INSTALLATION
Installation Sequence
Generally, there is no unique sequence for installation of the burner or heat exchanger. A review of the job site
will usually indicate a logical installation order. However, time and expense can be saved if installation is begun
at the most critical dimension, watching for interference from overhead doors, cranes, auto lifts etc. Figure 5
provides a general overview of the components utilized in the installation, as well as their general relationship.
A general ordered sequence for installation follows for reference.
Note:
Complete assembly by drilling and screwing self-tapping retention zip screws.
