External vertical and high-level flue systems are optional accessories which have been designed to enable the extension of Grant external module flue which comes as standard on all outdoor modules. The flue system is manufactured from high grade stainless steel.
All of the Grant external modules come with a low-level flue as standard. The green flue system allows for the extension of this flue to provide against pluming nuisance. The flue is available in modular form which allows it to cater for most installations. The starter elbow will convert and of Grant external modules to a vertical or high-level conventional flue operation. The starter straight connector will allow any of the Grant modules to discharge at a low level and can be extended horizontally. The stainless-steel flue components are fully insulated the accompanying ‘O’ rings seals and locking bands provide a rigid construction.
