Clearance Chart:
For safe and efficient operation, maintain at least the following
minimum clearances at all times:
Bottom of Heater to Finished Floor:
• Front Inlet Models: (max 600 watts per foot)
- May be installed on floor. However, for best performance,
install bottom of heater approximately 3 inches (76 mm) off floor.
• Bottom Inlet Models:
- 100-250 watts per foot – 1-3/4 inch (44 mm)
- 375-750 watts per foot – 3 inches (76 mm)
Top of Heater to Ceiling (all models):
- Minimum 36 inches (914 mm)
Top of Heater to Bottom of Drapes Above Heater:
- Minimum 12 inches (305 mm)
