Victrix Zeus Superior 26/32kW Instructions
The Victrix Zeus Superior 26/32kW boilers are condensing wall hung, room sealed combination boilers incorporating a 54 litre stainless steel unvented hot water storage cylinder. This boiler has the highest efficiency possible for a gas boiler, i.e. 4 stars (****) in conformity with European Directive 92/42 EEC.
The boiler, providing both central heating and domestic hot water supply, is designed for use with a fully
pumped, sealed and pressurised heating system using Natural Gas or LPG. The boiler is supplied for use
with one of these gas types and must be converted before it can be used on another gas. A boiler equipped
for natural gas must not be used on LPG or vice versa.
The boiler is supplied with a pump, diverter valve, automatic bypass, pressure relief valve, expansion vessel
and pressure gauge fully assembled and tested.
As supplied, the boiler will automatically modulate to provide central heating outputs between 4.7 and
20.0kW for the 26kW model and 6.9 to 32kW for the 32kW model). The maximum output available for domestic hot water is 26.9 kW for the 26kW model and 33kW for the 32kW model and the boiler provides hot
water at temperatures of up to 60°C.

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 polarity of the supply must be correct as
otherwise the boiler will not operate
properly.
There must only be one common isolator, 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 outlet (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 voltages, 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 conditions. This results in lower energy usage and enhanced comfort.
WARNING ! - 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 inserting the seal (1) with the round protrusions facing downwards in contact 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), 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 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 condensate 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 system 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 inserting the seal (1) with the round protrusions facing downwards
in contact with boiler flange and tighten using the screws supplied 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 using 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 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 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 inserting 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 replace it with flange (3)inserting seal (2) which is already
fitted on the boiler and tighten using the screws supplied.
Insert bends (5) with the male end (smooth) in the female 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 exhaust 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.
Separated Flue Systems
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 condensate 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 system 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 without any bends is 36 straight, horizontal meters or 41
straight, vertical meters regardless of whether they are used in intake or exhaust. See the section
on extended flue design for more information.
