Gas Supply
The meter and supply pipes must be sized to deliver the gas rate and pressure given on page 4 The
boiler requires at least a 22 mm (3/4”) gas supply pipe The complete installation, including the meter, must
be tested for gas soundness and purged as described in IS 813:2002
Electrical Installation
The boiler requires a 220/240 V ~ 50
Hz mains supply, fused at 3 A The
boiler must be earthed. The polar-
ity of the supply must be correct as
otherwise the boiler will not operate
properly
There must only be one common iso-
lator, providing complete electrical
isolation, for the boiler and any
external controls Using PVC
insulated cable not less than 0 75
mm² (24 x 0 2 mm) to BS 6500
Table 16, the boiler should be
connected to a fused three pin plug
and unswitched shuttered socket out-
let (both complying with BS 1363), or
a fused double pole switch with a
contact separation of at least 3 mm
in both poles
Wiring external to the boiler must
be in accordance with the current IEE
Wiring Regulations
Note: External controls connected to the boiler must be of the volt free type and are connected to
terminals 40 and 41 as shown above.
Weather Compensation
A temperature sensor for outdoors is available as an optional accessory for the boiler This should be fitted
in an outdoor location which is not exposed to direct sunlight A north facing wall is a good location
If the optional weather compensation sensor is used, it should be connected to terminals 38 and 39 as
shown above using a two core cable If this cable is routed in close proximity to cables carrying mains volt-
ages, then screened cable should be used Contact RVR for more information
When the sensor is connected, the boiler adapts it’s flow temperature to suit the prevailing weather condi-
tions This results in lower energy usage and enhanced comfort
WARNIN ! - Connection of a voltage to any boiler terminals other than the mains
lead will result in destruction of the boiler control panel. The product warranty
does not cover this type of damage.
Clearances and Air Supply
The boiler does not require any air vents for cooling in the room in which it is installed or when installed in a
cupboard or compartment The minimum clearances for servicing must always be maintained Please see
table on page 14 Note: A cupboard or compartment used to enclose the boiler must be designed and
constructed specifically for the purpose

Flue Systems
When the boiler is installed on an external wall, the standard horizontal concentric 60/100 flue kit will normally
be used to flue the boiler This is shown in the diagram
It is often necessary to install a longer flue system to cater for site conditions There are several different flue
system sizes available for the Victrix Zeus 20/27 boiler
Horizontal concentric kit 60 /100
Install the bend with flange (2) on the left hole of the boiler insert-
ing the seal (1) with the round protrusions facing downwards in con-
tact with boiler flange and tighten using the screws supplied with
the kit
Fit the smooth male end of the 60/100 concentric terminal pipe (3)
until it reaches to the stop on the female end of the bend (2), mak-
ing sure the internal and external sealing rings are fitted; this will
ensure the connection is properly sealed Additional extensions
and bends may be installed if required using the same method
Ensure that all seals are fitted and that the outer and inner pipes
are installed so that all joints are perfectly sealed Ensure that the
terminal is installed the right way up
A lubricant may assist in overcoming the friction of the seals Oils
and conventional greases are not compatible with the EPDM seals
used and should never be used for this purpose Talc may be
used Please contact RVR for more information
A rigid supporting clamp should be fitted on each 1 0 metre or 2 0
metre flue extension in all cases The flue system should be inclined at a minimum slope of 1% so that conden-
sate flows towards the boiler The elbow above the boiler is the low point of the flue system and the terminal at
the outside wall is the high point of the system The fall should be continuous over the full length of the flue sys-
tem and the there should be no low points which would allow condensate to build up within the flue pipes This
avoids any drips from the external flue terminal
The maximum possible overall length after the first bend (2)
is 12.9 straight and horizontal meters. See the section on
extended flue design for more information.
Vertical concentric kit 60 /100
Install the concentric flange (2) on the left hole of the boiler in-
serting the seal (1) with the round protrusions facing downwards
in contact with boiler flange and tighten using the screws sup-
plied with the kit
Fit the male end (smooth) of the adapter (3) in the female end of
the concentric flange (2) until it reaches the stop on the female
end of the flange, making sure the internal and external sealing
rings are fitted; this will ensure the connection is properly sealed
Additional extensions and bends may be installed if required us-
ing the same method
Installing the flashing- Replace tiles with the aluminium sheet (5),
shaping it to ensure that the rainwater runs off Position the fixed
half-shell (7) on the aluminium tile and insert the intake/exhaust
pipe (6) Fit the male end (6)(smooth) of the 60/100 concentric
terminal up to the stop on the female end of the adapter(3),
making sure that the ring (4) is already fitted; this will ensure hold and joining of the elements making up the kit
Ensure that all seals are fitted and that the outer and inner pipes are installed so that all joints are perfectly
sealed A lubricant may assist in overcoming the friction of the seals Oils and conventional greases are not com-
patible with the EPDM seals used and should never be used for this purpose Talc may be used Please contact
RVR for more information
A rigid supporting clamp should be fitted on each 1 0 metre or 2 0 metre flue extension in all cases
The maximum possible overall length including the terminal is 14.4 straight and horizontal meters.
NB: If the terminal or extension pipes need shortening ensure that the inner pipe protrudes by 5mm with

Separated 80/80 flue kit
This kit enables separation of the exhaust and air intake
pipes as shown in figure 9
Combustion products are expelled from pipe (A) (in
plastic material resistant to acidic condensates) Air is
taken in through pipe (B) (also in plastic material) for
combustion
Intake pipe (B) can be installed either on the right or left
hand side of the central exhaust pipe (B) Both pipes
can be oriented in any direction
Assembly:
Install the flange (4) on the left hole of the boiler insert-
ing the seal (1), positioning it with the round protrusions
downwards in contact with the boiler flange and tighten
using the screws supplied with the kit
Remove the sealing plate from the air intake and re-
place it with flange (3)inserting seal (2) which is already
fitted on the boiler and tighten using the screws sup-
plied
Insert bends (5) with the male end (smooth) in the fe-
male end of the flanges (3&4) Fit the male end of the
intake terminal (6) up to the stop on the female end of
the bend (5), making sure that the relevant internal and
external sealing rings are fitted Fit the male of the ex-
haust pipe up to the stop on the female end of the bend,
making sure that the internal sealing ring is fitted; this
will ensure a seal and joining of the elements making up
the kit

Each component of the air inlet/flue system has a resistance factor These are given in the following tables
The resistance factor varies depending on whether the component in question conveys fresh inlet air or hot
combustion gases All boilers have a maximum resistance factor of 100 The sum of all components in the
flue system must not exceed the maximum overall resistance factor of 100

The flue terminal must be exposed to the external air and the position must allow the free passage of air
across it at all times In certain weather conditions the terminal may emit a plume of steam Avoid position-
ing the terminal where this may cause a nuisance If the terminal is fitted within 850 mm of a plastic or
painted gutter or 450 mm of painted eaves or 300 mm of a plastic car port roof, an aluminium shield at least
1 m long should be fitted to the underside of the gutter or painted surface If the terminal is fitted less than 2
m above a surface to which people have access, the terminal must be protected by a terminal guard
IMPORTANT— Failure to install flue systems correctly may lead to serious injury or death. Ensure
that:
• Only flues specifically designed for condensing boilers and provided by RVR Energy Technology
Limited are used
• The flue slopes slightly towards the boiler by between 1 and 2 degrees to ensure any condensate
flows towards the boiler Failure to do this will result in condensate dripping from the flue terminal
• The flue is adequately supported along it’s length so that it is straight and cannot be moved without
using a tool
• The flue system has no low points where condensate can collect
• All flue terminals are securely fixed
• No chemicals, detergents, solvents or liquids of any kind are used in the assembly of the flue system
Talc may be used as a lubricant where necessary
• All joints and connections are properly assembled to prevent leakage and all seals are properly
seated
• The flue is thoroughly tested for leaks after installation

The boiler can be fitted to or adjacent to a wall comprising of a combustible material without the need for a
special thermal insulation barrier
The boiler may be installed in any room or internal space, although particular attention is drawn to the re-
quirements of the current IEE Wiring Regulations Where a room sealed boiler is installed in a room con-
taining a bath or shower, it must not be possible for a person using the bath or shower to touch any electri-
cal switch or boiler control utilising mains electricity
The boiler may be installed in a cupboard or compartment, provided it is correctly designed for that pur-
pose
NB: Adequate clearances are required to allow servicing of the boiler. Please see below.

The boiler is designed for use in a sealed central heating system The system should be designed to oper-
ate with flow temperatures of up to 80°C When designing the system, the pump head, expansion vessel
size, mean radiator temperature, etc must be taken into account
The pressure losses in the system must be compatible with the boiler circulation pump See pump perform-
ance graph below:
Central Heating System
System volume - The 7 1 litre expansion vessel incorporated into the boiler is pre-charged to 1 0 bar and is
suitable for a sealed heating system with a maximum water content of 71 litres Above 71 litres, considera-
tion should be given to fitting an additional expansion vessel To check correct operation of the expansion
vessel (s) the system pressure should not be more than 2 5 bar when the system is at maximum operating
temperature
The boiler is supplied with the following components built in:-
Central Heating Pressure relief valve - complying with BS 6759 and set to operate at 3 bar The discharge
pipe must be routed clear of the boiler to a drain, so that it can be seen, but cannot cause injury to persons
or property
A Pressure gauge is included to indicate the pressure of the central heating system

The most important components of the system are shown in the diagram below
• The cold water supply for the water heating side of the system may come from a booster pump or the
cold water mains where this is permitted by the local authority
• A non-return valve must be installed on the cold feed to the boiler This prevents expanding hot wa-
ter back-feeding into the cold side of the system
• The boiler includes an automatic bypass It is not necessary to make any further provision for system
bypasses
• The boiler condensate outlet must be connected to a drain Metal pipes must not be used for this
purpose as the slightly acidic condensate will lead to rapid corrosion Plastic must be used for this
purpose
Filling the central heating system
The system design pressure (cold) should be set to 1 0 bar This pressure is equivalent to a static head of
10 2 metres of water Provision should be made to replace water lost from the system This can be by
manual or automatic means
Filling of the system must be carried out in a manner approved by the local authority Where allowed, the
system may be filled via a temporary connection as shown below or by using the integrated filling valve in
the boiler After filling, always disconnect the flexible hose of the filling loop if used and close the filling
valve in the boiler
All fittings used in the system must be able to withstand pressures up to 3 bar Drain taps (to BS 2879)
must be used to allow the system to be completely drained The heating system should be thoroughly
flushed before the boiler is connected and again after the first heating If it is necessary to add inhibitor to
the central heating system, contact RVR Ltd for guidance

Mains water pressurised unvented system are generally not permitted in Ireland A cold water storage tank
and a pressure boosting pump will normally provide a pressurised cold water supply The pressurisation
pump should provide a water pressure of between 1 and 3 bar However, all taps and mixing valves used
with the hot water system must be suitable for operating at a pressure of up to 5 5 bar The use of fittings
designed for open, low pressure systems should be avoided as this will lead to excessive water flow rates
To ensure economic use, the pipe runs between the boiler and taps should be in 15 mm copper pipe and be
as short as possible Where possible the pipe work should be insulated to reduce heat loss
Before the cold water supply pipe is connected to the boiler, it should be thoroughly flushed out to avoid the
danger of dirt or foreign matter entering the boiler
The stored water temperature is adjustable to a maximum of 55°C In hard water areas this should avoid
possible scale build-up However, if descaling is necessary contact RVR Limited for guidance
Unvented Hot Water Storage System
The installation is subject to Building Regulations and the Water Bye Laws of the Local Authority
The Victrix Zeus Superior 26/32kW boiler is supplied with all the components required for a safe and effi-
cient unvented hot water system An air cushion which is present at the top of the 54l storage vessel pro-
vides some of the expansion for the domestic hot water system The balance is provided by the additional
DHW expansion vessel installed within the boiler casing
NOTE: In the Dublin City Council area, the council requires that the minimum internal diameter of
pipes connected to the boiler DHW connections should not be less that 13mm. As 1/2” thermoplas-
tic pipe does not provide the minimum diameter, the minimum suitable thermoplastic pipe size is
3/4”
Discharge pipe - The discharge pipes from the expansion relief valves must be routed to a tundish in
1/2” (or 15 mm )pipe The discharge pipe work from both relief valves may be joined together in the same
sized pipe, providing at least 3/4” (or 22 mm) pipe work is connected downstream of the tundish
Tundish - The tundish must be positioned within 500 mm of the appliance, so that it is visible to the user
and away from electrical devices The minimum size of the discharge pipe downstream of the tundish is
given in the following table
Domestic Hot Water System
15mm (1/2”)
22mm (3/4”)
28mm (1”)
35mm (11/4”)

The discharge pipework from the tundish:-
1 Shall fall continuously through its length
2 Shall be of a heat resistant material, e g metal
3 Shall not be fitted with any valves or taps
4 Shall discharge to a safe visible position, e g onto the surface of an external wall or into a gulley
5 Shall have a minimum of 300 mm straight pipework directly from the tundish
Note: Where children may play or otherwise come into contact with discharges, a wire cage or similar
guard must be positioned to prevent contact whilst maintaining visibility
Please see the diagrams below for suggested methods of terminating the discharge pipe safely Where a
single pipe serves a number of discharges, such as in blocks of flats, the number served should be limited
to not more than 6 systems so that any installation can be traced reasonably easily The single common
discharge pipe should be at least one pipe size larger than the largest individual discharge pipe to be con-
nected If the system is installed where discharges from safety devices may not be apparent, i e in dwell-
ings occupied by blind, infirm or disabled people, consideration should be given to the installation of an
electronically operated device to warn when discharge takes place
High Level Termination
At high level, discharge onto a roof is acceptable pro-
viding the roof is capable of withstanding high tem-
peratures and there is a distance of 3 m from any
plastic guttering systems that would collect such dis-
Example:-
The example below is for a G½ temperature relief valve with a
discharge pipe (D2) having four elbows and a length of 7 m from the
tundish to the point of discharge
From Table 5:-
Maximum resistance allowed for a straight length of 22 mm copper discharge pipe (D2) from a G½ tempera-
ture relief valve is 9 m Subtract the resistance for four 22 mm elbows of 0 8 m each = 3 2 m Therefore the
maximum permitted length equates to 9 - 3 2 = 5 8 m
5 8 m is less than the actual length of 7 m therefore calculate the next largest size
Maximum resistance allowed for a straight length of 28 mm pipe (D2) from a G½ temperature relief valve
equates to 18 m
Subtract the resistance for four 28 mm elbows at 1 0 m each = 4 m
Therefore the maximum permitted length equates to 18 - 4 = 14 m
As the actual length is 7 m, a 28 mm (D2) copper pipe will be satisfactory

Fault Signals
Important: the error codes 31, 37, 38 are not shown on the CAR and Super CAR display
1. Ignition block. The boiler ignites automatically with each demand for room central heating or hot water
production If this does not occur within 10 seconds, the boiler remains in stand-by for 30 seconds, try
again and if the second attempt fails it will go into “ignition block” (ERR01) To eliminate “ignition block”
the Reset button “C” must be pressed The fault can be reset 5 times consecutively, after which the function in
inhibited for at least one hour One attempt is gained every hour for a maximum of 5 attempts By switching the
appliance on and off the 5 attempts are re-acquired On commissioning or after extended inactivity it may be
necessary to eliminate the “ignition block” If this occurs frequently, contact a qualified technician for assis-
tance
2. Safety thermostat block (over-temperature). During operation, if a fault causes excessive overheating in-
ternally, or an error occurs in the flame control section, an over-temperature block is triggered in the boiler
(ERR02) To eliminate “over-temperature block” the Reset button “C” must be pressed If this occurs frequently,
contact a qualified technician for assistance
3. Flue safety thermostat block This occurs in the case of partial internal obstruction (due to the pres-
ence of lime scale or dirt) or external blocking (combustion residues) in the condensation module To elimi-
nate the “flue safety thermostat block” the Reset button “C” must be pressed Call an authorised technician
to remove the obstructions
4. Contacts resistance block. This occurs in the case of faults to the safety thermostat (over-temperature) or
fault in the flame control The boiler does not start and a technician must be called
5. Flow probe error If the board detects an error on the system NTC flow probe (code 05) the boiler will not
start; contact a qualified technician for assistance
10. Insufficient system pressure. Water pressure inside the central heating system that is sufficient to guar-
antee the correct functioning of the boiler is not detected Check on the boiler manometer (1) that the system
pressure is between 1 - 1 2 bar and restore the correct pressure if necessary
12. Cylinder probe fault If the board detects a fault on the cylinder probe, the boiler cannot produce domestic
hot water A qualified technician must be called for assistance
15. Configuration error. If the board detects an error on the electric wiring on first power supply, the
boiler will not start If normal conditions are restored the boiler restarts without having to be reset The defect

could be due to a fault in the flue flow meter detected after restoring the electric mains voltage If this per-
sists, contact a qualified technician for assistance
16. Fan fault. This occurs if the fan has a mechanical or electrical fault To eliminate the “fan
fault” the Reset button “C” must be pressed If this fault persists, contact a qualified technician for assis-
tance
20. Parasite flame block. This occurs in case of a leak on the detection circuit or fault in the flame control
unit The boiler can be reset in order to allow a new ignition attempt If the boiler does not start, contact a
qualified technician for assistance
23. Return probe error. In this condition the boiler does not correctly control the pump if set as “Auto”
The boiler continues functioning but to eliminate the error, contact a qualified technician for assistance
24. Push button control panel fault. This occurs when the circuit board detects a fault on the
push button control panel If normal conditions are restored the boiler restarts without having to
be reset If this fault persists, contact a qualified technician for assistance
27. Insufficient circulation. This occurs if there is overheating in the boiler due to insufficient water
circulating in the primary circuit; the causes can be:
- low circulation; check that no interception devices are closed on the central heating circuit and that
the system is free of air (deaerated);
- circulating pump blocked; free the circulating pump
If this occurs frequently, contact a qualified technician for assistance
31. Loss of remote control communication. This occurs in the case of connection to a remote
control that is not compatible or if there is a loss of communication between the boiler and CAR remote con-
trol or Super CAR remote control Try the connection procedure again by turning the boiler off and then
back on again If the Remote Control is still not detected on re-starting the boiler will switch to local
operating mode, i e using the controls on the boiler itself In this case the boiler cannot activate
the “CH ON” function To make the boiler function in “CH ON” mode, activate the “P33” function pre-
sent inside the “M3” menu If this occurs frequently, contact a qualified technician for assistance
37. Low power supply voltage This occurs when the power supply voltage is lower than the allowed limits
for the correct functioning of the boiler If normal conditions are restored, the boiler restarts without having
to be reset If this occurs frequently, contact a qualified technician for assistance
38. Loss of flame signal This occurs when the boiler is ignited correctly and the burner flame switches off
unexpectedly; a new attempt at ignition is performed and if normal conditions are restored, the boiler
does not have to be reset (this error can be checked in the list of errors P19 present in the “M1” menu) If
this incident occurs frequently, contact a qualified technician for assistance
Other maintenance operations :
Lack of water in boiler.
Not enough water pressure detected in the heating circuit to guarantee correct boiler operation Make sure
that the pressure in the system is between 1 and 1 2 bar N B Close the valve on completion If pressure
valves reach around 3 bar the safety valve may be activated In this case contact a professional technician
for assistance In the event of frequent pressure drops, contact qualified personnel for assistance to elimi-
nate system leakage
Syste flow NTC sensor fault.
If the unit detects a problem with the system delivery NTC sensor, the boiler will not start; call a qualified
technician
