Arrow Natural Gas To Propane Fuel Conversion

Hello gosserwb. Welcome to the Gas Appliances topic.
Lots to read and comprehend below. Proceed slowly.

Propane Gas Orifice Sizing Here:
http://energy.growmark.com/propane/C...e%20Capacities

If the stove is currently set up to burn natural gas and currently connected to propane, the burners would burn very large, appear or actually burn yellow, because the burner orifices holes are too large. Natural gas orifices have holes sized for natural gas, which are too large for propane fuel.

To convert the stove to propane, the orifices must be either replaced or turned in wards to reduce the hole size. In some cases the orifices can be screwed opened or closed to adjust the burners flame size but not always. Some orifices are non adjustable. They turn but do nothing. In those cases, orifice replacements are needed.

On most older stoves the orifices are adjustable while on some they still are not adjustable. The orifices are the brass or bronze hex nuts onto which the burner tubes are set. There is also adjustable air shutters on each burner tube at all the burners.

To make the conversion where orifice replacement is required, the first thing you have to know is what the burners are rated at. Inside or on the stove somewhere is a plate containing all the required information. Once you have this information, write down the stoves information and visit the local retail appliance parts store for replacement parts. The appliance stores counter service person will be able to determine orifice sizes required.

Another item that will need attention, is the gas regulator. This part is located where the incoming fuel line is connected to the appliance. If the existing regulator isn't convertible between natural gas and propane, the part will also need to be replaced. Failure to convert or replace the regulator for the type of gas used will create burner operational problem, etc.

Another item that has to be set correctly is the ovens pilot flame, if it has a pilot flame. Most of those with pilots have a set screw on the body of the thermostat near the stem behind the temp knob. The screw will be labled...N or Nat for natural gas. P or LP for propane. Turn the set screw to the type of fuel used.

Suggestions:
Read the manufacturers online web site for product information, problem possibilities, causes and solving methods, part locations, disassembly, reassembly methods, repair procedures and instructions, fuel type conversions, pictorials and schematics, which may be available online.

An excellent source for original replacement parts is your local retail appliance parts store. Appliance parts dealers carry replacement parts for all appliances. Parts dealers are listed in the phone book under appliances.

Oven burner and/or broiler burner adjustment:
Flames should be not more than one inch from the outer edges of the flame spreader. The flame spreader is the flat plate the sets on top of the burner tube. Adjust the orifice in wards or out wards until the flame tips are about 1 and 1/2 inches to 2 inches in wards from the outer edges of flame spreader is ideal.

If the flames appear yellow or have yellowed tips, adjust the air shutter on the burner just above the orifice to allow slightly more air to enter. But not so much to cause flames to lift off of the burner and blow out wards with force.

There should be 2 markings on the valve body indicating each of the fuel positions. LP for propane and NAT for natural. There may also be a tiny lever or set screw on the thermostat control valve. This valve will be behind the thermostats temperature knob.

To gain access to it, remove the thermostats temperature knob by pulling it forward. Then look behind the knob for either of the two conversion markings. Set the slotted set screw to the correct fuel type.

If screwing down the oven/broiler orifice did not control the size of the burner flames, that orifice is not likely to be an adjustable one. Here is a means to determine if that orifice is or is not adjustable. The burner needs to be removed from the gas control valve. The burners tube ending sits on the gas valve.

The other end of the burner is secured to the front of the oven. Rests on a ledge or lip at the base of the access door. There will be a cotton pin OR a screw securing it. Whichever it is, remove it. Than remove the burner by lifting it up and off the gas valve at the back of the oven/broiler area. Once removed, that brass or bronze hex nut thimble looking part is the orifice.

Unscrew it off the gas valve and remove it. Stick into the gas valve should be a pointed raised sphere like part. If one is there, the orifice is adjustable. If none is there, the orifice is not adjustable. In this instance, the orifice needs to be replaced with an LP orifice. Note the BTU rating for that specific burner on the rate plate.

At any local appliance parts store, a replacement orifice for an oven and/or broiler or both can be obtained for that BTU rating in the size for propane fuel. Appliance parts dealers are listed in the phone book.

Once obtained, install that "LP" orifice as the other one was. Reinstall burner exactly as it was found prior to removal. Turn new orifice opened about 6 full turns from the lightly seated and closed position.

Relight pilot. Test burner flame size. Flames should not exceed flame spreader plate which is on top of burner attached with a wing nut. Flames should be not more than one inch from the outer edges of the flame spreader. In wards 1 and 1/2 inches to 2 inches in wards from the outer edges of flame spreader is ideal.

If the flames appear yellow or have yellowed tips, adjust the air shutter on the burner just above the orifice to allow slightly more air to enter. But not so much to cause flames to lift off of the burner and blow out wards with force. Once correct orifice opening is set and the air shutter is set....your set...job done...

Kindly use the reply button to post all replies, add additional information or ask additional questions when replies are posted. Using this method moves and/or keeps the topic back up to the top of the list of questions automatically and keeps all content on the same subject within one thread.

Retail appliance parts dealers can also help. They will need the make, model and serial numbers. Appliance parts dealers are an excellent source for original replacement parts and problem resolving matters. Dealers are listed in the phone book under appliances.

Be sure the electrical power to the appliance is turned off, before attempting any repairs or services. Always check for gas leaks whenever moving the appliance and/or a service or repair includes any connection of a gas part.
