Why will my Mosaic FSPTMV5004 burner not light?
- BBarbara BallAug 10, 2025
If the burner on your Mosaic Patio Heater won't light, first, make sure the gas cylinder valve is turned ON. If the pressure is low, turn the gas cylinder valve OFF and replace the gas cylinder. If these steps don't resolve the issue, it's possible that the hose and regulator are broken, or the valve is broken, requiring you to call customer service.
