Model and Dimension Table

Dimensional Diagram Overview

A diagram illustrates the convector's mounting options (wall/floor) and key dimensions. It shows the front panel with louvers, the cabinet structure, and indicates dimensions like 'D' for depth, 'L' for length, 'H' for height, and 'B'/'J' for connection points. A note specifies that adding end pockets increases liner and front length.

STEAM RATINGS IN BTU/H (215°F at 65°F EAT)

The following tables provide detailed steam ratings in BTU/H for Type FS-A and Type FSG-A convectors, based on specific depths, lengths, and configurations.

Correction Factors and Performance Data

The following tables provide correction factors for BTU performance and other operational data.

Table 3: Convector Correction Factors

Based on Section 35.4 ASHRAE HVAC Systems and Equipment

Table 4: Correction Factors for Steam Pressures Other Than 1 PSI GAUGE

*Apply factors shown above to the ratings shown on the 215°F ratings page.

Note: Max Recommended operating pressure 150 PSIG, (365.9°F). For conversion from steam to hot water, use correction factors shown in Table 3.

Table 5: Correction Factors for Access Doors

Note: Derating factors do not apply to units with end pockets.

Table 6: Pressure Loss in Feet of Water

Charted figures showing pressure drop through Convectors with forced hot water. Used for determining pressure head requirement. Based on 64" length units, but applicable to shorter units, as most loss is due to headers.

Table 7: Gallons Per Minute of Hot Water Required

This is a graphical representation (chart) showing Gallons Per Minute (GPM) of hot water required versus MBH (Thousand BTU per Hour) for different temperature drops (10°F, 20°F, 30°F, 40°F). The chart indicates the relationship between flow rate and heat output for various temperature differentials.

Table 8: Output-Flow Rate Corrections

Note: Table 8 shows MBH which result at specific water temperature drops and minimum water flow rates which are required to maintain turbulent flow within element tubes.

Convector Coil Assembly Diagram

This diagram details the convector coil construction. It shows coil options based on depth: 4" (2 Tube Element, 3 3/4" width), 6" (3 Tube Element, 5 3/4" width), and 8" (4 Tube Element, 7 3/4" width). The diagram indicates the 'End to End Length' is the liner length plus 1/2 inch, and 'Riser Centers' are the liner length minus 2 1/2 inches. It also shows a 3/4" NPT typical connection, a vent plug, and a 3-position hanger welded to the liner. A note clarifies that overall physical length increases by 4" for each end pocket, while coil length remains standard. Coil fins are 2-1/2" high, bonded to copper tube at 6 fins per inch.
