Rated 5 out of 5 by from Excellent vent This is a great solution to venting where access is difficult - needed a vent in the attic of a 4 storey house where I couldn’t reach outside with a ladder. Cut a hole (see Erbauer core drills) from inside - 5 mins later had the vent fitted. Must follow the Manrose instructions - but if you need to trim then be careful - that’s the only bit of the instructions I found were not quite clear

Rated 5 out of 5 by from Excellent solution A well thought out and put together product. Very simple to install - follow the clear instructions and, after core drilling for the vent, fitting completed in less than 5 minutes. Completely eliminates the need for ladders or scaffold towers.

Would this be good enough to let sufficient air in for a gas boiler

Hello, This product would not be suitable for gas appliances as there is a backdraft shutter incorporated.
