Beckett 7590 Gas Power Burner Control - Manual (Page 8)

8
Fire or Explosion
Hazard
Can cause severe injury, death,
or property damage.
Replacement control must be configured
to match all timings, settings, and pre-
purge of the control being replaced.
• DO NOT USE A TRIAL FOR
IGNITION TIMING LONGER
THAN THE TIMING ON THE
ORIGINAL CONTROL. Severe
injury, death, or substantial
property damage could result from
a longer trial for ignition timing.
• MATCH THE LOCKOUT LOGIC
SEQUENCE TO THE ORIGINAL
CONTROL. If the original control
is a single trial for ignition or
allows three trials for ignition
before lockout, the replacement
control must match the number of
ignition trials.
Operation
7590T
The 7590T may replace some existing burner
controls designed for 24 volt gas valves. The
7590T cannot be used to replace controls
designed for use with line voltage (120 Vac)
gas valves or controls with pressure switch
connections. Settings are locked after 4
hours of burner operation.
Status & Diagnostics
The 7590 module has 3 LED lights
Wiring must comply with all national and
local codes. Wiring must follow appliance
and burner manufacturer’s instructions.
Follow the appropriate hook up drawing
for the application in which the control is
being installed.
The ignition cable length
should be 3 feet or less,
or meet igniter manufacturer’s specified
length. Avoid placing the ignition cable in
direct contact with metal surfaces as
reduced spark voltage could result. Use
plastic or ceramic standoffs if necessary.
The control, electrode
and flame sensor must
have a common ground with the main
burner for proper operation. Failure to
provide proper ground for the control,
electrode and sensor may result in a failure
to sense the presence of flame. Failure to
sense flame will result in lockout or
continued cycling of the ignition sequence.
On models with Air
Pressure Switch
terminals (7590C, D), do not place a
jumper on the Air Pressure Switch
terminals. Placing a jumper on the
terminals will cause the control to lockout.
The Air Pressure Switch must be in place
for the control to operate properly
Frozen Plumbing
and Water
Damage Hazard
If the residence is unattended in
severely cold weather, burner primary
control safety lockout, heating system
component failures, power outages or
other electrical system failures could
result in frozen plumbing and water
damage in a matter of hours.
For protection, take preventive actions
such as having a security system installed
that operates during power outages,
senses low temperature and initiates an
effective action. Consult with your heating
contractor or a home security agency.
Fire or Explosion
Hazard
Can cause severe injury, death,
or property damage.
USE 7590 GAS BURNER CONTROL ONLY
WITH BECKETT 7474001 GAS IGNITER.
Use with other igniters could result in
allowing gas flow when flame is not
present.
