For oil-fired Crown Boilers, locate the reset button on the burner unit and press it to activate the ignition sequence. The burner motor should start, and you should hear the oil pump and ignition system working. If the burner does not ignite within a minute, press the reset button again. If the burner still does not ignite, consult a professional technician for further assistance. By following these steps and adhering to safety guidelines, you can successfully light your Crown Boiler and enjoy efficient heating in your home or building.

Step by Step Guide on How to Light a Crown Boiler

Step1: Locate the Gas Valve Handle.

It is usually on the front of the boiler. The knob will be in the “OFF” position and must be turned to the “ON” position. The pilot light should now be lit. If it is not, follow the manufacturer’s instructions for relighting the pilot light.

Step 2: Turn on the Main Power Switch.

The switch is usually located near the gas valve handle. Once you have turned on the main power, you will see a green light come on, knowing that the power is now running to the unit. If there is no green light, check your breaker box to make sure that the power is on and that the breaker for the boiler has not been tripped.

Turn on Main Power

Step 3: Prime the Pump.

The pump is located on the side of the boiler. There is a knob or lever that you can turn to prime the pump. Once you turn the knob or lever, water will start flowing through the pump. This is normal. Continue priming the pump until water starts coming out of the bleed valve.

Step 4: Open the Water Feed Valve.

The water feed valve is a knob near the bottom of the boiler. You turn it slowly to open the valve and let water into the boiler. You may need to open the valve all the way to get water flowing into the boiler. If you have a Crown boiler with an automatic water feeder, the water feeder will open the water feed valve for you.

Step 5: Push and Hold the Reset Button.

The reset button is a button near the main power switch that you have to hold down for a minute before releasing. If the boiler doesn’t reset, you might need to look in the owner’s manual for more directions.

Step 6: Check the Water Pressure.

Once the boiler has started up, check the water pressure gauge to make sure that it is reading between 12 and 15 psi. If the pressure is too low, you will need to bleed the air out of the system.

To do this, locate the bleeder valve on one of the radiators and open it until water starts to come out. Once water is coming out steadily, close the valve and check the pressure gauge again. If the pressure is still too low, repeat this process until the desired pressure is reached.

Locate the Bleeder Valve

Step 7: Set the Thermostat.

Once the boiler is up and running, you will need to set the thermostat to your desired temperature. The thermostat controls the boiler’s heating cycle, so it’s important to set it to a comfortable level. You can find the thermostat on the side of the boiler unit.

To sum it up, lighting a Crown Boiler is easy as long as you follow the proper steps. First, make sure that all the power switches are turned off. Then, open the boiler’s door and remove the burner assembly.

Next, clean out the burner area and add the proper amount of fuel. After that, reattach the burner assembly and turn on the power switches. Finally, set the thermostat to your desired temperature. By following these steps, you’ll be able to enjoy a warm and comfortable home

Step 8: Check the Water Level.

It is important to check the water level in the boiler on a regular basis. The water level should be between 1/2 and 2/3 full. If the water level is too low, it can cause the boiler to overheat and shut down. On the other hand, if the water level is too high, it can cause the boiler to operate inefficiently.

To check the water level, simply look at the sight glass on the side of the boiler. If the water level is too low, add more water until it reaches the proper level.

Check the Water Level

Step 9: Adjust the Air Damper.

The air damper is a lever on the front of the boiler that controls the amount of air that is allowed into the combustion chamber. If the air damper is set too low, it can cause the boiler to overheat and shut down. On the other hand, if the air damper is set too high, it can cause the boiler to run inefficiently and use more fuel than necessary.

To adjust the air damper, first, locate the lever on the front of the boiler. Then, turn the lever to the left to decrease the amount of air entering the combustion chamber. Next, turn the lever to the right to increase the amount of air entering the combustion chamber.

Step 10: Check the Pressure Gauge

The pressure gauge is located on the front of the boiler, just below the air damper lever. The pressure gauge shows the amount of pressure inside the boiler. If the pressure is too high, it can cause the boiler to overheat and shut down. If the pressure is too low, the boiler will not be able to generate enough heat.

To check the pressure gauge:

  1. Set the mode switch to the “Off” position.
  2. Wait for the boiler to cool down. The boiler must be cool before you can open the pressure relief valve.
  3. Open the pressure relief valve. The pressure relief valve is located on the top of the boiler, just to the right of the mode switch.
  4. Place a bucket under the pressure relief valve to catch any water that may be released when you open the valve.
  5. Slowly turn the pressure relief valve counterclockwise until water begins to flow from the valve.
  6. Allow the water to flow until it is clear. You may need to wait a few minutes for the water to become clear.
  7. Close the pressure relief valve by turning it clockwise. Ensure that the valve is closed tightly so that no water can escape.
  8. Set the mode switch to the “On” position.
  9. Check the pressure gauge. The pressure should be between 12 and 15 psi. If the pressure is not within this range, you will need to adjust the pressure relief valve.
  10. If the pressure is too high, turn the pressure relief valve clockwise until the needle on the pressure gauge is in the 12-15 psi range.
