Gas Pressure Test Procedure
!
WARNING
Electric Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electric
shock.
1. Disconnect power to the dryer.
2. Turn off gas supply using the shutoff valve that supplies
the dryer.
3. Remove the back panel from the dryer.
4. Locate the output pressure tap screw on the gas valve
and unscrew 4 to 5 full turns.
5. Connect the airtight hose to pressure tap post. (Airtight
hose will attach between pressure tap post and
manometer.)
6. Feed hose through an opening in the back panel while
reattaching the back panel to the dryer.
7. Connect opposite end of hose to manometer.
8. Turn on gas supply using the shutoff valve that supplies
the dryer and reconnect the power.
9. Start the dryer in Heat Mode and wait for ignition.
10. Record the manometer reading.
11. Once test is complete, disconnect power to the dryer.
12. Turn off gas supply using the shutoff valve that supplies
the dryer.
13. Remove the back panel from the dryer.
14. Disconnect manometer.
15. Remove hose from pressure tap post. Tighten screw
inside the pressure tap or install plug.
Leak Check
1. Turn on gas supply.
2. Reconnect power to the dryer.
3. Turn on dryer.
4. Brush or spray an approved noncorrosive leak-detection
solution onto pressure tap and union nut and inspect for
leaks indicated by growing bubbles.
5. If an bubbles are present, turn off gas supply, tighten the
leaking connection and retest for leaks.
6. If dryer was moved during conversion, use the same
method for leaks in the flexible gas supply line and fittings
between the dryer and the gas supply pipe.
7. If any bubbles are present, tighten the leaking connection
and retest for leaks.
8. Reinstall the back panel.
9. Repeat for other pocket.
Preparation for Operation / Start-Up __
The following items should be checked before attempting to
operate the dryer:
• Read all “DANGER”, “WARNING”, “CAUTION”, and
“DIRECTION” labels attached to the dryer.
• Check incoming supply voltage to be sure that it is the
same as indicated on the data label.
• Be sure that all gas shutoff valves are in the open
position.
• Be sure all back panels (guards) and electric box covers
are in place.
• Be sure the service doors are closed and securely in
place.
• Be sure the lint door/drawer is securely in place.
• Rotate the tumbler (drum) by hand to be sure it moves
freely.
• Check bolts, nuts, screws, terminals, and fittings for
tightness and security.
• Check that the vent is connected to the dryer and is
exhausted to the outdoors.
Preoperational Test ___________________
All dryers are thoroughly tested and inspected before leaving
the factory. However, a preoperational test should be
performed before the dryer is publicly used. It is possible
that adjustments have changed in transit or due to marginal
location (installation) conditions.
Turn on electric power to the dryer.
Refer to the operating instructions for starting your dryer.
Open all shutoff valves.
When a gas dryer is first started (during initial start-up), it
has a tendency not to ignite on the first ignition attempt. This
is because the gas supply piping is filled with air, so it may
take a few minutes for the air to be purged from the lines.
NOTE: During the purging period, check to be sure that all
gas shutoff valves are open.
Tumbler Coating
The tumbler is treated with a protective coating. We suggest
dampening old garments or cloth material with a solution of
water and nonflammable mild detergent and tumbling them
in the tumbler to remove this coating.
Each tumbler should be operated through one complete cycle
to ensure that no further adjustments are necessary and
that all components are functioning properly.
Microprocessor Programs / Selections
Each microprocessor controller (computer) has been
preprogrammed by the factory with the most commonly used
parameter (program) selections. If computer program
changes are required, refer to the computer programming
manual, which was shipped with the dryer.
