Smoke detector beeps when furnace comes on

Q.  I have a vent about 6 feet from my furnace. Several feet from the vent I have a smoke detector. The smoke detector will give a short beep when the furnace first turns on after being idle for awhile. It is not a continual beep. Just a short one that stops and does not repeat.

My furnace is fairly new and is running properly. I had it checked. The detector is working properly and has a new battery. When the furnace is running I hold the smoke detector to the vent and there is no beep. Any ideas as to how I should proceed?

A.  Since the smoke detector is not hard-wired, and it is possible to move it, install it farther from the vent. Another option is to install a deflector on the vent, and see if it solves your problem.
