To check the manifold gas pressure, remove the burner cap and connect a manometer
(water gauge) or other pressure test device to the burner orifi ce. Use a rubber hose
with inside diameter of approximately ¼” hold the end of the tube tight over the
orifi ce. 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 specifi ed 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
fl ame, you must use the NG pilot orifi ce
included in the conversion kit and this will
ensure the pilot fl ame is the correct size
(see image).
NOTE:
Once the unit has been converted
fi ll 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 fl ame and oven burner fl ame
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.
