3. The standard nose burner is supplied with a split-mounting companion flange that can be
bolted onto the dryer breech plate (see Table 4), and is an option for the long nose version.
This allows positioning the burner at various insertion depths past the breech plate. Typical
burner insertion depth is 18 to 24" (460 to 610mm). Cut out a hole in the breech plate 2"
(50mm) in diameter larger than the burner tube. Do not weld the split-mounting flange to the
burner body, as the breech will expand and contract with changes in temperature. If the split-
mounting flange is welded to the burner, heat and stress will damage the burner. Tightly seal
the burner to the breech. If using oil as a primary fuel, the insertion depth may have to extend
more than 24" (610mm) due to the amount of radiant heat from an oil flame depending on the
application.

4. Bolt the burner to the support structure.
5. Wire the main fan motor and the optional TBA blower motor (if applicable) per instructions
on the motor.
6. Rotation of all blowers must be checked prior to burner startup. The rotation is marked with
an arrow on the blower housings. Do not operate the burner until all blowers are
checked for rotation and are rotating correctly.
All rotating components were balanced from factory at a level meeting ISO 1940-2. A variety of
external causes such as handling, installation, or misalignment may cause imbalance prior to
use. To ensure the intended long life of the equipment and components, and to meet warranty
requirements, equipment and vibration levels should be checked by experienced personnel and
trim balanced if no longer meeting ISO 1940-2 requirements. Under no circumstances should
equipment with excessive vibration be operated at the risk of damaging that equipment or the
personnel operating it.
H. FUEL MANIFOLD INSTALLATION
TM
The MegaStar
burner can be supplied with integral fuel manifolds on the burner or with optional
remote rack mounted fuel manifolds. The fuel manifold has all modulating fuel valves mounted on
it. In addition to modulating fuel valves, the manifold includes the automatic oil, gas and LP safety
shutoff valves.
Fuel manifolds must be mounted in a horizontal position. Safety shutoff valves will not function
properly if mounted vertically. Liquid fuel manifolds should not be mounted above the burner
centerline. Oil and LP manifolds should be mounted as close to the burner as possible. For heavy fuel
oil applications, i.e., any fuel requiring heating for use, oil piping must be heat traced (electric or
steam) and insulated. Self-regulating heat tracing is recommended to maintain the desired
temperature of a given fuel oil to achieve 90 SSU (1.8x10
tracing with a nominal rating of 12W/ft (39W/m) covered with a nominal 2" (50mm) fiberglass type
insulation is sufficient for most applications. Fuel oil temperature should not exceed 250°F (120°C).
Oil viscosity should be checked prior to burner operation.
Eclipse recommends the use of schedule 40 iron pipe and fittings rated for 150 psig (10.3 bar) for
natural gas and oil system interconnecting piping. LP applications require the use of schedule 80
pipe and fittings rated for 350 psig (24.1 bar).
