in the Winter position. g) Check that the overheat reset button has not operated.

2. Lighting the Air Heater

2.1 Gas-fired Heaters

1. Switch on the electrical supply at the isolator and the burner start-up sequence will commence. The burner air fan will run and after a pre purge period of approximately 30 seconds the ignition spark will be generated.

CP 100 - 300 The main gas valves will open and the main burner will be

established CP 400 - 2000 The start gas valves will be opened and a start gas flame

established. When a start gas flame is established the main gas valves will be energized and the start gas flame will expand to main flame.

NOTE: If the main burner or a start gas flame fails to establish the burner will go to lockout and the lockout indicator / reset button on the burner control box will be illuminated. To restart the burner push the lockout reset button. Additional, more easily accessible, controls may be fitted that mimic the lockout indicator and reset button functions.

If the unit will not light after four or five attempts then shut down the unit and call in a service engineer.

2.2 Oil-fired Heaters

NOTE: If it is not possible to light the heater after 2/3 attempts contact the local service company.

The main burner will then start. NOTE: If the burner fails to light it will go to lockout and the

lockout indicator / reset button on the burner control box will be illuminated. To restart the burner push the lockout reset button.

3. To Shut Down the Air Heater

3.1 For Short Periods: Turn the room thermostat to the OFF or lowest setting.

3.2 For Long Periods: Turn the room thermostat to the OFF or lowest setting. Wait approximately 4-5 minutes for the main air fan of the heater to stop running and the turn off the gas or oil supplies and electric supplies to the heater.

4. Description of Operation

Important: All heaters must be controlled by the fitted external controls and not by use of the main switch in the electrical supply to the heater.

The burner start up sequence will commence when the controls e.g. Timeclock, room thermostat etc. call for heat. The burner air fan will run and after a pre purge period the burner will light.

Approximately 2/3 minutes after the burner lights the heater fan

Users Instructions

will automatically start. When the external controls are satisfied the burner will be turned off and approximately 4/5 minutes later the heater fan will automatically stop.

4.1 Summer / Winter Modes

Certain types of external controls will provide for two modes of operation i.e.

Summer: The heater fan alone will run at the dictate of the

external controls to provide air movement.

Winter: The heater will operate normally.

5. Fan and Limit Control

The fan and limit controls are mounted towards the top of the air heater upper front panel.

5.1 CP 100 - 1000

i) Main Air Fan MAN / Auto When the white button (Refer to Figure below) is pushed in

the fan will run continuously i.e not controlled by any external controls e.g. Timeclock. When the white button is pulled out the fan will start and stop automatically in conjunction with the burner. See Section 4.

ii) Limit Thermostat Reset In the event of a fault that causes the temperature of the air

leaving the air heater to rise significantly e.g. Blocked air inlets, the limit thermostat will operate to shut down the burner. Remove the cause of the fault, wait 10 minutes and then reset the thermostat by pushing the red reset button (Refer to Figure below) .If the limit thermostat continues to operate turn off the air heater and call a service engineer.

Those appliances having a gross input rating not exceeding 60kW viz. CPG100 - 150 inclusive and installed so as to take their combustion air from within the building must be installed in accordance with the relevant recommendations of the following document. BS 5440 Flues and Air Supply for gas appliances of rated input not exceeding 60kW (1st and 2nd family gases), Part 2 - Air Supply Reference should also be made to BS 5864. Code of Practice for installation of gas-fired ductedair heaters of rated input not exceeding 60kW.

3.1.2 Service Pipes

The local gas undertaking should be consulted at the installation planning stage in order to establish the availability of an adequate supply of gas. An existing service pipe must not be used without prior consultation with the local gas undertaking.

3.1.3 Meters

A gas meter is connected to the service pipe by the local gas undertaking or a local gas undertaking contractor. An existing meter should be checked, preferably by the gas undertaking, to ensure that the meter is adequate to deal with the total rate of gas supply required.

3.1.4. Installation Pipes

Installation pipes should be fitted in accordance with IGE/UP/2. Pipework from the meter to the air heater must be of adequate size. Do not use pipes of a smaller size than the inlet gas connection of the heater. The complete installation must be tested for soundness as described in the above Code.

3.1.5. Boosted Supplies

Where it is necessary to employ a gas pressure booster the controls must include a low pressure cut off switch at the booster inlet. The local gas undertaking must be consulted before a gas pressure booster is fitted.

3.2 Oil Fired Heaters

3.2.1 Related Documents

The installation of the air heater(s) must be in accordance with the rules in force and the relevant requirements of the Building Regulations and the I.E.E. Regulations for Electrical Installations.

Fig 1 Minimum clearance distances

4. Installation of Air Heater(s)

4.1 General

Before installation, check that the local distribution conditions, fuel specification, and adjustment of the appliance (see data plate) are compatible.

Important:

Copper Sulphide / Black Dust

In some areas of the UK, particularly Northern Ireland, problems have been experienced with copper sulphide (more commonly referred to as Black Dust) forming on the inner surfaces of copper gas supply pipework. This dust can enter the gas stream and may lead to blockages of valves, filters and injectors.

If this heater is being installed in an area where Black Dust is known to be a problem, and copper gas supply pipework is used, it is recommended that a filter having a stainless steel 50 micron mesh and suitable for Natural Gas is fitted at the inlet to the appliance immediately downstream of the main appliance isolation valve. The end user should be advised that the filter will require periodic cleaning or replacement at least once per year, during the annual service, or more often if the problem is severe.

4.2 Location

The location chosen for the air heater must permit:

- the provision of a satisfactory flue system and an adequate air supply.

- adequate space for servicing and air circulation around the air heater.

The heater(s) must not be installed in conditions for which it is not specifically designed e.g. where the atmosphere is corrosive or salty, and they are not suitable for outdoor use unless the CP/EA style is specified. CP/EA heaters must be installed on a plinth such that there is a minimum distance of 0.5m between ground level and the lowest point of any air inlet grilles. Where the location of the air heater is such that it might suffer external mechanical damage e.g. from overhead cranes, fork lift trucks, it must be suitably protected. CP heaters are for normal operation within an ambient temperature range of -10 to 25°C. The air heater must be installed in accordance with the rules in force and the relevant requirements of any fire regulations or insurance company's requirements appertaining to the area in which the heater is located, particularly where special risks are involved such as areas where petrol vehicles are housed, where cellulose spraying is carried out, in wood working departments etc.

IMPORTANT:

Heaters shall not be installed in:a) Those parts of spaces within buildings that have been

classified as hazardous areas as defined in BS 5345 : Part 2.

b) Where there is a foreseeable risk of flammable particles

or gases or corrosion inducing gases or vapours being drawn into either the heated air stream or the air for combustion. In such cases installation may only proceed if the air to be heated is ducted to the heater from an uncontaminated source, preferably from outside the building. The option of taking combustion air from the space is not permitted. In certain situations where only airborne particles are present it may suffice to fit filters on the main air inlet duct of the heater. Advice in these instances may be obtained from Powrmatic Ltd.

c) In areas subjected to significant negative pressures due to

extract systems.

4.3 Installing the Air Heater

If necessary consideration should be given to mounting the heater on resilient pads, or equivalent, to minimise transfer of noise and vibration to the structure of the building.

Floor mounted heaters must be installed on a level

noncombustible surface. Heaters mounted at high level must be supported on a purpose designed platform or framework that is suspended from vertical drop rods, chains or straps or mounted on specifically designed cantilever brackets from a non-combustible wall. The method of installation support must be capable of adequately supporting the weight of the unit (See Table 2, Page ?) and any ancillary equipment. Before installing the heater the existing structure must be inspected to ensure it is suitable. All supports should be protected against the effects of rust or corrosion. Whichever method of mounting the air heater is used the following minimum clearances for installation and servicing must be observed. To the front The depth of the heater To the rear 1.0m To at least one side 1.0m On the opposite side 0.5m Above the heater 1.0m

Any combustible material adjacent to the air heater and the flue system must be so placed or shielded as to ensure that its temperature does not exceed 65 °C. If the method of mounting allows for any movement of the heater it is essential that all gas, duct, and electrical connections to the heater are made with flexible connections to maintain continuity of connection.

4.4 Combustion Air Supply

In buildings having a design air change rate of less than 0.5/h, and where heaters are to be installed in heated spaces having a volume less than 4.7 m³/kW of total rated heat input grilles shall be provided at low level as follows:(1) for heaters of heat input less than 60 kW, the total minimum

free area shall not be less than 4.5 cm² per kilowatt of rated heat input.

(2) for heaters of heat input 60 kW or more, the total minimum

free area shall not be less than 270cm² plus 2.25 cm² per

kilowatt in excess of 60 kW rated heat input. Where the air heater(s) are to be installed in a plant room the plant room must have permanent air vents communicating directly with the outside air, at high level and at low level. Where only high level air vents are available, ducting down to floor level for the lower vents should be used. All air vents should have negligible resistance and must not be sited in any position where they are likely to be easily blocked or flooded or in any position adjacent to an extraction system which is carrying flammable vapour. Grilles or louvres should be so designed that high velocity air streams do not occur within the plant room. The basic minimum effective area requirements of the air vents are as follows: (a) Low Level (inlet)

(1) for heaters of total rated heat input less than 60kW:

9cm² per kilowatt of rated heat input.

(2) for heaters of total rated heat input 60kW or more:

Page 13

540 cm² plus 4.5 cm² per kilowatt in excess of 60 kW total rated input.

(b) High Level (outlet)

(1) for heaters of total rated heat input less than

60kW: 4.5cm² per kilowatt of rated heat input.

(2) for heaters of total rated heat input 60kW or more:

270 cm² plus 2.25 cm² per kilowatt excess of 60kW total rated input.

4.5 Flue System

A single wall tee piece is supplied with each heater and must be fitted to the flue outlet socket on the heater. A closed chimney system that conforms to the requirements of EN1856-1 and has a designation appropriate to the application must be connected to the outlet of this tee. The cross sectional area of the chimney serving the appliance must be not less than the area of the flue outlet of the air heater. The chimney must have a minimum height, from the heater to the flue terminal, of 2m. Horizontal runs of flue are not permitted. If necessary a single offset using two 45° bends can be included to avoid obstructions. The maximum equivalent resistance of the flue system must not exceed 20 pa. Details of how to calculate the resistance of the flue to be installed are given in Appendix A.

In order to minimise condensation the use of twin wall chimney is recommended. Where condensation in the chimney is unavoidable provision should be made for condensation to flow freely to a point at which it can be released, preferably into a gully. The condensation pipe from the chimney to the disposal point should be of non-corrodible material of not less than 22mm (3/4") size.

Facilities should be made for disconnecting the chimney pipe(s) from the air heater(s) for inspection and servicing purposes.

It is recommended that consideration be given to the fitting of a terminal at the chimney flue outlet, however, where the heater flue is less than 200mm (8") in diameter an approved terminal must be fitted.

The chimney must terminate in a freely exposed position and must be situated so as to prevent the products of combustion entering any opening in a building in such concentration as to be prejudicial to health or a nuisance..

The chimney must be supported independently of the air heater. A chimney support bracket that fits directly to the rear of the heater is available as an optional extra. The chimney terminal must not be installed so as to be less than:

- 300mm below an opening e.g. window, air brick etc.

- 200mm below eaves or gutter.

- 300mm from an internal or external corner.

- 1200mm from a surface facing the terminal.

- 1500mm vertically from another terminal on the same wall.

- 300mm horizontally from another terminal on the same wall.

- 2000mm from ground level.

4.6 Fuel Connection

4.6.1 Gas Connection (if applicable)

A servicing valve and union must be fitted at the gas inlet to the heater to facilitate servicing. The gas supply to the air heater must be completed in solid pipe work and be adequately supported. Heaters suspended by drop rods, straps or chains must have a flexible connection as the final link between the gas supply pipe work and the heater. Sufficient slack must be left in the connection to take account of normal movement of the heater.

Warning:

When completing the final gas connection to the heater do not place undue strain on the gas pipe work of the heater.

4.6.2 Oil Connection (if applicable)

Refer to the supplied burner installation instructions for details regarding oil supply options.

4.7 Electrical Connections

Wiring external to the air heater must be installed in accordance with the I.E.E. Regulations for Electrical Installations and any local regulations which apply. Wiring should be completed in flexible conduit.

Heaters are for use with 230V, 1N, 50Hz or 400V, 3N, 50Hz supplies (see heater data plate).

The method of connection to the main electricity supply must:-

- facilitate the complete electrical isolation of the heater(s) t

hat

will prevent remote activation of the heater during servicing.

- be in a readily accessible position adjacent to the heater(s).

- serve only the heater(s).

- have a contact separation of at least 3mm in all poles. See the accompanying wiring diagram for the heater electrical connections. All units are fully prewired and only require final connections for the incoming mains supply. Heaters not supplied with inbuilt time and temperature controls will also require completion of the external control circuit (230V) via a room thermostat, time clock etc. and, if applicable, the remote low level lockout reset. All heaters must be earthed. Reference must be made to Table 3 (Page 7) to ascertain the electrical loading of the unit(s) being installed so that cables of adequate cross-sectional area are used for the electrical installation. The length of the conductors between the cord anchorage and the terminals must be such that the current carrying conductors become taut before the earth conductor if the cable or cord slips out of the cord anchorage. All external controls must be of an approved type.

Heaters supplied less main fan must be electrically interlocked to the air movement system so that this is started in the same manner as the air heater fan would be viz. A connection from the appropriate heater terminal (see wiring diagram with the heater) must be made to one side of the fan motor contactor coil, the other side of the coil being connected to Neutral. Under no circumstances must the fan motor electrical supply be taken direct from the internal wiring of the heater.

4.8 Air Distribution System

For free-blowing units used in buildings having a low heat loss i.e. where single units are required to cover a large floor area, and in buildings with high roof or ceiling heights Calecon thermal economiser units should be fitted to ensure even heat distribution and minimise stratification. Care should be taken to avoid impeding the heater air throw with racking, partitions, plant or machinery etc. Various outlet configurations are available as optional extras to modify the air throw pattern to suit particular site conditions.

CP-G *D models are designed for use with duct work to more precisely define the point of air delivery, and /or provide ducted return air or ducted fresh air inlet. All ducting must be independently supported of the air heater.

All delivery and return air ducts, including air filters, jointing and any insulation or lining must be constructed entirely of materials which will not contribute to a fire, are of adequate strength and dimensionally stable for the maximum internal and external temperatures to which they are to be exposed during commissioning and normal operation. Where inter-joist spaces are used as duct routes they should be suitably lined with a fire-resisting material. A full and unobstructed return air path to the air heater(s) must be provided. If the air heater(s) is installed in a plant room the return air intake(s) and the warm air outlet(s) from the heater(s) must be fully ducted, into and out of the plant room to avoid interference with the operation of the heater from other equipment. The openings in the structure of the plant room through which the ducting passes must be fire stopped. Care must be taken to ensure that return-air intakes are kept clear of sources of smells and fumes, and where there is any possibility of pollution of the air by dust, shavings etc., precautions must be taken to prevent contamination.

Page 14

If necessary suitable barrier rails should be provided to prevent any combustible material being placed within 900mm of the outlets. Joints and seams of supply ducts and fittings must be securely fastened and made airtight.

It is recommended that ducting should be connected to the heater spigots via an airtight flexible coupling of noncombustible material. Before fitting coupling it must be ensured that a maximum clearance of 13mm will be maintained between the ends of the ducting and the heater spigots.

If required sound attenuators may be fitted in inlet and outlet ducts to reduce airborne fan noise. Materials used in outlet sound attenuators must be capable of withstanding 100 °C air temperature without any deterioration.

4.9 Room Thermostat Siting

If a remote room thermostat is used it should be fitted at a point which will be generally representative of the heated area as far as temperature is concerned. Draughty areas, areas subjected to direct heat e.g. from the sun, and areas where the air movement is relatively stagnant e.g. in recesses, are all positions to be avoided for siting the thermostat. The thermostat should be mounted about 1.5m (5ft) from floor level. Any room thermostat, frost thermostat, time clock etc. must be suitable for switching 230V, 5A and must be of the 'snap action' type to minimise contact bounce.

For electrical connections of external controls see the accompanying wiring diagram.

Page 15

1. Remove the sealing screw from the pressure test point located on the side of the gas inlet to the burner head and attach a pressure gauge. Remove the sample point cover plug from the outlet flue length and insert a CO2 measuring instrument.

5. Commissioning & Testing

5.1 Electrical Installation

Checks to ensure electrical safety must be completed by a competent person.

5.2 Gas Installation (if applicable)

The whole of the gas installation, including the meter, should be inspected and tested for soundness and purged in accordance with the recommendations of IGE/UP/1 or IGE/UP1A or IGE/UP/1B as appropriate.

5.2 Oil Installation (if applicable)

The whole of the oil installation, including the tank, should be inspected and tested in accordance with the recommendations of OFTEC.

5.3 Air Distribution System

The system should be checked to ensure that the installation work has been carried out in accordance with the design requirements.

Particular attention should be given to the correct arrangement of delivery ducts and registers, return air ducts and grills and general adequacy of return air paths.

For CP /*D heaters ensure that the total duct system resistance does not exceed the available air pressure of the equipment supplied refer to Table 2 (Page 7). If the duct system resistance is less than the available air pressure of the equipment supplied additional resistance must be introduced e.g. by adjustment of duct outlet nozzles and balancing of the duct system. Conversely if the duct system resistance is greater than the available air pressure of the heater supplied the system resistance must be reduced.

5.4 Lighting the Air Heater

5.4.1 Gas Fired Heaters

Note: Refer also to the burner instruction booklet supplied with the heater. This provides information on adjusting the burner, setting up the air pressure switches, system checks and fault finding detail.

5.4.1.1 Gas Controls Assembly - Soundness Check

1. Ensure the gas service valve at the inlet to the gas controls assembly is shut.

2. To prove soundness of the first main safety shut-off valve:a) Connect pressure gauge to the inlet pressure test point

on the main valve block or inlet pipework.

b) Open gas service valve and allow pressure to stabilise

before shutting it again. The valves are sound if no pressure drop is observed. If a pressure drop is observed do not proceed until the fault has been rectified. Remove pressure gauge and refit sealing screw in pressure test point.

5.4.1.2 Sequence Check

1. Ensure that the gas service valve is closed and that the main electrical supply to the heater is switched off.

2. Start the burner by setting the time clock and thermostat to call for heat or complete the external control circuit.

1. The max. air pressure switch must be set after all other adjustments have been made.

2. Begin with the switch at its highest setting and the burner working at the correct input for high fire.

3. Slowly adjust the pressure switch dial anti-clockwise, to decrease the set point, until the burner locks out. Immediately stop adjustment.

4. Now increase the set point by 0.1mb and restart the burner.

5. If the burner fails to start, or shuts down due to the pressure surge on ignition, increase the pressure switch setting by a further 0.1mb and restart the burner.

6. Continue until the burner reliably starts.

5.4.2 Oil Fired Heaters

5.4.2.1 Initial burner startup

1.Check that fuel is present in the tank and at the oil filter fitted on the front of the heater.

2. Check that fitted fire valves are open.

3. Refer to the burner instruction book and fit a pressure gauge (and vent valve if the burner is on a single pipe oil feed) to the oil pump.

4. Set the time clock and thermostat to call for heat or complete the external control circuit.

5. Turn ON the main electrical supply and check that the burner fan starts.

6. Note: This step is only for when a vent valve is being used. Open the vent valve. When air free oil issues from the vent

valve close the valve and the burner will fire when the ignition spark is present. (Note: This procedure may need to be repeated several times if the oil line cannot be purged of air within one ignition cycle. At the end of the unsuccessful ignition cycle the burner will go to lockout. Wait 2/3 minutes and then depress the red reset button on the burner control box to restart the ignition cycle.)

7. After completion of the pre-purge period the ignition spark will be energised and the burner oil solenoid valve will open and the burner will light.

Warning: If burner ignition cannot be achieved after 2-3 attempts do not continue to recycle through the ignition sequence but ascertain the cause and rectify.

WARNING:

If continued unsuccessful ignition attempts are made it is possible to accumulate a significant quantity of oil and oil mist in the combustion chamber which, if the burner then fires, can result in a dangerous situation. Any such accumulation of oil must be removed by safe means before any further attempt to light the burner.

5.4.2.2 Final Adjustment

1.Remove the sample point cover plug from the outlet flue length and insert a CO

measuring instrument.

2. Relight the burner. Check that the pump pressure is as specified on heater data plate. If adjustment of the pump pressure is necessary refer to the burner instructions and complete.

Appendix A

Calculation Of Flue System Equivalent Resistance

The pressure resistance of the flue system (Pr) can be calculated from

Pr = 1.5 * [(PFF*H/D+SRF)Qm/Wm2]

Where Pr = Pressure resistance of the flue system in pa

PRF = Pipe Friction Factor H = Effective flue height in m D = Internal Diameter of flue in m SRF = Sum of individual resistance factors Qm= Mean Density of the column of exhaust gas in kg/m3 Wm = Mean exhaust gas velocity in m/s

PRF

Can be calculated from PRF = 0.118*(0.21147/D0.4)

Where D = Internal Diameter of flue in m

SRF

Typical resistance factors for individual components are as follows

Segmented 90° bend 0.5 45° Elbow 0.4 Cowl 1.0

Qm = 97000/(300*Tm)

Where the mean temperature of the column of exhaust gas (Tm) can be calculated from

Tm = 288+((Te-TL)/0.2)*(0.18)

Where Te is the exhaust gas temperature in °C

TL is the external air temperature in °C

Wm = M/(A*Qm) Where A is the cross sectional area of the flue in m2

M is the exhaust gas mass flow in kg/s which is as follows for the various units CP 100 0.018 CP 500 0.125 CP 1500 0.3 CP 150 0.027 CP 600 0.14 CP 2000 0.4 CP 200 0.035 CP 700 0.145 CP 300 0.050 CP 800 0.16 CP 400 0.080 CP 1000 0.2
