SECTION 7: EXAMPLE CRV-SERIES SYSTEM LAYOUTS

Systems that are symmetrical are preferred because the vacuum available in the system branches are bal- anced as a function of design (damper couplings are not needed).

FIGURE 18: Example System Layout (Option 1)

Where radiant tube lengths are variable in a single branch, the average length shall be used to determine the total radiant tube length. Tailpipe will begin after the last radiant tube following the last burner in the branch.

CRV-Series is most effective when there are at least 3 burners in the radiant branch.

To assist with the selection of burners and system designs, the following figures show system layouts that have been used extensively with CRV-Series since 1962. Designing systems using these layouts will mean altering the dimensions to suit the individual building.

Generally, shared tailpipe reduces the available sys- tem vacuum. See Page 14, Section 5.3 for shared tailpipe design rules.

7.1 Example System Layout (Option 1)

Six B10 burners at minimum radiant tube length and

2.5ft/flow unit tailpipe, the recommended pump for this system is an EP-200 Series pump.

This system provides maximum radiant intensity on the left and right and adds supplemental radiant effects through the center creating very even radiant effects over the coverage area.

Layout to provide high system efficiency, condensed radiant output and good uniformity of distribution. Adjust the lengths as necessary for different input sys- tems and to change the efficiency levels.
