## Questions & Answers

**Q: It states it is for indoors but is it CE-approved for that and could it be installed outside?**
A: Hello,

Yes, it is CE certified.
You can use it outdoors. A flue pipe would still be needed to avoid shut down by the flue safety sensor.

**Q: Is this a room sealed heater that can be installed in a bathroom complying with UK legislation?**
A: This one is not room sealed. It is an open flue type. It does meet UK legislation.
For a room sealed type that complies with UK legislation we recommend the TTulpe C-Meister 13
