I recently had a new bryant gas furnace model 352aav installed. Now I do understand that it is 2 stage heat. Does that refer to the gas valve and the blower or just one of them. The airflow does not seem to be coming out of the vents enough for me. Is there a way to adjust the blower setting?

I would call back the installer. its his job to make the furnace right and you happy,, if you go to tinkering with it you could void your warranty

2 stage generally is just in reference to the gas valve. If you have one of those evil variable speed motors (yeah I'm looking at you KC) then it would obviously ramp up and down. But as wmproop mentioned, call the installer in and have him check the temperature rise.

As mentioned before the variable speed drive your furnace has is designed just to move enough air to get the job done. It does not work like conventional heat systems with the blowers that move the drapes around in front of the windows when running. If adjustments are necessary have a qualified service person make them. Damage to the unit might happen if the adjustments are incorrectly made.

The 352 has a 4 or 5 speed motor (depending on model/size), but only 3 speeds are wired to active terminals on the circuit board for use in low heat, high heat, and cooling. As suggested, have your installing contractor perform a temperature rise test in both heating stages to see if increased fan speed is in order. To do so yourself could result in problems with the unit down the road.

Yep no variable speed on that baby. But it still has the standard warnings.
