Clearance Chart:
For safe and efficient operation, maintain at least the following
minimum clearances at all times (See Fig. 1):
Bottom of Heater to Finished Floor:
• Front Inlet Models: (max 250 watts per foot)
- May be installed on floor if under 250 watts per foot.
However, for best performance, install bottom of heater
approximately 3 inches (76 mm) off floor. For models 250
watts per foot or more, bottom of units must be mounted at
least 2” off floor.
• Bottom Inlet Models:
- 100-250 watts per foot – 2 inch (51 mm)
Top of Heater to Ceiling (all models):
- Minimum 36 inches (914 mm)
Top of Heater to Bottom of Drapes (See Example 2):
- Minimum 6 inches (152 mm)
IMPORTANT NOTE:
Certain fabrics and vinyl materials (such
as vinyl blinds) may become damaged by the heated air from
the heater and should not be installed above the heater.
Front of Heater to Full Length Drapes (See Example 1):
- Minimum between bottom of drapes and floor – 2-1/2 inches
(64 mm)
- Minimum between top of drapes and ceiling – 1/2 inch (13
mm)
- Minimum between front of heater and nearest fold of drape –
2 inches (51 mm)
Top of Heater to Bottom of Window Sill:
- Minimum 12 inches (305 mm)
