INSTALLATION
Preparation
Most vacuum system designs are laid out on a clean blank sheet of paper. Unfortunately, typical construction does
not permit this unimpeded access and therefore some planning and preparation early in the project will save much
time and effort later.
Start by reviewing the installation procedure. Examine where the equipment will be installed and how it will be
supported. Please pay special attention to any objects that might be in the way or in close proximity to the heating
system. Refer to Table B (Clearance to Combustibles) to ensure a safe distance between the heating system and
any combustible materials.
Acquaint yourself with the standard components referred to in this manual. Many of these components are shown
in detail in Figure 3. They are also shown in general assembly form in Figure 1 and Figure 2 to illustrate where the
components fit in a typical symmetrical system and a non-symmetrical system. (These Figures are found in the
Equipment Specifications section.)
If possible, lay the entire system out on the floor prior to installation. This will help identify any potential problems
with the installation as well as any discrepancy in component quantity. Ensure that all Burners are those specified
for the planned system in both output and gas type.
*DO NOT TRIM/CUT ANY Combustion Tube, adjust the System to fit around the Combustion Tubes.
Layout Limits
Ensure that the System Layout meets the limits required in Table C and Table D.
