Failure to follow these instructions can result
in product damage.
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 commercial 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

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 6: FLUE INSTALLATION
SECTION 6: FLUE INSTALLATION
6.1 Flue Installation
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
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 adequately 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.
Cut/Pinch Hazard
Wear protective gear during installation,
operation and service.
Edges are sharp.
Failure to follow these instructions can result
in injury.
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 7: AIR SUPPLY
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.
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 m3 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 cm2 per kW
of rated heat input
• Heaters above 70 kW heat input: 350 cm2 + 2.5
cm2 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
22 of 85
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 require 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.
SECTION 8: FUEL PIPE WORK
SECTION 8: FUEL PIPE WORK
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.
WARNING
• 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.
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.
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.

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.
24 of 85
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
SECTION 8: FUEL PIPE WORK
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
Figure 15: B. M. Oil Lifter
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.

DANGER
Electrical Shock Hazard
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.
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.
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.
9.2.4 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 burner 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.
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.

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.
10.2.4 Control - Gas-Fired Heaters
Refer to the burner manufacturers instructions for
further detail. Gas burners 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.
10.2.2 Set Gas Rate
1. Switch 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 Regulator (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.
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.
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 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. After burner 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.

10.2.5 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.
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 continuously 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.

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 valve 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)
44 of 85
SECTION 10: COMMISSIONING
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 must 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.
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
sequence 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.
To alter combustion 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)

COMBAT® CABINET HEATERS INSTALLATION, COMMISSIONING, OPERATION AND SERVICE MANUAL
Figure 20: Oil-Fired Heaters Control Box Sequence
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.
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
46 of 85
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 gauge 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

instructions in Section 11.3.1.
11.4 Simple Fault Finding (all models)
Some possible reasons for the heater not operating
are:
1. Gas supply not turned ON.
2. Electricity supply not turned ON.
3. The time and/or temperature controls are not
ON.
4. The Limit Thermostat may have operated. This
may be caused by an interruption of the electrical supply or failure of the distribution fan.
5. The burner supply plug has been disconnected.
If the Limit Thermostat persistently operates, there
is a fault which must be investigated by a contractor
qualified in the installation and service of gas or oilfired heating equipment.
NOTE: If the main fan runs continuously, the white
button (Page 49, Figure 22) may have been pressed
in - make sure it is pulled out. Alternatively, if a
remote fan switch is fitted it may be in the ON
position.

11.4.1 Simple Fault Finding (burner faults)
If the burner fails to ignite for any reason, it will go to
lockout. This will be indicated by the red light on the
heater or at the remote indicator (if fitted).
1. Press in and release the lockout reset button on
the burner or, if fitted, the remote reset.
Lockout should not occur during normal operation of
the heater and indicates there is a fault condition
which must be corrected.
11.4.2 Simple Fault Finding (oil fired heaters)
Make sure the appliance fuel valve is open and
there is oil in the tank. If the fuel tank or lines have
run dry, the fuel system will need to be vented. For
venting oil-fired heaters, See Page 45, Section 10.7
through Section 10.8.4.
11.4.3 Blocked Flue
If lockout lamp is illuminated call registered installer
to verify. See Page 46, Section 10.8.5.

14.4 Troubleshooting for Flame Supervision System
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.
Readings should be approximately as follows(For further details see burner manufacturer’s
