Dacor Gas Range LP Conversion Instructions

This guide provides instructions for converting Dacor gas ranges, models DOP48*96*G*, from natural gas to LP (propane) gas. It is crucial that this conversion is performed by a qualified installer or gas supplier following these instructions and all applicable codes.

Safety Warnings

WARNING: Failure to follow all instructions could result in serious injury or property damage. Ensure you know the location of the gas shut-off valve and how to operate it. Disconnect electrical power before servicing. Improper orifice placement can lead to dangerous operating conditions, poor cooking results, high flames, and toxic fumes.

LP Conversion Kit

The ranges are shipped with LP Conversion Kits containing properly sized burner orifices for surface and oven burners. These are typically found in a plastic bag with the user manual.

Burner Orifice Sizes and Output Ratings

The document includes detailed tables specifying orifice sizes and BTU/h ratings for various burner locations for both LP Gas (Propane) and Natural Gas. Orifice markings (e.g., 115 for 1.15 mm, 180 for 1.80 mm) are provided for identification.

Required Tools

• Adjustable wrench
• 1/2’’ open-end wrench
• Phillips screwdriver
• Small flat-bladed jeweler's screwdriver
• Flat-bladed jeweler's screwdriver
• 7/16” or 11 mm nut drivers
• 9/32” or 7 mm nut drivers

Conversion Procedure

Converting the Pressure Regulator

1. Disconnect electrical power and shut off the gas supply.
2. Locate the pressure regulator at the back of the range.
3. Using a flat screwdriver, remove the dual-purpose orifice counter-clockwise.
4. Reinstall the orifice with the LP gas end exposed, turning clockwise.
5. Ensure the oven shut-off lever on the regulator is in the open position.

Converting the Surface Burners

1. Remove burner caps and heads from the manifold cups.
2. Using a 9/32” or 7 mm nut driver, remove the existing burner orifice from each manifold cup.
3. Identify and install the correct LP conversion orifices for each surface burner.
4. Tighten the new orifices with the appropriate nut driver.

Converting the Oven Burners

The process involves removing oven components like the cavity floor, bake-spreader bracket, and burner assemblies to access and replace the orifices for both bake and broil burners.

• Bake Burners: Remove screws securing the cavity floor and bake-spreader bracket. Lift out the bake burner and replace the orifice using a 9/32” or 7 mm nut driver.
• Broil Burners: Remove screws securing the HSI wire bracket and broil burner bracket. Carefully tilt and pull the broil burner to access and replace the orifice using a 7/16” or 11 mm socket wrench.
• Infra-red Burners: Remove screws, tilt the burner, and pull to remove. Replace the gas nozzle with a 7/16” or 11 mm socket wrench. Reassemble by tilting and pushing the burner back into place.

Adjusting Flame Settings

Adjusting Low Flame Settings on Cooktop Burners

1. Turn on two or more surface burners to MED-HI.
2. Quickly turn one control knob to the lowest setting. The flame should remain lit.
3. If the flame flickers or goes out, adjust the bypass valve screw on the control valve stem using a small flat-bladed screwdriver. Turn counter-clockwise to increase flame size.
4. Replace the control knob and recheck the low flame setting. Repeat for all surface burners.
5. Perform an additional low flame check by quickly opening the oven door while a cooktop burner is on LO. The flame should remain stable.

Adjusting the Air Shutter Settings on the Oven Burners

1. Reinstall the oven door, ensuring hinge arms are properly seated and locked.
2. Open the gas shut-off valve and restore electrical power.
3. Select Bake or Broil mode on the oven display and press START.
4. Observe the flames: Yellow flames indicate the air shutter needs to be opened further (clockwise). Flickering or blown-out flames indicate the air shutter needs to be closed further (counter-clockwise).
5. Retighten the locking screw after adjusting the air shutters.
6. Check the flame size: The inner cone should be approximately 1/2” to 3/4” long.
7. Flame Quality: Soft blue flames are normal for natural gas. Yellow tips are normal for LP gas. Yellow flames indicate abnormal operation requiring further adjustment.
