SMART HEAT
* Field convertible to 1 phase.
† KFAEH2501N09 is field convertible to 3 phase.
‡ Single point wiring kit required for these heaters in Canada.
** Blower motor heat not included.
When using units with 20-, 24-, and 30-kw electric heaters, maintain a 1-in. clearance from combustible materials to discharge plenum and ductwork,
and maintain a distance of 36 in. from the unit. Use an accessory downflow base to maintain proper clearance on downflow installations.
Use flexible connectors between ductwork and unit to prevent transmission of vibration. When electric heater is installed, use heat resistant material
for flexible connector between ductwork and unit at discharge connection. Ductwork passing through unconditioned space must be insulated and
covered with vapor barrier.
ESTIMATED SOUND POWER LEVEL (dBA)
* Estimated sound power levels have been derived using the method described in the
1987 ASHRAE HVAC Systems & Applications Handbook,
Chapter 52, p. 52.7
