Page 21: Typical Suspension Methods
6. Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent structure with adequate load capacity. Space-Ray recommends that the tube sections be suspended using chains with turnbuckles. This will allow slight adjustments after assembly and heater expansion/ contraction during operation. -
Page 22: Assembly Of Tube Sections
10.0) ASSEMBLY OF TUBE SECTIONS During field assembly of the heater tube 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 42: Air For Combustion
If the heater is installed less than 2 ft. from the ceiling, a flexible transition section (e.g., flexible aluminum duct) must be provided to allow for expansion/contraction of straight tube heaters (ETS Series). In colder climates, where necessary, insulate the outside combustion air duct. Avoid locating the outside combustion air duct directly above the control box. - Page 43 In multiple heater applications multiple heater applications, the combustion air intake may be ducted individually or common ducted in the multiple heater applications multiple heater applications same configuration as shown for venting in Section 17.0). For combustion air intake duct sizing, please refer to the Vent Sizing Table Vent Sizing Table and use the diameter indicated, based on the number of heaters per duct.
