Draining the Condensate
In certain conditions, installations in
unconditioned space or having long
horizontal or vertical runs may accumulate
condensate.
In order to prevent condensate from
draining back into the blower, we
recommend a condensate tee and drain to
be installed in a horizontal vent section as
close as practical to the blower vent
connection.
Vertical Vent Termination
Minimum twelve (12) inches (30,5 cm)
Minimum twelve (12) inches (30,5 cm)

Maximum twenty-four (24) inches (61cm)above

window, etc.).

dryer or furnace area is considered to be a forced air
inlet.

Horizontal Vent Installation
Once the vent terminal location has been determined,
make a hole through the exterior wall to
accommodate the 3" or 4" vent pipe. Vent pipe must
exit exterior wall only.
Insert a small length of 3" or 4" vent pipe through the
wall and connect the coupling as shown.
Place the ½" mesh metal screen inside the terminal
fitting and connect it as shown to the vent pipe on the
exterior of the building.
Seal any opening around the vent pipe or fittings with
mortar or silicone caulk as shown.
Complete the rest of the vent pipe installation to the
water heater's vent connector fitting on the blower
outlet. If necessary support horizontal run as
previously mentioned.
Use silicone sealant at the point the vent connector
joins the blower assembly.
Condensate is known to be acidic; refer to
local, state (provincial) or federal codes
for proper handling methods.
