Venting Requirements - Napoleon Ascent Serie Manuel D'installation

WARNING
!
• Risk of fi re. Maintain specifi ed air space clearances to vent pipe and appliance.
• 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
section applicable to your installation.
For safe and proper operation of the appliance follow the venting instructions exactly. Deviation from the
minimum vertical vent length can create diffi culty in burner start-up and/or carboning. Under extreme vent
confi gurations, allow several minutes (5-15) for the fl ame to stabilize after ignition. Although not a requirement,
it is recommended for vent lengths that pass through unheated spaces (attics, garages, crawl spaces) be
insulated with the insulation wrapped in a protective sleeve to minimize condensation. Provide a means for
visually checking the vent connection to the appliance after the appliance is installed. Use a fi restop, vent pipe
shield or attic insulation shield when penetrating interior walls, fl oor or ceiling.
The vent terminal may be painted with a high temperature paint to match exterior colours. Use an outdoor paint
suitable for 400°F (200°C). Application and performance of paint is the consumer's responsibility. Spot testing is
recommended.
note:
If for any reason the vent air intake system is disassembled; reinstall per the instructions provided for the
initial installation.
This appliance must be installed with a continuous connection of exhaust and air intake vent pipes. Utilizing
alternate constructions, such as a chimney as part of the vent system, is not permitted.
Use only Wolf Steel, Metal-Fab, BDM, Simpson Dura-Vent, or Selkirk Direct Temp venting components.
Minimum and maximum vent lengths, for both horizontal and vertical installations, clearances from vent pipes to
combustibles and air terminal locations as set out in this manual apply to all vent systems and must be adhered
to. For Metal-Fab, BDM, Simpson Dura-Vent, or Selkirk Direct Temp, follow the installation procedure provided
with the venting components or on the website for your venting supplier.
A starter adaptor must be used with the following vent systems and may be purchased through Wolf Steel or
from the corresponding supplier listed below:

Connections made by means of an adaptor at the appliance, as well as the connection at the vent terminal must
be sealed. RTV sealant may be used on both the inner exhaust and outer intake vent pipe joints of all other ap-
proved 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.
For all vent systems is strongly recommend for all installations but required when power venting the appliance,
that the outer air intake joints are sealed using either high temperature silicone (RTV) or a suitable aluminum tape
that covers each joint in the vent system entirely around its circumference. This will ensure the best performance
in every application and avoids performance or condensation concerns that may occur in "tightly" constructed
homes, particularly those in cold climates.
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-2, ST58U-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.
