THE UNIQUE EASY TO SITE OUTDOOR MODULE
A new innovation in central heating, the Grant Outdoor Module cuts cost dramatically as little or no building work is necessary. It comes complete with a built-in low level flue and can be either fixed against any suitable external wall, or installed freestanding allowing for the necessary clearances around the flue terminal. A conventional flue adapter is also available, allowing the flue to run vertically when siting conditions restrict low level applications.
