Description of the boiler
Room sealed boiler
The boiler retreives its
combustion air from outside
then discharges the flue
gasses to the outside.
Condensing
Retrieves heat as much as
possible from the flue gasses.
Water condensates on the
heat exchanger.
Modulating
Installation & Servicing Instructions Rinnai E-Series
Stepless higher or lower
burning according to the heat
demand.

The Rinnai E50C boiler is a room sealed, condensing and modulating central heating
boiler, with an integrated DHW fascility.
The boiler is provided with a compact stainless steel heat exchanger with smooth
tubes. This design is a well engineered principle using durable materials.
The boiler burns gas for supplying heat. The heat is transferred in the heat exchanger
to the water in the central heating system. By cooling down the exhaust gases
condensate is formed. This results in high efficiency. The condensate, which has
no effect on the heat exchanger and the function of the boiler, is drained through a
condensate collector trap.
The boiler is provided with an intelligent control system (CMS Control Management
System). The boiler anticipates the heat demand of the central heating system or the
domestic hot water facility system.
When an outdoor sensor is connected to the boiler it will operate weather dependantly
using outdoor reset. This means that the boiler control measures the outside
temperature and supply temperature. With this data the boiler calculates the optimal
supply temperature for the installation.

Boiler system flushing (Not Boiler heat exchanger)
When replacing an existing boiler the heating system should be flushed with
the old boiler in place before the new boiler is added to the system. If the old
boiler has already been removed a bypass must be piped in when the new boiler
is installed in order to facilitate the flushing of the system.
The boiler must be valved off from the system, while the system is flushed. No
system cleaner should ever enter the boiler heat exchanger due to its caustic
nature which could damage the heat exchanger.
1. Close the shutoff valves on both the supply and return connections on the plumbing
kit (V1 and V2).
2. Open the bypass valve (V4).
3. Connect pump outlet hose (H1) to the purge station (BD1) and connect H2 to the
inlet of the pump and place the other end in the pail.
4. Connect drain hose (H3) to the return side purge station (BD2).
5. Pour the system cleaner into a pail and follow the system cleaner instructions on
circulation time and volume to be added to the system.
6. Close the valve (V3)
7. Operate the pump (P1) and circulate the cleaner through the system for required
time as established by the cleaner manufacturer.

The boiler has a self-adjusting and self-protecting control system for the load and the
pump capacity. By this means, the temperature difference between the supply and return
water is checked and controlled.
If the installation resistance is over the stated value; the load will be adjusted until
an acceptable temperature difference between supply and return water has been
obtained. If, after this, the temperature difference is still not acceptable then the boiler
will switch off and wait until an acceptable temperature has arisen.
If an unacceptable temperature is detected, the control will repeatedly try to achieve
water flow over the boiler. If not the boiler will switch off.
As standard the boiler is provided with a water filter in the return pipe of the boiler,
so that debris from the central heating water is prevented from affecting the boiler.

NOTICE
An approved pressure relief valve is required by Rinnai for all water heating
systems.
The relief valve must comply with the standard for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems ANSI Z21.22 and/or the standard
Temperature, Pressure, Temperature and Pressure Relief Valves and Vacuum
Relief Valves, CAN1-4.4.
The relief valve must be rated up to 150 psi and to at least the maximum BTU/hr
of the appliance.
The discharge from the pressure relief valve should be piped to the ground or into
a drain system to prevent exposure or possible burn hazards to humans or other
plant or animal life. Follow local codes. Water discharged from the relief valve
could cause severe burns instantly, scalds, or death.
The pressure relief valve must be manually operated once a year to check for
correct operation.
The relief valve should be added to the hot water outlet line according to the
manufacturer instructions. DO NOT place any other type valve or shut off device
between the relief valve and the combi boiler.
Do not plug the relief valve and do not install any reducing fittings or other
restrictions in the relief line. The relief line should allow for complete drainage of
the valve and the line.
If a relief valve discharges periodically, this may be due to thermal expansion in a
closed water supply system. Contact the water supplier or local plumbing inspector
on how to correct this situation. Do not plug the relief valve.
Rinnai does not require a combination temperature and pressure relief valve for
this appliance. However local codes may require a combination temperature and
pressure relief valve.
If a combi boiler is installed in a closed water supply system, such as one having
a backflow preventer in the cold water supply line, means shall be provided to
control thermal expansion. Contact the water supplier or local plumbing inspector
on how to control thermal expansion.
Programming domestic hot water preheat
When plate warming is selected the brazed plate heat exchanger is kept warm and
this reduces the wait time for domestic hot water by approximately 1 minute. When
this setting is turned off the wait time for DHW is increased by approximately 1 minute.
Plate warming can only be deactivated when the flow switch accessory (part
number 805000043) has been installed. If no flow switch is installed and
parameter 36 is altered from the factory setting no DHW production will be
possible.
If plate warming is selected consider the following.
This product is a domestic hot water priority boiler; therefore continuous flow
in the DHW system (perhaps due to a leaky fixture) may cause the boiler to
remain in DHW mode — thus preventing the heating system from adequately
functioning. In the event the DHW system has a leak, this feature should be
turned off until this problem can be corrected.
This selection can be done with the first digit of Parameter 36.

See chapter 10 how to change a parameter.
The domestic hot water preheat setting is designed to increase the comfort of the
home owner and reduce water consumption by reducing the wait time for hot water
at the fixture. This comfort setting will create a slight increase in the gas usage of the
boiler, but this will be offset by the reduction in wasted water at the fixture.
6.6 Condensate drain pipe
This boiler produces condensate. Condensate must be drained otherwise the boiler
will not function and can cause product or property damage.
The condensation drain pipe should be connected to a drain in the building by means
of an open connection. By this means the possibility of drain gases effecting the boiler
is prevented. The drain connection should have a minimum diameter of 1.3" / 32mm.
Install the condensation drain pipe according to applicable local code.
If the condensate outlet of the boiler is lower than the public sewage system a
condensate pump must be used.
The condensate produced by the boiler has a pH value between 3 and 4.
Install a neutralization unit if required by local code. It is recommended, but not
required to install a condensate neutralizer. Rinnai offers a condensate neutralizer
designed to work with all boiler models. The condensate neutralizer kit comes with
all the necessary fittings and mounting material. PVC pipe must be supplied by the
installation contractor.

- Room Air System (outdoor combustion air)
The boiler can use room air for combustion. If this option is selected the boiler must
be kept in initially standard parallel vent system. A single exhaust pipe can then be
fitted. It is required to use a room air filter (Part nr. 808000025) when using indoor
air for combustion. See chapter 6.7.3.2 for installation. The maximum permissible
pipe length is set out in table 9, chapter 6.7.6.

The whole route of the vent system must be installed upwards, never downwards,
completely nor partly.
NOTICE
Place pipe supports every 4 feet (1219 mm) of horizontal run, beginning with
the support near the boiler to prevent movement in fittings and allow boiler to
be free from any strain or weight on boiler or fittings.
NOTICE
The terminal should be located where dispersal of combustion products is not
impeded and with due regard for the damage or discoloration that might occur
to building products or vegetation in the vicinity (see fig 15 and 16).
NOTICE
In certain weather conditions condensation may also accumulate on the outside
of the air inlet pipe. Such conditions must be considered and where necessary
insulation of the inlet pipe may be required.

WARNING
Do not overcompensate the boiler by setting a higher value than calculated,
otherwise the boiler could be damaged.
6.7.8 Room Air System (indoor combustion air)
When using indoor air, Rinnai strongly recommends the use of an indoor air
filter, P/N 808000025.
!
This boiler requires adequate combustion air for ventilation and dilution of flue
gases. Failure to provide adequate combustion air can result in unit failure, fire,
explosion, serious bodily injury or death. Use the following methods to ensure
adequate combustion air is available for correct and safe operation of this boiler.
WARNING
Important: Combustion air must be free of corrosive chemicals. Do not provide
combustion air from corrosive environments. Appliance failure due to corrosive air is
not covered by the limited warranty.
Combustion air must be free of acid forming chemical such as sulfur, fluorine and
chlorine. These chemicals have been found to cause rapid damage and decay and
can become toxic when used as combustion air in gas appliances. Such chemicals
can be found in, but not limited to bleach, ammonia, cat litter, aerosol sprays, cleaning
solvents, varnish, paint and air fresheners. Do not store these products or similar
products in the vicinity of this boiler.
Unconfined Space:
An unconfined space is defined in NFPA #54 "as a space whose volume is not less
than 50 cubic feet per 1000 Btu/hr (4.8 m3 per kW per hour) of the aggregate input
rating of all appliances installed in that space. Rooms communicating directly with
the space in which the appliances are installed, through openings not furnished with
doors, are considered a part of the unconfined space." If the “unconfined space”
containing the appliance(s) is in a building with tight construction, outside air may
still be required for proper operation. Outside air openings should be sized the same
as for a confined space.

Confined Space:
(Small Room, Closet, Alcove, Utility Room, Etc.)
A confined space is defined in the NFPA #54 as "a space whose volume is less than
50 cubic feet per 1000 Btu/hr (4.8 m3 per kW per hour) of the aggregate input rating
of all appliances installed in that space." A confined space must have two combustion
air openings. Size the combustion air openings based on the BTU input for all gas
utilization equipment in the space and the method by which combustion air is supplied:
Using indoor air for combustion
Using outdoor air for combustion
Louvers and Grills
When sizing the permanent opening as illustrated in figure 17, consideration must be
taken for the design of the louvers or grills to maintain the required free area required
for all gas utilizing equipment in the space. If the free area of the louver or grill design
is not available, assume wood louvers will have 25% free area and metal louvers or
grills will have 75% free area. Under no circumstance should the louver, grill or screen
have openings smaller than ¼”.
Example:
Wood: 10 in x 12 in x 0.25 = 30 in2
Metal: 10 in x 12 in x 0.75 = 90 in2
Location
To maintain proper circulation of combustion air two permanent openings (one upper,
one lower) must be positioned in confined spaces. The upper shall be within 12 inches
of the confined space and the lower opening shall be within 12 inches of the bottom
of the confined space. Openings must be positioned as to never be obstructed.
Combustion air provided to the boiler should not be taken from any area of the structure
that may produce a negative pressure (i.e. exhaust fans, powered ventilation fans).

Using Indoor Air For Combustion
When using air from other room(s) in the building, the total volume of the room(s) must
be of adequate volume (Greater than 50 cubic feet per 1000 Btu/hr). Each combustion
air opening must have at least one square inch of free area for each 1000 Btuh, but
not less than 100 square inches each.
Using Outdoor Air For Combustion
Outdoor air can be provided to a confined space through two permanent openings,
one commencing within 12 in. (300mm) of the top and one commencing within 12”
(300mm) of the bottom, of the confined space. The openings shall communicate to
the outside by one of two ways:
directly through horizontal ducts
indirectly through vertical ducts
When communicating directly with the outdoors through horizontal ducts, each
opening shall have a minimum free area of 1 in2/2000 Btu/hr (1100 mm2/kW) of
total input rating of all appliances in the confined space.
Note: If ducts are used, the cross sectional area of the duct must be greater than
or equal to the required free area of the openings to which they are connected.
When communicating indirectly with the outdoors through vertical ducts, each
opening shall have a minimum free area of 1 in2/4000 Btu/hr (550 mm2/kW) of
total input rating of all appliances in the confined space. Combustion air to the
appliance can be provided from a well ventilated attic or crawl space.

NOTICE
The Rinnai room thermostat and controls must be connected to their allocated
connections. All other types or makes of room thermostats or controls which
are used must have a Volt free contact.
When using an on/off thermostat or control, it may be necessary to calibrate the
anticipating resistance to prevent too high temperature fluctuations. As a standard
rule this means mercury thermostats. This resistance wire is present in the Control
Tower and must be connected to terminals 23 and 27. The anticipating resistance in
the room thermostat has to be set at 0.11 A.
For more detailed questions regarding the components which are not supplied, the
distributor should be contacted.
When wiring an RS100 it is suggested that a jumper be placed on terminals 22
and 23 so that in the event the control is damaged the boiler will still fire based
on outdoor reset.
A jumper should also be used when commissioning or trouble shooting the
boiler.
Power stealing thermostats cannot be connected to terminals 22 and 23.

Boiler controls
The boiler is provided with a fully automatic microprocessor control, called CMS
Control Management System. This control simplifies operation by undertaking all
major control functions. Initially when power to the unit is switched on it will remain on
standby. There is no indication LED on, until one of the program buttons is pressed.
The control panel display will show the relevant state. When the boiler installation is
empty the display will show FILL.
The various parameters can be called up in two ways:
The Good-state or standard read out
The first way shows a simple display read out.
The boiler in operation will always show 'Good'. When a message is necessary this
will be shown instead of Good.

On a call for heating or hot water the control system will select the required water
control temperature. This water temperature is called the T-set value. On a call for
central heating the boiler ignites first at low input. The input is then changed slowly to
match the load required. The boiler operates in this way to avoid excessive water noises
and temperature overshoot. On a call for domestic hot water supply the T-set value
of central heating return water temperature is monitored. Depending on the amount of
domestic water which is withdrawn from the DHW fascility, the central heating return
water temperature, from which the input is adjusted, will vary.

WARNING
CAUTION
Observe the following rules of safety:
- All work on the unit must take place in a dry environment.
- Rinnai units may never be in operation without their housing, except in connection
with maintenance or adjustments (see Chapter 12 and 13).
- Never allow electrical or electronic components to come into contact with water.
NOTICE
Carry out the following tasks in connection with maintenance, etc. to an alreadyinstalled unit:
- Shut down all programs
- Close the gas shut off valve
- Shut off the power at the main power switch
- Close the service valves (system supply and return)
NOTICE
Take note of the following when maintenance or adjustments are needed:
- The unit must be able to function during these activities; for this reason, the unit’s
supply voltage, gas pressure and water pressure must be maintained. Ensure that
this is not a source of potential danger during these activities.
Following maintenance or other activities; always check the installation of all
parts through which gas flows (with bubble test using leak-search spray).
9.1 Requirements of the water system
Before filling the heating system, the complete system, including all zones, must be
thoroughly cleaned and flushed to remove sediment. Flush until clean water runs
free of sediment. Rinnai suggests using an approved system cleaner to flush the
system, but not the boiler. Always use Rinnai approved antifreezes. See the list at
the end of this chapter. Never use reverse osmosis, D.I., or distilled water for filling
the heating system.
Installation & Servicing Instructions Rinnai E-Series

WARNING
Do not use petroleum-based cleaning or sealing compounds in the boiler
system. Damage of seals and gaskets in boiler and system could occur,
resulting in property damage.
The central heating installation needs to be filled with potable water.
!
WARNING
Use only potable water or approved glycol for filling the heating system.
When the water hardness of the filling water exceeds > 10.5 gpg (200 mg/L) and
the volume of the installation > 20L/kW (5.2 gallons/3,412 BTU) the water has to
be treated until below the maximum value of 10.5 gpg (200 mg/L).
The pH value of the installation water must be between 6.5 and 8.5.
Check the pH value using proper equipment or by having the water analyzed by a
water treatment company.
If pH differs from above, contact Rinnai engineering for further assistance.
i
NOTICE
Component or product damage as a result of failing to adhere to the water
quality requirements will not be covered by the limited warranty.
Freeze protection
Freeze protection for new or existing systems must use glycol that is specially
formulated for this purpose. This includes inhibitors, which prevent the glycol from
attack the metallic components. This should be for multi-metallic components.
Make certain to check that the system fluid is correct for the glycol concentration and
inhibitor level. The system should be tested at least once a year and as recommended
by the producer of the glycol solution. The allowed maximum concentration is 50%.
i
NOTICE
!
WARNING
i
NOTICE
Use only Rinnai approved inhibitors. See below for an approved list of inhibitors.
Use only inhibited propylene glycol solutions, which are specially formulated
for central heating systems. Ethylene glycol is toxic and can attack gaskets
and seals used in the boiler and system. Approved glycols are listed below.
Additives in the installation water are not permitted.
Approved antifreeze: • Rhomar RhoGard Mutli-Metal (AL safe)
(max. concentration 50%) • Noble Noburst AL
Approved system cleaner: • Noble Noburst Hydronic System Cleaner
• Rhomar Hydro-Solv 9100
• Fernox F3 Cleaner
• Sentinel X400
The system cleaners from NoBurst, Rhomar, and Fernox are not to be used in
the boiler. The boiler must be closed off (valved off) from the rest of the system
or not connected while the cleaners are in the system. The system should then
be drained and then thoroughly flushed with clean water to remove all the
system cleaner.
Approved inhibitors: • Rhomar Pro-tek 922
• Noble Noburst AL inhibitor
• Sentinel X100
9.2 Filling the heating system
For filling or topping off the installation you use the filling loop according to the following
procedure:

14 Check the water pressure and if necessary top it up to 16 to 18 PSI
15 Close the filling loop;
16 Press the ‘STEP’-button;
17 Be sure that the filling loop is closed.
18 After the automatic de-aeration program (A XX) is finished the boiler will return to
the Good state or Technical read out.
Check the water pressure regularly and top off the installation when necessary.
The working pressure of the installation should be between 16 and 18 PSI when the
system is cold.
i
NOTICE
It can take a while before all air has disappeared from a filled installation.
Especially in the first week noises may be heard which indicate the presence
of air. The automatic air vent in the boiler will remove this air, which means the
water pressure can reduce during this period and therefore topping off with
water will have to be done.
During normal use the following messages can occur with the necessary follow up:
Water pressure is too low (<10 PSI), FILL
indication remains continuously visible,
the boiler is taken out of operation. The
installation needs to be topped off.
Water pressure is too low (<12 PSI),
flashing FILL will alternate with indication
of water pressure, boiler power of 50%
is possible. The installation needs to be
topped off.
Water pressure is too high (>42 PSI),
if HIGH indication remains continuously
visible, the boiler is taken out of operation.
The installation pressure needs to be
decreased by draining water.
9.3 Hot water supply
Installation & Servicing Instructions Rinnai E-Series
Apply the water pipe pressure to the DHW fascility (open main valve and/or stop
valve of the safety group).
48
Vent the DHW fascility and the hot water installation by opening a hot water shut off
valve. Leave the shut off valve open for as long as required until all air has disappeared
from the DHW fascility and the pipes and only water is flowing from the shut off valve.

Some situations require turning the entire boiler off.
By switching off the three buttons with the LED's for central heating, hot water and
pump program (
,
or
), the boiler is switched off. Do not shut off the power
of the boiler, which means the circulation pump and the three-way valve are activated

Commissioning
Work on the boiler must be carried out by a licensed professional, using
correctly calibrated instruments with current test certification.
These installation instructions are intended for licensed professionals, who
have the necessary knowledge and are approved for working on heating and
gas systems.
NOTICE
Before the boiler is fired, ensure that the boiler and the system are well de-aerated
and free of air. Purge the gas line between the gas meter and the boiler.
!
WARNING
Failure to properly commission the boiler as described in section 13 may
result unreliable burner operation, reduced component life, and unsafe boiler
operation.
i
NOTICE
The boiler and its individual shut off valve must be disconnected from the
gas supply piping system during any pressure testing of that system at test
pressures in excess of 1/2 PSI (3.5kPa).
To commission the boiler the casing has to be removed.
- remove the 4 screws A,B,C and D in the quick releases of the casing (figure 25);
- remove the screw E behind the door on the front of the casing (figure 25);
- remove it towards the front.
Installation & Servicing Instructions Rinnai E-Series
Installing casing

figure 25
The boiler settings, such as burner pressure and adjustment of the air quantity are
unnecessary in most cases, due to the fact that the boiler operates with a zero pressure
control. This means the correct gas quantity is controlled by the suction operation of
the fan. The fine adjustment of the zero pressure, which is carried out at the factory
is once-only, which means that adjusting of this value is unnecessary. Only in case of
replacing of the gas valve, venturi and/or fan will the zero pressure adjustment have
to be checked and, if necessary, adjusted to the right value.
!
WARNING
The venturi must always be checked and adjusted when it is out of range see
section 12.3 on O2 adjustment.
!
DANGER
Always check the installation of all parts through which gas flows (by bubble
test using leak-search spray).
Pump commissioning procedure should be followed before the boiler is fired for the
first time:
1. Remove the vent pump screw
2. Use a small flat head screw driver to ensure the impeller spins freely.
3. When the impeller spins freely and water exits though the vent port the pump is
ready for operation.
4. Replace the vent screw
During the commissioning of the boiler the Rinnai Installation, Commissioning, and
Service card must be filled out.

DANGER
Before leaking testing the boiler, ensure all parts of the boiler such as
electronics and wiring are properly covered and protected from the leak
testing agent.
Do not spray the leak testing agent onto cables, plugs, electrical connection
lines or electronic circuit boards. Do not allow it to drip onto them either.
Leaks may be caused to pipes and screw connections during commissioning
and maintenance activities.
- Carry out a proper leak test.
- Only use approved leak detection agents for leak detection.
- Disconnect the heating system from the power supply.
- Check the exterior tightness of new conduit sections up to and including the direct
sealing point on the gas burner fitting. The maximum test pressure allowed on
the input of the gas burner fitting is 14 inch W.C. (35mbar).

Common venting guidelines
Installation & Servicing Instructions Rinnai E-Series
Do not common vent with the vent pipe of any other boiler or appliance. However,
when an existing boiler is removed from a common venting system, the common
venting system is likely to be too large for proper venting of the appliances remaining
connected to it. At the time of removal of an existing boiler, the following steps shall
be followed with each appliance remaining connected to the common venting system
placed in operation, while the other appliances remaining connected to the common
venting system are not in operation:
82
(a) Seal any unused openings in the common venting system.
(b) Visually inspect the venting system for proper size and horizontal pitch and determine
there is no blockage or restriction, leakage, corrosion and otherdeficiencies which
could cause an unsafe condition.
(c) Insofar as is practical, close all building doors and windows and all doors between
the space in which the appliances remaining connected to thecommon venting
system are located and other spaces of the building. Turn on clothes dryers and any
appliance not connected to the common venting system. Turn on any exhaust fans,
such as range hoods and bathroom exhausts, so they will operate at maximum
speed. Do not operate a summer exhaust fan. Close fireplace dampers.
(d) Place in operation the appliance being inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate continuously
(e) Test for spillage at the draft hood relief opening after 5 minutes of mainburner
operation. Use the flame of a match or candle, or smoke from acigarette, cigar or
pipe.
(f) After it has been determined that each appliance remaining connected to the
common venting system properly vents when tested as outlined above,return
doors, windows, exhaust fans, fireplace dampers and any other gas burning
appliance to their previous condition of use.”
(g) Any improper operation of the common venting system should be corrected so the
installation conforms with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/
or CAN/CSA B149.1, Natural Gas and Propane Installation Code. When resizing
any portion of the common venting system, the common venting system should
be resized to approach the minimum size as determined using the appropriate
tables in Part 11 of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or
CAN/CSA B149.1, Natural Gas and Propane Installation Code.
