Section 1. General Specification
1.1 General Information - Standard Models
COMBA ® cabinet warm air heaters are self contained units fitted with a packaged burner and are supplied ready for
installation on site to be used with external controls.
he burner controls which form part of the packaged burner are designed for safe operation between
-20°C to 60°C. However the heater should not be operated in ambient temperatures above 32°C .At Ambient temperatures
above 29°C some models may require the maximum heat input to be reduced, seek advice from Roberts-Gordon UK
Ltd. under these circumstances
he standard PGP or POP heater is the free standing model.
Models are available with various options are:
PGPH & POPH models for use in the horizontal (suspended) mode
PGPE & POPE weatherproof models for external siting
HF range of 'High Flow' gas fired and oil fired heaters with higher air flows
PGP/H and HF/H gas fired ranges for Ecoflam high /low burners
PGP/M and HF/M gas fired ranges for Ecoflam fully modulating burners
POP/H and HF/H oil fired ranges are also available with Ecoflam High /Low burners
COMBA ® cabinet heaters are available with heat outputs ranging from 47.3kW to 290kW.
All heaters are fitted with fully automatic 'packaged' forced draught oil fired or gas fired burners manufactured for
Roberts-Gordon UK Ltd.
he heater cabinets are manufactured in Zintec coated mild steel which is finished with a stove cured powder coat
paint.
he combustion chambers are of high grade stainless steel construction. he heat exchangers are mild steel tubular
all welded construction.
Centrifugal fan(s) located in the base of the heater cabinet provide heated recirculation air, which is distributed from the
top of the heater through the fully adjustable louvred outlet heads.
he fan(s) are either direct drive or belt driven dependent upon model:
Models 015 - 050 inclusive - Direct Drive (except High Flow)
Models 060 - 0100 inclusive - Belt Drive
he required electrical supply is: 230 volt 50Hz single phase on models 015 to 030 and 400 volt 50Hz three phase
and neutral on models 040 to 0100 (Models PGP and POP 040 and 050 are also available as single phase belt drive
to special order). All High Flow models require a 400V, 50Hz, three phase and Neutral electrical supply.
ON/OFF control, temperature control, time control, and frost protection are available as a remote control which needs
to be site wired to afford proper operation of the heater. Alternatively, any remote energy controls may be used which
must be installed in accordance with Section 4.3.
Each heater must be fitted with its own natural draught flue in accordance with local regulations and the instructions in
this booklet. Fig. 1.1 shows the basic parts of the heater.

1.2 Basi Information - High Flow (HF) Models
1.2.1 Introduction
he COMBA ® HF range of cabinet heaters are designed specifically to meet the needs of designers who require a
high fan performance with the heat input that would be expected for the standard COMBA ® cabinet range of heaters.
he result of this is to produce a lower average temperature rise over the heat exchanger dependant upon the final air
flow of the installation.
High Flow Heaters are fitted with burners to the same specification as the PGP or POP 30 to 50 models for either gas
or oil firing.
COMBA ® High Flow cabinet heaters are available in 10 sizes dependent upon air flow required, with a choice of 3
heat outputs; 81kW, 115kW and 145kW.
1.2.2 Electrical Supply
he HF range of heaters all require a 400v three phase and neutral 50Hz supply to the main terminals within the heater.
1.2.3 Controls
he HF range of heaters are designed to be operated with external controls and are provided with electrical terminals
to accommodate these.
hey may be controlled in the same manner as the PGP or POP models using Roberts-Gordon controls or other
suitable controls.
1.2.4 Fan Operation
All of the HF range of heaters are provided with a fan operation relay as well as the combination fan thermostat to
ensure that the fan will run correctly even though the temperature rise may be low.
he HF 40v3 and HF 50v2 to 50 v4 models are fitted with 5.5kW or 7.5kW motors that are controlled via an automatic
star/delta starter built into the heater to replace the direct on line starter used for the remainder of the range.

CABINET HEATER
1.3 Heater Operation (On/Off)
Once the heater has initially been switched on using the remote controls, the operation of the heater becomes automatic
under the control of the remote time/temperature controls (as fitted on site) and the safety devices.
When the external controls call for heat, the control box of the fully automatic burner checks that all systems are in a
safe and ready position, and then initiates a start sequence. It then constantly monitors safe operation of the burner
(see Section 2.2 & 2.3 for details).
When the heat exchanger has been sufficiently heated, the built in fan thermostat turns on the main fan(s) and warm
air is distributed from the top of the heater.
Note: On horizontally mounted heaters, High Flow heaters, heaters fitted with high/low or modulating burners and
some fully ducted heaters, the fan will come on during the burner firing cycle and not wait for the temperature rise. his
is to ensure that there is always a proper operation of the heater under all possible conditions.
At the close down of the external controls, the burner shuts off and the main fan(s) continue to run until the fan
thermostat detects a drop in leaving air temperature, sufficient to turn it off. he heater is then at rest until the beginning
of the next cycle.
If for any reason the main fan should fail or the air flow through the heater is reduced, then the built in limit thermostat
will cause the burner to go to safety shut down lockout. his condition will remain until the fault is corrected and the
manual red reset button is operated at the limit thermostat.
1.2.1 Heater Operation (High/Low)
For burners which are capable of High/Low operation, a two stage thermostat will be required to be installed on site to
alow the burner to operate On/Off and High/Low dependant upon conditions (see 4.3.1.1 for details)
1.2.2 Heater Operation (Fully Modulating)
For gas burners only which are capable of Fully Modulating operation the burner comes complete with a temperature
control system. he sensor of this system needs to be installed on site (see 4.3.1.2) to allow the burner to vary the heat
input to maintain a constant control temperature.
WARNING
he main electrical isolator should only be used in an emergency and for servicing.
It should never be used for closing down the burner, as this switches off the main fan prematurely
and may damage the heat exchanger, invalidating the warranty and causing a potential fire hazard.

2.2 Control Box - Oil Fired Heaters
High /Low oil burners although following the general sequence as described below also have extra functional stages
related to air damper positions. Refer to burner manufacturers instructions for further detail.
(See also the Burner Manufacturer's Instructions)
2.2.1
he oil fired burner fitted to the heater is controlled by a fully automatic control box and photoelectric flame monitor unit.
his control ensures the safe start, ignition and stop sequence and also monitors the safe presence of a flame.
If the flame should fail, or fail to be monitored, then the control will go to the safety shut down lockout condition. he
button on the front of the control box will light to indicate this. his button will then need to be pressed in manually to
reset the control box to recommence the burner firing cycle.
his is a thermal control which, following a lockout condition, cannot be reset until the thermal element has cooled. his
takes approximately one minute.
2.2.2 Operating Sequence
he operating sequence of the oil fired control boxes are as shown in Figure 2.1.
WARNING:
The control should not be reset from lockout more than three times without identifying and correcting the
cause. Residual fuel oil in a combustion chamber is an explosion risk.

Page 16
CABINET HEATER
2.2.3 Sequence of Events
he 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 12 seconds, the oil solenoid valve will open and the burner will fire.
After another 5 seconds the electric ignition is turned off and the burner will go to its normal run position.
he photo cell monitors the safe presence of the flame continuously.
When the temperature control is satisfied, the control box will turn off all its outputs simultaneously, and returns to the
rest position for the beginning of the next sequence.
2.2.4 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 control sequence see Fig. 2.1.
2.3 Control Box - Gas Fired Heaters
(See also the Burner Manufacturer's Instructions)
High /Low and Modulating burners although following the general sequence as described below also have extra functional
stages related to air damper positions. Refer to burner manufacturers instructions for further detail.
Ecoflam gas burner have only one pressure switch which is configured to cover both available combustion air and
reaction to increases in combustion chamber pressure.
2.3.1 Description of Gas Fired Heater Control Box
he gas fired burner fitted to all COMBA ® cabinet heaters is controlled by a full sequence plug-in control box. his
control ensures the safe start and stop sequence and also monitors the safe presence of a flame and burner air
pressure.
he Models 15 to 30 are wired for direct ignition of the main flame. All other models are wired for ignition of a start gas
flame as first stage and then the main gas flame as the second stage.
2.3.2 Sequence of Events
The operating sequence is as follows:
With the external controls on and calling for heat, and the air pressure switch at rest, (contacts n.c. closed), the burner
fan will switch on after a short wait for the control to "self check."
Note: If the air pressure switch contacts (n.c.) are open there will be no start.

Page 17
CABINET HEATER
Fig 2.2 Gas Fired Heater Control Box Sequen e
2.3.3 Air ressure Switch Contacts
he combustion air fan now turns on and the air pressure switch contacts (n.o.) have to close within the next 5
seconds to indicate the availability of sufficient combustion air or lockout will occur.
2.3.4 urge
he sequence continues with a purge time with the burner fan only running.
2.3.5 Electric Ignition ON
he electric ignition switches ON at the end of this purge time.
2.3.6 Start Gas Valve (Main gas for models 015 to 030)
he start gas valve opens and once a flame has been established this remains on until close down. he flame probe is
now continuously monitoring for the safe presence of flame.
2.3.7 Electric Ignition OFF
Five seconds later the electric ignition turns off, leaving the start gas flame to be proved as stable.

2.4 Honeywell Combination Fan/Limit Thermostat
his is a dual function control and safety device:
1. Fan Thermostat. his automatically turns the fan ON and OFF during the heater operation controlled by the
leaving air temperature. It is fitted with a white manual override button which must be in its pulled out position for
automatic operation. In its pushed in position the fan(s) will run continuously.
2. Limit Thermostat. his protects the heater from overheating caused by a reduction of air flow over the heat
exchanger. It is a manual reset device and once operated prevents the heater restarting until reset.
o reset wait until the heater has cooled sufficiently then press in and release the red reset button. After operation of the
limit thermostat, efforts should be made to locate the problem causing its operation.
Note: I IS ESSEN IAL HA HE LINK SHOWN IN FIG. 2.3 IS REMOVED IN HE EVEN OF A REPLACEMEN
COMBINA ION FAN/LIMI HERMOS A BEING FI ED
Following replacement or adjustment, the limit thermostat setting must be re-sealed using a suitable paint spot seal.
For settings see Commissioning Section 5.1.2.1.
Fig. 2.3 Combination Fan/Limit Thermostat
2.3.8 Main Gas Valve (For models above 030)
en seconds from when the start gas is energised the main gas valves energise and the main flame expands from the
start gas. he control is now in its normal run position.
When the external controls are satisfied the control box turns off all outputs simultaneously and returns to rest position
for the beginning of the next sequence.
2.3.9 Fault Conditions
If at any stage the flame fails , the air pressure switch detects a loss of air pressure or a rise in combustion chamber
pressure ,then the control will go to lockout. he red light on the control box will glow and the control will need to be
manually reset before any further start attempt can be made.
For control sequence see Fig. 2.2.
