Wall Control - Bryant HRVBBLHA Installation Instructions Manual

Step 5.—Condensate Drain
To connect condensate drain, proceed as follows:
1. Insert sleeved grommets into bottom of unit using the
gasket washer and nut (See Fig. 10).
2. Cut two sections of plastic tubing, about 12" long and
attach them to each drain.
3. Join the two short sections of plastic tubing to the "T"
connector and the main tube as shown.
4. Make a loop in the tubing below the "T" connector to
create a trap to prevent sewer gases from entering the
ventilation system (See Fig. 10).
5. Connect unit drain to building's main drain. Provide
slight slope from unit for run ---off.
Step 6.—Locate and Install Exterior Hoods
IMPORTANT: To prevent condensation problems, insulated
flexible ducts are required on both fresh ---air inlet and
exhaust---air outlet ducts connecting between HRV and
exterior wall.
Fresh ---air intake and stale ---air exhaust must be separated
by at least 6 ft. Fresh ---air intake must be positioned at
least 10 ft. from nearest dryer vent, furnace exhaust,
driveway, gas meter, or oil fill pipe. Fresh ---air intake must
be positioned as far as possible from garbage containers
and potential chemical fumes. When possible, it is advised
to locate the intake and exhaust hoods on same side of
house or building. The intake and exhaust hoods should
never be located on interior corners or in dead air pockets
(See Fig. 8). Both intake and exhaust hoods must be 18 in.
from ground and at least 12 in. above anticipated snow
level.
After selecting proper hood locations, make appropriate
size hole through exterior wall, pass flexible duct through
hole and insert hood tube into duct. Tape duct vapor barrier
tightly around hood tube and insert assembly back into wall
and fasten securely.
