About the Demand Rapid system
The thermostat senses the temperature of the water in the cylinder, and
when it drops below the set point the pump is activated. This ow starts the
Rinnai INFINITY continuous ow water heater, which returns the heated
water to the cylinder.
Reset timer
The system is equipped with a reset timer to ensure the pump does not run
continuously. This may occur if the Rinnai INFINITY does not ignite. The
timer will shut off the pump every 30 minutes for a few seconds to ensure
the Rinnai INFINITY resets itself.
Safety devices
For safe operation the cylinder component of the system is tted with:
• Temperature Pressure and Relief (TPR) valve(s), to ensure the water
stays at a safe pressure and temperature.
• Thermostat to maintain the water temperature.
It is important that you do not tamper with or remove these devices. In the
case of the TPR valve(s), do not block or seal the valve(s) or drain pipe(s).
The system must not be operated unless these devices are tted and are in
good working order.
Rinnai INFINITY safety devices; ame failure, boil-dry protection, overheat protection, fusible link,
pressure relief valve and combustion fan rpm check.
Cylinder thermostat setting
To meet the New Zealand Building code requirement1to disinfect water for legionella bacteria2, the
cylinder thermostat has been set to 65 °C.
1 Clause G12.3.9, Acceptable Solution G12/AS1 6.14.3
2 Legionella is a bacterium that can cause Legionnaires’ disease—a severe form of pneumonia
General safety
Power cords
Power leads from the system MUST BE plugged into a weatherproof electrical outlet. If
the power supply cord of the system is damaged it must be replaced by an authorised
person in order to avoid a hazard, using genuine replacement parts from Rinnai. Take
care not to touch power cords with wet hands.
Rinnai INFINITY external ue outlet
• Do not touch or insert objects into the ue outlet
• Keep ammable materials, spray cans, fuel containers, pool chemicals well clear of the system
and ue outlet

Demand Rapid owner & installer guide 12949-B 02-19 | 5
Important
Only a licensed tradesperson can install, adjust, maintain and service this water heating system.
Any work carried out by a non-licensed tradesperson is illegal and will void any warranty.
Catch pan
It is important a suitably drained catch pan (or drain system) is tted where damage could be
caused by discharge from the cylinder. This is a mandatory requirement of the installation. If
damage is caused by a leaking cylinder that has not been installed with a suitable drain system the
owner can seek compensation through the installer or consider claiming on insurance.
In the event of a power failure
The system will not operate without electricity. In the event of a power failure, when power is
restored the water ow may need to be stopped and restarted to get the system working again.
Frost protection
Frost protection1 is tted as standard on all Rinnai INFINITY models. Frost protection operates
automatically, as required, whenever the appliance is connected to the power supply.
If power has failed and there is risk of damage from frost, turn off the gas supply to the unit, and
open a tap slightly to allow ow through the unit. This may prevent damage from freezing. If the
system is not going to be used for an extended period and the power supply is disconnected,
turn off the water and gas supply and arrange for a plumber to drain all water from the system to
prevent frost damage.
Flue outlet discolouration
The colour of the ue outlet on an external Rinnai INFINITY may change over time due to
condensate in the exhaust gases. This is normal. The discolouration will not damage the unit, and
will not affect performance of the water heater.
Do not adjust the thermostat settings
The warranty is not valid unless the following settings remain:
• Rinnai INFINITY 75 °C
• Cylinder set temperature 65 °C
• Cylinder low limit temperature 60 °C
1Frost protection turns on when the temperature inside the unit drops below 3.5 °C and switches off when the temperature reaches
7 °C. The heat inside the unit is provided by ceramic heating elements that stop the water within the pipework of the unit from freezing.

Maintenance and servicing
Hot water systems, like cars, require regular maintenance and servicing. To ensure longevity of
your system we recommend the following.
Period What needs to be done
Every six months TPR valve(s)—operate the easing gear
Annually Inspection and service of the entire hot water system, including
inspection of the ue system (if applicable), cleaning of the INFINITY
inlet water lter, draining and ushing of the cylinder if the water
supply contains excessive levels of silt
TPR valve(s)
Located near the top of the
cylinder—essential for safe
operation. The TPR valve(s)
automatically vent hot water if
the temperature or pressure of
the water in the cylinder gets
too high.
Every six months operate the
easing gear to remove lime
deposits and check that it is
not blocked. As the valve(s)
will discharge hot water,
ensure no one is near the
drain line.
Failure to operate the
relief valve easing gear
at least once every
six months may result
in the water heater
exploding.
Continuous leaking of water
from the valve(s) may indicate
a problem. It is important that
you raise and lower the easing
gear gently. During operation,
if the valve does not discharge
water when the easing gear
is lifted, or does not seal
again when closed, arrange
for an authorised person to
come and inspect the system
immediately.
During servicing of your
system the TPR valve
needs to be checked and/or
replaced. This needs to be
done by an authorised person
at intervals not exceeding
ve years, or more frequently
in areas where the water is
classied as hard.
A TPR valve must not be
replaced with one that has a
higher pressure rating than
that specied for the cylinder.
Maintenance and servicing
Rinnai has a maintenance,
service, and spare parts
network with personnel who
are fully trained and equipped
to give the best advice on
your Rinnai product. Regular
maintenance and servicing
is not covered by the Rinnai
warranty.

Location
System should be installed in accordance with G12 and AS/NZS 3500.4. For servicing and
maintenance, please allow sufcient room for access of all components of the system.
Ensure the hot water system is installed in a corrosive free environment and free from chemicals
as this could potentially create an atmosphere that attacks the Rinnai INFINITY water heater.
Base requirements
System should be installed in a at level surface of sufcient strength to support the weight of the
Demand Rapid system when full of water.
The frame must be secured to the oor using anchor bolts (not supplied). The water heating
system must also be suitably restrained against seismic activity, ‘G12/AS1 Figure 14’.
Access to the system
All components of the system must be installed to ensure access can be gained without hazard or
undue difculty for inspection, repair, replacement, or operational purposes. Sufcient clearances
shall allow access to remove all serviceable components.
Where the system is not accessible, the Rinnai warranty will not cover any additional costs caused
by access difculty. The system must be accessible without the use of a ladder or scaffold.
Catch pan
It is important a suitably drained catch pan (or drain system) is tted where damage could be
caused by discharge from the cylinder. This is a mandatory requirement of the installation. If
damage is caused by a leaking cylinder that has not been installed with a suitable catch pan and
drain system the owner can seek compensation through the installer or consider claiming on
insurance.
• Drain valve
Provision must be made to drain the cylinder if required for servicing.
• Drain lines
These must be installed in accordance with AS/NZ 3500 and/or G12/AS1
Rinnai INFINITY ue clearances
Flue clearances must comply with AS/NZS 5601.1.
Demand Rapid systems installed with internal units must use a Rinnai approved ue system.
Condensate drain required for DD1212i315
The Rinnai INFINITY EF internal unit generates condensate continuously as a by-product of a
highly efcient gas burner. Provision must be made to drain the condensate to a suitable point of
discharge, refer Appendix 1 on p. 22 for more information.

16 | Demand Rapid owner & installer guide 12949-B 02-19
General installation information
Cold water inlet
32 mm tting on the left hand side of the cylinder, approximately 285 mm above the ground. For
ease of draining it is advisable to t a ‘tee’ piece with a capped valve or drain line between the cold
water isolation valve and cold water inlet connection on the cylinder.
Hot water outlet
32 mm tting on the left hand side of the cylinder. Ensure adequate insulation/lagging is tted to
the hot water pipe to minimise heat loss. Pipe sizing must be sized to allow sufcient water ow to
the hot water xtures.
The Demand Rapid will deliver 75 °C water to the
plumbing system. Ensure the system components are
designed to operate continuously at this temperature.
For installations where the hot water supply temperature
must be lower, one of the following plumbing
modications are required.
1. Install a tempering valve between the inlet and outlet
of the storage water heater to reduce the temperature.
2. Re-plumb the INFINITY gas water heater to the hot
water return connection as shown. This will
reduce the hot water temperature being delivered to
approximately 70 °C.
Pressure limiting valve
500 kPa maximum
Cold water expansion valve
700 kPa maximum
Cylinder thermostat setting
To meet the New Zealand Building code requirement1to disinfect water for legionella bacteria2, the
cylinder thermostat has been set to 65 °C.

2 Legionella is a bacterium that can cause Legionnaires’ disease—a severe form of pneumonia
WARNING
Delivery temperatures
Sanitary xture delivery temperatures
Water temperatures over 55 °C can cause severe scalds. Local regulations must be considered
regarding temperature limitations of hot water supplied to areas used primarily for personal
hygiene. The temperature is limited to 45 °C for early childhood centres, schools, nursing
homes or similar facilities, and 55 °C for all other buildings. To comply with these requirements a
temperature limiting device, such as a tempering or thermostatic mixing valve will be required on
all installations.

Demand Rapid owner & installer guide 12949-B 02-19 | 17
Connections
TPR valve(s)
One TPR valve (two for the DD1212 and DD1250), supplied and tted to a 20 mm tting near the
top of the cylinder.
Relief valve drain lines
Connect an independent 20 mm copper tube relief valve drain line to the TPR valve outlet. Drain
should be installed with a continuous fall toward a visible discharge point over a drain or gully in
accordance with AS/NZS 3500.4 sections 5.8 and 5.9.
• Drain line should not exceed 9 m in length
• Valves or other restrictions should not be installed with the relief vent line
• TPR valve drain line should not be joined to other drain lines
Gas connection
Check gas type of the Rinnai INFINITY matches the gas supply available on site.
Ensure gas pipe sizing is adequate to deliver the required volume/pressure. The pipe size used
on the inlet tting is no indication of the pipe size required. Refer to appropriate pipe sizing chart in
AS/NZS 5601.1.
Gas meter or LPG cylinders and regulator should also be of a suitable size to ensure sufcient gas
supply to the gas installation.
Purge gas line and ensure removal of debris prior to nal connection. Check for gas leaks using
suitable methods as listed in AS/NZS 5601.1

18 | Demand Rapid owner & installer guide 12949-B 02-19
Filling and draining
IMPORTANT
Do not turn on the pump or system until the cylinder is completely full of water. Damage to
the system as a result of not following this instruction will void any warranty.
Filling
1. Flush the cold water inlet pipe to remove any debris before nal connection to the cold water
inlet of the Demand Duo cylinder.
2. Ease the TPR valve open to expel air while the cylinder is lling with cold water.
3. Slowly open the cold water expansion valve on the cold water supply pipe.
4. Allow the cylinder to ll.
5. Check all connections for water leaks and tighten as required.
6. Prime circulating pump before start up.
7. The thermostat on the Demand Duo cylinder is set to 65 °C and the Rinnai INFINITY is set to
75 °C. If the cylinder thermostat does not appear to be set correctly the thermostat may need to
be reprogrammed—contact Rinnai for assistance.
If hotter water is required the cylinder and the Rinnai INFINITY dip switches will need to be
adjusted.
8. Plug 3-core ex into suitably earthed general power outlet (GPO). Turn on power supply. The
thermostat will display the current water temperature in the cylinder, the pump should start and
the Rinnai INFINITY unit should ignite.
9. The Rinnai INFINITY unit will continue to operate until the thermostat reaches 65 °C. Once the
set temperature has been reached the thermostat will turn off the primary circulating pump.
10. When the storage water heater temperature drops below 60 °C the controller switches on the
recirculation pump, which ignites the INFINITY to reheat the water.
Draining
1. Isolate power supply to the Demand Rapid system.
2. Close the cold water isolation valve.
3. Ease the TPR valve open to expel air.
4. Remove cap on the cold water drain valve if no drain line is tted.
5. Connect a hose or something similar to allow water to drain to a safe location.
6. Open cold water drain valve and allow water to drain from the system.
