IMPORTANT: All terminals must be placed so that they remain at least
12" above the expected snow line. Local codes may have more specific
requirements, and must be consulted. Refer to the NFPA54 National Fuel
Gas Code and your local codes for all required clearances for venting.

Terminals, Air and Vent
depending upon local conditions.
6.
Locate the terminal so the vent exhaust does
not settle on building surfaces or other nearby
objects. Vent products may damage surfaces
or objects.
7.
If the boiler or water heater uses ducted
combustion air from an intake terminal located
on the same wall, see Figures 10 and 11 for
proper spacing and orientation.
If the vent termination is located in an area exposed
to high winds, an optional PVC tee (the same
diameter as the vent pipe) may be used. The tee'd
vent termination offers greater protection from wind
related operating issues.
3.3.2 Side Wall Combustion Air Terminal
The Bradford White side wall combustion air terminal
must be used when the heater takes air from a side
wall. (See Figure 9.) Contact Bradford White for
Figure 10. Minimum Venting Distance
AL29-4C termination fittings. Consider the following
when installing the terminal. (See Figure 9 and
Figure 10).
1.
Do not locate the air inlet terminal near a
source of corrosive chemical fumes (e.g.,
cleaning fluid, chlorine compounds, etc.).
2.
Locate the terminal so that it will not be subject
to damage by accident or vandalism. It must be
at least 7 feet ( 2.1 m) above a public walkway.
3.
Locate the combustion air terminal so that it
cannot be blocked by snow. The National Fuel
Gas Code requires that it be at least 12 inches
(30 cm) above grade, but the installer may
determine it should be higher, depending upon
local conditions.
4.
If the Brute is side-wall vented to the same wall,
locate the vent terminal at least 1 foot (0.3 m)
above the combustion air terminal.
5.
Multiple vent kits should be installed such that
