High Efficiency Heat
Section Condensate
Drain
A unit with a high efficiency, condensing gas heat section requires a condensate drain
from the vent area. Depending on the heat section size, there are either one or two,
1/2” PVC connections. See FIGURE 29A, page 57 for drain connection locations.
Downstream from the trap, the condensate drain from the heat section may be con-
nected to a sanitary drain within the building if permitted by code. (Condensate from
the heater has a ph of 6 and is not harmful to a sanitary drain. NOTE: Actual ph may
vary ±1 depending upon fuel and combustion air.)

Combustion Air and Venting (cont’d)
If local code requires 4-ft (1.2M) vertical clearance between the flue outlet and the
fresh air intake of the heating system or the building, install an optional vertical vent.
The option package includes the bird guard for covering the vent outlet. The Schedule
40 PVC or CPVC vent pipe is field supplied. The vent pipe should be the same diam-
eter as the vent outlet. NOTE: In Canada, all PVC vent pipe must be approved to ULC
S636.
Option CC4 for units with one high-efficiency heat section includes one bird guard, P/N
221215, and two #10x1/2” Teks, P/N 37661, for attaching the guard.
Option CCD4 for units with dual high-efficiency heat sections includes two bird guards,
P/N 221215, and four #10x1/2” Teks, P/N 37661, for attaching the guards.
