EZ-Fit External Flues (Green System) for outdoor boilers

The Green Flue System can be installed with external Grant boilers when fitted with the relevant starter connectors and elbows. This allows for the extension of an outdoor module’s flue system to be redirected, either vertically or horizontally, to reduce nuisance pluming.

Features & benefits

All of Grant’s external oil boilers are supplied with a low-level flue as standard, however, the Green Flue System can either extend this horizontally or convert it to a high level/vertical system
Both the horizontal and vertical starter sections, like the other components in the Green Flue System, are manufactured from high grade stainless steel and are both also fully insulated and have ‘O’ ring seals and locking bands to ensure a rigid construction every time
Suitable for Grant Vortex & VortexBlue external boilers up to 70kW
Maximum vertical flue length = 8 metres
Maximum horizontal flue length = 4 metres
Supplied in modular form enabling most installations to be accommodated
Starter connections available for external boiler modules

Double skin extensions available in 150mm, 250mm, 450mm or 950mm fixed lengths and a 195-270mm adjustable length
