The following formula can be used to determine the maximumheater rating per the definition of unconfined space:BTU/HR = (L1+L2) Ft x (W) Ft x (H) Ft x 100050Consider two connecting rooms with an open area between,with the following dimensions:( See Fig. 2, Example)L1=15-1/2 Ft., L2=12 Ft., W=12 ft., H=8Ft50=52800 BTU/HRIf there were a door between the two rooms the calculation wouldbe based only on the room with the heater.BTU/HR=(15-1/2) x (12) x (8) x 100050=29760 BTU/HR7FIGURE 2.FIGURE 2.FIGURE 2.FIGURE 2.FIGURE 2.When installing the appliance directly on carpeting, tile or other combustibleWhen installing the appliance directly on carpeting, tile or other combustibleWhen installing the appliance directly on carpeting, tile or other combustibleWhen installing the appliance directly on carpeting, tile or other combustibleWhen installing the appliance directly on carpeting, tile or other combustiblematerial, other than wood flooring, the appliance must be installed on amaterial, other than wood flooring, the appliance must be installed on amaterial, other than wood flooring, the appliance must be installed on amaterial, other than wood flooring, the appliance must be installed on amaterial, other than wood flooring, the appliance must be installed on ametal or wood panel extending the full width and depth of the appliance.metal or wood panel extending the full width and depth of the appliance.metal or wood panel extending the full width and depth of the appliance.metal or wood panel extending the full width and depth of the appliance.metal or wood panel extending the full width and depth of the appliance.FIGURE 3.
