10.6 MULTIPLE VENTING
H15.6
COMMON VENTING IS PROHIBITED!!
If two of these furnaces are to be installed in close proximity, the combustion air intake and exhaust
terminations may be installed as shown in Figures 12 and 13.
IMPORTANT
:
WHEN INSTALLING MULTIPLE FURNACES IN CLOSE PROXIMITY, EACH REQUIRES
DEDICATED COMBUSTION AIR AND EXHAUST VENTING.
If more than two furnaces are being installed in close proximity, each additional combustion air intake and
exhaust termination set shall not terminate less than 12 in (305mm) apart. Note: Canadian installations of
120000 Btu/hr require 3 ft (915mm).

Avoid locating the terminal in locations where dripping condensate may cause problems such as sidewalks,
patios, above planters, near windows where exhaust gases may cause fogging, icing, etc.
Avoid locating the termination too close to shrubs and other vegetation. The condensate may stunt or kill them.
Caulk all cracks, seams or joints within a 6 foot (1.8m) radius of the termination.
Do not terminate under a deck unless there is adequate clearance to prevent damage from the
fl
ue gases.
A termination may be located at the end of a patio deck. Piping running beneath the deck must be suitably
insulated and suspended in a manner to prevent condensate from collecting and freezing.
When locating vent terminations, consideration must be given to prevailing winds, location, and other
conditions which may cause recirculation of the combustion products of adjacent vents.
IMPROPER LOCATION OR INSTALLATION CAN RESULT IN STRUCTURAL DAMAGE TO
THE BUILDING, DAMAGE TO THE EXTERIOR FINISH OF THE BUILDING, OR MAY ALLOW
RECIRCULATION OR FREEZING OF THE FLUE GASES ONTO OR INTO THE COMBUSTION
AIR INTAKE.
MOISTURE IN THE FLUE GASES CONDENSES AS IT LEAVES THE TERMINALS. THIS
MOISTURE CAN FREEZE ON EXTERIOR WALLS, SOFFITS, AND OTHER NEARBY
OBJECTS. SOME DISCOLORATION IS TO BE EXPECTED.
CAUTION
!
!
The vent terminal should be located no fewer than 3 feet (.9m) from an inside corner formed by two exterior walls.
Recommended clearance for overhangs is a minimum of 1 foot (.3m) vertically for each foot horizontally up to
6 feet (1.8m).
Any adjacent painted surfaces should be in good condition; no cracks, peeling paint, etc. If wooden surfaces that
may be periodically exposed to
fl
ue gases are present, consider treating with a sealer
.
H3.15
RECIRCULATION OF FLUE GASES MAY OCCUR CAUSING THE INTAKE PIPE TO
FREEZE SHUT DURING COLD WEATHER OPERATION IF THE VENTING SYSTEM IS NOT
INSTALLED PER THESE GUIDELINES.
WARNING
