To check the manifold gas pressure, remove the burner cap and connect a manometer
(water gauge) or other pressure test device to the burner orifice. Use a rubber hose
with inside diameter of approximately ¼” hold the end of the tube tight over the
orifice. Turn the gas valve on. For a more accurate pressure check, have at least two
(2) other top burners burning. Be sure that the gas supply (inlet) pressure is at least
one inch above the specified manifold pressure. Maximum gas supply pressure must
not exceed 14” inch water column, minimum gas supply pressure must be 1” inch water
column above recommended pressure, 12” for propane gas, and 5” water column for
natural gas. When properly adjusted the manifold water column pressure is 11” for LP/
propane gas or 4” for natural gas.
NOTE: There is no adjustment for the pilot
flame, you must use the NG pilot orifice
included in the conversion kit and this will
ensure the pilot flame is the correct size
(see image).
NOTE: Once the unit has been converted
fill out the included sticker and place it on
the back of the range, beside the rating
plate (see image).
Once you have completed the conversion, check
the operations of ignition making sure each of
the 4 burners, pilot flame and oven burner flame
are functioning correctly. Please refer to pages 28
through 30 – Operation of Range.
High Altitude Applications above 2,000 feet: At
elevations above 2,000 feet, the range must be
derated 4% for each 1,000 foot above sea level.
It is the installer’s responsibility to see that the
ranges input rate is adjusted properly.
