Pressure Switch
When using natural gas (NG), there is a pres-
sure switch that acts to turn off the gas ow to
the pilot if the inlet pressure exceeds 9" WC.
This is to prevent the operation of the unit on
the wrong gas (propane/LP). If your natural gas
supply exceeds 9" WC the unit will not operate.
Either contact your gas supplier to check and
adjust the inlet pressure or a qualied service
technician can bypass the pressure switch.
Before attempting to bypass the pressure
switch, make sure the type of gas being used
is correct. Check to make sure the connection
tting is in the correct inlet on the regulator.
Refer to Connecting to Gas Supply, page 15.
Only a qualied installer should bypass the
pressure switch. To bypass the pressure
switch locate the set screw on the regulator.
Use a small at bladed screw driver to turn the
set screw counterclockwise 2 turns. This will
bypass the pressure switch function.
Problem Possible Cause Corrective Action
Using natural gas and
pilot will not light.
Inlet pressure exceeds 9" WC. Bypass pressure switch. See
instructions below.
The entire gas delivery piping including con-
nections inside the heater should be leak
tested by the qualied installer. After leak
testing the qualied installer should light the
appliance. Refer to the correct ame pattern
as illustrated on page 23. All ame patterns
should be safely inside the product. If for any
reason they are not, stop use of the appliance
and call for repairs.
