The maximum temperature which
can be selected at the Bath Control
is 50%. This is to help reduce the
risk of burns from hot water.
A different temperature can be
stored in the system memory of
the Bath and Kitchen Controls.
Burns from hot tap water can result
in very severe injuries to young
children.
Hot water at 65’C (the average hot
water temperature in Australia) can
severely burn a child in less than
half a second. At 50°C it takes five
minutes.
Burns can happen when children
turn on the hot water tap and they
are under it, or when they are placed
into a bath which is too hot.

Excessively hot water is dangerous, especially for young
children and the infirm. The Infinity 16 allows you to
control the temperature of your hot water to‘safe levels.
Do stay with children whenever they are
in the bathroom. (Take the phone off the
hook).
Do take them out of the bathroom if you
need to answer the phone or door.
Do test the temperature of the water with
your elbow before placing your child in
the bath.
Do make sure that the tap is turned off
tightly.
Do consider setting your Infinity at a
maximum temp of SO’C.(Contact Rinnai.)
Do install a child proof tap cover OR,
Do install a child resistant tap.
Water temperature over 50% can cause
severe burns instantly or death from
scalds.
Children, disabled, and the elderly are at
highest risk of being scalded.
Feel water before bathing or showering.
Don’t leave a toddler in the care of
another small child. The older child may
not have set the water temperature to a
safe level.
*Consider child-resistant taps or
inexpensive tap covers, both of
which prevent a small hand
being able to turn on the tap.
*Consider reducing the
temperature of the water
coming from the hot tap to
50°C.
This approach can be extremely
valuable because it requires a
one time action for a long-term
reduction in the risk of scalds.
This type of automatic protection
is important during times when a
parent or carer has been
distracted.

1. REMOVE CLOTHING
Remove all wet clothing quickly, as clothing retains the heat.
2. APPLY COLD WATER FOR 30 MINUTES
Immediately submerge the burnt area in cold water for SO minutes to reduce the
heat in the skin, preventing deeper burning.
Never use butter, oils, ointments to cover the burn as they may retain the heat.
Never use ice. Children can be dangerously chilled in iced water.
3. KEEP THE CHILD WARM
Place a blanket around your child.
4. SEEK MEDICAL ADVICE
Seek medical advice if the scald involves the face or hands or is larger than
your palm.

n The Infinity 16 is an externally mounted, power flued appliance. IT MUST ONLY
BE FITTED OUTSIDE THE BUILDING.
w When determining a suitable position for thelnfinity 16, the length of hot water
pipe runs should be taken into consideration. In principle, the Infinity 16 should
be as close as possible to the most often used taps, or in acentral location between
taps, showers etc.
n Minimum mounting height from the ground is 1500 mm.

PIPESIZING IS IMPORTANT.
This guide will help you IO size the gas pipe for this appliance correctly.
Calculate the length of pipework and total load in MJA.
Shaded boxes indicate MJlh capacity of pipe.

W INFINITY 16
A 230V weatherproof earthed power point is required within 1500 mm of the
infinity 16.
The Infinity 16 weighs 15 kg, and the wall on which it is lo be mounted must be
capable of supporting it and the pipework. Ensure that suitable fixing screws or
bolls are used to secure the Infinity 16 to the wall. Bracket and fixing hole locations
are shown on page 24.
The top bracket has a keyhole slot so that the Infinity 16 can be positioned by
hanging it on one screw, then the other screws can be secured.
After determining the most suitable position, fix the Infinity 16 to the wall.
Connect hot and cold water pipes. An approved gate valve MUST BE FITTED to
the cold water inlet. In areas where the waler pressure is over 1000 kPa, a
pressure limiting valve must also be fitted.
Water connections are P&/15. Locations are shown on page 24.
Connect the gas. CHECK PIPE SIZING REQUIREMENT USING AN APPROVED
PIPE SIZING CHART.
The Infinity 16 uses 125 MJh of gas. IF THE GAS PIPE SIZE IS INSUFFICIENT,
THE CUSTOMER WILL NOT GET THE FULL PERFORMANCE BENEFIT. An
approved isolation valve MUST BE FITTED to the gas inlet. Connection size is
FP/4/20. This is not an indication of the size of pipe required.
The Infinity 16 waler heater is not suitable for use as a pool heater.
n REMOTE CONTROL
The Remote Control enables the customer to control the functions of the Infinity 16
from inside the house. Before fitting the Remote Control, determine the most
convenient position for installation where the customer will benefit the most.
The MC-33-1A Kitchen Control is intended to be fitted in the kitchen or other
convenient area where the majority of hot water is being used.
An optional BC-451A Bath Control is intended to be fitted conveniently close
to the shower, in the bathroom, en-suite or other area where the customer
requires priority over water temperature selection.
The BC-451A Bath Control enables the person in the shower/bath area to lock in
the selected water temperature, so that the temperature cannot be changed from
the MC-33-1A Kitchen Control.

H When deciding on the best position(s) for the Remote Control(s), the following
points should be taken into consideration.
1. Fit the Remote Control(s) out of reach of children. (Suggested height from floor-
1500 mm).
2. Avoid positions where the Remote Control will become hot (eg: over hotplates,
near ovens or heaters.
3. If possible, avoid direct sunlight (The Digital Monitor is difficult to read in direct
sunlight).
4. Avoid areas where Remote Control will be affected by oil splashing or cooking.
5. The BC-451A(Optional) Bath Control is water resistant, however it should not be
positioned where it may be splashed directly (ie: shower recess).
6. The cable to the Remote Control only carries12 V DC (extra low voltage),
7. Cable should run back to the Infinity 16 from the Remote Control, or cables
should run between the Controls then back to the Infinity 16.
Suggested cable arrangments are shown below.
The installation in every application will vary, therefore the Remote Control cable has
been provided so that you may cut the length accordingly and fit the horse shoe lugs,
ensuring a good connection.
