Gas Pressure Testing

Attach the manometer to the test port as
shown in the photo.
Natural gas should be set at approximately
5 inches of water column.
Propane should be set at approximately
10 inches of water column.
Remember that the valve is already
adjusted and pre-set at the factory for
both types of gas. If your pressures are
reasonably different from what you
expected, perhaps you should check the
pressure on the incoming gas line.
To test the gas pressure, burner operation
(gas dryer,) or heater (electric dryer,) the
servicer must fabricate a bulkhead cover to
allow the blower to pull through the system
as if the dryer were fully assembled and in
normal operation. To accomplish this,
remove the front cover, tape the door
switch into the closed position, and cover
the door opening with a piece of
cardboard.
Insert a 2-foot test pipe with fittings for a
temperature probe and a manometer. (See
page 57.)
Under these conditions, you can measure
input gas pressure, vent temperature, and
static vent pressure under normal
operating conditions.
