Furnace help (venting)

[thing]

Obviously this shouldn’t be happening. We’ve always had to clean up the intake due to frost build up. Never gave much thought to it. It was only done once or twice a season, some years never at all. However due the the extended cold snap we are in, we’re clearing it once a week. It’s dangerous, furnace quits, carbon monoxide is also a risk.

Is it as simple as changing angle of the intake (adding a 90 degree piece) or are there location issues?

The furnace was installed 6 years ago.
