Preparation For Operation / Start-Up - Maytag Commercial MLG45 Installation Manual

Gas Pressure Adjustment
1. Disconnect power to the dryer.
2. Turn off gas supply using the shutoff valve that supplies the
dryer.
3. Disconnect the manometer and remove the back panel from
the dryer.
4. Locate and remove the regulator cap with a screwdriver to
gain access gas valve's internal regulator adjusting screw.
5. Use a small flat blade screwdriver to turn the plastic
adjustment screw in the valve. Turn the screw clockwise to
raise pressure and counterclockwise to lower pressure.
NOTE: Outlet pressure is measured with the burner in
operation for all burner adjustment conditions. Therefore,
once the necessary adjustments have been made, the
dryer must be operated in a heating cycle to verify that the
pressure is correct.
6. Feed manometer 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. Run the dryer and check the outlet pressure. If the pressure
is not correct, discontinue the power to the dryer and repeat
steps 1 thru 8. Do this as many times as necessary to
achieve the correct burner pressure.
10. Once the adjustment of the valve is complete, the regulator
cap must be replaced and sealed with, for example, paint to
prevent tampering by the user.

Leak Check
1. Be sure the gas supply is turned on.
2. Turn on dryer.
3. Brush or spray an approved noncorrosive leak-detection
solution onto all connections and inspect for leaks indicated
by growing bubbles.
4. If dryer was moved during testing, use the same method
to check for leaks in the flexible gas supply line and fittings
between the dryer and the gas supply pipe.
5. If any bubbles are present, turn off gas supply, tighten the
leaking connection and retest for leaks.
