Horizontal Vent Termination

• Terminate at least 300mm (12") above

grade or above snow line.

• Terminate at least 2.1m (7') above a pub-

lic walkway, 1.8m (6') from the combus-
tion air intake of any appliance, and 0.9m
(3') from any other building opening, gas
utility meter, service regulator etc.

• Terminate at least 0.9m (3') above any

forced air inlet within 3m (10'), 0.3m (1')
below, 0.3m (1') horizontally from or 0.3m
(1') 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" downwards

for every 300mm (12") towards the termi-
nation.

• The integrated condensate collector must

be used for vertical runs in excess of
0.9m (3'). Remove the cap from the col-
lector prior to attaching the drain line.

• In the Commonwealth of Massachusetts

a carbon monoxide detector is required
for all side wall horizontally vented gas
fuel equipment.  Please refer to Technical
Bulletin TB 010606 for full installation in-
structions.

• Connect the vent pipe firmly so that it will prevent

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 dam-
age from snow falling off of roofs.

• Support the vent pipe with hangers at a minimum

of every 7'.

• 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 300mm (12") above grade or

snow line.

• Terminate at least 2.1m (7') above a public

walkway.

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.

• 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 sub-

stances near the vent terminal.

• Slope the vent pipe 1/4" for every 300mm (12")

either towards the horizontal termination or to-
wards the integrated condensate collector.

When using the condensate collector, create a

trap in the drain line and pre-charge it with water
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.
