CUTTING ~ ESDFK, ESPIPE900 & ESROOFCOWL
IMPORTANT
STOP! When terminating a flue run and installing the wall terminal, follow the instructions
under "Component Assembly & Connection ~ ESROOFCOWL" on page 23 for pipe cutting
procedures.
CAUTION
Cutting is not required for the purposes of joining ESDFK, ESPIPE900 & ESROOFCOWL together
Cutting of the last component in the flue assembly (the component furthest away from the heater)
may be required to achieve the required flue system length. Cutting is also required at a wall
penetration. Cutting for both purposes is described below:
Cutting components to achieve a desired length:
1. Measure and mark off the outer pipe at the desired length ( AA ).
CAUTION
The minimum length ( ZZ ) of ESDFK when measured from the back plate of the casting MUST
NOT be less than 300mm when joining to other components.
2. Cut the outer pipe to the required length. Take care
NOT
to cut the inner pipe.
3. From the ‘new’ end of the outer pipe (cut in Step 2.), measure and mark off an additional 12mm on the
inner pipe (
BB
). Cut the inner pipe at this mark. Take care to keep the cut parallel with that of the outer pipe.
4. Ensure all burrs and swarf are removed from all cut ends.
Cutting components at a wall penetration:
1. Measure and mark off the outer pipe at a point flush with the surface of the wall penetrated (
CC
) PLUS
an additional 50mm (
DD
)
CAUTION
The minimum length ( ZZ ) of ESDFK when measured from the back plate of the casting MUST
NOT be less than 300mm when joining to other components.
2. Cut the outer pipe to the required length. Take care NOT to cut the inner pipe.
3. From the ‘new’ end of the outer pipe (cut in Step 2.), measure and mark off an additional 12mm on the
inner pipe ( BB ). Cut the inner pipe at this mark. Take care to keep the cut parallel with that of the outer pipe.
4. Ensure all burrs and swarf are removed from all cut ends.
COMPONENT ASSEMBLY & CONNECTION ~ ESPIPE900
Lubricate O-Rings with the supplied O-ring grease, then fit the female aluminium inner pipe end over the male
inner pipe ends of an adjoining component.
CAUTION
Both the inner and outer pipes of all internal horizontal components MUST be secured with
rivets or screws. The joints of PVC outer pipes that are exposed to an outside environment MUST
be sealed with an appropriate PVC solvent.
