2.1.11 DRAIN TEE
Figure 8
: Drain “T” and Neutralizer Cartridge Installation
A drain line must be connected to the boiler condensate drain and to a tee installed in the vent pipe to collect and dispose of any
condensate that may occur in the boiler and vent system. The drain tee should be installed at the point where the flue turns vertical for
a roof top termination or as one of the first fittings in a horizontal flue that will terminate on a SIDEWALL. Ensure that horizontal portions
of the vent are properly sloped away from the appliance to allow condensate to be evacuated at the drain tee. Plastic drain tubing, sized
per
the vent manufacturer’s instructions, shall be provided as a drain line from the tee and from the boiler condensate line. The drain
tubing from the tee must have a trap provided by a 4” (10 cm) diameter circular trap loop in the drain tubing and the boiler drain shall be
normal with no loop and tied into the tee drain tubing with a tee at a point after the 4” loop and before the neutralizer. Prime the trap loop
by pouring a small quantity of water into the drain hose before assembly to the vent. Secure the trap loop in position with nylon ties. Use
caution not to collapse or restrict the condensate drain line with the nylon wire ties. The common condensate drain must be routed to the
condensate neutralization system or a suitable drain for the disposal of condensate that occurs in both the boiler and in the vent system.
Ensure that the drain from the condensate tee is not exposed to freezing temperature.
