should be followed including
1. INTRODUCTION
Page 3 of 12
The KINGSPAN TRIBUNE Unvented tank is made from Duplex Stainless Steel for excellent corrosion resistance. KINGSPAN
TRIBUNE has a strong rust-proofed steel case and is highly insulated with environmentally friendly foam.
2. INSTALLATION
WARNING
The KINGSPAN TRIBUNE is a pressurised unit. Care must be taken to install the relevant safety valves and expansion
equipment, as specied in these instructions, to ensure the safe use of this unit. Failure to do so may result in serious injury
or death.
2.1 UNPACKING AND POSITIONING THE UNIT
The KINGSPAN TRIBUNE tank should be stored in its original packaging in an upright position in an area free from excessive
damp.
Carefully unpack the unit and check that no delivery damage is present. DO NOT USE the unit if there is any sign of damage.
Site the tank on vertically on a at base capable of supporting the weight of the tank when full. If the tank is to be located in
an area where damage from water leaks would cause damage to the surrounding area or substructure a drained catch pan
should be installed to remove the water to a water drain. The pan should have a minimum diameter 2” greater than the tank and
a wall height maximum of 2”. The pan should be connected to drain by a ¾” bore drain. Consult a certied plumber for more
information
The KINGSPAN TRIBUNE should be located near to a drain to allow the drainage of water during maintenance and as an outlet
for the safety equipment located on the unit.
The KINGSPAN TRIBUNE tank can supply outlets above it or at some distance from it. Site the unit to minimise “dead leg”
distances, especially to the point of most frequent use.
Outlets above the KINGSPAN TRIBUNE will reduce the outlet pressure available by 1.45psi for every 3’ of height difference.
The unit should be protected from frost. Particular care is needed if placing in a garage or outbuilding. All exposed pipework
should be insulated. KINGSPAN TRIBUNE must be installed VERTICALLY on a at base capable of supporting the weight of
the tank when full.
Access for maintenance of the valves should be considered. The electric elements are 16” long element and care should be
taken to ensure that they can be withdrawn for servicing if required. The discharge pipework from the safety valves should fall
continuously and terminate safely.
The Kingspan Tribune is designed as a domestic hot water tank. Only persons who have the proper qualications to design
and install heating systems should install this unit. Any applications or unauthorized alterations to the tank may be dangerous
and will invalidate warranty.
2.2 PLUMBING CONNECTIONS
KINGSPAN TRIBUNE tanks can be supplied in a single or dual coil conguration. The coils are single wall coils, this allows a variety
of heat sources to be used. In the single coil conguration this can be connected to a boiler or solar circuit. Twin coil tanks the lower
coil is connected to a solar circuit and the top coil to a boiler system. Figure 1 shows a schematic of the tank conguration.
Page 4 of 12
Figure.1 Single and Twin coil congurations
2.2.1 Cold Main Pipework
Please refer to local code for cold mains pipe work installation.
Run the cold main through the building to the place where the KINGSPAN TRIBUNE is to be installed. Take care not to run
the cold pipe near hot water or heating pipe work so that the heat pick-up is minimized. Identify the cold water supply pipe and
t an isolating valve (not supplied). A quarter turn full bore valve is ideal as it does not restrict the ow as much. Do not use
“screwdriver slot” or similar valves.
Thermal Expansion:
Determine if a check valve exists in the cold inlet water line (These may be incorporated in a pressure reducing valve, water
softener, water meter or as a separate back ow preventer).
If a check valve exists then this will cause a closed water system meaning that thermal expansion may cause a pressure build
up within your hot water tank. In such a case an expansion tank must be tted to allow for any excess pressure caused by
thermal expansion. Please see gure.2 for reference.
Water pressure:
If the incoming water pressure is over 80 PSI a pressure reducing valve (Water pressure regulator) must be tted. This is to be
located on the inlet water line before the tank so that the inlet pressure to the tank does not exceed 80 PSI.
Make the connection to the cold feed of the tank.
Select a suitable position for the expansion tank. Mount it to the wall. Use the exible hose or pipe to connect to the expansion
relief valve.

2.2.1 COLD MAIN PIPEWORK
Balanced supply allows the
TRIBUNE to provide balanced
pressure to the remainder of the
dwelling. Mixing device should
be used to prevent scalding and
control temperature of water
from the outlet taps.
Page 6 of 12
2.2.3.1 SOLAR CONNECTIONS: SINGLE COIL
The ow and return from the solar heat source are to be connected to the lower coil. Either primary coil connection may be
utilised as the ow or return. The solar sensor, supplied as part of the solar controls, is inserted into the sensor well above the
solar coil and is held in place with the black sensor well retaining bung provided.
2.2.3.2 SOLAR CONNECTIONS: TWIN COIL
In a solar thermal system the lower coil is connected to the solar heat source. Either primary coil connection may be utilized as
the supply or return. The solar tank sensor, supplied as part of the solar controls, inserts into the sensor well above the solar
coil.
The upper boiler coil will be connected to the boiler as per the manufacturers’ instructions. Ideally boiler thermostat should be
located in a sensor well above the coil position.
2.2.4 HOT WATER PIPEWORK
Run the rst part of the hot water distribution pipework in ¾” . This can be reduced to the appropriate size for the type of faucet
etc. Your aim should be to reduce the volume of the hot draw-off pipework to a practical minimum so that the time taken for
the hot water is as quick as possible. Do not use monobloc mixer faucet or showers if the balanced cold connection is not
provided. Outlets of this type can back pressurize the unit and result in discharge.
The use and installation of an ASSE approved thermostatic mixing valve is required.
The suggested location for this valve may be seen in section 2.2 Figure 2.
2.2.5 TEMPERATURE AND PRESSURE RELIEF VALVE
The hot water tank must be installed with an appropriate temperature and pressure relief valve. The hot water tank has a
¾”NPT female connection to accommodate this apparatus in the top of the tank.
CAUTION: To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure
protective equipment required by local codes but no less than a combination pressure valve certied as meeting the
requirements for Relief Valves and Automatic Gas Shutoff devices for Hot Water Supply Systems ANSI Z21.22.
The T&P valve must be connected to a discharge pipe. This pipe must:
• Terminate a maximum 6” above a oor drain. In the rare event of a discharge the water will be very hot and may be
combination of water and steam, at pressure. Care must be taken to safely route the discharge pipe safely to drain.
• Be no smaller than ¾” diameter and must not be reduced in size.
• No other valve can be placed on the discharge line between the T&P valve and the discharge exit.
• The pipe must be capable of withstanding 250˚F.
• The pipe must be compiled of straight runs, direct to drain, to allow complete drainage of the valve and pipe assembly.
• The relief valve connections should not be used for any other purpose.
2.2.2 CONNECTING TO THE TANK
All of the water carrying pipe connections on the tank are ¾” NPT male. Suitable jointing compound that is suitable for potable
water and hot water should be used to provide a watertight seal.
2.2.3 COIL CONNECTIONS
The coil connections to the boiler or solar circuit are ¾” NPT male. Ensure good connections. Use commercially accepted
water inhibitors as stated by the manufacturer of the boiler or renewable energy system.
WARNING
The expansion tank is an important safety feature of the tank installation. It must be installed and properly sized. Refer to
Table.2 for Kingspan supplied sizes.

Figure.3 Immersion wiring, a) layout of immersion wiring terminals, b) wiring diagram.
Only immersion heaters with a thermal over temperature saefty cut out may be used. The immersion heaters have a 1-1/4”
NPT thread. Thread will have to be sealed with appropriate compound/tape. They are rated at 4.5 kW at 240 V and are of
a low noise Incoloy construction. The thermostat should be set to limit the temperature to a maximum of 185˚F (85˚C). It is
recommended that that the water temperature is set for the lowest temperature that satises your hot water needs. Setting
the temperature to 120˚F will reduce the risk of scalds. Please order the correct replacement via Kingspan Solar; tting non-
approved heating elements may affect your warranty.
If no immersion heater is to be installed, it is recommended that a brass 1-1/4” plug be used.
The cable must be copper 10AWG heat resistant compliant with the National Electrical Code, ANSI/NFPA 70. The heaters
must be connected to a dedicated branch circuit with the relevant protection devices. The cable must be connected to a eld
wiring terminal that is rated for the immersion heater current load. The unit must be grounded to a properly installed ground
circuit using an appropriate eld terminal.
Check the immersion heaters are 240V and rated at 4500W this should be stated on the case.
Figure 3 shows the layout and wiring schematic of the heating element. To access the wiring terminals, rstly, remove the
temperature dial by gently pulling of the dial completely off, then loosen the three retaining screws on the edge of the cover
and slide the red cover off the unit.
The terminals are set up for single phase 240V series operation.
The 1L1 wire is white and the 1L2 wire is black. The green stud, refer to Figure 3 a) shows the grounding connections. Use
correct wire connections and ensure a proper gland/grommet is used to exit the immersion heater casing
WARNING
The tank must be full of water before any power is switched on. Heating elements will be damaged if powered in air.
2.3 IMMERSION HEATERS
WARNING: Use a qualied electrician to install the KINGSPAN TRIBUNE hot water tank. The tank must be electrically
wired in accordance with these instructions and the relevant local codes. If local codes do not apply consult the National
Electrical Code.
HAZARD OF ELECTRIC SHOCK! Any installation involving electric heaters must be grounded to earth to eliminate shock
hazard.
3.0 COMMISIONING
Check that the pressure in the expansion tank is the same as the setting of the pressure reducing valve. The valve is of the car
tire (Schrader) type. Check all the connections for tightness including any factory made connections such as the immersion
heater and the temperature and pressure relief valve. Before lling, open the hot faucet furthest away from the KINGSPAN
TRIBUNE to let air out. Open the cold main isolation valve and allow the unit to ll. When water ows from the faucet allow it to
run for a short while to ush through any dirt, swarf or ux residue. Close the faucet and open every other hot faucet in turn to
purge all remaining air.
3.1 FILLING
If the tank is to be heated by an indirect boiler, consult the boiler manufacturers’ commissioning instructions and ll the primary
circuit accordingly. Two port valves and tank thermostats may need to be used to control input into the KINGSPAN TRIBUNE
unit.
3.2 INDIRECT UNITS
During heat-up there should have been no sign of water coming from either the expansion relief valve or the temperature/
pressure relief valve. Now hold both of these safety valves fully open, allowing as much water as possible to ow through the
discharge line. Check that your discharge pipe work is free from debris and is carrying the water away to waste efciently.
Release the valves and check that they reseat properly.
3.3 SAFETY VALVE CHECKS
Page 8 of 12
4.0 MAINTENANCE
Servicing should only be carried out by competent installers and any spare parts used must be purchased from Kingspan
Solar. NEVER bypass any safety devices or operate the unit without them being fully operational.
The KINGSPAN TRIBUNE is tted with a ½” NPT drain tting at the base of the tank. An appropriate draining faucet should be
installed that can not be accidentally opened.
Isolate from the electrical supply to prevent the immersion heaters burning out. Isolate the unit from the cold mains.
WARNING: WATER DRAINED OFF MAY BE VERY HOT!
4.1 DRAINING
TRIBUNE HE requires an annual service in order to ensure safe working and optimum performance. It is essential that the
following checks are performed by a competent installer on an annual basis. Commonly this is done at the same time as the
annual boiler or solar system service.
1) Lift the lever on the expansion relief valve on the inlet control set and allow water to ow for 5 seconds. Release and make
sure it resets correctly. Repeat with the pressure / temperature relief valve. In both cases check that the discharge pipe
work is carrying the water away adequately. If not, check for blockages etc. and clear.
WARNING: THE WATER DISCHARGED MAY BE VERY HOT!
2) Check that any immersion heaters tted are working correctly and that they are controlling the water at a temperature
between 60˚F no more than 185˚F
3) Check the pressure in the expansion tank is charged to 44psi. Turn off the water supply to the unit and open a hot
faucet rst. The air valve on expansion tank is a Schrader (car tire) type. Air or CO2 may be used to charge the expansion
tank.
4) If tted, Unscrew the head on the inlet control set and clean the mesh lter within.
YOUR WARRANTY MAY BE VOID WITHOUT PROOF OF ANNUAL SERVICING
