The point from where the flue products exit the heater must be a minimum of four (4) feet below, four (4) feet
horizontally from or one (1) foot above any door, window or gravity inlet to a building. The top surface of the heater
shall be at least three (3) feet above any forced air inlet, or intake ducts located within ten (10) feet horizontally.
HIGH WIND CONDITIONS (OUTDOOR UNITS ONLY)
In areas where high winds are frequent, it may be necessary to locate the heater a minimum of 3' from high
vertical walls, or install a wind break so the heater is not in direct wind current.
In areas of daily high winds, it may be necessary to replace the outdoor stackless top with a stack adapter in
combination with a wind resistant/weather proof outdoor stack. See illustration below.
Fig. # 8245.1
The outdoor stack serves the same function as the
low profile stackless top and should be installed in
accordance with the same clearance requirements.
