10.0) ASSEMBLY OF TUBE SECTIONS

CUT HAZARD

Sheet metal parts, particularly reflectors and vent have sharp edges. Always use gloves when handling.

Failure to do so may result in death, serious injury or property damage.

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. before hanging heater. Typical suspension methods are shown in Section 9.0.

2.Hang each tube section individually. DO NOT attach the heater tube sections together on the ground and attempt to hang the entire system.

3.In all configurations, the burner box must be connected directly to either a) the 24-hole flange of the 10 ft. aluminized steel starting body section (for 10 ft., 20 ft., and 30 ft. systems) or b) the 6-hole flange of the 10 ft. alumi-therm steel starting body section (for 40 ft., 50 ft., 60 ft., and 70 ft. systems.

4.Assemble a tube support/hanger bracket 4” from the end of the heat exchanger tube having the mounting flange. Align the tube such that the welded seam is facing down toward the ground.

FAILURE TO ASSEMBLE THE TUBE WITH THE SEAM FACING DOWN

WILL VOID THE MANUFACTURER’S WARRANTY.
