1.3 GENERAL DESCRIPTION & BASIC OPERATION
The TVS 300 is a transportable indirect oil red warm air heating appliance. The design includes a high efciency fully welded
stainless steel four pass drum and tube combustion chamber and heat exchanger protected by various safety and operating
interlocks. The other main components within the TVS 300 include: a Riello RL 44 two stage pressure jet oil burner, a high
efciency two speed fan and motor assembly, and a control panel with safety interlocks and visible status lamps.
Burner safety devices are compliant with the latest European norms, and the combustion chamber and heat exchanger are
protected by an overheat safety thermostat. A cartridge heater provides frost protection within the control panel.
Only the following fuel types should be used with the Alpha range: BS2869:2010 Class D Gas Oil with blends of no more than
10 percent Bio-Diesel (EN14214) added.
Caution:
If other fuel types are intended to be used (e.g. Kerosene or Bio-Diesel) reference should be made to El-Bjorn AB
(or their agents), and also to the relevant sections of this manual prior to use.
The TVS 300 requires the ue to be connected before the burner is red. If the appliance is to be used externally the ue should
be terminated with a suitable weather-proof cowl, and the position of the ue terminal must comply with the appropriate
regulations, and should not be any closer than 3m from any other nearby taller building or structure. If the TVS 300 is to be used
within an existing building or plant room, provision must be made for providing an adequate supply of combustion air and for the
safe exit and removal of ue gases.

4
Phase sensitivity
The TVS 300 requires a 400 Volt 3 Phase 50 Hz electrical supply. The control panel isolator also serves as a phase rotation/selec-
tion switch in the event of incompatibility between the site supply and the appliance. The control panel also has a phase warning
lamp in the event of incompatibility.
Ventilation – without heating
The TVS 300 can be used without its heating capabilities as a ventilation fan to add “make up” air to an enclosed area from outside
via ducting, or from inside via an external duct. It can also be used as an air extract fan, to extract air from within an enclosed space.
Again, this can be done via ducting with the TVS 300 situated within the area our outside the area.
Heating
The TVS 300 has a high efciency combustion chamber and heat exchanger, and can be operated to provide clean warm air to an
area, either as a free blowing unit, or with ducting connected to either, or both, the inlet and the discharge spigots. The heating
circuit has two heat settings offering 300kW (high) or 175kW (low) of heating. The control panel on the TVS 300 has a connection
for an external room thermostat or time clock to control the demand for heating. The TVS 300 is supplied with an electrical link in
place within the external thermostat socket on the control panel, this provides a constant demand for heat, and should be removed
and replaced with an external thermostat or time clock if these are required. It should be noted that the burner will not be enabled
unless there is a demand for heat (or the link is present). At the end of a heating cycle the appliance must be allowed cool down so
as to dissipate residual heat from the combustion chamber and heat exchanger, and the main electric supply must not be turned off
until the fan over run cycle has been completed and the appliance has cooled to a safe level.
Burner
The TVS 300 is tted with a fully automatic Riello RL 44 oil red burner, which includes a sequential control box, and all necessary
safety interlocks. The burner has high re and low re settings, the ring rates of which have been factory set during pre-delivery
testing and setting. Combustion settings and ue gas analysis details are contained within Section XXX of this manual.
Operating devices
The controls on the TVS 300 offer exibility and safety, combined with simplicity. Status lamps on the control panel give an instant
status report. Within Section 1.10 are electrical drawings, these include diagram explaining the functions of the control panel and
the operating and safety thermostats. Overheat and re-cycling thermostats are tted to the TVS 300. A temporary restriction to
airow (excess resistance) can operate the re-cycling thermostat which will reduce the burner to low re whilst the main supply fan
(when set on “High”) will continue on full load air volume. In the case of an overheat alarm occurring, the burner will be disabled
and a manual reset will be required on the main control panel.
Note
A loss or interruption of electrical power (greater than 15 seconds) will also result in an overheat alarm being registered, and will
require a manual re-set.
Basic start and shut down procedures
This section is intended for site operatives and the procedure must only be used after full and satisfactory commissioning has been
completed by qualied and competent personnel on site. The procedure assumes the following:
• The ue has been installed and checked
• Oil supply has been connected, bled, and checked
• Electrical supply has been tested and is connected, and the isolator/phase selector in the “on” position
• Any ducting has been secured and tested
• Any external thermostat or time clock has been connected and tested
Warning
Do not proceed with the following sequence unless commissioning has been satisfactorily completed.
• Check main electrical isolator/phase selector is in the correct on position
• Check room thermostat or timer is calling for heat
• Select “Heat” on the heat/vent/off selector
The burner will go through the ignition sequence and start to heat the combustion chamber and heat exchanger and usually within
1 – 2 minutes will activate the fan thermostat which will pull in the main supply fan. Warm air will be discharged from the discharge
spigot.
The TVS 300 will continue to operate whilst being controlled by the external thermostat or time clock. The status of the heater
will continue to be monitored by the operating thermostats and overheat safety thermostat, which will if necessary over ride the
external thermostat or time clock.
At the end of the desired heating cycle the control panel selector switch for Heat/Vent/Off should be turned to the “off ”
position, and the fan over-run facility should be allowed to continue so as to dissipate residual heat within the combustion chamber
and heat exchanger.

Warning
The power supply must remain connected and the main Isolator/Phase Sector switch remain in an “on” position so to allow for
fan over run to continue for at least 5 – 10 minutes.
1.4 TRANSPORTATION, LIFTING, & POSITIONING
The TVS 300 must be secured and transported on an appropriate at bed vehicle (or similar) in the normal upright position so
it does not overhang or project from the vehicle. Special care should be taken in respect of the centre of gravity and the uneven
weight distribution, and the ue must be removed when the TVS 300 is being lifted or transported.
The TVS 300 must be positioned and installed on a level surface capable of supporting the weight of the TVS 300 and any
ancillary equipment. The location must also provide adequate clearance for the oil supply and electrical supply to be connected and
safely maintained, whilst also providing good and safe working access to the TVS 300 and any other ancillary plant or equipment.
Care should be taken to ensure the TVS 300 is located in a position where it, and any ancillary plant, will not be damaged by other
site trafc in the vicinity, and if necessary adequate protective safety fencing should be erected to protect the TVS 300.
Warning
Lifting loading/unloading and positioning by fork lift truck
Lifting, loading, unloading, and positioning of the TVS 300 must be carried out only by competent persons. The TVS 300 has been
designed to be lifted and positioned by fork lift truck and the integral fork lift truck pockets must only be used for this. The type of
fork lift truck must also be compatible and suitable for carrying out the operation of lifting and positioning. The TVS 300 can have
an uneven weight distribution and a relatively high centre of gravity.
Net weight = 1600 Kg
Warning
Lifting loading/unloading and positioning by crane
Lifting, loading, unloading, and positioning of the TVS 300 must be carried out only by competent persons. The TVS 300 has
been designed to be lifted and positioned by crane and the integral lifting eyes positioned at high level at each corner must only be
used for this. The type of crane must also be compatible and suitable for carrying out the operation of lifting and positioning.
The TVS 300 can have an uneven weight distribution and a relatively high centre of gravity.
1.5 SITE INSTALLATION
Warning
Special risk sites
The location and positioning must comply with all the relevant local and national laws, standards, and guidance, especially in respect
of re regulations and insurance criteria. Additional care should be taken and checks should also be made if the TVS 300 is inten-
ded for use within a special risk area, such as, where petrol engine vehicles are parked or stored, where cellulose spraying occurs, or
where woodworking machinery is operated. The TVS 300 must not be operated within hazardous areas and should not be operated
where there are high concentrations of chlorides, uorides, salts, or other aggressive or volatile chemicals or compounds present.
Operators should be familiar with any special requirements associated with the operation of plant and equipment on high risk or
hazardous sites, such as petro chemical plants, oil storage depots, and reneries.
The manufacturer of the TVS 300 will not accept liability for any claims arising from or associated with the use of the TVS 300, or
ancillary plant, on unsuitable, high risk, or hazardous sites. The responsibility for the operation of the TVS 300 on all sites remains
with the operator of the equipment.
Flue Installation
Warning
Flue arrangements must comply with all the appropriate local and national regulations.
The ue must be connected securely to the TVS 300 and must project at least 600mm above the roof of the TVS 300. On external
applications the ue must be adequately sealed and secured and be nished with a weatherproof terminal to prevent ingress of rain.
When positioning the TVS 300 care should be taken to ensure the ue outlet is sited more than 3m from any other higher building
or structure, to prevent the effects of down-draughts, and to prevent the ue products from being drawn into a building through
windows, doors, openings, or ventilation systems.
5

On internal applications the ue must be discharged to the outside of the building via a satisfactory ue. Horizontal ue runs
should be avoided. Where the ue length exceeds 5 m, provision must be made for condensate removal from the ue so as to
prevent condensate draining from the ue into the heat exchanger.
Combustion air
When installed within an internal application an adequate air supply must be provided to allow for combustion. Guidance on the
combustion air requirement and how this may be achieved is available from El-Bjorn AB.
Fuel Supply
Warning
The location and position of the fuel tank and fuel supply pipe work must comply with the appropriate local, national, and
European laws and regulations. Care should be taken to prevent environmental damage associated with any leaks or spills of fuel.
The TVS 300 has a Riello RL44 Burner tted and has been factory tested and set to run on 35 Second Gas Oil. If other fuel
types are to be used reference should be made to El-Bjorn AB and the appropriate section of the Riello burner manual contained
herewith. Integral to the fuel system on the TVS 300 is a tiger loop and fusible link with a re safety valve.
In order to prevent problems associated with cold weather it is important the fuel within the fuel tank and the pipe work does
not fall below the Cold Filter Plugging Point (CFPP). In the UK the critical temperatures for Class D 35 Second Gas Oil are -4°C
(Summer Grade) and -12°C (Winter Grade). In Sweden the critical temperatures are -3°C (E10 - Summer Grade) and -23°C
(E32 - winter grade).
The fuel pump inlet pressure must not be greater than 0.4 Bar, above this pressure gas can be liberated from the oil and can cause
burner lock out and operating problems.
Bio-Fuels
Caution
The use of new Bio-Fuels is not recommended (for example B7 or B10) and these fuels should only be used when the
concentration is less than 10 percent. The seals within the fuel supply line and burner components, may not have not been
specied with seals compatible for use with new Bio-Fuels at concentrations greater than 10 percent.
Kerosene
Kerosene (28 Second Oil – Class C2) can be used, however, the burner must be set up according to the relevant section of the
Riello operating instructions.
Electrical supply
Warning
The TVS 300 must be isolated from the electric supply before any installation or maintenance work is carried out on the machine.
A 400 Volt 3 Phase 50 Hz supply is required for the TVS 300. The supply must comply with any site restrictions as well as the
appropriate local and national regulations. Connection to the appliance must be made via a suitably rated 32 Amp plug and cable
assembly, and should only be carried out by competent persons. Care should be taken to ensure the cable cannot be damaged by
other site trafc or machinery.
Caution
Wiring external to the appliance must be installed in accordance with any local, national, and European regulations, as well as
meeting the appropriate requirements of IEE regulations. The means of connection to the main electrical supply must allow for
complete electrical isolation of the appliance, additionally, in the case of the TVS 300, the supply should only be used to serve the
appliance itself and must not supply other plant or equipment.
Caution
The main electrical supply must not be switched off or disconnected as a method for stopping or shutting down the appliance, the
exception to this is in the event of an emergency. Turning off the electric supply to the TVS 300 during, or at the end of a heating
cycle, will prevent the supply fan from operating to dissipate residual heat and can cause overheating and damage to the machine.
Overheating will activate the overheat thermostat which will automatically disable the burner and require manually re-setting.
Air ow
The TVS 300 can be used as a fully free blowing appliance (without ducts), partially free blowing (with either discharge or re-
circulation ducts connected), or fully ducted (with both discharge and re-circulation ducts connected). The TVS 300 has additional
fresh air inlets so as to ensure fresh air is added to re-circulated air. The proportion of fresh air to re-circulated air will be deter-
mined by the resistance within the system. A high system resistance will mean a greater amount of fresh air will be drawn into the
system.
6

The TVS 300 is supplied with 1 x 800mm diameter discharge spigot, and 1 x 800mm diameter inlet/re-circulation spigot.
These spigots can have transformation pieces tted so as to provide 2 x 510mm (discharge) and 2 x 510 (inlet/re-circulation
connections.
Any ducting which is connected must be of an approved type, and the rst 3m of discharge ducting must be validated for use on
temperatures to 150oC, any recirculation ducting must have sufcient rigidity to operate whiles under suction.
Warning
The maximum system resistance the machine will tolerate is 500 Pa. Ducting must therefore be congured so as to have less than
500 Pa system resistance, and the duct lengths should be as short as possible and have as few bends as possible. High system
resistance will result in frequent operation of the re-cycling thermostats, and excessive system resistance will result in frequent
overheat thermostat alarms.
1.6 PRE-COMMISSIONING

1.8 SERVICING
Warning
Servicing must be carried out on a regular basis, the maximum interval between services being 1 year. It is a requirement that only
suitably qualied and competent persons are allowed to undertake servicing. Before any maintenance or servicing work is
carried out the heater must be shut down and allowed to cool, and have the oil and electric supplies to it turned off at the
supply valve and isolator respectively.
Caution
Certain component parts are factory sealed and are designed so as to be tamper proof. Usually such items do not require servicing,
and therefore should not be tampered with. Failure to comply with this can invalidate any warranty, and can also lead to premature
failure. The following parts fall within this category: thermostats, fan and motor.
Reference should be made to the separate information covering the operational details of the burner .
Caution
Only approved spare/replacement parts can be tted, failure to comply with this can compromise the safe and efcient running of
the heater, and can also invalidate the warranty.

Servicing Procedure – Major Component Parts
Flue
A visual inspection should be carried out to ensure that the ue remains adequately sealed and supported, both on the outside as
well as the inside of the appliance. The presence of the ue terminal should be checked.
Main Fan Motor
Remove the side access panel. Dust and other foreign matter should be cleaned by blowing over with compressed air and through
the use of a soft bristle brush and cloth. Solvent wipes may be used to remove heavy soiling from the motor casing. Traces of
surplus lubricants spreading from the bearings should also be cleaned away. Where motors are tted with grease nipples bearings
should be lubricated with the correct grade of lubricant. Motors which do not have grease nipples feature sealed bearings which
are lubricated during manufacture for their life. The electrical connections should be checked as follows. The cover to the terminal
box should be removed by undoing the screws which secure it and the terminals and wiring should be checked for signs of
corrosion, tightness, and to ensure that there are no stray strands which could form a short circuit. Clean, tighten, and replace as
necessary, and replace cover and secure.
Main Fan
Remove dust and other foreign matter by blowing off with compressed air or through the use of a soft bristle brush. Check that
the bearings do not show signs of excessive wear. It should be noted that these bearings do not require lubricating.
Pulleys
Check pulleys for alignment using a straight edge, if necessary reposition either or both of the pulleys and the fan motor.
Check for excessive wear within the root and sides of the grooves, and check for any other signs of wear or damage, if necessary
replace the pulley.
Fan Belts
Check belts for signs of wear. Frayed or split belts must be replaced using belts with a common batch code. Belt tension must be
checked, and if on multiple belt units it is found that one belt contains more slack than its accompanying belts, then all the belts on
the unit must be replaced, again using a common batch code.
Note
The maximum displacement at the mid-point of the top edge of the belt must not be greater than 16mm per metre of span, when
a force of 3kg is applied in a plane perpendicular to the belt.
10

Electrical Supply & Controls
All connections must be checked to ensure that they are secure, and free from corrosion. Terminals and connections should also
be checked to ensure that no stray strands are bridging terminals. Electrical continuity should also be checked.
Oil Supply
The oil supply pipe work and ttings should be inspected to ensure that they are free from corrosion, and to ensure that where
brackets have been tted these remain secure and offer adequate support. The oil lter should be replaced with a new one, and the
system should be checked for leaks.
Note
Any waste oil or sludge must be disposed of correctly. Never dispose of it by dumping or tipping it down drains or into water cour-
ses where ground water can become polluted and environmental damage caused.
Burner
Service requirements for the burner tted to the heater are covered in the separate manual prepared by the burner manufacturer
and contained within this manual.
