GAS RANGE Page 29 of 72 TRAINING MANUAL
REGULATING GAS PRESSURE
Correct gas pressure is essential for quick burner ignition, correct burner BTUH
input, and to minimize the byproducts of combustions, such as carbon monoxide.
The recommended regulated pressure for natural gas is 3.5 to 4 inches of water
column. Likewise, for LP the recommended pressure is 10.5 to 11 inches of
water column.
To measure the gas pressure, you’ll
need either a digital or water (slack
tube) manometer.
Measuring gas pressure can be easily
accomplished at any of the 5 surface
burners.
Remove a burner grate and one of the
sealed burners. Then place the gas
pressure measuring tube over the
orifice.
With the pressure fitting over the orifice
and the range unplugged, turn the
surface valve to an open position and
record the gas pressure.
If the gas pressure measured is incorrect, check the gas regulator cap position. If
it is properly installed for the gas type (natural or LP), replace the regulator and
retest pressure.
(See the LP Conversion section for gas regulator cap positioning on page 43.)
