FLUE COMPONENT ASSEMBLY
CREATING AN “IN-WALL” FLUE INSTALLATION ~ ESFKIT03 & ESKITIW
The In-Wall vertical Co-Axial flue system is installed within a stud wall with cavity depth a minimum of 90mm and
is run vertically upwards through the stud wall cavity and includes a condensate trap.
When considering the location of the heater due care must be taken to ensure that the flue path in the internal wall
and roof space are free of obstructions such as studs, noggins, joists, braces, and electricals etc. A top plate
bracket is provided to seal the flue penetration through the top plate.
1. Use the lower end points (iv and vi) of the flue spigot arc from “WALL PENETRATIONS” on page 6 to
determine the shaded spigot area ix.
Point H is the centre point of the transition casting and the point from which all measurements are taken. The
starting point H may be placed anywhere within the shaded spigot area ix.
Using the dimensions shown above create a 300mm high by 200mm wide opening. The bottom left corner of
this opening is 75mm to the left of starting point H and 50mm below starting point H.
2. Remove the screw from the front of the transition casting (retain and do not discard) and slide the wall
spacer plate over the transition casting so that the folded tab is facing both down and to the rear.
Using the screw removed from the front of the transition casting attach the mounting strip across the front of
the transition casting.
Lubricate the O-Ring of the condensate trap and attach this to the transition assembly ensuring that the
drain tube is facing to the front.
3. Install the above assembly in to the wall cavity observing the measurements shown to ensure the
correct fitting of heater and other components. Secure in place with appropriate fixings.
