Nothing happens
Start with the manual-approved remote, thermostat, receiver, and power checks below. Lack of response does not identify a failed gas valve.
Quick answer
If you smell gas, leave immediately and call 911 and your gas supplier from outside. Otherwise, check the owner manual for remote batteries, operating mode, and power requirements. A silent unit, sparking pilot, and lit pilot without a burner need different diagnoses. Do not keep relighting a fireplace that fails to start.

Smell gas? Leave before troubleshooting
If you smell gas or suspect a leak, get everyone out immediately. Do not light the fireplace, operate switches, use a phone inside, or try to find or stop the leak. From a safe location outside, call 911 and your gas supplier. Do not return until emergency responders or the gas supplier say it is safe.
A repair booking is not an emergency response. See Peoples Gas emergency guidance.
What happens when you try to start it?
The useful clue is what the fireplace does, not simply that it is broken. Note the last symptom you observed; do not restart it just to reproduce a fault.
Clicking, but no pilot flame
Stop repeated attempts. Ignition, fuel supply, or control issues need model-specific diagnosis; clicking alone does not prove which component failed.
Pilot lights, but no main burner
Controls, connections, flame sensing, or a valve circuit may be involved. This is different from a pilot that goes out when the control is released.
It starts, then shuts down
Record the timing and any displayed error code. Leave the unit off for service if shutdown recurs, rather than repeatedly resetting it.
Checks you can make without opening the fireplace
Only proceed if there is no gas odor, suspected leak, or other safety warning. Let the fireplace cool and use the instructions for its exact make and model.
- Replace remote batteries as directed. Check a receiver battery pack only if the manual identifies it as homeowner-accessible.
- Confirm the selected operating mode and thermostat setting. Pairing and reset procedures differ by control system.
- Check whether a household power outage explains the failure. Battery backup, where fitted, must be used exactly as the manual describes.
- Note any known gas-service interruption or propane delivery issue and contact the supplier. Do not open a valve that may have been closed for a safety reason.
If these checks do not resolve the issue, arrange gas fireplace diagnosis and service. Do not remove fixed glass, move logs, clean gas orifices, bypass safety controls, or adjust gas pressure.
Standing pilot and electronic ignition are different
A standing-pilot system may use a thermocouple and thermopile in its safety and control circuits. Electronic ignition uses a different ignition and flame-sensing arrangement. Not every fireplace has the same sensors, power supply, or startup sequence.
A pilot that will not stay lit deserves a different check from a pilot that stays on while the burner remains off. The symptom guides testing; it does not confirm a replacement part. The manufacturer troubleshooting tables distinguish these cases and reserve internal diagnosis for qualified service personnel.
What to send when requesting service
Have the brand, model, and serial number available if you can read the rating label safely without dismantling the fireplace. Tell us whether it uses natural gas or propane, whether the pilot was visible, and whether you heard clicking or saw an error message.
Mention when it last worked and any recent outage, gas work, storm damage, or water entry. A photo of the accessible label or displayed error is more useful than a guessed part name. Request a diagnosis before approving replacement parts.
Manufacturer references
Heat & Glo owner resources cover model identification, controls, batteries, and manuals. Its ST-36TR-IPI / PIER-36TR-IPI manual illustrates electronic-ignition fault categories. These are examples, not instructions for every fireplace; use the manual for your installed model.
