downwind from air supply inlet to prevent exhaust recirculation.
5. Under certain wind conditions, some building materials may be a ected
by  ue products expelled in close proximity to unprotected surfaces.
Sealing or shielding of the exposed surfaces with a corrosion resistant
material (such as an aluminum sheet) may be required to prevent staining
or deterioration.
6. The minimum vent height should extend at least 3 feet (0.9 m) above the
roof, or at least 2 feet (0.6 m) above the highest part of any structure within
10 feet of the vent.
7. If the exhaust vent terminates within 10 ft (3 m) horizontally of the air inlet,
the exhaust vent must be at least 4 ft (1.2 m) above the inlet. Dimensions
provided are minimum, and may or may not be su cient for conditions at
a speci c job site.
8. To prevent the possible re-circulation of  ue gases, the vent designer
must take into consideration such things as prevailing winds, eddy zones,
building con gurations, etc. Fulton cannot be held responsible for the
e ects such adverse conditions may have on the operation of the boilers.
9. It is important to locate the exhaust duct in such a way that it does
not become blocked due to snow, ice, and other natural or man-made
obstructions.
Removing an Existing Boiler
When an existing boiler is removed from a common venting system, the
common venting system is likely to be too large for proper venting of the
appliances remaining connected to it.
At the time of removal of an existing boiler, while the other appliances remaining
connected to the common venting system are not in operation, the following
steps should be followed with each appliance remaining connected to the
common venting system placed in operation:
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch and
determine that there is no blockage or restriction, leakage, corrosion or
other de ciency, which could cause an unsafe condition.
3. Insofar as is practical, close all building doors and windows and all doors
between the space in which the appliances remaining connected to the
common venting system are located and other spaces of the building.
Turn on clothes dryers and any appliances not connected to the common
venting system. Turn on any exhaust fans, such as range hoods and
bathroom exhausts, so they will operate at maximum speed. Do not
operate a summer exhaust fan. Close  replace dampers.
4. Place the appliance being inspected in operation. Follow the lighting
instructions. Adjust the thermostat so that the appliance will operate
continuously.
