Page 4 SLP98DFV Gas Furnace The S LP98DFV category IV g as furnace is equipped with a variable−capacity , variable−s peed integrated control. This control ensures compatibility with the Lennox icom- fort T ouch thermostat and Harmony III zone contr ol system, as well as a thermost at whi ch provides humidity control.
Page 5 Installed in Combination with a Cooling Coil When this furnace is used wi th cooling units, it shall be installed in parallel with, or on the upstream side of, cooling units to avoid condensation in the heating compartment.
Page 6 General W ARNING Product contains fiberglass wool. Disturbing the insulation in this product during inst allation, maintenance, or repair will expose you to fiberglass wool. Breathing this may cause lung cancer . (Fiberglass wool is known t o the St ate of Cal- ifornia to cause cancer .
Page 7 NOTE − The 1/2 hp blower motor used in some SLP98DFV unit is equipped with three flexible legs and one rigid leg. Th e rigid leg is equipped with a shipping bolt and a flat white plastic washer (rather than the rubber mounting grommet used with a flexible mounting leg).

Page 47 Proper Combustion Furnace should operate minimum 15 minutes with correct manifold pressure and gas flow rate before checking com- bustion. T ake combustion sample beyond the flue outlet and comp are to the tables below . The maximum carbon monoxide reading should not exceed 50 ppm.
Page 48 T emperature Rise Af te r the furnace has been started and supply and return air temperatures have been allowed to st abilize, check the temperature rise with the unit operating at 100 percent fir- ing rate. If necessary , adjust the blower speed to maintain the temperature rise within the range shown on the unit nameplate.
