Extension Kit Installation - Rinnai EX08C Manuel D'installation Et D'utilisation

Extension Kit Installation (EX11C only)
If necessary, extension kits are available to extend the
exhaust line and air intake hose between the manifold
and the appliance.
(1) The maximum vent length is 13 feet (4 m) with 2
bends. The bent pipe attached to the appliance
does not count toward the max limit of 2 bends.
(2) For altitudes at or below 2000 feet (610 m), the
maximum vertical length is 8 feet (2.4 m). For
altitudes above 2000 feet (610 m), the maximum
vertical length is 5 feet (1.5 m).
(3) If the extension is longer than that shown in the
table below, the condensate may overflow the
condensation pan. Therefore, extensions
exceeding this length should drain to the outside
and sloped 3° downward.
8 feet (2.4 m) at or below 2000 feet (610 m)
5 feet (1.5 m) above 2000 feet (610 m)
(4) Do not allow any low points or sagging in the
exhaust line. Otherwise, condensate may block
the exhaust and affect combustion.
(5) Vent extensions installed in unconditioned air
space must be insulated with high temperature
insulation and must be accessible.
(6) Vent extensions must not be concealed per NFPA
54 and must be accessible allowing inspection and
repair. Decorative covers are available from
Rinnai.
These figures show the 3 possible ways that the
extension exhaust line and air intake hose may be
directed away from the appliance. All 3 views are from
behind the appliance. For your configuration,
position the air intake hose as shown.
