Condensate Drain; Installing Gas Piping - NTI Trinity Ti 100 Installation And Operation Instructions Manual

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.
Note: check with your municipality, or local gas company to determine if disposal of combustion condensate is permitted. In the
State of Massachusetts the 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 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 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 for residential furnaces.
Warning:
The condensate drain kit supplied
with each boiler is susceptible to
flooding if the drain hose exiting
the kit is lengthened or inserted
into a drain. If additional length
is required, do not use the drain
kit provided, instead fabricate a
15" trap using tubing suitable for
condensate disposal.
15"min.
Failure to properly connect the condensate
line will cause combustion gases to enter the
room, possibly causing serious injury to
occupants or death.
