INSTALLATION NOTES
A. GENERAL INSTALLATION LAYOUT
1. Height from floor - 10' to 30' (refer to chart for
recommended minimum mounting heights). There are
no restrictions on the mounting height of the equipment
providing the design is based on the full heat loss of the
building. Consideration must be given to the building
heat loss so as to cover the air infiltration and/or the
mechanical ventilation of the building. For serviceability
and optimum performance the system should be
mounted with careful consideration to the use of the
building.
B. RADIANT TUBE ELEMENT LENGTHS FOR
STANDARD (OIL FIRED OIL FIRED EDS 3.5)
SYSTEMS.
1. To dissipate maximum heat and avoid continuous
condensation in the radiant tube elements, each burner
will be provided with the minimum or maximum tube
lengths as outlined in the following chart. A heavy walled
16 gauge aluminized steel tube (10' -0") long is used
adjacent or downstream of each burner. The remainder
of the radiant tubing shall be of spiral wound aluminized
steel tube. Each single flow of radiant tube shall
incorporate an adjustable damper for regulating burner
airflow.
2. A multiple burner system consists of two or more
burners. Refer to the following charts for radiant tube
lengths and elbow and tee placement.
C. RADIANT TUBE ELEMENT LENGTHS FOR HIGH
OUTPUT (OIL FIRED OIL FIRED EDS 3.5) SYSTEMS.
1. To dissipate maximum heat and avoid continuous
condensation in the radiant tube elements, each burner
will be provided with the minimum tube lengths as
outlined in the following chart. A heavy walled 16-gauge
aluminized steel tube 10' 0" long is used adjacent to
each burner. The remainder of the radiant tubing shall be
of spiral wound aluminized steel tube. Tee's must be
installed after any turbulator tube. Each single flow of
radiant tube shall incorporate an adjustable damper for
regulating burner airflow. NOTE: The radiant tubes for
the
Reflect-O-Ray
®
OIL FIRED EDS 3.5 systems can
and may be heat treated for optimum heat transfer.
DESIGN TUBE LENGTH REQUIREMENTS
FOR OPTIMUM EFFICIENCIES
The dimensions in the table listed below are basic
guidelines used in the design of the
Reflect-O-Ray
®
Oil Fired
OIL FIRED EDS 3.5 systems. Every effort should be made
to hold the dimensions given on the layout drawing. The
factory should verify any deviations from the layout drawing
or for alternate and/or customized layouts.
