Component Assembly & Connection "On-Wall" Terminal ~ Eswtkit2 - Rinnai RHFE-308FTR Installation Manual

INSTALLATION METHODS
COMPONENT ASSEMBLY & CONNECTION "ON - WALL" TERMINAL ~ ESWTKIT2
To terminate an ON-Wall terminal a connecting pipe is required, this component is created from
sections of ESPIPE900 outer and inner pipes which is then attached to ESBEND and or ESPIPE900
flue components. Use the diagram & table below when creating the connecting pipe sections.

1. In accordance with the measurements provided above, measure
off and cut the outer pipe to required length A (minimum length is
70mm). Ensure that burrs and swarf are removed from all cut ends.
2. In accordance with the measurements provided above, measure
off and cut the inner pipe to required length A + B + C (minimum
length is 109mm).
all cut ends.
3. Lubricate the 'O-Ring' of the inner pipe of the preceding component,
this should be either an ESBEND or an ESPIPE900.
ONLY use non-acidic silicone sealant between the joints
of PVC flue pipe and any mating aluminium components
CAUTION
(such as those of ESROOFCOWL) to secure and seal these
joints against ingress of dust and water.
Silicone containing acetic acid, (characteristically having a
vinegar odour), as the curing agent or other acids may cause
corrosion of aluminium components and MUST NOT be
used.
Insert the cut section of inner pipe into the female socket of the
!
preceding component, ensuring that it is fully home. Then insert the cut
section of outer pipe into the female socket of the preceding component,
ensuring it is also fully home. There should ONLY be 27mm of inner
pipe section protruding when both inner and outer are fitted correctly.
When preparing an on wall terminal ensure a continuous
!
2° fall from the flue termination point back towards the
IMPORTANT
heater (condensate trap). This is especially important when
an ESPIPE900 is used to horizontally extend the terminal
location for the clearance considerations.
Additional supports may also be required.
4. Attach the flue terminal to the flue adapter using the three m4
screws supplied.
5. With the orientation arrow is pointing vertically upwards,
!
attach the above terminal assembly to the connecting pipes, ensuring
that the outer pipe hits the stopper dimples of the flue adapter. Then
secure the terminal in place with the two 8g screws supplied.
For the on wall terminal it is CRITICAL that the joints of PVC
outer pipes are sealed with an appropriate PVC solvent.
