SECTION 6: SUGGESTED LAYOUTS SECTION 6: SUGGESTED LAYOUTS The following are suggested layouts for the heater. These layouts are effective in maximizing the heat pattern and overall performance of the heater. All heaters can be common vented or individually vented (See Page 34, Section 9) depending on the building requirements. These are only suggested layouts. The heater can be designed in various configurations provided they are in the guidelines of this manual. When designing a U-Tube or Elbow

Coupling Assembly with Lock Reflector End Cap Punch out center section to accommodate tube. Tube and Reflector Hanger Suspend system from these hangers. Flex Gas Line with Shut Off Cock Tube Hot Rolled or Heat Treated Aluminized Tube Supplied in 10' (3 m) lengths. Burner Tube Supplied in 10' (3 m) lengths. Burner tube is always the first tube after the burner. Reflector Support Strap & Wire Form Turbulator Turbulator must be installed in the last standard section of tube. Turbulator is not requi

All dimensions are from the surfaces of all tubes, couplings and elbows. 2. Clearances B, C and D can be reduced by 50% after 25' (7.5 m) of tubing downstream from where the burner and burner tube connect.

The T and Fork layouts have a tee or cross (called the "last tee" or "last cross") where the combustion gases in the system enter the tee or cross with directly opposing flow directions, which creates an added source of pressure drop in the system. This additional source of pressure drop requires some difference in how the allowed manifold length is calculated. In this case, we have to differentiate manifold tube that is located between the radiant pipe and the last tee (or cross) from manifold

Reflectors can be used over the manifold tube but are not required. The system design parameters are such that the manifold sections are not subjected to condensate when the system is fully heated up. It is required that heat-treated aluminized or coated tubing is used for the manifold to increase system life and to handle initial condensation during start-up. Damper couplings may be necessary to balance system vacuum. Design requirements for a CTHN multiburner system are summarized on Page 30,
