<strong>AIR</strong> <strong>DUCT</strong> <strong>HEATERS</strong> TYPES EDFF, EDIF<br />
<strong>AIR</strong> <strong>DUCT</strong> <strong>HEATERS</strong> (continued)<br />
Types EDFF and EDIF duct heaters are designed and<br />
approved for comfort heating applications. Unit must be<br />
installed in a horizontal duct with the terminal housing at the<br />
side or bottom.<br />
Tandem mounting (more than one heater in series) is<br />
permitted within certain limitations. See previous discussion.<br />
Units listed in Table 2 are representative only. It is<br />
reasonably safe to specify any similar unit using this table<br />
as a guideline, and we will build to your specifications.<br />
