Horizontal Vent Termination
• Terminate at least 12" (300mm) above
grade or above snow line.
• Terminate at least 7' (2.1m) above a public
walkway, 6' (1.8m) from the combustion air
intake of any appliance, and 3' (0.9m) from
any other building opening, gas utility me
-
ter, service regulator etc.
• Terminate at least 3' (0.9m) above any forced
air inlet within 10' (3m), 1' (0.3m) below,
1' (0.3m) horizontally from or 1' (0.3m)
above any door, window, or gravity air inlet
into any building per National Fuel Gas
Code ANSI Z223.1/NFPA 54.
• Slope the horizontal vent 1/4" (6mm)
downwards for every 12" (300mm) towards
the termination.
• The integrated condensate collector must be
used for vertical runs in excess of 3' (0.9m).
Remove the cap from the collector prior to at
-
taching the drain line.

In the Commonwealth of Massachusetts a car
-
bon monoxide detector is required for all side
wall horizontally vented gas fuel equipment.
Please refer to Technical Bulletin TB 010606
for full installation instructions.

Drain condensate
according to
local codes.
• Connect the vent pipe firmly so that it will pre
-
vent exhaust gases from leaking.
• Steam or condensed water may drip out of the
vent terminal. Dispose of this condensed water
according to local codes and in order to prevent
injury or property damage.
• If this product will be installed in an area where
snow is known to accumulate,protect the vent
termination from blockage by snow drifts or
damage from snow falling off of roofs.
• Support the vent pipe with hangers at a mini
-
mum of every 7' (2.1m).
• Make the vertical pipe as short as possible.
• Do not common vent or connect more than
one appliance to this venting system.
• Terminate at least 12" (300mm) above grade or
snow line.
• Terminate at least 7' (2.1m) above a public
walkway.
• Exceeding the maximum vent length is danger-
ous and may result in bad combustion.
• Install the vent terminal so that all exhaust is di-
rected to and all intake air is taken from outdoors.
• Do not store hazardous or flammable substanc
-
es near the vent terminal.
•
Slope the vent pipe 1/4" (6mm) for every 12"
(300mm) either towards the horizontal termination
or towards the integrated condensate collector.
When using the condensate collector, create a
trap in the drain line and pre-charge it with wa
-
ter to prevent exhaust gas leakage.
• Maintain the same vent pipe diameter all the
way to the end.
• Noritz Concentric vent pipe is approved for use
on this appliance with zero clearance to com
-
bustibles.
• Use only Noritz specified venting products.
WARNING
Be sure to do
CARBON MONOXIDE POISONING
Do not remove the cap from the condensate collector unless it is being used to drain
condensate. Without the cap in place, flue products could enter the living space.
