7. CONDENSATE REMOVAL
All SP6 models have a condensate drain outlet. A fitting and clamp are provided loosely beneath the heater lid for
connection to the drain (refer to Diagram 13).
•
For External models, the outlet is located in the bottom corner below the gas supply connection point.
•
For Internal models, the outlet is located in the bottom corner of the supply air pop hole panel.
•
The condensate is mildly acidic, and shall be run via a PVC pressure pipe (to AS 1477), with an outside
diameter of approximately 27mm, away from the heater to a suitable area (i.e. to above a drain, sewer or pit)
•
Use PVC cement on all joints to prevent any condensate leakage.
•
Do not connect the condensate drain directly to the sewer or below ground level of a storm water drain. A
blockage in the drain system would cause the heater condensate tank to flood with water and shut down. Check
for any additional local drainage codes which may apply.
•
Under no circumstances should it be allowed to run onto electrical connections, earth stakes, copper pipes or
concrete paths. It should also not discharge onto metallic roofs or guttering, however the condensate drain may
terminate into the vertical section of a downpipe above ground level.
•
Tube length should be minimised and a continuous fall of 20mm per metre created. Maximum equivalent tube
length of 12m is recommended (or increase diameter size).
•
Under no circumstances should any part of the tube sag or run uphill.
•
Special consideration is required for installation in areas experiencing sub-zero temperature as condensate
could freeze in the drain. In these cases, larger diameter drainage piping is required.
•
Approximately 2 to 3 litres per hour of condensate may be produced under continuous running conditions,
depending on the size of the heater.
Note: It is important that the above guidelines are adhered to as incorrect drainage may cause serious damage to the heater or its
surroundings.

CONDENSATE DRAIN
7.1.1 Fitting Condensate Drain to Internal Units
a. Fit the barbed connector to the flexible condensate hose (refer to Diagram 13 Internal Fitment).
b. Fasten the hose to secure the barbed connector to the flexible hose.
c. Fit the DN20 pressure pipe drain to the barbed connector.
7.1.2 Fitting Condensate Drain to External Units
a. Fit the DN20 pressure pipe drain into the connector (refer to Diagram 13 External Fitment).
