Lighting
the
air
heater
VRC
‐
3
air
heaters
are
all
fitted
with
automatic
spark
ignition
systems.
When
adequate
airflow
for
combustion
is
proven
by
an
air
proving
control
and
a
pre
‐
purge
period
has
elapsed,
the
integral
ignitor
and
multi
‐
functional
gas
control
operate.
The
ignition
spark
ignites
the
gas
creating
the
burner
flame
which
is
detected
by
a
flame
rod
sensor.
If
a
burner
flame
is
not
detected,
the
ignition
controller
proceeds
to
lock
‐
out
and
requires
manually
resetting.
Lock
‐
out
is
indicated
by
the
red
warning
light
on
the
air
heater.
If
the
first
reset
is
not
successful,
wait
15
seconds
before
attempting
reset.
