WARNINGS & IMPORTANT INFORMATION

Using the dimensions shown on page 10, calculate

the required number and type of ue components that are needed to reach from the water heater to the ue

terminal.

When cutting components the outer ue pipe should be cut to the required length plus 37mm and the inner ue

pipe should be cut to the required length plus 47mm, this will ensure that the correct penetration is provided for joining of components.

When inner and outer pipes are re-assembled after cutting the inner pipe should extend 10mm beyond the end of the outer pipe. See Fig. 1.

Cutting ue components can create sharp edges, care must be taken to avoid injury, use a le to remove debris, burrs and sharp edges from cut ends.

Ends that are left unnished can damage the ue seals and result in the ue components no longer being air or weather tight.

The ONLY COMPONENTS that can be cut are as follows: FFPIPE1000, FFROOFCOWL and FFWALLTERM.

Ensure all ends are cut square (the use of a mitre box will ensure a clean square cut).

IMPORTANT

Drain Tube Cap

Fig. 12

NOTE

INSTALLATION METHODS

CONDENSATE DRAIN

The condensate trap and associated drain connection are integral with the appliance ue spigot. The condensate trap collects any condensate from the ue system, thereby preventing condensate from entering the water heater and causing damage.

A condensate drain tube kit is supplied with the terminals (FFWALLTERM and FFROOFCOWL) and will require connection to the condensate drain connection in ue systems where the total length exceeds 1.5 metres and condensate cannot be drained via the ue terminal. Usually, the condensate drain tube requires connection in ‘vertical ue’ and ‘combined vertical & horizontal ue’ systems and does not require connection in ‘direct horizontal’ and ‘extended horizontal’ ue systems.

If the condensate drain tube is not required to be connected it is important to keep the drain tube cap in place on the appliance ue spigot. It is ONLY to be removed if the condensate drain tube is connected (Fig. 12)

Appliances MUST NOT be operated with the drain tube cap removed and with no condensate drain tube connected.

As the condensate is a by-product of gas combustion it is mildly acidic. For this reason For this reason copper tube and ttings MUST NOT be used as it will corrode. Instead, Rinnai recommend plastic pipes and ttings such as Unplasticised Polyvinyl Chloride (UPVC) or Polyethylene (PE) which is commonly used for irrigation piping.
