As with most heating systems, air borne particles and odors in the room may be drawn into the heating system and oxidized. Since the room air passes directly through the hot brick core of the ETS heater, the oxidation process will change the properties of these particles and odors. Odors can be amplified; thus, it is recommended not to operate the heating system if odors such as those from paints, varnishes, or chemicals are present in the air. Allow the area to be completely aired out before operating the heater.
As for air borne particles, after they have been oxidized they are expelled back into the room and may accumulate on the heater or other surfaces. Over time these particles may appear as a black residue commonly referred to as soot. High concentrations of air borne particles from such things as aerosols, dust, candles, incense, pet hair, high humidity, smoke, or cooking can contribute to poor indoor air quality and accelerate this process. To minimize the black residue build-up, clean the outer surface of the heater on a regular basis. Wash the cabinet, only when cool, with a nonabrasive household cleaner. Do not use scouring powders or furniture polish. Steffes recommends using Soft Scrub with Bleach ™ brand cleanser or an equal.
Regularly vacuum around all sides of the heater. Check the back of the heater to make sure no objects have fallen behind it and the grill area to make sure there isn't anything obstructing air flow. Check all sides of the heater to be sure the required clearances are not being violated.
NOTE: Objects should never be placed on top of the heater.
No additional routine maintenance is required; however, having a professional service technician clean the blower periodically will decrease the likelihood of undesirable blower noise due to dust accumulation.
