Burner Pressure Measure And Adjust; Steam Information - ADC AD-115ES Installation & Operator's Manual

Conversion Instructions
(Refer to figure)
1. Discontinue electrical power to the dryer.
2. Close shutoff valve in the dryer's gas supply line.
3. Disconnect gas valve wiring (label wires first).
4. Disconnect the union (A) between the external shutoff and
the gas valve (B).
5. Remove screws (C) and remove the gas valve (B) with
manifold (D) assembly from the dryer.
6. Replace the main burner injector (E) with the correct injector
(see Gas Specification Chart).
7. Instructions on how to convert the gas valve is included
with the gas valve conversion kit (see chart).
8. Reverse step 4 to install the gas valve (B) with manifold
(D) assembly.
9. Open shutoff valve in the dryer's gas supply line.
10. Test all connections for leaks.
11. Connect gas valve wires.
12. Continue electric power.
13. Provide proper gas pressure to the injector (see chart):
Gas supply pressure for categories I
regulated in the dryer's gas supply line.
All other gas categories require adjustment of the gas
valve's internal regulator; instructions below.
14. Replace the original rating plate with the rating plate.

Burner Pressure Measure and Adjust

(Refer to figure)
1. Discontinue electrical power to the dryer.
2. Turn the gas valve's switch (H) to "OFF" position.
3. Back out the miniature screw inside the outlet pressure
tap ("out P") (G).
4. Attach a manometer to pressure tap (G).
5. Turn the gas valve's switch (H) to the "ON" position.
6. Continue electrical power to the dryer.
7. Run a "heat" cycle and wait for burner ignition.
8. Gas manifold pressure can now be measured.
113579 -1
9. If the gas pressure does not need adjustment then
10. Turn the gas valve's switch (H) to "OFF" position.
11. Remove manometer and tighten pressure tap screw (G).
12. Turn the gas valve's switch (H) to "ON" position.
13. Continue electrical power to the dryer.
Care must be taken when leveling a steam dryer to promote
good steam coil drainage. Return lines should be level or
pitched down slightly for good drainage.
The steam supply to the coil must be from the top of a well-
dripped steam main. If the supply run-out to the dryer exceeds
6 meters then it should be dripped just before the control valve
with a proper trap and dirt pocket.
The normal pH level for copper-type steam coils must be
maintained between 8.5 and 9.5. For steel-type steam coils
the pH level must be between 9.5 to 10.5. These limits are
required to limit the acid attack of the steam coils.
Properly sized steam supply, and return, lines are required to
avoid poor performance.
Clean, dry steam must be provided to the dryer.
and I must be
2E+ 3+
The steam supply connection into the main supply line must
be made with a minimum 25 cm riser. This will prevent any
condensate from draining towards the dryer.
The steam supply line to the dryer must include a 30 cm riser
along with a drip trap and check valve. This will prevent any
condensate from entering the steam coil.
Flexible hoses or couplings must be used. The dryer vibrates
slightly when operating which could cause steam connections
to crack if they are hard piped.
Horizontal sections of steam supply piping should be pitched
back towards the steam supply header (minimum slope of 1
cm for every meter) to allow any condensation to flow back
into the header. Install a bypass trap in any low point to eliminate
wet steam.
Failure to comply with the above requirements can result in
water hammer, premature component failure, and will void the
warranty.
Inverted steam bucket trap must have a capacity of 332 kg/hr
at 8.62 bar for AD-115ES and AD-120ES, and 473 kg/hr at
8.62 bar for A D-170.

disconnect electric power and go to step 10, otherwise:
9.1. Disconnect electrical power to the dryer.
9.2. Regulator screw is under the regulator cap (F).
9.3. Remove the regulator cap (F) and turn the plastic
adjustment screw to alter the pressure (clockwise to
increase, or counterclockwise to decrease).
9.4. Continue electrical power to the dryer.
9.5. Run a "heat" cycle and wait for burner ignition.
9.6. Gas manifold pressure can now be measured.
9.7. If the manifold pressure needs further adjustment then
return to "Step 9.1."
9.8. Disconnect electrical power to the dryer.
9.9. Replace the regulator cap (F).
