ASSEMBLING STACK SECTIONS, TYPE I (SOLID FUEL) AND TYPE II (LIQUID FUEL)
Wear protective gloves and hold the sheet metal securely while curling it
to prevent it from slipping and causing severe cuts.
Prior to the initial use of the H-45 Type I (Solid Fuel) Heater, one section
of the stack pipe assembly must have the flue damper installed. This
procedure is detailed later in this work package.
Before the H-45 can be used for the first time, the individual stack
sections must be assembled. The stack sections are provided as slightly
curved sheet metal sections having seams that must be locked together.
Once locked, they cannot be taken apart. The sections are then
transported in an assembled state with the heater.
To assemble each stack section for first time use, join the formed edges of one of the curved sheets of
metal to form a cylindrical pipe (1). To so this, engage the flat seam section (2) into the crimped seam
section (3) at one end of the section. Fully engage the seam (4) along its entire length.
