Direct Horizontal Flue; Extended Horizontal Flue - Rinnai HD210i Installation Manual

INSTALLATION METHODS

DIRECT HORIZONTAL FLUE

The Direct Horizontal Flue option (Fig. 7) is used for flueing directly through an external wall and FFPPWALLKIT
MUST be used for this purpose. Components included are: 90° starter bend, terminal pipe, white internal wall
seal and black external wall seal.
Installation Method
All horizontal flue is to be installed with a
3° fall towards the water heater.
IMPORTANT
Ensure there is enough space to install the
water heater, flue assembly and pipework.
Also ensure that the positioning of the flue
terminal complies with the requirements
of AS/NZS 5601 (see page 12).
1. Mount the water heater in an appropriate location.
2. Using the dimensions provided in Fig. 8, mark a
point 150mm along the appliance centreline from
the top of the water heater. This mark forms the
centre for the 140mm diameter wall penetration.
3. Make the 140mm wall penetration for the flue.
Ensuring that the flue spigot is covered to avoid
debris entering the appliance's flue connection.
4. Measure the required length for the horizontal
terminal to penetrate the wall and allow an extra
67mm protrusion from the inside wall surface as
shown in Fig. 9. See also the section "CUTTING
THE FLUE COMPONENTS" on page 4.
5. Fit the external wall seal to the terminal
pipe. Pass the male end of the terminal pipe
through penetration point and weatherproof the
penetration as required. Fit the internal wall seal
to the terminal pipe.
6. Connect the terminal pipe to starter bend (ensuring
components are pushed 'fully home'. Secure the
PVC joints of bend to the terminal pipe with the
three (3) self tapping screws supplied with the
component as shown in Fig. 10.
7. Connect condensate drain (go to "Condensate
Drain" on page 10 for connection details).

EXTENDED HORIZONTAL FLUE

The Extended Horizontal Flue option (Fig. 11) is used
when the water heater is mounted on an internal wall
and flueing needs to extend horizontally to exit an
external wall. Use ONLY FFPP components to extend
installations.
Refer to "Flue Length, Bends & Appliance Settings" on page 6 for flue run length limitations.
All horizontal flue is to be installed with a 3° fall towards the water heater.
IMPORTANT
1. Follow the installation method as described for the DIRECT HORIZONTAL FLUE above. Use FFPPPIPE1000
and FFPPBEND90 / FFPPBEND45 components to extend the installation horizontally as required. Note that
PVC joints MUST be secured with the three (3) self tapping screws supplied with the component as shown
in Fig. 10.
