Ef26 Condensate Neutraliser Tank And Drain - Rinnai INFINITY A-Series Installation Manual

EF26 condensate neutraliser tank and drain

The Rinnai INFINITY EF26 water heater generates condensate continuously at a rate of up
to 5 litres per hour as a by-product of a highly efficient gas burner. This condensate has been
neutralised by having an inbuilt condensate neutraliser kit.
Important considerations for the neutraliser drain pipe
The content of AS/NZS 3500 ' Temperature / Pressure Relief and Expansion Control Valve Drain
Lines' has been used as a guide in preparing the information below.

A. Water heater drain outlet connection, R½"
(15 mm) BSP male. Condensate / neutraliser
drain outlet connection, ½" (15 mm) BSP male
nylon.
N.B: The black plastic shipping cap MUST BE
removed from the condensate / neutraliser
drain outlet prior to water heater operation.
B. PE R½" BSP (15 mm) female to barbed
irrigation system connector (13-19 mm) or
equivalent plastic fitting
C. Drain pipe and fittings to match B.
D. Continuous fall of at least 2° from water
heater to discharge point. Lengths and bends in
accordance with the table below.
Lengths and changes of direction
Max. length (m)
Max. changes of direction greater
than 45°
E. Suitable points of discharge are deemed to
be drains, sewers or pits. DO NOT discharge
onto electrical connections, earth stakes,
copper pipes, concrete paths or into a pond.
Non-PE plastics will fail over time due to contact with the acidic condensate. Damage caused by installation of non-PE plastics will not

Installation
The drain line MUST NOT discharge onto
electrical connections, earth stakes, copper
pipes, concrete paths or into a pond.
The point of discharge from each drain
line shall be located so that the release of
condensate / neutraliser does not cause a
nuisance, is readily discernible and incurs no
risk of damage to the building.
There shall be no tap, valve or other restrictions
in any line.
Each line shall fall continuously from the valve
to the approved point of discharge.
Drain lines shall not discharge into a storage
water heater safe tray.
The end of the condensate line shall be:
• Not lower than 200 mm or higher than
300 mm above an unpaved surface; or
• Not lower than 75 mm, or higher than
300 mm above a gravel pit not less than
100 mm in diameter in a paved surface.
• Where discharging over a tundish or gully
trap, drain lines shall have an air gap of a
size at least twice the diameter of the drain
line.
