TYPICAL NATURAL GAS INSTALLATION

TYPICAL L.P. GAS INSTALLATION

Gas Connections

Inlet  connection ..... 1/2”  M.N.P.T.
Inlet supply size ..... 1/2”  Pipe  (minimum)

Piping/Connections

The dryer is provided with a 1/2” N.P.T. inlet pipe connection
out  the  rear  of  the  dryer.    It  is  recommended  that  a  gas
shutoff valve be provided to the gas supply line of each dryer
for ease in servicing.

There  should  be  a  minimum  6-inch  (15.24  cm)  clearance
between the back guard and the first bend in the gas piping
for ease of servicing.

The  size  of  the  main  gas  supply  line  (header)  will  vary
depending on the distance this line travels from the gas meter
or, in the case of L.P. gas, the supply tank, other gas-operated
appliances  on  the  same  line,  etc.    Specific  information
regarding supply line size should be determined by the gas
supplier.

NOTE: 

Undersized gas supply piping can create a low or

inconsistent pressure, which will result in erratic operation
of the burner ignition system.

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.

!

 WARNING

Consistent gas pressure is essential at all gas connections.
It is recommended that a 3/4-inch (19.05 mm) pipe gas loop
be installed in the supply line servicing a bank of dryers.  An
in-line pressure regulator must be installed in the gas supply
line  (header)  if  the  (natural)  gas  pressure  exceeds  13.0  in
wc (32.34 mb) pressure.

A plugged tap, accessible for a pressure gauge connection,
must  be  installed  in  the  main  gas  supply  line  immediately
upstream of the dryers.

IMPORTANT:

 Pipe joint compounds that resist the action

of natural, propane, and butane gases must be used.

Test all connections for leaks by brushing on a soapy
water solution (liquid detergent works well).

Gas Pressure Test Procedure

1. Disconnect power to the dryer.

2. Turn off gas supply using the shutoff valve that supplies

the dryer.

3. Remove the toe panel from the dryer.

4. Turn gas cock in gas supply line to “OFF” position.

5. Install pressure tap and attach manometer.

6. Turn gas cock to “ON” position.

7. Turn on gas supply using the shutoff valve that supplies

the dryer and reconnect the power.

8. Start the dryer in Heat Mode and wait for ignition.

9. Record the manometer reading.

10. Once  test  is  complete,  disconnect  power  to  the  dryer,

turn  gas  cock  to  “OFF”  position.    Remove  manometer.
Tighten screw inside the pressure tap or install plug.
