Blocking the Grille + Rain

Nevermind. Reading comprehension FTW.

 

Tideland,

I did last year when I first put mine in. Then I cut new pieces. I just cut the insulation in half, but not in half again. Use the 1/2 pieces folded. They should fit in snug enough in the upper grill. In the lower, I do half them again because the lower vents are smaller.

Hope this works.
Best of luck.

(BTW, you are using the grey/black foam pipe insulation, right?)

 

I've seen grill blocks where zip ties were used to secure the tubes. The trick is to cut two small holes to thread the tie through so that it doesn't loop over the tubes then squish them and let the outside air in.

 

This is what I did to secure the top foam pieces:

I threaded some long twisty-ties behind the vertical support piece of plastic that supports the metallic piece, then I rotated the twisty ties so they the two ends are vertical, one at the top part of the slit, one at the bottom part of the slit. then I stuck the foam between the top and bottom sections of the tie and stuffed it into the grill, then i twisted the tie, effectively trapping it between the ends of the twisty ties and the support behind the top grill.

 

I think I lost mine last spring at the hands of street urchins who realized they make great play swords! This time I'm going to zip tie them in place or electrify the chrome strip!
