Page 19: Assembly Of Tube Sections
10.0) ASSEMBLY OF TUBE SECTIONS During field assembly of the heater body sections, the recommended procedure is as follows: 1. Before hanging heater sections, first determine the actual layout of the system (see Sections 7.0 & 8.0 for details). Consideration must also be taken for flue pipe, fresh air ducting, gas piping, clearances to combustibles, etc. -
Page 20: Assembly Of Extension Section
10.1 ASSEMBLY OF EXTENSION SECTION See typical assembly overview (Section 8.0) for typical complete assembly. Assemble additional extension sections as required for all systems. (See Sections 7.0, and 8.0 for typical layout details.) Join the tube sections together and secure with tube couplings as described below: WARNING: THE FOLLOWING COUPLING TIGHTENING INSTRUCTIONS MUST BE FOLLOWED PROPERLY TO AVOID FUTURE PROBLEMS. -
Page 21: Inserting Turbulators
4. Slide the next tube into the coupling. 5. Make sure both tube ends are butted together. 6. Finish tightening both bolts to 40-60 ft.lbs. torque to ensure a complete seal. 7. Use the two Self-drilling screws through the pre-punched holes to secure the tubes in the coupling. 8. -

Page 35: Venting
16.0) VENTING A. BASIC FLUE VENTING — Venting must comply with the latest edition of the National Fuel Gas Code (ANSI Z223.1-latest edition) or the authority having jurisdiction. Other venting references are in the equipment volume of the ASHRAE Handbook. Model Heat Maximum vent length ft. - Page 36 the flue gases, the vent pipe should be insulated and a condensation drain should be provided. 7. Minimum clearance for single-wall flue pipe to combustible material shall be 6 inches. This may be reduced when the combustible material is protected as specified in the National Fuel Gas Code or the authority having jurisdiction.
- Page 37 MULTIPLE HEATER VENTING (CONNECTIONS INTO A COMMON VENT OR MANIFOLD) Requirements for venting of multiple heaters are the same as described for SINGLE HEATER VENTING except as follows: 1. The common vent size and total vent height is normally determined by the number of heaters per common vent, length of horizontal connector runs, and connector rise.
