Pool heater exhaust pipe insulation against wood

[Boatmanea]

I have a pool heater with a 6" vent pipe that is routed through a wood picket fence. I am concerned that the heat from the pipe will damage the wood and potentially be a fire hazard. Is there a recommended insulation material that I can use around the hold in the fence that the pipe passes through that insulates the wood? I'm thinking of something like a pool noodle that I can slip over the edges of the fence boards, but made of a heat resistant ceramic/silicone material. Any suggestions?

Insulation is not necessarily a great idea.

It's not code, but if you have vented with standard double wall gas vent, it will probably be fine. I'd probably risk it IF the wood fence isn't near anything else combustible. If it is, you probably need to go with code clearance gaps. Your heater manual probably has those dimensions. You might have to get a piece of galvanized sheet metal, with an appropriately sized hole, to fill the gap in the fence.

If you want to be super safe, splice in a section of stainless triple wall wood stove vent.
