Weil mclain boiler manual gold oil

Check for 24V output of transformer. Replace transformer if it is is receiving Vac, but not outputting 24Vac. Turn on service switch to power boiler.

Is there Volts at the service switch? Troubleshoot and correct the power supply to the senesce switch. Check for volts at the line voltage terminal block located inside the top left electrical compartment Correct wiring inside the control pod using the wiring diagram in this manual.

Inspect amp fuse. Replace the fuse with proper part. Nothing is shown on display screen, but boiler is operating Occurs when the communication is lost from the control module to the display.

Check for continuity on the wire harness from the display to the control module. Cycle power off and on using boiler power switch and check for operation. Replace with new display module. Automatically resets after 1 minute delay or using manual reset on display. Manual reset is necessary after 5 automatic resets have occurred during the same Priority heat demand. Reset using manual reset screen on display Verify water pipe is installed correctly.

Verify proper circulator and speed for boiler size and system requirements. Verify water pipe is installed correctly. Automatically resets when condition no longer exists. Verify proper flow direction of the boiler circulator. This circulator must be installed to push water through the boiler's return pipe. Verify proper boiler circulator speed setting in the control module.

Determine which sensors are suspect and measure their resistance value. If the resistance values are incorrect replace the temperature sensor.

If this are not being used they will always be shown as OPEN. This is normal unless the sensors were installed. Check wire harness for loose connections and pin engagement at sensor connection, chassis mount connection through control housing, and the control module.

Unplug connection at sensor and at control module and check continuity between ends. If problem persists after checking items above replace control module.

Refer to repair pans section for kit number. In addition inspect heat exchanger combustion chamber and flue ways for abnormal wear or buildup. Inspect vent system for abnormal wear or damage. Manual reset of control module if contacts are open longer than 5 seconds Check for low water condition in system. If low water condition does not exist, check Diagnostics - Inputs screen to view status of Low Water Cutoff. Check for a loose connection at the index plug on the control and connection on the back of the display.

Automatic external limit will reset 2. Manual limit fault must be reset by choosing Reset Lockout on the display. Is there an external safety device connected?

Also check for loose wiring connections. Remove the top right electrical cover and inspect the connector. The internal boiler circulator can be configured to turn on or off with DHW and heating zones. Refer to the control module Setup section to configure these properly for the system. Verify water pipe is installed correctly per instructions in this manual. Verify proper circulator sizing for boiler size and system requirements. Inspect flame and conduct combustion test. Force boiler into hi-fire.

Check flue gases with combustion analyzer and correct using the maintenance an startup procedure in this manual. Check for flame at burner via flame current with burner off.

Turn boiler off and watch flame through observation port. If flame continues after shutdown replace gas valve and venture. GASVALVE FAULT The control module has detected a problem with it gas valve output circuit Control will do automatic retry; lockout if retry unsuccessful; retry 1 hour after lockout — restart if condition cleared, but lockout permanently if condition still present.

Requires manual reset if control is in lockout Check wire harness connections between gas valve and control module. Check resistance between control and gas valve. If lockout reoccurs replace control module. Unplugging the low voltage blower wire harness will not allow or cause the boiler to rotate.

Reset using manual reset screen on display; control module will check again after 1 hour and will automatically restart if condition is corrected Check wire harness for loose connections and pin engagement at blower connections, chassis mount connection through control housing, and control module. Unplug connection at blower and at control module and check continuity between ends. Blower is connected to both low voltage and line voltage harness.

Check Diagnostics - Inputs screen with boiler in standby mode and blower not running. If blower does not rotate during ignition sequence check for V power at blower connection. If Vac power at blower motor and it doesn't start replace blower.

Check power at control module. If Vac is not present at control module when boiler is powered replace control module. Check condensate trap for blockage allowing condensate to accumulate inside heat exchanger.

Check ignition cable connection. Fouled, worn, bent, or faulty igniter. Fouled igniters can be cleaned for additional use with fine grit sand paper or steel wool. Worn or badly fouled igniters should be replaced with the proper repair part. Igniter rods should be parallel with a 35mm 0. Follow procedure in maintenance section of this manual to clean burner and heat exchanger using flue cleaning tool and rinse method.

Visual inspection of flue ways will often will not be able to diagnose condition. Check combustion settings on high and low fire and adjust per setup instructions if necessary.

Check incoming gas pressure with boiler off and at high fire. Adjust within limits on rating label. Verify correct boiler model is selected in control and high altitude is selected for installations ft above sea level.

Check ignition cable resistance. Skip to content. By entering your phone number and clicking the "Submit" button below, I agree to the following:.

If you have an electric water heater, turn off the power before removing the metal plate that houses the thermostat. Turn the knob on the side of the tank. Rotate the thermostat control. Generally, your boiler pressure should be between 1 and 2 bar. However, read your boiler's manual or ask your heating engineer for the required pressure for your particular model.

To check your boiler's pressure , you need to locate the pressure gauge on your boiler. Wipe down the exterior of the boiler with a damp cloth to remove any dust. Vacuum around the boiler to keep dust and lint from clogging the system.

Your room thermostat should be set to the lowest comfortable temperature , typically between 18 and 21 degrees. You don't need to turn your thermostat up when it is colder outside; the house will heat up to the set temperature regardless. If your boiler is on for a total of five hours per day , your daily usage should be around kWh. But if you've noticed an increase in your gas bill recently, your boiler could be using more gas than it should. How do you adjust the temperature on a Weil McLain boiler?
