Converting Blodgett 981 NG to LP: locating main burner orifice?

I am converting my Blodgett 981 commercial baking oven from NG to LP. I have the conversion kit, have swapped out the pilot orifice, installed the regulator and am stumped where to find the burner orifice to change it out. Can you give me a pointer where to find it? I can tear the whole burner out and break it down, but I'd prefer a ''surgical strike''.

Unless you are a qualified and certified gas tecnician, I DO NOT recommend attempting this yourself. Sorry.

Go to this site for an owners manual.
Please be alittle more specific.. Are you saying that the burners do not light? Is there a pilot?

SOURCE: The pilot lights go out on their own after awhile

yes this would definetly cause the pilots to go out and you should refer to your manual on changing between natural and lp gas on some units not only do you have to turn the gas regualtor and flip the small set screw to the oppisite side but most also require you to change the orifices of each burner if not then the stove will not light Ive gone through a similar situation with a viking best thing to do would be to get ahold of marcone appliance parts and have your model number as well as make of the machine handy and find out the prive of a gas-lp conversion kit. Please message me back if you have any further questions and please remember to rank how this opinion has helped in your appliance situation Thanks again

Convert lp natural gas

To convert a lincoln LP gas oven to a natural gas, you actually first of all need to buy from the supplier an orifice ment for natural gas and change. The difference in the orifices could be in the size of orifice aperture.
The orifice i'm talking about is located in the burner assembly. you got to dis assemble the burner so as to get to it.
After that you need to adjust the main gas manifold when the oven is on. The adjustment must be done such that the pilot flame is not yellowish

Changing your gas appliance from natural gas to LP or vice versa.

You have an LP gas stove which you really like and would like to take to a new home but the new home has a natural gas hookup. Since natural gas is already available it would be convenient to be able to use it. Can you convert your unit over to work on natural gas?

Yes it is possible to convert any LP gas appliance to natural gas or from natural gas to LP. The only difference is the size of the orifice used in the burner.

LP gas is composed of a much larger molecule than natural gas and requires a larger orifice to output the same amount of gas as a natural gas unit at the same setting. Therefore if you used an LP stove on natural gas it would produce too much heat and burn rather intensely. If you used a natural gas stove on LP it would not have much flame at all. You can see the problem. The solution is also obvious. You need the correct orifice.

Changing the orifice is easy. It is located in the middle of the burner and unscrews out of the unit. Install the new one the opposite way. Do not overtighten it.Usually the burners are made of soft metal and can strip easily.

The parts you would need are available at most good appliance stores but I would recommend the following site http://www.repairclinic.com . The parts will be cheaper at repairclinic. They have parts for almost any brand and a great search engine. They also have excellent videos showing how to make the repair.

Thanks for using FixYa and for the great rating.

I will soon need to convert a 1993(?) CALORIC Kitchen Range back to Natural Gas from LP. When I installed it, NG was not available, so the propane company guys converted it to LP. I was not here to learn...

First check the regulator valve on the back of the stove. Chances are it is a dual purpose valve and once you are ready to do the converstion.. you simply will move the lever or change the setting from LP to NAT.(obvisouly before proceeding you need to have the fuel supply turned off to the appliance)

Next check under the range lid or on the back of the stove for the spare NATural gas orifices.. when they changed it out for you there were two scenarios.. the range (most do) came with a set of LP orifices..and they simply changed these out on each burner supply including brolier/oven. (orifices are interchangeable nozzles that are threaded into the supply gas burner)

If they had to swap out the regulator chances are they would have given you the one that came with your stove.. However I am fairly sure the regulator is a dual purpose and you simply need to change the setting from LP to NAT.

DO NOT DO THIS WITHOUT CHANGING OUT THE ORIFICES FIRST.

If you cannot locate the spare orifices/spud/nozzles (they are called all of these) on the stove itself you will need to buy a set. A good appliance parts store will be able to help you with these.. again.. you will need one for each burner/burner supply.

If you can locate the range manual it will have instructions on how to do this.

Chances are your Natural Gas company will be able to help you with this.. especially if the regulator is dual purpose.. even if you can't find the orifices they are inexpensive.. fairly standard and easy to acquire. Usually just called a "conversion kit".. it will just consist of four or five small threaded 5/16 brass nozzles/orifices.
The installation is pretty straightforward. Again..a good appliance parts store may recommend a service company...and if your not familiar with diy repairs on a gas appliance.. a 50 to 100 dollar service call is well worth the money.

Best of luck to you!

Convert to lp gas

Hello,
You will need the owner's manual to follow their LP conversion instructions. You will need the make, model and serial # in order to buy the LP conversion kit (if needed) from a local appliance parts store or from the store where you bought the appliance. Typically, you will be either adjusting (turning down) or exchanging the main burner orifice(s), as well as adjusting the air shutter on the burner venturi tube, as needed for a bluer flame. The appliance regulator will need to be converted, which is usually done by flipping the cap. If you don't have your owner's manual, leave another comment for me with the model # and I'll see if I can find it online for you. I have not worked on this particular type of oven in my neck of the woods, but ovens are all pretty similar in design. Some also have a thermostat that needs to be converted by turning the Nat to LP selector behind the temp dial. Hope that helps. Douglas

Converting aan LP oven to gas

In most cases the pressure regulator has to be changed or adjusted. The orfices on each burner, oven, broiler and surface burner may need to be changed also. Sometimes they can be adjusted. Sometimes the threads on the pipe are different also. This is to prevent accidental connection to the wrong fuel. The big difference is the gas pressure. LP is usually around 10 - 12 lbs and natural gas is usually around 3 lbs. Properly adjusted you will like natural gas much better than LP as it is slightly hotter. The information will be in the instruction book and also on the Jenn air web site. Whirlpool owns both Maytag and Jenn aire so check all sites. The conversion kit is usually less than $50.
