Covering rigid foam insulation in furnace area

We put up some rigid foam insulation on an exterior wall behind our furnace and gas water heater. We know we have to cover the rigid foam because it's flammable and emits toxic fumes, but there isn't enough room down there to build a stud wall. We're thinking now that we should have used Wallmate with the built-in furring strips. So, my question is: can we just glue furring strips to the rigid foam and screw the drywall into them (without having to use Tapcon screws to go right through into the concrete, because we haven't had a lot of success with those)? It's an area that's only about eight feet wide by about seven feet tall -- the rest of the furnace room will be properly drywalled.

Rigid foam board is not structural. Inside the furnace door are the clearances for the other walls to combustibles.

I haven't used those nailing devices that use a 22 caliber blank to drive the nail, but I understand they'll put the specified nail right into a concrete slab. Maybe that would work for your furring.

If you can get any of these concrete nails you'll never go back to tapcons.

It shows a button head but there is also a countersunk head.

I get them at a hardware store that caters to contractors , won't find them at a box store.

Fastening to a concrete wall.

The process of choosing the best anchor to fasten to concrete might appear simple but the complex variables involved may quickly create complications. It is necessary to review the variables in order to simplify the process and make successful choices. The concrete anchors being considered are all mechanical type concrete fasteners. This means that the anchors derive their holding values from friction. A hole is drilled into the concrete and the concrete anchor used must be designed to go into a hole of equal size and then expand so that it becomes larger than the hole. This creates friction and this process ensures that the anchor does not come out of the hole. Check out the article on this site to help you choose the right fastener for your application.
