Convert Weber Summit Barbecue Grill To LP or NG.

Convert a Weber Summit to Natural Gas or to Propane with orifices and a new regulator for the gas line. Although the Weber Summit models have existed for three decades and have gone through a lot of changes most of the Summit models through history all use the same small brass gas orifice. The Weber company does not publish item numbers so we check orifice diameters which does not make converting the gas type any more difficult. Changing a BBQ to NG or to LP by changing the orifice and the regulator and hose is still very simple.

Conversion Products Cannot Be Returned. Once the orifices are drilled, gas presure custom adjusted for a transaction, we do not have the ability to have them in our inventory. We set adjustments per order because our inventory are all blanks so Please make the correct measurements as described to select the correct orifices, hose, regulator or contact us for assistance. Conversion Parts are Customized To Order so regulators and Orifices Cannot Be Returned.

This image shows the tip of the control valve. The Weber stainless steel pipe burners have an air-adjustment sleeve at the front of each barbecue burner. The orifice at the tip of the control valve slides into the burner by sliding into the front, right through the air-adjustment shutter.

To convert to NG or to LP we need to remove the original brass orifice and replace the orifice with the exact same size of brass fitting but the hole drilled in the orifice determines the gas type and the BTU's.

Summit Flame Thrower Valve.
The flame thrower control valves used on the newer Weber Summit models integrates the ignition assembly into the control valve. Like a traditional control valve the gas orifice is mounted at the far tip of the valve where the Weber burner venturi slides onto the controls.

Remove the burner and then we can reach into the controls area from inside the grill to exchange the orifices and convert the barbecue.

Weber Tank Scale. The Weber tank scale supports the common 5 gallon (20 Lbs) LP cylinder. Inner gauge shows LP tank fill level. Although easily installed and convenient, the scale is considered Mandatory by Weber because immobilizing the LP cylinder in position is a prerequisite of the CSA safety certification and Residential UL Listing.

Denoting LP levels is convenient but the actual purpose of this scale is Safety and is Required for Weber to include on All LP models.

weber new summit model

Newer Weber Summit models come with hood handle mounted lights and a light design that also illuminates the control knobs. The igniters are flame thrower control valves with the ignition assembly built into the barbecue. We can convert the New Summit models by changing the orifice in the tip of every control valve.

weber summit orifice

Older Weber Summit Models were called Silver, Gold or Platinum to distinguish which materials were in the models. The features and the number of burners were also defined in the model by calling the barbevcue grill: B4 or C6 so we know which models had a smoker or a rotisserie or a side burner. The Summit in this image is already more than 10 years old and the design has changed several times. However, this old Summit and the newer Summit models still use the small orifice shown here.

Please Note Drilled Orifices Cannot Be Returned.

natural gas and propane orifice holes drilled

The difference between an orifice drilled for vaporized liquid propane and an orifice drilled for use in a natural gas appliance is very obvious when looked at side by side. The Summit orifice is only 1/4 inch across so the drilled natural gas opening looks tremendous.
