Dimensions in [ ] are in millimeters.2. Center of gravity.3. Direction of airflow.4. On vertical discharge units, ductwork to be attached to accessory roof curb only. For horizontal dis-charge units, field-supplied flanges should be attached to horizontal discharge openings, and allductwork should be attached to the flanges.5. Minimum clearance (local codes or jurisdiction may prevail):a. Between unit, flue side and combustible surfaces, 48 inches. (18 in. when using accessory fluedischarge deflector.)b. Bottom of unit to combustible surfaces (when not using curb), 1 inch.Bottom of base rail to combustible surfaces (when not using curb) 0 inches.c. Condenser coil, for proper airflow, 36 in. one side, 12 in. the other. The side getting the greaterclearance is optional.d. Overhead, 60 in. to assure proper condenser fan operation.e. Between units, control box side, 42 in. per NEC (National Electrical Code).f. Between unit and ungrounded surfaces, control box side, 36 in. per NEC.g. Between unit and block or concrete walls and other grounded surfaces, control box side, 42 in.per NEC.h. Horizontal supply and return end, 0 inches.6. With the exception of the clearance for the condenser coil and combustion side as stated in notes5a, b and c, a removable fence or barricade requires no clearance.7. Units may be installed on combustible floors made from wood or Class A, B, or C roof coveringmaterial if set on base rail.8. The vertical center of gravity is 1′-6″ [457] up from the bottom of the base rail.BOTTOM POWER CHART, THESE HOLES REQUIRED FORUSE WITH ACCESSORY PACKAGES — CRBTMPWR001A00THROUGH CRBTMPWR004A00*Select either 3 / 4″ or 1 1 / 4″ for power, depending on wire size.†Select either 1 / 2″ or 3 / 4″ for gas depending on gas connection.THREADEDCONDUIT SIZE WIREUSE REQUREDHOLE SIZES (MAX.)1/ 2″ 24 V 7/ 8″ [22.2]3/ 4″ Power* 1 1/ 8″ [28.4]1 1/ 4″ Power* 1 3 / 4″ [44.4]1 / 2″ NPT Gas† 1 1/ 4″ [31.8]3 / 4″ NPT Gas† 1 5/ 8″ [41.3]
