The appliance concentric connection diameter is 80/125mm, to which the flue gas outlet
and air supply system can be fitted, with or without elbow pieces. The maximum
permissible pipe length is set out in Table 5.
We suggest you design a simple flue gas system and air supply system. For further
information about the available components of the flue gas and air supply system we
recommend you consult the Rinnai Flue system literature.
The Rinnai flue gas system is meant and designed solely for the use on Rinnai central
heating boilers adjusted to Nat gas or LPG. The maximum flue gas temperatures are
below 70°C (full load 80/60°C)
The operation can be influenced by changes or adjustments to the set up.
Possible warranty claims will not be honoured if incorrect changes result in non
compliance with the installation manual or local rules and regulations in force.
The flue gas systems described in this document are solely suited for Rinnai central
heating boilers of the Rinnai boiler range. For this purpose the CE Certificate has been
supplemented under the Gastec nr: 0063BR3405, 0063BQ3021, 0063AS3538 and
0063AU3110.
The flue gas system should be built up using only Rinnai flue products. Combinations with
other brands or systems are not permitted.
The terminal should be located where dispersal of combustion products is not impeded
and with due regard for the damage or discolouration that might occur to parts of the
building in the vicinity (see fig 5).
In certain weather conditions condensation may also accumulate on the outside of the
air inlet pipe. Such conditions must be considered and where necessary insulation of the
inlet pipe may be required.
In cold and/or humid weather water vapour may condense on leaving the flue terminal.
The effect of such ‘plumeing’ must be considered.
The terminal must not be located in a place where it is likely to cause a nuisance.
For protection of combustibles, refer to IS 813 section 9.10.1. where the terminal is less
than 2m (6.6ft) above a pavement or platform to which people have access (including) any
balcony or flat roof. The terminal must be protected by a guard of durable material.
A suitable guard is available from Rinnai.
Where a terminal is fitted below a window which is hinged at the top, and
where the hinge axis is horizontal, and the window opens outwards, the
terminal shall be 1m below the bottom of the window opening.
