Venting; Venting Lengths And Components - Napoleon The Bayfield GDS25N Installation And Operating Instructions Manual

2.0 vENTINg

THIS HEATER USES A 4" EXHAUST / 7" AIR INTAKE VENT PIPE SYSTEM.
For safe and proper operation of the heater follow the venting instruction exactly. Deviation from the minimum
vertical vent length can create difficulty in burner start-up and/or carboning. Under extreme vent configurations,
allow several minutes (5-15) for the flame to stabilize after ignition. Vent lengths that pass through unheated
spaces (attics, garages, crawl spaces) should be insulated with the insulation wrapped in a protective sleeve to
minimize condensation. Provide a means for visually checking the vent connection to the heater after the heater
is installed. Use a firestop, vent pipe shield or attic insulation shield when penetrating interior walls, floor or
ceiling.
Risk of fire, maintain specified air space clearances to vent pipe and appliance.
NOTE: If for any reason the vent air intake system is disassembled; reinstall per the instructions provided
for the initial installation.

vENTINg LENgThS ANd COmpONENTS

Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Metal-Fab venting compo-
nents. Minimum and maximum vent lengths, for both horizontal and vertical installations, and air terminal locations for
either system are set out in this manual and must be adhered to. For Simpson Dura-Vent, Selkirk Direct Temp, American
Metal Amerivent and Metal-Fab follow the installation procedure provided with the venting components.
A starter adaptor must be used with the following vent systems and may be purchased from the corresponding supplier:
PART
Duravent
Amerivent
Direct Temp
SuperSeal
* For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the installation
procedure found on the website for your venting supplier.
For vent systems that provide seals on the inner exhaust flue, 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 heater flue 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 / flexible components with the following
termination kits: wall terminal kit GD175 (7-1/2" of venting included), or wall terminal kit GD176 (24" of venting included), or
1/12 to 7/12 pitch roof terminal kit GD110, 8/12 to 12/12 roof terminal kit GD111, flat roof terminal kit GD112 or periscope kit
GD180 (for wall penetration below grade) in conjunction with the appropriate venting components.
For optimum flame appearance and heater performance, keep the vent length and number of elbows to a
minimum. It is recommended that all horizontal runs have a minimum 1/4" rise per foot.
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.
Different venting manufacturer components must not be combined.
These vent kits allow for either horizontal or vertical venting of the heater. The maximum number of 4" flexible connections
is 3 horizontally or three vertically (excluding the heater and the air terminal connections). When terminating vertically,
the minimum vertical rise is 3 feet above the heater and the maximum vertical rise is 40 feet. Deviation from the minimum
vertical vent length can create difficulty in burner start-up and/or carboning. Use an adjustable pipe as the final length of
rigid piping to the heater for ease of installation.
Refer to the section applicable to your installation.
