Subject: GOLD Oil Boiler Primary Burner Controls #60200-02
In an effort to provide the industry with the best available technology for clean efficient
combustion of fuel oil, Weil-McLain has standardized the GOLD Oil boiler burner control offering
to include the Carlin 60200-02 primary control and 14,000 volt solid state ignitor. Listed below
are some helpful tips for understanding these new controls.
Carlin 60200-02 Primary Control Standard Features / Benefits:
♦ Interrupted Duty – Turns off the ignition ignitor once the flame is established reducing
energy consumption and minimizing component wear.
♦ Self-Diagnostic Check – On each call for heat, control performs a 4-second check of
internal circuitry. Helps prevent burner runaway in the event of a welded set of motor
contacts.
♦ 10 Second Valve-On-Delay (Prepurge) – Allows the burner motor and fuel oil pump to
come fully up to speed and pressure prior to opening the oil solenoid valve and igniting the
oil which provides cleaner startups.
♦ 10 Second Motor-Off-Delay (Postpurge) – Closes solenoid valve cutting off fuel supply
while keeping the motor and blower on to complete combustion process, virtually eliminating
smoke on shutdown.
♦ 15 Second Trial For Ignition – If oil fails to ignite in the first 15 seconds, control will lock out
reducing potential for oil soaked chambers.
♦ Flame Stabilization Period – Ignitor / spark remains on for 10 seconds after trial for ignition
period ends.
♦ Recycle – If control detects a flame failure, the burner will shut off in 1.3 seconds after loss
of flame and then automatically commence with a 65-second recycle period after which
control will go through another trial for ignition cycle.
♦ Latch up – If control sees 3 consecutive lock-outs on the same call for heat, control will
enter latch-up potentially eliminating flooded chambers from repeated homeowner attempts
of pushing reset button.
♦ Alarm Contacts – Close when control is in a lock-out or latch-up condition. Control may be
connected to a separate security system for notification of a no heat situation.
♦ Warranty – 3 years.
Primary Control Sequence of Operation:
1. Call for heat initiated.
2. Microprocessor performs a 4-second diagnostic self-check of internal control circuitry.
3. 1-second pre-ignition (ignitor energized with spark on).
4. 10-second valve-on-delay (prepurge).
5. Solenoid valve is energized allowing fuel to flow to nozzle and spark.
6. 15-second trial for ignition. If no flame is established, control will lock out after 15
seconds.
