Section 4. Design Requirements
EV-Series systems are typically shipped as burner
packages and tube and accessory packages. The tube
and accessory packages contain enough tube and
reflector and hanging parts for one EV burner. Elbows,
tees, tailpipe, vacuum pumps, controls, and any other
parts must be purchased separately. See Figure 1 below
for a general overview of a simple EV system. Depending
on system requirements, EV systems may be controlled
by either the control panel (shown) or by a relay system.
A number of radiant tube sections are interconnected by
manifold sections to a vacuum pump to form a complete
system. Reflectors can be used over the manifold pipe
but are not required. The system design parameters are
such that the manifold sections are not subjected to
condensate. As a precaution, it is recommended that
aluminized heat-treated or coated tubing is used for the
manifold to increase system life and to handle the initial
condensation during start-up. Damper couplings may be
necessary to balance system vacuum.

EV system. For “mixed” systems: the number
of burners allowed corresponds to the number of burners
allowed for the particular pump and the LARGEST firing
rate being used.
