The table above gives approximate burner capacities for combustion chambers with drafts from 0.05" wc to 0.1" wc and 41% induced
secondary air at 16 osi pressure, 45% at 20 osi pressure, 47.5% at 24 osi pressure and 50% at 32 osi pressure. If more draft is available,
maximum burner capacity can be increased.
Note: Capacities in these tables are based on No. 2 fuel oil with a gross heating value of 138,000 Btu/gallon. Capacities for other grade fuel
oils will vary based on their gross heating value.
