## Questions & Answers

**Q: The description says white surface mount. i need to know if this product which is black a surface mount?**
A: Yes it is a surface mount but the wires must go thru the wall behind it.  I had to replace mine as it stops being effictive after 5 years as will the new one. It was a perfect fit replacement!

**Q: Can I mount this rotated 90 degrees?**
A: Yes you can mount in a rotated position. The mount allows the monitor to slide into place so you need room for the to work. Additionally, these require at 60 month replacement. The one I purchased lasted 12 months before it was beeping. Don't expect to get 60 months out of your purchase.

**Q: Can this unit replace model 25-741 ?**
A: It might plug in with the same connector, but model 25-741 is also for carbon monoxide and the 20-441 only detects propane.  I would not recommend making this substitution unless you have a separate carbon monoxide detector.

**Q: Gas detector for Home**
A: NO
