General
IMPORTANT The heater primary contains Senti-
nel X100 inhibitor. The minimum water should be
released during filling to maintain its concentra-
tion.
The elimination of air from the heat exchanger is
essential to maximise the life of the Heater.
It is strongly recommended that the Heater is first run
with the
GAS OFF
until the air has been purged.
If air has not been released then there is a possiblity
of the Heater overheating and triggering one of its
safety thermostats. An Air Vent is provided on the
top of the Heat Exchanger
(See Fig 8.0)
to assist its
removal.
It is opened and closed by rotating the front
connector. A second is a standard radiator vent in
the righthand Side Panel.
The internal pump can be run by using the Pool
Thermostat in the ‘P’ position.
(See Fig 8.1)
to aid
de-aerating, this also opens the 3 Port Valve to
utilise the heating system
.
If this is not yet plumbed
and the connections have been sealed, temporarily
remove the brown wire to the 3 Port Valve at its 6 way
terminal strip on the Electrical Chassis. Reconnect
when re-commissioning with the heating circuit.
It requires that the Mains in connected and that there
is a live on Pool demand, the Pool Pump need not be.

The Heater Control is factory set to display in Fahren-
heit and work to a maximum temperature of 90°F
(32°C). If a Centigrade display or higher temperature
106°F (41°C) maximum is required, this can be
changed in the User Setup Mode.
(See Page 17)
The boiler is factory set for Natural Gas, fitted with
automatic ignition and will start when the gas cock is
open, mains is connected and the Pressure Switch is
activated by the pool pump. (for greater detail about
the internal controls see the Maintenance section,
Fault Diagnosis)
LPG models require to be modified as described on
page 13.
It is recommended that the condensate trap is full of
water before firing.
If the Heater fails to light the gas it will shutdown
and try again. It will repeat this a total of 5 times and
then lock out. This will show as the
Red
LED lit and
‘GAS’
on the display. Press the Lock/Reset button
to start another 5 attempts.
It is possible with the front door off to see when the
burner is lit through the sight glass.
(See Fig. 8.2)
After the burner has been lit for a few minutes the
gas rate and combustion should be checked, see
the
Technical Data on Inside Cover
for details.
The Heater is factory set and should not require
adjustment. When the Heater has been running for
at least 10 minutes check all joints, gas and water,
for leaks, and correct where necessary.
When running satisfactorily, complete the commis-
sioning details on the inside back page of these
instructions.
Note:
The boiler is fitted with a syphon trap that in-
cludes a blocked drain detection device. This is to safe-
guard the boiler from a blockage or the possible freez-
ing of the condensate pipework in extreme weather.
Should this happen the control will lockout and the
display will show ‘
HI
’, as in “condensate level is high”.
See the Fault Finding section for more details.
This will have to be corrected before the Heater will run.
The user should be made aware of this feature and,
that in the event of blocked or frozen condensate
pipework, the boiler will automatically stop functioning.
It will start again as soon as the blockage has cleared.
Finally, instruct the user on Heaters operation and con-
trols.
Commissioning - Heating
First commission the Heater for Pool use.
As supplied the Heater is set to provide its minimum
output to heating, about 6 kW. This can be increased
but not decreased.
To increase access the controls Service Mode
(See
Page 23)
and alter the
Heating Input Maximum
from its starting point of 0% to the required level.
(See Fig 8.3).
It is not recommended that this is
increased above 50% as the Heater operates as
either as a Pool Heater or a Heating boilers, but not
both at the same time.
The priority of Pool or Heating, which is satisfied
first, can be set in Service Mode
(See Page 23).
A four minute anti-short cycling delay operates on
the Heating thermostat, it can be reset to zero by
altering the Heating Temperature Control Knob.
