always shut off power and gas, ventilate area, and check for leaks. |
| Refill And Valve Steps | Confirm tank refill, slowly open the tank valve, then open the furnace service valve. |
| Bleeding Air From Lines | Many systems bleed automatically; some require manual purging or pilot relight. |
| Ignition Types | Electronic ignition typically resets automatically; standing pilot may require relighting. |
| Troubleshooting | Check filters, error codes, regulators, and pressure; call a pro if unsure. |
Always prioritize safety: ventilate, check for leaks, shut off power when needed, and evacuate if a strong odor exists. Confirm the tank is refilled and open valves slowly. Allow time for air to purge and the regulator to stabilize. Understand whether the furnace uses a standing pilot or electronic ignition and follow the appropriate relight or reset steps. When in doubt, contact a licensed technician or the propane supplier.
For further resources, consult the furnace owner’s manual, the local propane supplier, and reputable HVAC associations for guidance on maintenance and certified contractors.
