Adding wasp guard screen to furnace and water heater air inlets

[engrprof]

Another Covid-19 project: I installed 1/8" galvanized "hardware metal cloth" on our Thor Aria furnace air inlet and the water heater air inlet (shown directly above the furnace air inlet) (pic 1 but rotate 90 deg CW) to keep wasp nests out. The furnace panel had 2 metal pieces pop-riveted to hold the original 3/4" grid plastic guard in place. I drilled out the rivets and put the 1/8" screen in front of the original plastic guard (pic 2). However, I decided to add 2 more metal corner braces since the original setup just had the 2 corner pieces holding the plastic guard in place leaving the other 2 corners of the plastic guard with too much give (pic 3).

ALSO!! Put the screens on the Fridge vents!!! damn mud daubers and yellow jackets love the smell of propane..

Good suggestion Saddlesore: Our Thor Aria has a residential refrigerator (electric, so no vents), but I did add the screen to the propane Norcold fridge in our former Bounder MH. I also purchased a stainless steel screen to cover the furnace burner opening on the Thor Aria.

I use cheap dog flea collars in fridge vent, furnace and water heater. Replace each spring. seems to work.
