Installing the water heater
Ensure the water heater model and serial number is copied legibly from the
data plate, left hand side of the appliance, to the sticker on the inside of the
recess box cover—this must be done. The model and serial numbers are
required for servicing, troubleshooting, warranty claims, and parts supply.
Installation
1. Remove the two M5 nylock nuts from the
fixing studs of the box.
2. For Rinnai A-Series models ONLY, remove
the existing lower water heater bracket,
secured with two screws and replace with
the one provided in the kit.
This allows the water heater to line up with
the fixing holes of the recess box.

3. Insert the upper mounting bracket of the
water heater into the bracket slot.
4. Push the appliance up until the lower
mounting bracket aligns with the fixing
studs and secure with the two nylock nuts
removed in step 1.

5. Select the locations for the pipe and
electrical entry to the box. Remove the
blanking plugs from the holes that will
be used and replace with the grommets
supplied, otherwise use the supplied
grommets for other drilled holes. The pipe
entry points are elevated to prevent water
ingress.
6. Complete the gas and water connections.
It is recommended that flexible gas and
water connectors are used to make the
final connections—this allows the water
heater to be removed if necessary without
having to cut the pipework.
7. Install an approved weatherproof electrical
general power outlet (GPO). This can be
installed inside the box in accordance with
AS/NZS 3000 electrical wiring rules.
8. Commission the water heater in
accordance with the commissioning
checklist supplied with the Rinnai
INFINITY.
9. Attach the warning label supplied with the
recess box to the front panel of the water
heater.
10. Install the recess box cover by ensuring
the four locking clips have securely
engaged.
Also secure the cover to the body of the
recess box with the two screws provided
in the kit—these come screwed into the
middle of the recess box. These are needed,
especially in windy areas, to prevent the
cover being blown off.
11. Use an approved solution to seal the box,
cavity and any penetrations, including any
pipe and electrical penetrations.
