Vent Information and Diagrams

A. Vent Guidelines
WARNING!
Fire Risk/Asphyxiation! This appliance requires
the specifi ed pipe for operation. Incorrect pipe may cause spill-
age, condensation and overheating.
• Follow pipe manufacturer's installation guidelines when
installing the appliance.
Model GATEWAY is approved to use Duravent 4-inch (102
mm) diameter B-type vent for installations that terminate
vertically. The PV-Flex Series vent pipe is approved for
use in installations that terminate horizontally. This pipe
is tested and listed as an approved component of the
fi replace.
This model may also use single wall rigid or fl exible gas
vent IF and ONLY IF the vent system is installed within
non-combustible construction such as a masonry chim-
ney. The same diameter noted above for B-type vent
must be used for single-wall vent (see Figure 5.1).
For B-type vent the clearance to combustibles is 1-inch all
around the pipe. Follow vent manufacturers REQUIRED
clearances. For PV-Flex the clearances are 1-1/2 in. top
and 1 in. sides and bottom when venting horizontally
and 1 in. on all sides when passing vertically through
combustible materials.
NOTE: Due to the positive pressure within the Gateway
venting system, when using PV-FLEX use a 1/2 in. bead of
HIGH TEMPERATURE silicone caulk on ALL pipe ends and
connectors throughout the vent run to ensure a completely
sealed system.
Vent pipes must be installed within the conditioned house
envelope in order to avoid fl ue gas condensation. Verti-
cal termination through an unconditioned attic space is
permissible.
The fl ame and ember appearance may vary based on the
type of fuel burned and the venting confi guration used.
WARNING!
Fire Risk/Explosion/Asphyxiation!
connect this gas appliance to a chimney fl ue serving a
separate solid-fuel or gas burning appliance.
• Vent this appliance directly outside.
• Use separate vent system for this appliance.
May impair safe operation of this appliance or other appli-
ances connected to the fl ue.
WARNING! Risk of Fire or Explosion! Insulation and
other combustibles must not infringe on clearances.
• ALWAYS maintain specifi ed clearances around venting
and fi restop systems.
• Install fi restops as specifi ed.
Failure to keep insulation or other material away from vent
pipe may cause fi re.

to these specifi cations. Appliance performance will suffer if
specifi cations are not followed.
Consult Local Building Code Offi cials and Codes for
proper vent system installations.

The following fi gures are examples of approved venting
conditions. Venting downward (3 feet maximum) is ap-
proved, to allow venting below the fl oor. However, only
one downward section is allowed for up to, but not ex-
ceeding 3 feet maximum.
Note: It is always better to fi rst attach a straight section of
vent to the unit before attaching an elbow. Avoid using elbows
in the vent system if possible.
Continue to add vent components, until the vent run is
completed.
See Section 8 for instructions regarding assembly of vent
sections and securing vent sections.
