COMMISSIONING,
LIGHTING
&
OPERATION
Final
testing
after
production
ensures
that,
if
the
installation
has
been
carried
out
strictly
in
accordance
with
this
document,
the
appliance
is
ready
to
be
taken
into
service.
11.1
LIGHTING
1.
Ensure
that
the
air
discharge
louvres
are
open.
2.
Turn
on
the
gas
supply.
3.
Switch
on
the
electrical
supply.
4.
Set
the
room
thermostat
to
‘ON’
position.
5.
If
the
indicator
light
on
the
burner
relay
glows
and/or
the
room
thermostat
display
flashes,
press
the
reset
button.
6.
The
burner
will
now
automatically
light
after
about
15
sec
and
within
60
sec
the
air
circulation
fan
will
run.
7.
If
the
installation
is
new,
3
start
‐
up
cycles
may
be
necessary
due
to
air
still
being
present
in
the
gas
pipe.
Should
the
air
heater
still
not
light,
refer
to
section
12
:
‘Fault
Finding’.
8.
The
gas
pressure
must
correspond
to
the
data
in
table
1.
If
the
gas
pressure
(G20)
is
higher
than
60mbar,
a
pressure
regulator
with
constant
terminal
pressure
must
be
installed.
If
the
gas
pressure
is
lower
than
20mbar/17.50mbar,
check
the
supply
pipework
to
ensure
it
is
correctly
sized.
11.2
OPERATION
Attention
During
start
up
all
gas
services
(up
to
the
gas
meter)
must
be
checked
again
for
gas
soundness
to
ensure
no
leaks
are
present.
The
condensation
drain
pipe
and
siphon,
both
already
filled
with
water,
must
be
visually
tested
for
water
tightness.
1.
If,
for
any
reason,
the
burner
flame
is
extinguished
during
a
run
cycle,
an
automatic
attempt
for
re
‐
ignition
will
take
place.
If
the
burner
does
not
relight,
safety
shut
down
and
lockout
will
occur.
Manual
intervention
to
reset
will
be
necessary
to
put
the
air
heater
back
into
service.
2.
In
the
event
of
overheating
for
any
reason,
overheat
controls
operate
to
switch
off
the
burner.
In
case
the
heat
exchanger’s
temperature
is
too
high,
the
burner
will
be
switched
off
by
the
LC1
limit
control
(first
safety).
The
burner
automatically
switches
on
again
after
cooling
down
and
re
‐
start
will
take
place.
The
limit
control
LC3,
which
operates
at
a
higher
temperature
setting,
switches
off
the
burner
and
itself
to
a
lockout
condition
requiring
a
thorough
check
of
the
heater
and
a
manual
reset
via
the
burner
relay
or
the
remote
control
to
restore
the
heater
to
operational
condition.
A
cooling
time
of
about
1
minute
is
necessary
before
resetting.
3.
When
the
set
temperature
has
been
reached,
the
comfort
regulation
ensures
modulation
on
the
burner.
To
compensate
possible
heat
losses,
warmth
is
still
dissipated
by
the
air
heater
itself.
4.
To
turn
off
the
air
heater
for
a
short
period,
turn
the
room
thermostat
to
a
lower
setting.
To
relight,
reset
the
thermostat.
5.
To
turn
off
the
heater
for
a
prolonged
period,
turn
the
room
thermostat
to
lowest
setting
and
turn
off
the
gas
supply
to
the
appliance.
Switch
off
electrical
supply
to
the
air
heater
only
after
the
air
circulation
fan
has
stopped.
To
relight,
follow
the
lighting
instructions.
6.
Gas
and
electricity
must
only
be
turned
off
in
case
of
emergency
or
for
prolonged
periods
of
shutdown
of
the
air
heater.
