Heater unit replacement - does it need gasket to bulkhead?

[peteracs]

Hi All

Given it is a few years since I removed the heater unit from the bulkhead and now ready to reinstall, I need to understand if there is a gasket between the unit and the bullhead?

The parts book is unclear as no specific one is shown in the explosion picture and cannot see one in the list. Also I have two units and neither appear to have had one or at least there are no remains to be seen, but if I look at the bulkhead there is what I think are the remnants of a cork like gasket?

Given the position of the heater unit, it appears to be a natural water trap or is there a rubber seal which goes around the top of the opening in the bulkhead?

Hi Peter

I cannot remember for the Beta heater but on a Monte there is a foam gasket which I remade in closed cell foam to reduce leaks and remove a built in water trap.

I can't remember if there is a gasket to the bulk head but if my memory serves me, there is a rubber drain boot/pipe that drops any moisture back into the engine bay. So there probably isn't any need for a gasket.
There is a foam seal for the air flap but I think that is only to close the air flow, and not to prevent ingress of water as that is always going to happen on a rainy day with the fan on and flap open. Hence the drain pipe.

Thanks for the replies. The drain points on the area where the wiper motor sits etc will take the bulk of the ingress from the vents, however I was thinking of the small gap around the heater where it protrudes up into that area, albeit small/thin it looks to me like a built in water trap or easy access for water into the main cabin depending how sealed it is around the heater. I think I may use some rubber or foam to just make sure. On the flap you are correct there is foam which I have replaced, but that is mainly there to stop the flap rattling against the main body when closed I suspect and will having only a little bearing on water ingress into the heater given its inverted position.
