Keep combustible material away
Place heaters on a stable surface with the clearances stated in the manual—commonly at least three feet from bedding, curtains, furniture and paper, but the exact product instructions control. Do not dry clothing on a heater or place it where people, pets or doors can knock it over.
Plug electric heaters directly into suitable outlets
High current can overheat extension cords, power strips and worn receptacles. Use a dedicated wall outlet when instructed. Stop if the plug, cord, faceplate or outlet becomes hot, discolored or loose. Never run a cord under rugs.
Combustion heaters can create carbon monoxide
Carbon monoxide is colorless and odorless. Headache, dizziness, weakness, nausea, chest pain and confusion can be warning signs. Move to fresh air and call emergency services if poisoning is suspected. Never rely on smell or an oxygen-depletion sensor to detect carbon monoxide.
Alarms are essential backups
Install and maintain smoke and carbon-monoxide alarms according to local requirements and manufacturer instructions. Test them and replace batteries or units on schedule. Alarms do not make outdoor-only equipment safe indoors.
Safety checklist
- Use only in approved locations.
- Maintain all stated clearances.
- Keep children and pets away.
- Do not leave operating heaters unattended or use while sleeping unless explicitly approved.
- Inspect cords, hoses and fuel connections.
- Maintain smoke and CO alarms.

If a carbon-monoxide alarm sounds or symptoms occur, go outside to fresh air immediately and call emergency services. Do not re-enter until authorities say it is safe.
