American Dryer Corp MLG32PD3 installation manual Inches Water Column 26.1 mb

NOTE: The dryer can be stopped at any time by opening the main door. To restart dryer, shut the main door and press desired fabric setting.

4)Open main door to stop the dryer, and change to a different fabric setting. Repeat this procedure, until ALL fabric selections have been tested. This will also confirm that setting key circuits and door switch circuits are functioning properly.

5)Repeat above procedure for the other basket (tumbler).

2.Heat Circuit Operational Test

a.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.

NOTE: Gas dryers are equipped with a Direct Spark Ignition (DSI) system, which has internal diagnostics. If ignition is not established after the first attempt, the heat circuit in the DSI module will lockout until it is manually reset. To reset the DSI system, open and close the main door and restart the dryer.

b.Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column pressure is correct and consistent.

NOTE: Water column (W.C.) pressure requirements (measured at the pressure tap of the gas valve body):

Natural Gas -----------------------	3.5 Inches Water Column (8.7 mb).
Liquid Propane (L.P.) Gas ------	10.5 Inches Water Column (26.1 mb).

IMPORTANT: THERE IS NO REGULATOR PROVIDED IN A L.P. DRYER. The water column pressure must be regulated at the source (L.P. tank) or an external regulator must be added to each dryer.
