Condensate Trap and Condensate Drain Line
Where the installation requires a Condensate Trap and condensate drain line:
1. Remove the clamp and rubber cap from the condensate drain spigot on the water heater flue outlet
assembly.
2. Locate the Condensate Trap in a suitable position adjacent
to the water heater.
The loop of the condensate trap MUST BE below the spigot
of the condensate drain section to ensure proper drainage.
 Secure to the wall with the pipe saddle supplied.
If required, trim the hose length to suit the installation.
Ensure the structure of the Condensate Trap including the
fixed loop is not altered and the trimmed hose seals to the
spigot.
3. Fill the condensate trap with water.
4. Fit the shorter end of the silicone tube to the 16 mm spigot of
the water heater flue outlet, ensuring a constant fall to the
condensate trap.
 Secure to the spigot with the clamp removed in step 1.
 Ensure the silicon hose is not kinked.
5. Plumb the outlet of the Condensate Trap to drain.
 Ensure the silicon hose is not kinked.
The drain line should be as short as possible, have a continuous fall all the way from the Condensate
Trap to the discharge outlet and have no tap, valves or other restrictions in the pipe work.
The outlet of the drain line must be in such a position that flow can be easily seen, but arranged so the
condensate will not cause injury, damage or nuisance.
Warning: Failure to fill with water may cause flue gasses to escape through the condensate trap. Check
regularly to ensure the condensate trap is filled with water, replenishing when required.
Notes
AS/NZS 3500.4 section 5.12, is used as a guide in preparing the following drainage recommendations.
As the condensate is mildly acidic, copper tube and fittings must not be used as they will corrode.
Use UPVC (Unplasticised Polyvinyl Chloride) or PE (polyethylene) piping.
The outlet of the drain line must be in such a position that flow can be easily seen, but arranged so that
discharge will not cause injury, damage or nuisance.
The drain line must not discharge onto electrical connections, earth stakes, copper pipe, concrete paths
or into a pond.
For a multiple unit installation, refer to “Multiple Water Heater Condensate Trap and Condensate Drain Line
Installation” on page 41.
