Connecting Condensate Drain Tube To Heater - Rinnai RHFE-750ETR Installation Manual

CONNECTING CONDENSATE DRAIN TUBE TO HEATER

Condensate Drain Kit
A condensate kit is provided with the heater and will need to be
installed for "Internal Wall" flue installations or other vertical flue
installations that will require draining of the condensate products
back into the heater.
Failure to install the condensate kit correctly may
cause damage to the heater and flue system.

barb is required
1. Insert the barbed end of the condensate tube into the condensate drain hose, ensure that the barb penetrates
the hose by at least 10mm.
2. Locate the condensate tube insertion point, which is a rubber grommet found at the rear of the heater to the
right of the combustion air hose connection.
Insert the condensate tube through the rubber grommet until you reach the 90° bend.
3. Uncoil the condensate drain hose and secure it to the rear of the heater using the upper screw of the
combustion fan cover and the wire tie provided.

Before connecting the condensate drain hose to the condensate trap ensure that there are no kinks
in the condensate drain hose. Also ensure that the path of the condensate drain hose is kept it
CAUTION
away from hot surfaces.
4. Connect the free end of the condensate drain hose to the rubber drain outlet of the condensate trap by pushing
the hose inside the rubber connection to a minimum of 20mm but not greater than 30mm.
Inserting the condensate drain hose into the rubber drain outlet of the condensate trap more than
30mm can cause blocking of the drain-way.
CAUTION
Installation Of Condensate Tray
5. Place the condensate tray into the heater "short end first" making sure that the tray is centred under the end
of the condensate tube that was installed in step 2.
