Typical Vent Installations - Napoleon HDX40NT-1 Mode D'emploi

For optimum fl ame appearance and appliance performance, keep the vent length and number of elbows to a
minimum.
The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify
that it is unobstructed and undamaged.
Rigid and fl exible venting systems must not be combined. Different venting manufacturer components must
not be combined.
These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontal
run is 20 feet (6.1m). The maximum allowable vertical vent length is 40 feet (12.2m). The maximum number of vent
connections is two horizontally or three vertically (excluding the appliance and the air terminal connections) when
using fl exible venting.
Horizontal runs may have a 0" (0mm) rise per foot/meter however for optimum performance it is recommended
that all horizontal runs have a minimum 1/4" (6.4mm) rise per foot/meter using fl exible venting. For safe and proper
operation of the appliance, follow the venting instructions exactly.
A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single family
dwellings and serves both dwellings. Local codes or regulations may require different clearances.
Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1¼"
(31.8mm) air gap all around between the inner liner and outer liner is required for safe operation.
