Steps for creating down and out flueing
1. Lubricate all inner pipe o-rings with the silicone grease provided.
2. Join the flue transition and condensate together ensuring the condensate arrow points
downwards. Even though the condensate is not actually connected in this flue arrangement,
the condensate component serves as a transition piece between the transition casting and the
ESPIPE900. The transition component must not be connected directly to the ESPIPE900 due
to heat of the flue gases.
3. Fit lengths of ESPIPE900 as required.
4. Create the floor penetration, ensure the hole edges are smooth. The minimum diameter is
80 mm to non-combustible surfaces such as brick, and 100 mm to combustible surfaces such
as plaster.
5. Pass the ESPIPE900 through the wall plate and through the floor penetration and secure wall
plate in place to seal the floor.
6. Prepare the horizontal section of the flue system under the floor by connecting ESPIPE900,
ESBEND and subsequent ESPIPE900 lengths as required. Allow for a 2° continuous fall from
the first section of horizontal pipe to the wall penetration to drain condensate.
7. Create the wall terminal, refer p.21.
8. Secure joints between flue components through the outer pipes with screws and secure the
entire flue system using the wall straps
supplied.
