2.1 Laminated Wall Plate

A laminated wall plate is available for the heater as a permanent reminder of the safety instructions and the importance of the required clearances to combustibles. Affix the plate by peeling off the backing of the adhesive strips on the rear surface and position the plate on a wall near the heater (e.g. thermostat or ROBERTS GORDON

Controller).

A copy of the wall plate (P/N 91040095) is illustrated on the back cover. Know your model number and installed configuration. Model number and installed configuration are found on the burner and in the Installation, Commissioning, Operation and Service Manual. Write the largest clearance dimensions with permanent ink according to your model number and configuration in the open spaces on the plate.

2.2 Corrosive Chemicals

Roberts-Gordon Europe Limited cannot be responsible for ensuring that all appropriate safety measures are undertaken prior to installation; this is entirely the responsibility of the installer. It is essential that the contractor, the sub-contractor, or the owner identifies the presence of combustible materials, corrosive chemicals or halogenated hydrocarbons* anywhere in the premises.

* Halogenated Hydrocarbons are a family of chemical compounds characterized by the presence of halogen elements (fluorine, chlorine, bromine, etc.). These compounds are frequently used in refrigerants, cleaning agents, solvents, etc. If these compounds enter the air supply of the burner, the lifespan of the heater components will be greatly reduced. Warranty will be invalid if the heater is exposed to halogenated hydrocarbons.

2.3 National Standards and Applicable Codes

All appliances must be installed in accordance with the latest revision of applicable standards and local and national codes. This refers also to the electric, gas and venting installation. Note: Additional standards for installations in public garages, aircraft hangars, etc. may be applicable. The main relevant regulations for installation within the UK are:

• Gas safety (installation and use) regulations, 1984 and amendments - 1996.

• BS6230 - Specification for the installation of gas fired forced convection air heaters for commer- cial and industrial space heating of rated input exceeding 60 kW. (This standard also applies to oil-fired heaters, except for the fuel supply).

• BS6230 - Parts 2 & 3, fire precautions in the design and construction of buildings.

• BS6891 - Low pressure installation pipes.

• BS5410 - Codes of practice for oil firing. Part 2 installation of 44 kW and above output capacity for space heaters, hot water and steam supply purposes.

•Institute of Gas Engineers document IGE/UP/2.

•Building regulations.

•IEE regulations.

• Health and safety at work acts.

•Requirements of local authority, fire officer and insurance company.

3.1 Basic Information

Cabinet heaters are supplied with burners suitable for on/off operation as standard. As an option, two- stage (High/Low) operation is available for gas and oil-fired burners.

3.2 Location and Suspension

All models:

•Must be installed indoors within the heated space. Special versions are available for installation outdoors.

•Must be installed for floor standing vertical installation.

•Must be installed in a manner which allows all the upper panels and either of the lower side panels to be removed to provide access to all serviceable components.

•Must be placed on a firm, level, non-combustible surface that can support its weight. See Page 8, Section 4.1 for weight details.

• Special versions supplied with steel channels to support the heater are available and may be mounted horizontally. When installed horizontally, the heater will normally lie on its left side when viewed from the burner. The same clear- ances and comments on panels must be used, except for the side the heater lies on.

3.3 Required Clearances to Combustibles

Clearances are the required distances that combustible objects must be away from the heater to prevent fire hazards. Caution should be used when running the system near combustibles. Combustibles are materials, which may catch on fire and include common items such as wood, paper, rubber, fabric, etc. Maintain clearances to

combustibles at all times for safety.

Clearances around the heater and flue must be as indicated on Page 6, Figure 2 to ensure access for servicing, and correct operation. If clearances to

combustibles are not indicated, then installation clearances apply.

Check the clearances on each heater for the model heater being installed to make sure the product is suitable for your application and the clearances are maintained. Read and follow the safety guidelines below:

• Keep petrol or other combustible materials incl

uding flammable objects, liquids, dust or

vapours away from this heater or any other appli-

ance.

• Do not spray aerosols in the vicinity of this appliance.

• The stated clearances to combustibles represents a surface temperature of 50° C (90° F) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl sid- ing, canvas, tri-ply, etc) may be subject to degradation at lower temperatures. It is the installer’s responsibility to assure that adjacent materials are protected from degradation.

• Maintain clearances from heat sensitive equip- ment and workstations.

• Maintain clearances from vehicles parked below the heater.

• Maintain clearances from swinging and over- head doors, overhead cranes, vehicle lifts, parti- tions, storage racks, hoists, building construction, etc.

• In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain required clearances from the heater to the combu

stibles. Signs must be posted adjacent to the heater thermostat. In the absence of a thermostat, signs must be posted in a conspicuous location.

• Consult local Building Inspector, Fire Insurance Carrier or other authorities for approval of pro- posed installation when there is a possibility of exposure to combustible airborne materials or vapours.

• Hang heater in accordance to minimum suspen- sion requirements. Consult manufacturer.

• Affix the tag on a wall near the heater.

WARNING

Fire Hazard

Keep all flammable objects, liquids and vapours the minimum required clearances to combustibles away from heater.

4.6 Technical Data - Ecoflam 2-Stage Burners

NOTE: The air setting is a guide only. The final setting is subject to combustion testing.

When setting the minimum firing rate, a check must be made following the setting of the burner combustion. The check is made by running the heater on low fire for a minimum of 15 minutes at the full transport air rate and at typical ambient conditions. During the test, check that the flue gas temperature does not fall below 125° C (257° F). Should the flue gas temperature fall below 100° C (212° F), then the low fire gas setting must be increased to a value that will achieve 125° C (257° F) flue gas temperature; otherwise condensation may form in the heat exchanger and flue, causing rapid corrosion and short operational life.

NOTE: For adjustment of head setting, see Ecoflam Instructions.

SECTION 5: HEATER INSTALLATION

5.1 General

Heaters are designed for floor standing vertical installation. Special versions supplied with steel channels to support the heater are available and may be mounted horizontally. When installed horizontally, the heater will normally lie on its left side when viewed from the burner. The heater

should be placed on a firm, level, non-combustible surface that can support its weight. See Page 8, Section 4.1 for weight details.

5.2 Handling

SECTION 6: FLUE INSTALLATION

17 of 85

SECTION 6: FLUE INSTALLATION

6.1 Flue Installation

The flue must terminate outside of the building. Flues and air intakes must be a fully sealed system and correctly sized for the model. See Page 8,

Section 4.1. Flues should be assembled as on Page

18, Figure 5 through Page 21, Figure 13. The joints

between the flue and the roof or wall must be properly sealed. If the flue passes through a wall or ceiling of combustible material it must be enclosed by a sleeve of non-combustible material and be separated from the sleeve by at least a 25 mm (1") air gap. For double walled flue pipe conforming to BS 715, the 25 mm (1") separation distance should be measured from the outside surface of the inner liner. For double wall flue pipe conforming to BS 4543-2 and 3, the external skin and air gap constitutes insulation to a standard where no extra clearances to combustibles material is required other than normal installation tolerances.

Flues must be ade

quately supported so that the

heater does not bear the weight of the flue.

For straight and offset flue termination, See Page 18, Figure 5 and Figure 6.

Horizontal Flue Installation

Horizontal flue should be fitted ensuring a slight gradient approximately 2° towards the terminal. Where condensation is likely, traps should be included to encourage the condensate to flow freely to a point from which it may be released, preferably into a gully. Condensate must not be allowed to drain back into the heater as this could result in corrosion and damage. The condensate pipe from the flue to the disposal point must be made from corrosion resistant pipe of not less than 25 mm (1") internal diameter.

90° bends and horizontal pipe must not be used in flues except for the immediate connection to a room-sealed heater [1 m (3.5') max]. 135° bends

are used to offset the flue as on Page 18, Figure 6. If condensation is likely to occur in the flue, then provision should be made for drainage. When designing the flue system, the prevention of the formation and entrapment of condensation must be a key consideration.

Only single wall stainless steel flue is to be used on oil-fired cabinet heaters.

WARNING

Carbon Monoxide Hazard

Heater must be vented.

Heater must be installed according to the installation manual.

Failure to follow these instructions can result in death or injury.

WARNING

Fire Hazard

Keep all flammable objects, liquids and vapours the minimum required clearances to combustibles away from heater.

Some objects will catch fire or explode when placed close to heater.

Failure to follow these instructions can result in death, injury or property damage.

WARNING

Cut/Pinch Hazard

Wear protective gear during installation, operation and service.

Edges are sharp.

Failure to follow these instructions can result in injury.

SECTION 7: AIR SUPPLY

7.1 Room Sealed Installation

When installed as a room sealed heater, the air for combustion is drawn in from outside the building. It is important to ensure that there is adequate ventilation to provide air for the distribution fan/s.

7.2 Open Flued Installation

It is important to ensure that there is adequate air supply at all times for both combustion and heating requirements in accordance with local and national codes. When installed in this mode, the air supply to the heater must also be fitted with a low resistance terminal to prevent the ingress of debris. See Page 15, Figure 3 or Page 16, Figure 4.

7.2.1 Heaters Installed Within the Heated Space

Where the volume of the heated space is greater than 4.7 m

per kilowatt of total rated heat input and the air change rate is at least 0.5/h, additional high and low level ventilation will not be required.

For a building having an air change rate less than

0.5/h, ventilation will be necessary in accordance with local and national codes. Ventilation direct to outside must be provided as follows:

• Heaters up to 70 kW heat input: 5.0 cm

per kW

of rated heat input

• Heaters above 70 kW heat input: 350 cm

+ 2.5

per kW of rated heat input above 70 kW

7.3 Building Ventilation

Where ventilation is required, air must be taken from an outside point where it is not likely to be contaminated or obstructed.

Where natural ventilation is used, suitable ventilation with outside air at low level must be provided in accordance with Section 7.2.1 and local and national codes.

Where mechanical ventilation is used, extract rate must be 5% - 10% less than the inlet rate. The

mechanical ventilation must be interlocked with the burner on the heater.

7.4 Isolated Equipment Rooms

Ventilation must prevent the isolated equipment room temperature from exceeding 32° C as well as prevent any negative air pressure within the room. Any isolated equipment room containing air heaters will requ

ire permanent air vents direct to outside air

in compliance with local codes. Where natural ventilation is used, suitable

permanent openings at low and high level, communicating directly with the outside air, must be provided.

Where mechanical ventilation is used, extract rate must be 5% - 10% less than the inlet rate. The mechanical ventilation must be interlocked with the burner on the heater.

WARNING

Explosion Hazard

Equipment must have access to uncontaminated air at all times.

Failure to follow these instructions can result in death, injury or property damage.

Page 29

SECTION 8: FUEL PIPE WORK

23 of 85

SECTION 8: FUEL PIPE WORK

It is important that the gas supply pipe and the electrical connections do not support any of the heater’s weight. A gas meter is connected to the service pipe by the Gas Supply Company. Any existing meter should be checked, preferably by the company, to ensure that the meter is adequate for the rate of gas supply required. Installation pipes must be fitted in accordance with local and national codes. Pipe work from the meter to the heater(s) must be of adequate size.

8.1 Connections

Connect the heater to the gas supply, ensuring that the final connections are as follows:

•Gas supply pipe is run in medium or heavy gauge tubing in compliance with local and national codes.

• The gas supply pipe is adequately sized to carry the total volume of gas for the complete installation.

• An isolating valve and union connection should be used and fitted into the supply adjacent to the heater.

IMPORTANT - The complete installation must be purged and tested for gas soundness in accordance with local and national codes.

• Check the pipe and tubing ends for leaks before placing heating equipment into service. When checking for gas leaks, use a approved leak detection fluid; never use an open flame.

WARNING

Explosion Hazard

Leak test all components of gas pipe work before operation.

Gas can leak if pipe work is not installed properly.

Do not high pressure test gas pipe work with heater connected.

Failure to follow these instructions can result in death, injury or property damage.

Figure 14: Gas Connection

8.2 Fuel Oil Supply

8.2.1 Fuel Storage Tank

The fuel storage tank should be located outside the building as close as possible to the heater. The tank must be installed per local and national codes.

8.2.2 Fuel Pipes

The fuel pipes must be sized to ensure an adequate supply of oil to the entire installation. Galvanised pipe must not be used for oil installations. The fuel pipe must terminate at each heater with an isolating manual valve, a fire valve and a fuel filter. See Page 16, Figure 4. The fusible link of the fire valve should be installed 100 mm (4 in) above the burner. The heater’s oil burner pump inlet is provided with a flexible oil line which should be used for the final connection. When making the final connection to the heater, do not block any of the removable panels of the heater. All COMBAT

oil-fired cabinet heaters are supplied with burner pumps fitted for one pipe systems.

8.2.3 Gravity Feed Systems

The simplest installation is a gravity feed system. This system relies on the head of the fuel to push the fuel through the system. See Page 16, Figure 4.

8.2.4 B. M. Oil Lifter

Where a gravity feed system cannot be used, a B. M. oil lifter may be used for small installations up to the equivalent of a single model 050 on minimum lift or a single model 020 on maximum lift. The fuel output from the oil lifter is gravity fed. The B. M. oil lifter requires a constant 230 V 50 Hz 1 Ø electrical supply. The maximum pipe size to be used on the suction side is 1/4" ID, 5/16" OD (8 mm). For maximum loading of oil lifters See Page 25, Figure 15. Consult the manufacturer’s information regarding the need to prime these devices.

8.2.5 Pressurised Systems

See Page 26, Figure 16. For larger installations, a pressurised system may be used. In this type of

Page 31

SECTION 8: FUEL PIPE WORK

25 of 85

system, the pump draws fuel from the tank, then pushes it through the installation under pressure. The pressure is controlled at the pump by a pressure relief valve at approximately 0.8 BAR (12 psi). When a pressurised system is used, a pressure reducing valve set at approximately 0.3 BAR (5 psi) should be installed on the fuel inlet to each heater

after the manual isolating valve. This protects the oil pump from the danger of possible over pressure under fault conditions. The electrical supply for the pump installation will depend upon the type of pumps chosen, but will normally be set to run continuously.

SECTION 9: WIRING AND ELECTRICAL INFORMATION

27 of 85

SECTION 9: WIRING AND ELECTRICAL INFORMATION

9.1 Electrical Supply

A 230 V 50 Hz 1 Ø supply is required for all heater Models 015 to 030 connected to the heater terminals L1, N and Earth.

Standard models 040 to 0100 and all High Flow models require a 400 V 50 Hz 3 Ø and neutral supply connected to the heater terminals L1, L2, L3, N and Earth.

All heaters and controls must be correctly earthed. All external wiring must comply with the relevant IEE and local regulations and be carried out by a qualified electrician.

Polarity "L & N" must be correct. The voltage between neutral and earth should be 0 and never exceed 15 volts.

An isolator with a contact separation of at least 3 mm (.12

") on all poles should be installed adjacent

to the heater, but not attached to it, to disconnect all supplies to the heater and where necessary to isolate the remote control panel.

9.2 Remote Controls

The heater is designed to be operated by controls installed remotely from the heater. See Page 28, Section 9.3. through Page 39, Section 9.14.

9.2.1 Burner Controls (Thermostat)

Controls to operate the burner must be voltage free contacts connected between terminals 2 and 3 of the main terminal block.

9.2.2 Positioning Room Thermostats or ROBERTS GORDON

Control

A room thermostat or Roberts-Gordon Europe Limited control should be mounted on a wall or column at a height of approximately 1.5-1.8 m (5'-6') from the floor to measure the ambient temperature.

It should be clear of both cold draughts and the direct path of warm air from the heater.

9.2.3 Remote Frost Thermostat

When required, connect to terminals 2 and 3 in the main terminal block. Locate the thermostat within the heated space adjacent to the most vulnerable equipment that requires protection.

See Page 28, Section 9.3 through Page 39, Section

9.14.

9.2.4 Controls for High/Low Burner Operation

For heaters with a high/low burner, the controls will need to provide two stage signal to operate these burners. This is best provided by a two stage thermostat. The thermostat may control the heater outlet temperature if the heater is designed for a duct distribution system or the room temperature. The site wiring will be across terminals 2 and 3 for any time control and the on/off function of the burner (stage two), and across terminals 7 and 8 for the high fire (first stage) setting.

The b

urner will then operate as follows:

Temp. from cold up to the 1st set point..................

............................................ Full fire at max. rate

Temp. above 1st set point up to 2nd set point........

............................................ Low fire at min. rate

Temp. above 2nd set point ...............................Off.

9.2.5 Remote Fan Controls

The fan will operate automatically providing there is a constant 230 V supply to the main terminals.

A switch or control wired between terminals L & 1 in the terminal block will allow external control of the fan(s).

The fan may be controlled to operate continuously from an external control, with the burner cycling on and off, providing that the fan run-on at close down is not impaired.

DANGER

Electrical Shock Hazard

Disconnect electric before service.

More than one disconnect switch may be required to disconnect electric from equipment.

Equipment must be properly grounded.

Failure to follow these instructions can result in death or electrical shock.

All pre-commission checks must be carried out before commissioning the heater.

1. Check that all site wiring is connected in accordance with the appropriate wiring diagrams shown on Page 28, Section 9.3 through Page 39, Section 9.14.

2. Check the correct fuse size is fitted in the local supply isolator. See Page 11, Section 4.4.

10.1.3 Polarity Test - 1 Ø

10.1.4 Polarity Test - 3 Ø

Voltage between each phase L1, L2 and L3 and Earth or Neutral should be approximately 230 V. Voltage between any 2 phases should be approximately 400 V. Test Neutral to Earth as single phase.

10.1.5 Fan Rotation Check

Switch on the electricity supply at the isolator and the manual switch to "fan on" (if no remote fan switch is installed, press the white button on the fan/limit thermostat). On 3 Ø heaters, check the rotation of the main fan. Rotation should be in the direction of the arrow shown on the fan housing. If rotation is not correct, turn off the isolator and change over any t

wo of the incoming supply phases and recheck. It

will be necessary to remove the lower front or right

side panel to see fan rotation.

10.1.6 Fan Motor Overload Check

On 3 Ø belt drive heaters, check the correct settings of the fan motor overload. This should be 0.2 A above the rated current on the heater data plate. See Page 11, Figure 4.4. The belt tension and alignment should also be checked and adjusted as shown on Page 52, Figure 23.

10.1.7 Mechanical Checks

1. Check that the flue is installed in accordance with these instructions and local regulations.

2. Check that the settings of the Combination Fan/ Limit thermostat are correct - See Page 41, Figure 17.

Figure 17: Combination Thermostat (all models)

10.1.8 Burner (gas heaters)

Two-stage (High/Low) burners have additional specific requirements. Follow the manufacturer's instructions, the data provided on Page 11, Section

4.4 through Page 13, Section 4.7, and the commissioning instructions on See Page 43, Section 10.3.

10.1.9 Gas Supply

All aspects of the gas installation, including the gas meter, must be inspected, tested for so

undness and purged in accordance with local and national codes. Ensure that the air is fully purged from the heater inlet pipe up to the main gas valve inlet test nipple. Adjust the pressure switch located on the Dungs gas valve to 50% of its minimum inlet working pressure.

10.1.10 Before Operating the Heater

Ensure the burner head, air damper and pressure switch settings are adjusted for the correct burner in accordance with the Data Tables on Page 11, Section 4.4 through Page 14, Section 4.8 (see the burner reference letter on data plate). To ensure that all the controls are in safe working order, operate the heater for the first time with the isolating gas valve turned off.

1. Turn off the gas isolating valve

2. Using the installed external control, turn on the burner. The automatic sequence w

ill now begin

as described on Page 43, Figure 18.

There will be no ignition of the burner and lockout will occur, which proves the controls are operating correctly.

10.2.1 Fire the Burner for Dungs Combination Gas Valves

1. Open the gas isolating valve.

2. Connect a suitable pressure gauge to the burner pressure test point.

3. Reset the lockout button of the control box and the burner should now fire. If lockout should occur when the main gas valve energises, repeat 3 or 4 times. If after several attempts the burner does not fire, then turn the main gas governor adjusting screw 3 turns clockwise. See Page 41, Section 10.2 and repeat until the burner fires.

10.2.2 Set Gas Rate

1. S witch on again and allow the burner to fire and to settle for a few minutes.

2. Adjust the main gas burner pressure to the value given in the relevant Data Table for the model concerned using the Main Gas Regula- tor (accessed under the swivel cover).

The results of setting the gas flow rate by using burner pressure only can lead to quite wide variations in heat input due to the nature of the burners used. NOTE: If the correct burner pressure cannot be reached, then check the inlet pressure to the valve, with the burner firing. See Technical Data Tables on Page 11, Section 4.5 for inlet pressure requirements.

Do not continue to adjust the regulator if the pressure is not changing.

If the inlet pressure is too low to allow the correct burner pressure setting, then the gas inlet pressure must be corrected before completing the commissioning.

10.2.3 Check Gas Rate

It is important to check that the gas rate set during the commissioning is within ± 5% of the requ

ired flow rate. This may be achieved by checking the gas flow to the heater wherever possible by using the gas meter and timing the flow through the meter. The results should be compared with the required flow rate for the model given in the Data Tables, adjusting the burner pressure to correct for any error. Checking the gas rate must be carried out with all other appliances including any pilots, turned off.

1. Af t e r b urner pressure adjustment, allow the heater to operate for at least 15 minutes and then re-check settings.

2. Remove the manometer and refit all covers to the valve and tighten the screw of the outlet pressure tap.

3. Check gas flow rate at gas meter.

10.2.4 Control - Gas-Fired Heaters

Refer to the burner manufacturers instructions for further detail. Gas bu

rners have two pressure switches, one is configured to cover combustion air and reaction to increases in combustion chamber pressures. The second pressure switch is used for monitoring the incoming gas supply pressure. NOTE: The low gas pressure switch should be set at 50% of the recorded inlet working gas pressure.

10.2.5 Description of Gas-Fired Heater Control

The gas-fired burner fitted to all cabinet heaters is controlled by a full sequence plug-in control. This control ensures the safe start and stop sequence and also monitors the safe presence of a flame and burner air pressure.

10.2.6 Sequence of Operation - Single Stage Burner

1. With the external controls on calling for heat, and the pressure switch at rest, the burner fan will switch on after the control does a "self check".

NOTE: If the pressure switch contacts (normally closed) are open, the heater will not start.

2. The combustion air fan t

urns on and the pressure switch contacts close within the next 5 seconds to indicate sufficient combustion air or lockout will occur.

3. The sequence continues with a purge period with the burner fan running.

4. The electrical ignition switches ON at the end of the purge period.

5. The main gas valve opens and once a flame has been established, this remains open until close down. The flame probe is now continu- ously monitoring for the safe presence of flame.

6. Three seconds later, the electric ignition turns off, leaving the gas flame to be proved as stable.

7. The control is now in its normal run position.

8. If the flue becomes blocked during the units operation, the unit will deactivate and the lock- out indicator light will activate.

10.3 Commissioning the Two-Stage (High/Low) Burner (gas heaters)

High/Low burners have additional specific requirements. Follow the burner manufacturer's instructions and the data provided on Page 11, Section 4.4 through Page 14, Section 4.8.

10.3.1 Set Gas Rate

1. S witch off and refit the main gas valve plug (removed earlier to allow the main gas valve to operate).

2. Switch on again and allow the burner to fire and to settle for a few minutes.

3. Adjust the main gas burner pressure to the value given in the relevant Data Table for the model concerned using the Main Gas Regula- tor (accessed under the s

wivel cover).

Do not continue to adjust the regulator if the pressure is not changing.

If the inlet pressure is too low to allow the correct burner pressure setting, then the gas inlet pressure must be corrected before completing the commissioning.

10.3.2 Check Gas Rate

It is important to check that the gas rate set during the commissioning is within ± 5% of the required flow rate. This may be achieved by checking the gas flow to the heater

wherever possible by using the gas meter and timing the flow through the meter. The results should be compared with the required flow rate for the model given in the Data Tables, adjusting the burner pressure to correct for any error. Checking the gas rate must be carried out with all other appliances including any pilots, turned off.

1. Af t e r b urner pressure adjustment, allow the heater to operate for at least 15 minutes and then re-check settings.

2. Remove the manometer and refit all covers to the valve and tighten the screw of the outlet pressure tap.

3. Check gas flow rate at gas meter.

10.3.3 Control - Gas-Fired Heaters

For High/Low, follow the general sequence as described below and also have extra functional stages related to air damper positions. Refer to the burner manufacturers instru

ctions for further detail. Gas burners have two pressure switches; One is configured to cover combustion air and reaction to increases in combustion chamber pressure. The second pressure switch is used for monitoring incoming gas supply pressure.

10.3.4 Description of Gas-Fired Heater Control

The gas-fired burner fitted to all cabinet heaters is controlled by a full sequence plug-in control. This

Always disconnect the power supply before installing or removing the control unit. Do not attempt to open or carry out repairs on the control unit.

Page 50

control ensures the safe start and stop sequence and also monitors the safe presence of a flame and burner air pressure.

10.3.5 Sequence of Operation - Two-Stage Burner

1. With the external controls on calling for heat, and the pressure switch at rest, the burner fan will switch on after the control does a "self check".

NOTE: If the pressure switch contacts (normally closed) are open, the heater will not start.

2. The combustion air fan turns on and the pressure switch contacts close within the next 5 seconds to indicate sufficient combustion air or lockout will occur.

3. The sequence continues with a purge period with the burner fan running.

4. The electrical ignition switches ON at the end of the purge period.

5. The main gas valve opens and once a flame has been established, this remains open until close down. The flame probe is now continu- ou

sly monitoring for the safe presence of flame.

6. Three seconds later, the electric ignition turns off, leaving the gas flame to be proved as stable.

7. The control is now in its normal run position.

8. If the flue becomes blocked during the units operation, the unit will deactivate and the lockout indicator light will activate.

After setting the minimum burner input and combustion, the following check must be made: Run the heater on low fire for a minimum of 15 minutes. Check the flue gas temperature. If the flue

gas temperature falls below 125° C, increase the low fire gas setting until the temperature reaches 125° C, otherwise condensation may form.

10.4 Motor Starter and Thermal Overload

On belt-driven models, the motor is controlled by a direct on-line contactor starter fitted with thermal overload protection. If the thermal overload operates, the main fan will not run. To reset, press the reset button on the o

verload unit.

NOTE: For models with a 5.5 kW motor or larger, the direct on-line starter will be replaced by an automatic starter. The overload should be set to indicate approximately 0.2 A above the normal running current of the heater. See Page 11, Section 4.4.

10.4.1 Burners

For details of the packaged burners, see the manufacturer's instructions and Page 11, Section

4.5 through Page 14, Section 4.8. When reading the data tables, ensure that the correct table for the burner and gas valve installed is being used. The data tables are listed under a burner reference letter which can be found on the heater data plate.

10.5 Gas Valves Dungs Combination Gas Valve

All model 015 - 030 gas-fired burners operate as direct main flame ignition and have no separate start gas train. All other models operate with a first stage start gas flame supplied from a start gas train containing a start gas pressure regulator and two safety shut-off valves, for all gas types.

The main gas is released at the second stage, and the combination main gas valv

e block contains a main burner pressure regulator and two safety shutoff valves, for all gas types. See Page 44, Figure

19. Please refer to the manufacturer's instructions for setting the controls.

Figure 19: Gas Train Circuit for Dungs Gas Valves (all models)

Page 51

SECTION 10: COMMISSIONING

45 of 85

10.5.1 Main Gas Valves

Refer to the relavant Ecoflam burner and gas train installation manuals supplied with your heater for the position of the burner pressure regulator. This must be used to set the burner pressure indicated in the data tables in Section 4. For two-stage, the Dungs gas valve, please refer to the burner manufacturer's instructions for setting the controls.

10.5.2 Throughput Adjuster

These valves have a throughput adjuster fitted to the second main gas valve. Refer to the relavant Ecoflam burner and gas train installation manuals, supplied with your heater. When replacing a gas valve, ensure that this device is set in the fully open position by releasing the locking screw

and turning the "V MAX" fully counterclockwise towards the "+" and then retightening the locking screw.

10.5.3 Rate of Opening

This device is a hydraulic damper which slows down the rate of opening of the second main gas valve to give a smooth main gas ignition. This is preset at the factory at the slowest setting and will need no further adjustment. If a new valve is fitted, then remove the plastic screw on top and with a small screwdriver turn the "V Start" screw fully clockwise towards the "-" and refit the plastic cover.

10.6 Combustion Testing (all models)

Combustion quality must be tested to prove correct heater operation. Incorrect results will indicate faults with the installation or appliance. Combustion testing m

ust be carried out with all covers in place. The flue gas is sampled in the flue, within 1 meter of the heater. The values of CO2 should be between 9.5% and 10.0% for natural gas and 11% for LPG, depending upon the model. The CO will be up to 80 ppm (0.008%) dry, air free, depending upon the model. Temperature rise of the flue gases above ambient should be approximately 160°C to 180°C. Seal the sample test hole in the flue after testing.

To a l t er c o m b ustion performance, open/close the combustion air damper to reduce or increase these values. Once adjusted to the optimum combustion setting, lock the air damper into position. Repeat the steps on Page 42, Section 10.2.3.

10.6.1 Pressure Switch Setting of the pressure switch must only be

carried out as part of a complete commission which includes combustion testing. For adjusting the air pressure switch, see Ecoflam instructions.

10.6.2 Complete the Commissioning

Ensure that all covers are fitted correctly and all test points are properly sealed.

10.7 Commissioning the Burner (Oil Heaters)

Check all valves betw

een the fuel tank and the

heater are open, including the fire valve.

Ensure that oil is available at the heater inlet and that the air has been vented from the fuel pipe installation. Vent the air by opening the bleed screw on top of the fuel filter. On pressurised systems, check that the installation is running at the correct pressure. B.M. oil lifters will need priming.

10.7.1 Burner Settings

Ensure that the burner head and air damper settings are adjusted for the correct burner and that the correct atomising nozzle is fitted. See Page 13, Section 4.7 and the burner reference number on the data plate.

10.7.2 Preparation for Burner Pressure Test

Attach a pressure gauge 0-15 BAR (0 - 200 psi) to the burner pump pressure test port. (See manufacturer's information). A test manifold gives you the facility for the connection of the pressure gauge and the venting of the pump.

10.8 Control - Oil-Fired Heaters

For High/Low oil burners, follow the general seq

uence as described below and also have extra functional stages related to air damper positions. Refer to the burner manufacturer’s instructions for further detail.

10.8.1 Description of Oil Fired Heater Control

The oil fired burners fitted to the heater are controlled by a fully automatic control and photoelectric flame monitor unit. This control ensures the safe start, ignition and stop sequence and also monitors the flame. If the flame should fail the control will go into "lockout". The button on ther front of the control will illuminate to indicate lockout. Press the button to reset the control to restart the burner firing cycle.

Page 52

COMBAT® CABINET HEATERS INSTALLATION, COMMISSIONING, OPERATION AND SERVICE MANUAL

46 of 85

Figure 20: Oil-Fired Heaters Control Box Sequence

10.8.2 Sequence of Operation

The operating sequence is as follows: With the external controls on and calling for heat, the burner fan and electric ignition will switch on. After a combustion air purge of approximately twelve seconds, the oil solenoid valve will open and the burner will fire. After another five seconds, the electric ignition is turned off and the burner will go into its normal run position. The photo cell continuously monitors the safe presence of the flame. When the temperature control is satisfied, the control box will turn off all its outputs simultaneously and return to the rest position for the beginning of the next sequence.

10.8.3 Fault Conditions

If at any stage during normal running the photo electric cell fails to detect the flame, the control will switch off and make an instant restart attempt. If the flame signal is still missing, "lockout"

will occur. If the flame is not detected by the photo cell during a normal start, there will be no restart attempt and "lockout" will occur in approximately 17 seconds after the start. If a flame is detected during the first 12 seconds

(purge), the solenoid valve will not open and the control will "lockout". For the control sequence, see Page 46, Figure 20.

10.8.4 Switching On

Turn on the heater with the external controls. (Heat ON). If the "Lockout Reset" button is illuminated, press to reset. The combustion air fan and electric ignition should work immediately. Vent the burner oil pump at the same time by loosening the pump vent port (pump must be running). If the burner goes into "lockout" before the pump has vented, wait one

minute, then reset the control box and repeat Section 10.8.4 until all the air has been vented from the pump and the burner fires. NOTE: The burner plug and socket may be used to turn off the burner during commissioning.

10.8.5 Blocked Flue

A safety device which measures the combustion chamber and flue is fitted on this heater. if the pressure exeeds the factory set maximum pressure limit, the heater will fail safe and prevent the burner from firing. In the event of this happening one indicator lamp located on the front of the heater will be illuminated - This fault should be investigated by a competent person.

10.8.6 Adjust Burner Oil Pressure

Adjust the burner oil pressure to the value in the data table for the burner reference letter and burner manufacturer's information for details of the burner oil pump. When completed, turn off burner and remove test ga

uge and refit plug.

10.8.7 Set Combustion Air

The combustion air must be set. Measure the emissions in the flue at a point within one metre from the outlet of the heater and adjust for the highest carbon dioxide (CO2) levels obtainable, usually 10.5

- 11.0%, while making little or no smoke (smoke number 0-1). The test must be carried out with all covers fitted and after the heater has been running for 15 minutes.

10.8.8 Complete the Commissioning

Test the burner for correct start and stop operation several times. Check that all safety devices operate

Always disconnect the power supply before installing or removing the control unit. Do not attempt to open or carry out repairs on the control unit.

The flame supervision system is different for gas-fired and oil-fired heaters but may be tested in a similar way. Gas-fired heaters use a rectification flame probe to monitor the flame. Oil-fired heaters use a photo sensitive cell to monitor the flame. To connect a suitable meter into the circuit to monitor the flame signal current, disconnect one of the wires to the monitor (there is only one for gas-fired). Connect a suitable DC ammeter between the terminal just disconnected and the wire taken from it. Should the meter read backwards, then reverse its connections.
