We have a 2010 29DS and I would like to purchase a Mud Dauber screen for the furnace.
I am thinking the JCJ M500 will work with the Zinger but the picture on http://mud-dauber.com/screen_m500.htmseems a little different than what I have although I seem to have the hydro flame 8500 series.
Check your furnace manual, I have a Suburban furnace and they do not recommend the mud dauber screens. They could restrict air flow. I have them on my furnace and haven't noticed any problems.
