The rest of this blog post will expand on the process of removing and replacing Viking barbecue grill burners with step by step directions and images to show key points.

These are the burners coming out and being replaced with new stainless Viking burners.

This image shows the interior of the Viking gas grill with the old burners.  We have removed the cooking grates, warming rack and radiant shields to show only the burners.  Viking gas barbecue grills originally had the same heavy cast iron burners as  original DCS models but the stainless replacement burners of the newer models come with retro-fit kits to replace cast iron burner models.  Viking models are designed with center-fed U shaped burners and single pipe burners.  Obviously this model has one U burner and instead of a second U burner there are two of what Viking calls Smoker burners.  This model actually came with a smoker box wide enough to rest on top of the two pipe burners.

Viking single pipe burners are set to 15,000 BTU’s each so smoking has to be done carefully — if at all.  By comparison a Weber Summit model also has a single pipe burner installed below a smoker drawer but the Weber only has one smoker burner at 7,500 BTU’s.  Most Viking gas grill owners do not think of these burners as smoker burners designed for heating soaked wood chips only enough to keep them smoky but as two grill burners as the BTU certification implies.

In the back of the grill the center-fed U burners are installed with different hardware than the pipe burners.  The smoker pipe burners have a simple bracket mounted to the back fire wall allowing the burners to be mounted with a single screw and set level from back to front.  Removing the smoker pipe burners means unscrewing the mounting screw at the back of the burner which can be cumbersome after years of grease and fat and dirt built-up.  It is not uncommon to need to cut the screw heads or drill-out the screw through the mounting bracket.

In these images showing the burners being replaced we removed the installation screws from the two pipe burners and replaced them with new hardware so they could be seen a little better in these small images.

The center-fed U shaped burner also has a support bracket bolted to the back wall but the U shaped burner presses into a channel on the floor of the fire box so the tension of the clamp holds the burner solidly in place.  When removing and installing the U burners and the smoker burners it is not necessary to remove the protective shields bolted to the top of the burners.

While removing the pipe burners means unscrewing the back screws the U burner can simply be pulled up from the tension of the bracket.  Burners are removed by lifting the back of the burner while sliding the burner up and towards the back of the grill.  We lift from the back and slide the burner away because the front venturi tube of the burner is installed on the tip of the control valve inside the control panel.  The burner’s air shutter must slide off the orifice  straight, without lifting so we lift the back and slide the whole burner back..

When burners install we have to feel for the orifice, side slots and watch for the electrode sliding under the heat shield.

The venturi tube is the section of the burner where gas flows into the burner and is also where the carburetor is located.  On most barbecue burners the carburetor function is balanced by adjusting the air shutter at the tip of the venturi where the gas orifice is inserted into the burner tube.  The air shutter here can be adjusted to allow more or less oxygen to mix with gas as the gas flows into the burner.  Gas needs a mixture of oxygen in order to burn, and in order to burn clean the air shutter adjustment has to work together with the orifice and valve settings that control the flow of gas.

When we install new burners the first thing we do is slide the burner venturi tube through the hole inside the front firewall and guide the air shutter opening onto the gas orifice in the control panel.

In this image we are seeing as though inside the grill looking at the front firewall where the burner passes through the opening in the firewall and mounts onto the gas orifice at the tip of the Viking control valve.  As we can see here the gas orifice has a small hole drilled perfectly center n the hood-style orifice.  This small hole combined with the regulated gas pressure determines the maximum amount of gas flow, commonly referred to as “BTU”.

This image was shot from inside the control panel in order to see the exact same gas valve and orifice as the image on the right albeit from the opposite direction.  When the burner is installed the oxygen-adjusting shutter is mounted on to the gas orifice.  In most gas broilers, barbecues, grills, smokers, etc the control valve supports the burner in the control panel and keeps the burner perfectly level.  This is exactly how the Viking smoker burners are supported in the Viking gas grill models.  However, when removing and installing Viking U-shaped burners it is important to note the gas valve is not the sole support for the U burners.

Stainless burners are supported by front slots on front fire wall

As we can see in this top-view of the installed U burner the right and left sides of  the stainless U burner tubes are flattened into tabs that fit into slots in brackets bolted on either side of the opening in the firewall.  We can also see these same slots in the image above showing the orifice from inside the grill.  This image shows the newly installed burner so the center feed tube has disappeared through the firewall so the air adjustment can mount onto the valve orifice.  Also in this image we see the flattened tab and slot support.  In the center of the image the ignition tube is not clear but this stainless steel tube helps to ignite the burner if the electronic ignition is not functioning.  The stark white top left is the ignition electrode which also passes through the firewall just like the burner.

Installed the burner’s flat tips slide into slits for support. The ignition electrode mounts to fit just above the burner ports and below the protective shield.

Although showing the older burners, this picture is the same shot from the side in order to allow us again to identify the burner, installation support slot/tab, stainless steel manual ignition tube and in the foreground is the white porcelain of the electronic ignitor electrode.  Older Viking electrodes were not made so well but for almost a decade these ignition electrodes are thick and heavy, double-post electrodes like the igniters originally designed by Thermal Engineering for use in the new infrared burner.  The ignition electrode design matches the burner by extending the spark to below the grease shields bolted to the burners.

In Summation:

Viking burners can be easily and quickly replaced.   Lift from the burner from the back and slide away because the front if the burner is mounted on the control valve orifice.  Install the new burner by first installing the air adaptor onto the control valve orifice which is inside the control panel.  Because we cannot see the control valve when mounting the burner this is a lot easier to do with the control panel removed which allows us to grab the burner venturi and guide the air-shutter onto the orifice.  When I cannot see if the burner is over the orifice I will wiggle the burner back and forth knowing that once the burner is on the valve it will barely wiggle at all because the orifice is in the burner tube.  The burner has to be mounted in the back of the grill exactly level so gas does not leak in the control panel so we have to understand how the burner mounts.  The U shaped Viking burner needs to press down to click into the U channel on the floor and the smoker pipe burner rests on a small shelf where a screw holds it perfectly in place.

Once the burners are installed test the flame pattern and make any adjustments to the control valve and air-adjustment so the burners function properly.
