USER INSTRUCTIONS PublicationNo. ZZ1091/2
April 2002
MODULATING CONTROL- HOW IT WORKS
Modulating Control automatically operates your heating system to maintain winter comfort efficiently and
unobtrusively.
You select the comfort level by setting the temperature controller (called the Thermista-stat).
The amount of heat needed depends upon the
difference between the temperature outside the dwelling and your chosen comfort level. The system
automatically adjusts its warm air output to achieve this level.
Examples:
When full heat is needed (during very cold weather, or on initial warm up), the gas burner operates at
full output and the fan runs at maximum speed until the room temperature, determined by the Thermista-
stat setting is reached.
The gas burner will then operate in short firing cycles with the fan running at a reduced speed.
In the event of this appliance being sold or transferred
to anotheruser, THESE instructions must be supplied.
Johnson and Starley prides itself on its ability to supply spare parts quickly and efficiently. If your service engineer indicates a
problem in obtaining a spare part, advise him to contact Johnson and Starley Spares Department at the address below.

1. TOLIGHTYOURHEATER
1.1 Ensure that the gas supply to the heater is turned on.
1.2 Set both the “AIR HEATER” and “WATER HEATER”
(if fitted) switches on the time control to the “OFF”
position.
1.3 Turn the Thermista-stat (room temperature control) to
position “9” (see fig. 1).
1.4 Switch on the electrical supply to the heater.
1.5 Set the “AIR HEATER” switch on the time control to
“CONT”After a period of 15-20 seconds the burner
will ignite automatically, indicated by the green LED
light marked ‘ON’ on the indicator panel (see Fig. 2).
Shortly afterwards the air circulation fan will start.
1.6 Adjust the Thermista-stat to the desired setting (see
Section 3).
1.7 The heater will now operate automatically under
thermostatic control.
1.8 If the burner does not ignite the first time, the red
LEDlightmarked‘LOCKOUT’willlight.Ifthis
should occur, check that the gas supply to the
appliance is turned on, wait approximately 10
seconds and then press the button marked ‘RESET’
to re-initiate the ignition sequence.
1.9 If, after carrying out the above instructions several
times, the green light fails to remain lit, contact your
local service engineer.
2. TOSTOPYOURHEATER
2.1 For short periods, e.g. weekends:
Turn the “AIR HEATER” switch to the “OFF”
position, or turn the thermista-stat anticlockwise to
to its minimum setting. This will cause the burner to
extinguish and the heater fan to stop once the heat
exchanger has cooled. When you require the heating
on again, turn to “AIR HEATER” switch to the “ON”
position, or reset the thermista-stat to the desired
setting.
2.2 For longer periods, e.g. a week or summer
shutdown:
Turn the “AIR HEATER” switch to the “OFF”
position, set the Thermista-stat to its minimum
setting, then turn off the electricity supply to the
heater.
WARNING: Do not turn off the electrical
supply when the main burner is lit, as this may
cause damage to the heater.
2.3 IMPORTANT: If summer air circulation is re-
quired, the electrical supply to the heater must
remain on.
3. TEMPERATURECONTROL
3.1 The figures on the thermista-stat dial represent levels
of warmth and when you select a dial number, the
heater will operate automatically to maintain that
level. You will soon find the setting at which you are
most comfortable, but we recommend that you start
at setting 5 and make adjustments up or down until a
satisfactory level is reached.
4.1 You can control the heat to each room by opening
and closing the warm air outlets, but never close
more than half of the outlets at any one time or the
performance of the heating system will be affected.
Warm air outlets in the room where the thermista-stat
is sited should always be open to ensure that the
heating system is controlled properly.
4.2 During the average winter weather, warm air outlets in
rooms not having a thermista-stat should be opened
only as much as is necessary to bring the room to a
comfortable level.
4.3 Overnight in prolonged severe weather, it is better to
set the heater time control to “CONT” and reduce the
setting of the Thermista-stat to provide a general
background heating (i.e. Setting 4). On rising, reset
the Thermista-stat to the normal daily comfort setting
and the room temperature will quickly rise.
4.4 SUMMERAIR CIRCULATION
During hot weather, unheated air can be circulated
around the dwelling, (using the air circulation fan),
by turning the Thermista-stat fully clockwise to the
switched‘SUMMERAIRFLOW’position.
IMPORTANT: If at any time the heater fails to
turn off when there is no demand for heat,
switch off the gas and electrical supply to the
heaterand contact your local service engineer.
5. TIMECONTROLOPERATION
It is worth noting that best economy is achieved at
the lowest setting that you find acceptable.
4. CONTROLOFYOUR HEATINGSYSTEM
5.1 In addition to continuous operation, the Time Control
will provide 24 hour timed operation of the air heater
in 15 minutes increments (1 tappet). “On” periods are
set by moving the required number of tappets in
towards the centre of the dial. For example, a 4 hour
“on” period will require 16 tappets set to the “on”
position at the required time.
6. AIRFILTER
6.1 The air filter is located where the return air ducting
connects to the air heater.
6.2 IMPORTANT: during periods where the heater is
being used constantly, the air filter should be
checked at regular intervals.
6.3 TOCLEANTHEFILTER: cleaningthefilterwill
depend on the filter type. It will be either:
a) PassiveFilter: withdraw the filter from the heater,
clean with a soft brush or vacuum cleaner and refit.
b) Electronic Filter: withdraw the filter as above and
remove surface dust with a soft brush. If the filter
medium is soiled, replace as directed in the filter kit
instructions. DO NOTATTEMPT TO CLEAN OR
WASHTHE FILTERMEDIUM!
NOTE:if you allow the filter to become clogged the
heater effeciency will be greatly reduced.
INNEW DWELLINGS: cleanthefilter onceaweek
for the first month or two to clear builder’s dust.
7. MAINTENANCE
7.1 It is recommended that a full maintenance check on
your appliance be made at least once a year and that
a service contract is taken out at the end of the
guarantee period.Your local gas supplier will be able
to provide details of arrangements for this service.
Note:This appliance SHOULDbe checked and
maintained periodically by aqualifiedprofessional
orcompetentperson.
8. POWER CUTS
8.1 If you experience an electrical power cut your air
heater will cease to operate. When the electrical
supply is restored, the heater will work normally but
the Time Control WILL require resetting.
9. TROUBLESHOOTING
9.1 Check that the Thermista-stat and Time Control are
set correctly to your requirements and that at least
half of the warm air outlets are open, especially in the
room where the Thermista-stat is located.
9.2 Check that the air filter is not clogged, if so clean as
detailed in Section 6.
9.3 If the LOCKOUTis lit, waitforapproximately 10
seconds and then press the RESET button.
9.4 If the heater will still not operate correctly, contact
your local service engineer.
Servicearrangements:
a. for new dwellings, servicing is usually supplied
for a specific period under arrangements made
by the building contractor.
b. localAuthorities often have their own special
arrangements.
c. if the above do not apply, contact your local
service engineer, or the Service department at
Johnson & Starley Ltd.
10. IFYOU SMELLGAS
DO NOT operate any electrical switches, or use
a naked flame.
TURN OFF the gas supply.
VENTILATE the area by opening doors and
windows.
CALLOUT your local gas supplier.
11. CLEANING

a mild soap solution. DO NOT use abrasive pads or
scourers.
