HEATER INSTALLATION
1. UNPACKING THE APPLIANCE
The heater components are supplied in three main cartons. These cartons contain the heater body
assembly, the fascia and the burner media for the contents of each carton refer to “CARTON
CONTENTS / ITEM CHECKLIST” on page 1.
Check for damage and missing parts. If the heater is damaged or missing any parts, contact your
supplier for advice. Before installing the appliance, check it is labelled for the correct gas type (see
label on top rear of heater). Refer to local gas authority for confirmation of gas type if you are in doubt.
Remove the heater body assembly from the engine carton and position in front of the enclosure
opening.
The heater does not come supplied with flue components. These are purchased separately.
ONLY Rinnai RHFE-752ETR flue components can be used with this appliance.
2. CONNECTING THE APPLIANCE TO THE CONSUMER PIPING
240 VOLTS, RISK OF ELECTRICAL SHOCK! Isolate the electricity supply before removing
any panels.
Remove the right-hand side access panel
by removing the four
retaining screws
.
Extend the flexible gas connection
through the gas fitting access
point
to the outside of the heater body.
Position the appliance in front of the enclosure so that the end of the
consumer piping aligns with the gas fitting access point
.
Securely connect the flexible gas connection
to the consumer
piping. Test all connections for gas leaks.
Use a soapy solution to test all gas connections. If a leak
is present bubbles will form at the leak point. When
finished remove any residue with a rag. Prevent any
soapy solution from coming in contact with the electrical
components.
Replace the right-hand panel
and secure with the four retaining
screws .
3. OPENING THE FLUE SYSTEM ACCESS PANEL
Unscrew the flue system access panel
(two screws)
located
inside the top left-hand corner of the appliance, slide this panel to
the right behind the convection fan
.
Remember to position the air inlet hose so that it can still be
accessed once the appliance is moved into the enclosure.
Tie a piece of string to the air hose and pass this
through the flue system access opening. This will
allow the air inlet hose to be pulled up into
position as required.
