A supply house such as johnstone. Take all information of the furnace and old orifice with you and show them what you need.
For a Miller Nor-dyne 62000 BTU natural gas furnace, the orifice size typically needed is 0.125 inches (or 1/8 inch). However, it's essential to verify this with the manufacturer's specifications or installation manual, as orifice sizes can vary based on specific models and gas pressures. Always consult the furnace's documentation or a qualified technician for accurate guidance.
its in the pilot lamp.. you need to slide the orifice out of there to clean or replace every so often
The furnace pilot light may not be working due to issues such as a clogged pilot orifice, a faulty thermocouple, or a gas supply problem. It is important to troubleshoot and address these issues promptly to ensure the furnace functions properly.
The pilot light on a furnace may keep going out due to issues with the thermocouple, a dirty or clogged pilot light orifice, a faulty gas valve, or insufficient gas flow. Regular maintenance and cleaning can help prevent this issue.
For a 100,000 BTU four-burner furnace, the LP (liquefied propane) orifice size typically ranges from .050 to .070 inches in diameter, depending on the specific furnace design and manufacturer specifications. It's crucial to consult the manufacturer's guidelines for the exact orifice size required, as factors like elevation and specific gas pressures can affect the optimal size. Proper sizing is essential for efficient operation and safety.
The manifold if the metal tube that directs the gas from the gas valve to (2-10) orifices so each orifice receives the same amount of pressure. This manifold is factory made and should never be changed.
Remove the pilot assembly from the furnace and clean it up. You need to be careful when putting it back on at the gas valve so as not to crossthread the screw. Take a thin wire and clean the pilot orifice, then use a brush or sandpaper on the thermocouple.
Several factors can cause a furnace's pilot light to go out, such as a malfunctioning thermocouple, a dirty pilot light orifice, a draft in the area, or a gas supply issue. It is important to address the underlying cause promptly to ensure the furnace operates safely and efficiently.
an electric furnace runs off of 208/230 Volts while a typical gas furnace runs off of 120 also a gas furnace will have a valve for the gas relay where the gas enters the furnace.
Yellow flames from a natural gas furnace indicate that the combustion ratio is off and you have too much excess air in the mixture, if the discolored flame is isolated in the burner meaning on only 1 out of 3 or more then the burner/orifice may be out of alignment or there maybe a crack in the exchangers cell.
Defective thermocouple or possibly a dirty or clogged pilot orifice.
