Which Webasto model does this installation refer to? I looked up the Air Top Evo 55 installation instructions specifically for marine use and that does not mention condensation drains. It also states that if the exhaust is over 2 metres it should not have a silencer fitted anyway!

If your exhaust runs downwards all the way (mine does), there's no need for a drain. It's all in stainless, so won't be a problem if there's a bit of moisture in there. It won't be there long after you start it, anyway!

These are the instructions to which ADI refers https://www.butlertechnik.com/downloads/Webasto_Install_Instructions_Marine_heating_systems.pdf
The instructions only relate to the specified Webasto products and include this safety warning:
If you want to install a Webasto® heater system yourself: The installation assumes that you have sufficient technical and craft knowledge and skill. Unskilled installation can endanger life! Before first use, the heating system must be checked by an authorized Webasto® Partner!This is both for your safety and for the safety of third persons.
It seems they only suggest a condensation drain if the length of the exhaust exceeds 2 metres.
I’ve attached a photo of my own installation (an Eberspacher) and there is certainly no drain fitted to the exhaust (the white pipe) and it’s never caused any problem.

Thanks Pally it's very helpful to see other people's installations, just need to source some appropriate fuel pipe now, I believe it has a safety code on it.

Tragic, but a timely reminder that diesel fumes can kill - quickly.

Thanks for posting that link Pally. I note from reading the full report that the source of co was the silencer, which wasn't inteneded for marine use. Highly relevant to this thread.
Due to the nature of my job (until I retired), I have been banging on about the dangers of carbon monoxide for years.

Yes thanks for posting definitely important to double check everything and make sure exhaust fittings are sealed, i have had a carbon monoxide alarm fitted for 11 years and replaced last year, it occasionally goes of on windy days when the canopy is back due to exhaust fumes being blown in, but a rare occurrence.

Just want to add I wont be using the silencer as the exhaust run will be about 1.5 meters.
