Diesel Heater (pipe safety)

[HarrisonMelecchi]

Hello, I'm installing a diesel heater 5kw and I don't know how to protect my fiberglass hull. I made a small hole in the hull to insert the exhaust pipe out, so what is the best option to protect the hull against hot temperatures? I'm worried about the hot air pipe as well which comes from a hole in a wood wal and I know it can be dangerous. Any ideas? Thanks!!!

Check with the supplier because when I installed diesel heaters there was a balance flue option where the combustion air was drawn in around the outside of the flue so the outer metal stayed cool. Don't know if this is still available or available for your heater.

£30 for a noname cheap one.  £60 for a decent marine grade stainless steel one. £100 for a decent marine grade stainless steel one that has "WEBASTO" stamped on it.
