Steam Connection (Only For Steam-Heated Variants); Hot Water Connection (Only For Hot Water-Heated Variants); Gas Connection (Only For Gas-Heated Variants) - Miele PDR 514 Operating And Installation Instructions

Configuring the room ventilation opening
 Rooms in which rotary irons and tumble dryers are operated must have an induced
ventilation system (e.g., ventilation slots in windows and doors, wall openings with
grilles, or opened windows or skylights).
For example 1
A duct diameter of 6" (150 mm) was specified in example 1. According to this duct diame-
ter, a room ventilation opening with a size of 17' 5" (531 cm) is required. The edge length is
9 1/16" (230 mm) (see Table 3).
For example 2
A total duct diameter of 8 11/16" (220 mm) was specified. According to this duct diameter,
a room ventilation opening with a size of 37' 4" (1,140 cm) is required. The edge length is
14 13/16" (377 mm) (see Table 3).
For example 3
Since in this case the tumble dryer is connected to a central air supply, additional ventila-
tion openings are not needed.

Steam connection (only for steam-heated variants)

The steam connection must only be carried out by an authorized installation technician.
The enclosed installation instructions must be observed as they are important for the
steam connection.

Hot water connection (only for hot water-heated variants)

The hot water connection may only be carried out by an authorized installation technician.
The enclosed installation instructions must be observed as they are important for the hot
water connection.
If a faucet is desired, it must be installed on site.

Gas connection (only for gas-heated variants)

The gas connection must only be carried out by an authorized installation technician in ac-
cordance with the applicable national regulations (see installation instructions).
The installation must conform with local codes or, in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installa-
tion Code, CSA B149.1
The dryer and its manually operated appliance main gas valve must be disconnected from
the gas supply piping system during any pressure testing of that system at test pressures
in excess of 1/2 psi (3.5 kPa).
The dryer must be isolated from the gas supply piping system by closing the equipment
shutoff valve during any pressure testing of the gas supply piping system at test pressures
equal to or less than 1/2 psi (3.5 kPa).
A minimum 1/8-in NPT plugged tapping, accessible for test gauge connection, must be in-
stalled immediately upstream of the gas supply connection to the dryer.
