### 9.2.7. Table of assembly parameters of radiant heating

Table of assembly parameters is designed for the fitter. The assembly parameters table is designed for the fitter of the heating system (contractor). Printout of assembly parameters, together with printed drawing and bill of materials forms complete documentation for project execution.

Manifold label is at the top of the table:

Manifold: | symbol (name) of manifold |
No. of outlets: | number of outlet ports in manifold, including spare ports, specified in data table |
Type: | type of manifold from catalogue |
s.v.: | type of supply valve |
r.v.: | type of return valve |
Manifold cabinet: | type of manifold cabinet from catalogue |

All lines below with results for rooms and HZ’s within them apply to this manifold down to the label of the next manifold or label of a HZ heated by pipe feeds. The line with room results includes the following fields:

Description of assembly parameters always consists of two lines, as the field concerning the fastening system is always displayed. The label will be displayed in bold font if the pipe fastening system used in the room is other than the default system. Assembly parameters of room include the following fields:

Room: | symbol (name) of room |

No. of HZs:

number of heating circuits within the room

– incl.: ... to other manifolds; (optional!)

Number of heating circuits connected to other manifolds. When heating circuits of one room are connected to several manifolds, the results for this room will be displayed for each of those manifolds, and HZ’s will be listed for the currently described manifold. This field will also provide information on the number of HZ’s connected to other manifolds.

– ... HZ's heated by pipe feeds; (optional!)

If a room has HZ’s that are heated by pipe feeds only, then this field will provide this information. The number of circuits (previous field) in a room with only one HZ, that HZ being heated by pipe feeds, is equal to zero!

Pattern same as default / Pattern other than default / Pipe laying pattern

name of pattern selected from catalogue

As opposed to RH results, the name of the fastening system is always present in the assembly parameters, and makes up the second line of room label. This line can take on one of the following three forms:

– first option (‘Pattern same as default: <Pattern_Name>’) is applied to the rooms where the default pattern defined in general properties of the project is used

– second option (‘Pattern other than default: <Pattern_Name>’) is applied to the rooms where other pipe fastening system than default is used. The label (both lines) is displayed in bold font

– third option (‘Pipe laying pattern: <Pattern_Name>’) is applied to all rooms when no default pattern has been defined

Assembly parameters bar for a single HZ contains the most information required to install the heating circuit properly. It consists of the following fields:

! Assembly parameters for HZ with calculation errors (e.g. exceeded max. pressure drop) will not be displayed! To obtain complete assembly parameters, all errors must be eliminated at the stage of calculations.

HZ Symbol Floor covering / Rlb | top line: symbol (name) and type of heating surface bottom line: type of floor covering and its heat resistance. If a numerical value was entered as the covering, rather than being selected from the list of available options, <cov. unknown> appears along with the specified value of heat resistance of the covering | [(m2K)/W]

PZ / OZ

This field describes the contents of the following two fields with which it creates a set of results separated from other fields by continuous vertical lines

– if the HZ has no integrated peripheral zone, “OZ” appears in the top line in case of circuit that forms occupied zone or “PZ” in case of circuit defined as peripheral zone forming a separate circuit. Bottom line remains empty.

– in the case of HZ with PZ integrated with OZ, the top line displays “cPZ” for a PZ created by compacting the pipe laying pattern or “uPZ” for a PZ connected upstream of OZ. In the following three result fields, the first line refers then to this integrated PZ. The bottom line displays “OZ” and the second line of the following two result fields will then refer to the part of circuit that forms occupied zone.

area | effective area of HZ or of separate parts of HZ (see explanation of “PZ / OZ" field). Covers the total effective area of HZ, including the area of pipe feeds running across the HZ. In case of HZ’s with integrated PZ, the area of pipe feeds is always subtracted from the part of HZ forming OZ, even if the pipe feeds on the drawing run across the peripheral zone | [m2]
T (or B, b, p, r, VA) | pipe spacing within HZ or in its separate parts (see explanation of “PZ / OZ” field) | [mm] [cm] [m]
Pipe type Pipe laying pattern | top line: type of pipe used in the heating zone bottom line: pipe laying pattern in the circuit, specified in HZ properties |
No. of circ. | number of heating circuits in the room |
Total len. pipes feed+circ. | top line: total length of pipes of the heating circuit, including the length of pipe feeds bottom line: length of pipe feeds running from manifold to the circuit + length of pipe forming the proper heating circuit. The sum of these two values is equal to the total length in the top line |
Valve set. | setting of valve on the manifold controlling flow in the circuit. Designation in the second line indicates to which valve the setting applies to: on the return end – “(R)”, on the supply end – “(S)” |
Floor layers | This field displays insulation layers under the heating panel, form structural slab downwards |

As in the calculation results table, assembly parameters for HZ heated by pipe feeds are displayed separately and are grouped within a section following the last manifold of that section.

The relative arrangement of description of the group of HZ’s heated by pipe feeds, room labels and result bars for individual HZ’s is identical to that of standard HZ’s. The only difference is in the range of fields and their meaning.

The header of assembly parameters for this type of HZ includes the following fields:

Zones heated by pipe feeds assigned to source: <Source_Name>;

Name of the source supplying the HZ’s listed below heated by pipe feeds.

This bar has the same fields as that of a standard HZ. However, not all of them are filled in. Important fields include:

HZ Symbol Floor covering / Rlb | same as for standard HZ | [(m2K)/W]
area | same as for standard HZ | [m2]
T (or B, b, p, r, VA) | pipe laying spacing valid for those pipe feeds running across the HZ heated by pipe feeds, for which the (auto) option was selected in properties. Some pipe feeds may be laid with other spacing specified by the user in properties. Detailed information is given in the table of assembly parameters for individual pipe feeds displayed when printing | [mm] [cm] [m]
Pipe type Pipe laying pattern | the “heated by pipe feeds” option is always assigned to HZ’s heated by pipe feeds |
Floor layers | same as for standard HZ |
