Water Heater Vent Cover

[Spanda]

We have a Truma combined space and water heater. The Owners Manual, and everything else we have read, says it is vital to take the cover off the outside vent when using gas to heat the water. Which we always do. But the Owners Manual doesn't say why it is so important. Can someone enlighten us ?

A picture would be useful

Sorry, a bit late, but here are the front and rear views of the cover.

The rear view shows one of the three lugs which line up with the cut-outs on your pic at the 12, 4 and 8 o'clock positions

Amazing
I wonder how many people ever had one of those
You'd think that it would be supplied with new vans ?

I've never even seen one before myself.

Cheers,

I googled and googled so must be discontinued and you'd think it would be supplied with new boilers ?
