CHECKING THE PRESSURE
REGULATOR
The pressure regulator must be checked at a
minimum 1
"
water column above the set pressure.
The inlet pressure to the regulator should be set as
follows:
a) Set the minimum pressure using natural
gas @ 5
"
and for L.P. gas @ 11
".
b) Set the maximum pressure at 14
"
.
For testing the line pressure above
1
/2
psi with a
pressure gauge:
a) Disconnect the appliance and its individual
shutoff valve from the gas supply when the
pressures are greater than
1
/2
psi (3.5 kPa).
For testing the line pressure @
1
/2
psi or lower with
a pressure gauge:
a) Close the gas supply shutoff valve to the
appliance when the pressures are equal to,
or less than
1
/2
psi (3.5 kPa).
NOTE: If you are converting the range for L.P. gas,
proceed to the next page. If not, proceed to “Check-
ing The Maintop Burner Operation” on page 1-13.
Fire Hazard
Turn off the main gas supply before you try to
stop a leak.
Be sure that all leaks are stopped before lighting
pilots or burners.
Do not use an open flame to test for gas leaks.
Failure to follow these instructions could result in
a possible fire, or explosion.
WARNING
CHECKING FOR LEAKS
1. Make sure that no open flame is present, then
open the gas line shutoff valve and the regu-
lator shutoff valve.

2. Turn one of the burner gas valves on until the
air in the line is expelled and gas begins to
flow out the burner, then turn the valve off.
3. Use a brush and liquid detergent and check all
the connections for possible leaks. If bubbling
occurs around the joint, tighten the connec-
tion further until the bubbling just stops. Do
not overtighten the connection.
