Condensate Drain - NTI Matrix M100 Installation And Operating Instructions Manual

Matrix Installation and Operation Instructions

4.0 CONDENSATE DRAIN

This unit produces water as a product of combustion. Much of this water condenses on the heat exchanger and in the venting
system. All exhaust piping must be on a slope back to the boiler ¼" per linear foot of vent. Steps must be taken to ensure that
condensate does not collect in the venting system. Condensate must be drained from the boiler into a household drain.
WARNING
FAILURE TO PROPERLY CONNECT THE CONDENSATE LINE WILL CAUSE COMBUSTION GASES TO
ENTER THE ROOM, POSSIBLY CAUSING SERIOUS INJURY TO OCCUPANTS OR DEATH.
Note: check with your municipality, or local gas company to determine if disposal
of combustion condensate is permitted.
condensate must be neutralized prior to entering a drain.
The following are important notes that must be taken into consideration when
constructing the condensate system:
DO NOT run condensate line outside. A frozen or blocked drain will cause the
o
condensate to fill the combustion chamber. This will result in a no heat
condition, as the unit will shut down, and damage to the flame sensor, and
components can occur.
NEVER use copper, steel, or galvanized piping in the construction of the
o
condensate system (condensate is very corrosive and will wrought most
metals).
When a condensate pump is used or required, select a pump that is designed
o
for residential furnaces.
