Maintenance and Cleaning
6
As with most heating systems, air borne particles in the room may be drawn into the heating system and oxidized. As
these air borne particles are expelled back into the room, they 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 contrib-
ute to poor indoor air quality and accelerate this process.
To minimize the black residue buildup, clean the outer surface of the heater on a regular basis. Wash the cabinet only
when cool with any liquid cleaner. Do not use scouring powders or furniture polish. Steffes recommends using "Soft
Scrub with Bleach" brand cleanser or its equal.
Regularly vacuum around all sides of the heater. Check the back of the heater to make sure no objects have fallen
behind it. Check all sides of the heater to be sure the required clearances are not being violated. Objects should never
be placed on top of the heater. No additional routine maintenance is required.
Describing The Heater's Display Panel
All operational functions of the heater are stored in the heater's microprocessor. These operational functions are
factory preset; however, they can be adjusted by the user or installer. All operational functions are accessed
through the heater's control panel. Typically, the user will only need to use this panel to adjust the room tempera-
ture; and, possibly, to set the brick core temperature if manual charge control is used.

TEMPERATURE and MODE Digits
Typically, these digits continuously display current room temperature and
one of the following brick core operating modes (Refer to the Advanced
Heater Operation section of this manual for more information):
C = (charge period) Off-peak time in which the heater is allowed
to store heat in its brick core. (See Figure 2)
P = (peak period) On-peak time in which the heater is not
allowed to store heat in its brick core. (See Figure 3)
A = (anticipated peak period) Used only in certain utility pro-
grams. It is an alternative method of storing heat in the
heater's brick core. (See Figure 4)
