Rinnai Boil & Brew: Owner and installer guide: 20830-C 03-18
Do not connect the power until there is water flowing freely from the faucet.
Failure to do this may cause the heating element to overheat and fail.
General installation information
1. Mount to the wall
Determine the height of the unit and then
screw in the two top mounting screws
(10 g x 40 mm).
2. Remove the cover
Remove the four cover screws nearest the
back. Remove the cover.
3. Fit unit to the wall
Hang the unit to the wall at the two key hole
fixing points provided at the top of the back
plate. Secure the base with the additional
holes provided.
4. Connect water supply
Connect mains water supply* to the outer,
right hand side ½ BSP connector (marked cold
inlet).
If your water supply contains sand, grit or
other suspended particles, fit an additional
filter (not supplied) in the supply line.
Contaminated water may cause a blockage in
the inlet valve.
* Intended for permanent connection to mains water
supply and not through a hose-set.
5. Connect vent/overflow
Connect a ½ BSP copper tube to the left side
½ BSP vent/overflow connector. This overflow
vent must be arranged so as to divert excess
water, steam, or steam condensation into
the sink, or drain, or to the exterior of the
building.
The vent tube must be unrestricted, be
greater than 5 mm OD (to avoid blockage),
have a continuous fall with a clear open end
and must be left open to the atmosphere. It
cannot be connected to an open plumbing
system. Alternatively, providing that you have
sited the Rinnai Boil & Brew over a sink or
draining board, you can vent directly through
the bottom of the unit through the hole
provided.
Make up and connect your overflow vent.
6. Turn on water supply
Turn on the water supply and check for leaks.
Wait until filled and until water flows freely
from the faucet.
7. Refit the cover
Place the cover over the unit and refit the
four screws. Leave the faucet in the closed/off
position. The unit is now ready for filling.
8. Connect the power and switch on
Only do this if there is water flowing freely
from the faucet as failure to do so could cause
the element to overheat and fail.
9. Flush entire system
Draw off as much water as needed to ensure
the system is completed flushed of any
installation materials.
The Rinnai Boil and Brew is now ready to use.
