Installation Instructions

Site Requirements

1. Flue & Chimney Requirements

1.1  The chimney or flue system must comply with the rules in 

force, and must be a minimum of 127mm in diameter. (5").

1.2  The minimum flue height for the appliance must be 3 metres 

(10ft). Any horizontal flue run from the rear outlet must not 

exceed 100mm from the back of the appliance.

1.3  The chimney or flue must be free from any obstruction. Any 

damper plates must be removed or secured in the fully open 

position, and no restrictor plates fitted.

1.4  The chimney must be swept prior to the installation, but it 

need not be swept if  it can be seen the chimney is clean 

and unobstructed throughout its entire length.

1.5  A5" (127mm) liner must be used if fitting the appliance into 

an existing brick built chimney.  

Larger lined flues can work, but in some instances could 

cause cold start flue problems resulting in nuisance 

shutdown. Lined flues above 7" (175mm) are not 

recommended.

1.6  Due to recent changes to European chimney standards, 

new flues and chimneys are described by their temperature, 

pressure and resistance to corrosion, condensation and fire. 

To assist in identifying the correct flue system, the minimum 

flue specification is shown in the Technical Specification. 

Existing chimneys are not covered by this system.
