Placement - 3100/4100 Series

THIS PROCEDURE MUST BE PERFORMED BY A QUALIFIED TECHNICIAN.

WARNING

Risk of fire. Can cause injury or death.

Violation of the clearance requirements and/or failure to provide proper ventilation can cause improper operation of the system. Maintain the placement and clearance requirements as specified and provide ventilation as necessary.
Failure to maintain room temperature in the mechanical room of 85°F/29°C or less may result in equipment damage. Thermostatically controlled ventilation should be provided if the temperature in this area exceeds 85°F/29°C.
Moving the system after install may result in equipment damage. Do NOT move system from original installed location.

The physical dimensions of the Comfort Plus, along with the clearances required, MUST be taken into consideration when choosing its location within a structure. (See Clearance Requirements and system dimensions.)

The best installation location for this system is in a space requiring heat so some amount of the heating requirements can be satisfied through static dissipation from the warm outer panels. In situations where the Comfort Plus is not installed in an area it is intended to heat (i.e. storage closet), it is important to account for the heat lost through static dissipation by making proper adjustments when sizing the system. Standby heat dissipation of up to 2.5kW can be experienced in normal operation. Room air should be maintained at less than 85°F/ 29°C.

If ventilation is needed, it can be provided by installing a 24” x 24” opening into the area where the Comfort Plus is located. In addition, a 6” x 6” non-closing type register can be cut into the return air duct of the furnace to minimize heat build-up in the room. This register must be installed in a manner that ensures the air drawn into the Comfort Plus passes through the filter first (see below).

In addition to the physical space requirements, the weight of the Comfort Plus must be taken into consideration when selecting the installation surface. A level concrete floor is the best installation surface on which to place the system, but most well supported surfaces are acceptable. If unsure of floor load capacity, consult a building contractor or architect.

NOTE: Special requirements must be considered if placing the system in a garage or other area where combustible vapors may be present. Consult local, state, and national codes and regulations to ensure proper installation. An 18" pedestal (Order Item #1301585) is available to elevate the system.
