Note 1 Ratings:
• All ratings above are based on sea level.
• Altitude ratings: Reduce maximum capacity by 4% per 1,000 feet above sea level.
— Example: The maximum “B”-tube/head capacity at 5,000 feet altitude is 560,000 Btuh instead of 700,000, a 20% reduction.
Positive overfire pressure effects:
• Maximum burner input decreases with increasing overfire pressure.
• Assume a reduction in maximum burner input of approximately 5% at 0.1 inches w.c. and 10% at 0.2 inches w.c.
• You will have to increase the air damper opening to compensate for the increased pressure.
• Follow the procedures given in this manual to check combustion with instruments to determine the correct air setting.
• Never fire at a higher overfire pressure than recommended by the appliance manufacturer.
Note 2 Use air settings for starting only. Adjust air setting, if necessary, after performing combustion testing (see page 18).
Prepare burner and components
Do not install or operate the burner if any component is damaged
or if burner does not comply with the specifications of Table 1a
and other guidelines in this manual.
Combustion head/air tube configurations
• 601GAS burners are supplied with one of three tubes and one of three
heads, determined by firing rate and appliance application. Tubes are
specified as one of three configurations (B, C or D). Heads are specified
as type 11, 12, 21, 22, 31 or 32.
