Notes:
- Firing rates based on altitudes to 2000ft. above sea level.
* For firing rates at higher altitudes, consult factory. - Gas input based on natural gas at 1,000 Btu/cu.ft. and 0.60 gravity
- Oil input based on 140,000 Btu/gal. on S1/LNS1 Series and 150,000 Btu/gal. on S1E series
- Boiler overall efficiency of 80% estimated. Industrial Combustion does not guarantee overall boiler efficiency.
- Furnace pressure and furnace dimensions and required NOx emissions may allow higher firing rates than shown above, consult factory.
- Shipping weight is only an estimate
- Motor horsepower based off of standard design backpressure rating. Consult factory for review and comparison to your application.
