13Matrix Installation and Operation Instructions4.0 CONDENSATE DRAINThis unit produces water as a product of combustion. Much of this water condenses on the heat exchanger and in the ventingsystem. All exhaust piping must be on a slope back to the boiler ¼” per linear foot of vent. Steps must be taken to ensure thatcondensate does not collect in the venting system. Condensate must be drained from the boiler into a household drain.Note: check with your municipality, or local gas company to determine if disposalof combustion condensate is permitted. In the State of Massachusetts thecondensate must be neutralized prior to entering a drain.The following are important notes that must be taken into consideration whenconstructing the condensate system:o DO NOT run condensate line outside. A frozen or blocked drain will cause thecondensate to fill the combustion chamber. This will result in a no heatcondition, as the unit will shut down, and damage to the flame sensor, andcomponents can occur.o NEVER use copper, steel, or galvanized piping in the construction of thecondensate system (condensate is very corrosive and will wrought mostmetals).o When a condensate pump is used or required, select a pump that is designedfor residential furnaces.WARNINGFAILURE TO PROPERLY CONNECT THE CONDENSATE LINE WILL CAUSE COMBUSTION GASES TOENTER THE ROOM, POSSIBLY CAUSING SERIOUS INJURY TO OCCUPANTS OR DEATH.Figure 4.1 Condensate Drain PlumbingCondensateDrain FromBoilerDrain must beopen to allowoverflow ifblockedDrain mustinclude trapNipple mustbe cut.
