Planning your space: Dimensions are height × width × depth in inches, for the listed model sizes. Size codes are the numeric suffix in the full Lennox model number. Cabinet measurements exclude installation clearances, pads, optional risers, piping and accessories; mounting feet may extend beyond the cabinet. Furnaces are measured upright and exclude the coil, filter cabinet and ductwork. RTB will confirm the exact equipment revision and required space before installation.
The right match makes the difference.
Published ratings depend on capacity and the exact matched indoor/outdoor equipment. RTB verifies sizing, AHRI ratings, local suitability, availability, and installation details before quoting. Prices and labor coverage are supplied in your RTB proposal. EL18KSLV regional availability must be confirmed with RTB’s distributor.
