Caution
It is imperative that the flue should be properly sealed where it passes through the roof, this can best be
achieved by using the approved method of roof flashing plate and cravat.
The flue outlet on all GUH heaters can be in either vertical or horizontal (top or rear) configuration.
Note
It should be noted that claims made under warranty and attributed to the ingress of water may not be
considered especially if an approved method of sealing has not been used, or if the design of the flue has
not made provision for possible condensation problems.
Where a horizontal outlet is used, the manufacturer strongly recommends that a flue venter of an
approved type is fitted to aid the evacuation of the combustion products.
It is also recommended that BS5854: 1980 and BS5440: parts 1 and 2 are used as a consultative
document when considering flue requirements.
