Explosion hazard!
Use a new AGA or CSA approved gas supply line.
Install a shut off valve.
Securely tighten all gas connections.
Have a qualified person make sure gas pressure does not exceed 14 in. W.C./ 3.49 kPa/ 0.506 psig. (Natural and Propane Gas).
Example of a qualified person include:
Failure to do can result in explosion or fire.
Risk of death or injury!
All gas line connections must be tested for leaks prior to appliance operation. Apply soapy water to gas line connections and check for formation of new bubbles. Bubbles indicate leak!
When installing the gas supply to the gas dryer inlet pipe, do not exceed 310 lbf in (35 Nm).
Never use an open flame to test for gas leaks.
This gas dryer when equipped for use with NATURAL GAS, will employ an orifice size 46 and have a gas outlet pressure of 3.5 in. W.C. This gas dryer when equipped for use with PROPANE GAS, will employ an orifice size of 1.21 mm, and have a gas outlet pressure of 11 in. W.C.
Your dryer must have the correct valve for the type of gas in your home. Valve information is located on the rating plate behind the door below the drum. If the rating plate information does not agree with the type of gas available, contact your dealer or our customer service team.
1/2" I.D. pipe is recommended.
3/8" approved tubing is acceptable for lengths under 20 ft (6.1 m) if local codes and gas supplier permit.
Must include 1/8" NPT plugged tapping, immediately upstream of the gas connection.
A shut off valve must be included:
The shut off valve should be easy to reach for opening and closing.
Note:
The dryer must be checked for proper operation whenever the gas connections have been broken.
Dryer gas pipe
The gas pipe that comes out through the rear of the dryer has a 3/8" male pipe thread.
Connection must be made by a qualified technician.
The dryer must be disconnected from the gas supply piping system during testing pressure.
When using for the first time make sure that there is no air in the piping system.
Do not use copper pipes and tubing if connected to natural gas.
The connection may be different, according to the supply line type, size and location.
If local codes permit, use a flexible stainless steel connector (Design certified by the America Gas Association or CSA International) to connect the dryer.
To reduce the distance between body sheet and wall install a 3/8" elbow on the gas pipe of the dryer.
The Bosch dryer must be vented outdoors. To prevent build up of moisture and accumulation of lint indoors, as well as to maintain maximum drying efficiency, it is recommended that the dryer is vented outdoors.
The dryer is delivered with an exhaust air outlet on the rear of the appliance.
To take account of the spatial requirements and an existing exhaust air system, the following connection options are possible for the exhaust air outlet:
Special exhaust air connections must be obtained from our customer service for either connection type
A qualified technician should change the exhaust air outlet to the optional connection location.
To ensure optimum performance, the ducting system of the dryer should be as short as possible with a minimum number of elbows. Your dryer will work best when the venting system has as few air flow restrictions as possible. Exhaust ducting which is longer than recommended may extend drying time, cause lint to accumulate and affect dryer performance and dryer life.
Four-inch (approx. 100 mm) diameter ducting should be used. Use either rigid metal or flexible metal ducting material. DO NOT use plastic or non metal duct with this dryer.
DO NOT assemble the ductwork with screws or fasteners that extend into the duct. They will serve as an accumulation point for lint.
Joints should be secured with aluminium tape.
All joints should be tight to avoid leaks. The male end of each duct section must point away from the dryer.
Whether connecting to an existing venting system or a new venting system, make sure that all ducting is clean and free of lint.
The maximum permitted length for both rigid and flexible metal duct is shown in the table below.
Number of 90° Turns or Elbows | Rigid Duct | Flexible Duct |
0 | 66 ft. (2011 cm) | 45 ft. (1372 cm) |
1 | 56 ft. (1707 cm) | 36 ft. (1097 cm) |
2 | 48 ft. (1463 cm) | 29 ft. (884 cm) |
3 | 39 ft. (1189 cm) | 22 ft. (671 cm) |
4 | 30 ft. (914 cm) | 16 ft. (488 cm) |
Note:
Side and bottom exhaust installations have a 90° turn inside the dryer. To determine maximum exhaust length, add one 90° turn to the chart.
More than two 90° turns are not recommended. For best performance, separate all turns by at least 4 ft. of straight duct, including distance between last turn and exhaust hood.
The exhaust duct must end with an approved exhaust vent hood with swing out damper(s). DO NOT use an exhaust vent hood with magnetic latches.
To avoid exhaust restriction, the outlet must be a minimum of 12 inches (30 cm) above ground level or any other obstructing surface.

Tips on saving energy
To save energy, money and time, Bosch recommends the following:
Before you use the dryer for the first time:
Operate your dryer only when you are at home. If you intend going on vacation or are not using your dryer for an extended period of time, you should:
Identification of fabrics
Observe the treatment symbols on the textile labels. They provide valuable information as well as limitations about the drying process.
Do not dry the following textiles in the dryer:
Dry woolen or wool rich textiles with dryer rack only!
Use the time program "Air fluff/No heat" to dry articles containing foam rubber or similarly textured rubber like materials.
Drying tips
In principle, the following applies to all drying programs:
For optimum drying results your dryer offers several program groups and additional options.
Select the required drying program from the program table according to the examples.
There are automatic programs for different types of textiles.
(Regular/Cotton or Permanent press).
Regular/Cotton
Permanent Press
The program sequence of automatic programs is controlled via sensors. The duration of the program depends on the measured degree of moisture in the laundry and on the selected degree of dryness (e.g. Damp dry or Extra dry).
Time programs run for a specific time (20, 40, 60 minutes).
In the "Air fluff/No heat" stage the dryer runs on ambient air without a heat supply for 20 minutes.
Dry woolen or wool-rich textiles with dryer rack only!
Delicates low temp.
Press the "Delicates low temp." button for temperature sensitive textiles. Observe the care information or symbols on the textiles. The temperature of the drying process is reduced, the drying time is extended.
Signal
Your dryer outputs different signals, if the "Signal" button is pressed.
Signal | Type |
Start | Short tone |
End | Sequence of short tones |
Mal operation | Sequence of long tones |
Warning of malfunction | Sequence of long tones |
The signal "Warning of malfunction" is active in any case.
The dryer uses an electronic scanning system for all programs except the time programs. A moisture sensor continuously checks the moisture in the laundry. Drying ends automatically as soon as the selected degree of dryness has been reached. The drum continues to rotate at specific intervals for one hour to prevent creasing.
The current degree of drying and the level reached during the program sequence is indicated via indicator lights (Drying, Damp dry, Regular dry, Wrinkle block).
If the indicator light "Wrinkle block" illuminates when the program selector is in Off - Position - turn off the circuit breaker and call for customer service!

TO AVOID RISK OF EXPLOSION!
Never use solvents or highly flammable liquids for cleaning.
Incorrect cleaning may damage the dryer. Do not spray with a water jet. Do not use scouring agents or all purpose cleaners. Do not use steam cleaners.
Wipe the housing and fascia with a soft cloth and soapy water only.
Wipe the drum, door seal and inside of the door with a damp cloth only.
A dirty filter extends the drying time and increases energy consumption.
The filter should be cleaned before and after each drying process.
If a warning signal and an E01 warning message are emitted during a drying program, clean the filter immediately and check the exhaust duct.
The program interrupts automatically.
Inspect and clean the exhaust ducting at least once a year to prevent clogging. A partially clogged exhaust can lengthen the drying time.
Remove gas connection before moving the dryer to clean the duct. Be careful not to destroy the gas connection when cleaning the duct.
The moisture sensor has to be cleaned because a fine layer of transparent buildup is deposited on the sensors.
This deposit can easily be removed by wiping the sensors (the two bars next to the lint filter) with a cloth and a little white vinegar.
Use white vinegar only!
Clean the moisture sensor once a month.
Over time, fluff from the drying process collects in the bearing shield.
This fluff can be easily removed using your vacuum cleaner, at least once a month.
The dryer light turns on inside the drum when you open the door.
