The connection from the radiator duct flange to the ductwork should be heavy canvas, silicone or similar flexible material to prevent noise and vibration transmission. Sheet metal ductwork should be self-supporting. In general, the outlet duct should have an unrestricted area 150% greater than that enclosed by the radiator duct flange. The inlet air opening should be at least as large as the outlet but preferably 50% larger. If screens, louvers or filters are used, openings should be increased in size according to the recommendations given in the “Air Requirements, General” section. Ductwork should be designed to allow ease of service in the event the radiator would have to be removed.

Air inlet and outlet locations should be chosen to prevent air recirculation inside or outside the enclosure. Consideration should also be given to prevailing winds, facing inlets into the expected winds and outlets on the downwind side where possible. Inlets and outlets should be located where they will not be blocked by accumulated snow or any other obstruction. Keep in mind that the exhaust air of larger units is both high-volume and high velocity. It may be accompanied by a high sound level and should be directed away from areas that may be occupied by people or animals.

Be sure to design any temperature controlling louvers so that inlet air is not restricted to the point that pressure inside the building is reduced. Low pressure can cause pilot lights on gas fired appliances to be extinguished or problems with the building ventilation system.

Bringing large quantities of winter air into a building can waste building heat and even result in frozen water pipes in normally heated spaces. An arrangement as shown in Figure 4-9 using thermostatic controls can eliminate such problems and allow recovery of engine heat to supplement the building heating system. For cold outdoor ambients, louvers to the exterior would be closed, with those to the interior open. Controls would be set to reverse the condition for warm outdoor temperatures.

4.8 Remote Radiator Cooling

If the generator set is located in an area into which it is difficult to bring the volume of air required to cool the radiator, such as a basement, a remote radiator can be mounted outside the building. See Figure 4-10.

The top of the remote radiator must be at the highest point in the system to function properly. The fan motor is connected to the generator output and will run when the generator is operating. The radiators can be set up for either horizontal or vertical air discharge.
