Safe, effective sound dampening options for a noisy gas furnace?

We have our gas furnace next to our living room downstairs. It's getting colder and the furnace fires up every 15-30 minutes, heats up some air for another few minutes and then shuts off.
During the air-heating step, the furnace is loud. Very loud. To the extent that relaxing to a movie or just chilling out on the couch has now become a bit of problem.
I'd like to figure out what I can do to safely dampen sound from or around the area where the furnace is installed.
It should be effective, but safety is an equal criterium here: The furnace needs to draw fresh air and exhaust carbon monoxide the way it does now (or the way I assume it does), and I also don't want any dampening material to overheat and catch fire.
Is this something where I would have to spend thousands of dollars to hire an HVAC specialist, and so I will not be able to do this, or are there dampening materials that work for this application, which are reasonably priced and are safe to install?
