*Add Suffix: (P)Packaged water boiler less tankless heater, (PT)Packaged water boiler with tankless heater, (PPT)Packaged water boiler with provision for tankless heater, (PZ)Packaged steam boiler less

tankless heater, (PZT)Packaged steam boiler with tankless heater.

†Ratings apply to the use of light oil at 140,000 Btu per gallon, and a .02% draft (negative pressure) over the fire.

‡The net I=B=R output ratings shown are based on an allowance for piping and pickup of 1.15 (water) or 1.33 (steam). D.O.E. capacity gross output is divided by the allowance to obtain net rating. The manufacturer should be consulted before selecting a boiler for unusual piping and pickup requirements such as intermittent system operation, extensive piping, etc.

§Nominal clay tile liner dimensions.

** Tankless heater rating based on intermittent draw.

¶Water boiler models TR-30, TR-40, TR-50, TR-60 and TR-70 have two firing rates. The boiler is factory shipped at the lower firing rate. To obtain the higher firing rate, refer to the Intrepid boiler installation instructions for the appropriate field adjustments.

#I.B.R. gross output

ΔCollar is oblong, will fit 6" diameter nominal connector.

NOTE: All boilers under 300,000 Btuh input are tested and rated for capacity under the U.S. Department of Energy (D.O.E.) Test Procedures for Boilers.å
