Capacity Chart developed using ANSI Z21.69 Specifications
Capacity was determined under the test conditions specified in ANSI Z21.69·CSA 6.16
The capacity at 0.21 inches water column (50 Pa) pressure can be determined by multiplying by
0.632.
For capacities under conditions other than the noted above, the manufacturer or serving gas
supplier should be contacted.
