Minimum Venting Requirements - Napoleon L38N Installation Manual

WARNING
!
• Risk of fi re. Maintain specifi ed air space clearances to vent pipe and appliance.
• If venting is included with spacers, the vent system must be supported every 3'(0.9m) for both vertical and
horizontal runs. Use support ring assembly W010-0067 or equivalent non-combustible strapping to maintain
the minimum clearance to combustibles for both vertical and horizontal runs. Spacers are attached to the
inner pipe at predetermined intervals to maintain an even air gap to the outer pipe. This gap is required
for safe operation. A spacer is required at the start, middle, and end of each elbow to ensure this gap is
maintained. These spaces must not be removed.
This appliance uses a 5" (127mm) exhaust / 8" (203.2mm) air intake vent pipe system. Refer to the

You may reduce the appliance from 5"/8" venting to 4"/7" venting for horizontal and vertical rise applications.
Vent Starter Adapter Part
Reducing must be done right off of the appliance and a new firestop spacer (W010-3440) will be required.

For vent systems that provide seals on the inner exhaust fl ue, only the outer air intake joints must be sealed using
a red high temperature silicone (RTV). This same sealant may be used on both the inner exhaust and outer intake
vent pipe joints of all other approved vent systems except for the exhaust vent pipe connection to the appliance
fl ue collar which must be sealed using the black high temperature sealant Mill Pac.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with the
following termination kits: wall terminal kit GD422-1, GD422R-1, or 1/12 to 7/12 pitch roof terminal kit GD410,
8/12 to 12/12 roof terminal kit GD411, fl at roof terminal kit GD412 or periscope kit GD401 (for wall penetration
below grade). With fl exible venting, in conjunction with the various terminations, use either the 5 foot (1.5m) vent
kit GD420 or the 10 foot (3.1m) vent kit GD430.
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)
