Element, Enclosure And Cover Length
General
The over-all length of an enclosure or
cover, or of several joined together, is the
same as the ordering length. Over- all
length when an end panel is used is 1
(25 mm) longer than the ordering length.
Over-all length when right and left end
panels are used is 2 (51 mm) longer
than the ordering length.
For wall-to-wall installations, use total
length to the nearest 6 (152 mm)
increment below the actual wall-to-wall
measurement. Enclosure extensions
telescope up to 4 (102 mm) to meet the
wall. Access panels (6 (152 mm) or 12
(305 mm)) and 12 (305 mm) access
panels with 5 x 6 (127 x 152 mm) size
access door centered, provide easy
access to valves and fittings and can be
used for 6 (152 mm) or 12 (305 mm)
runs to the wall.
3
/4 CA (19 mm) copper-aluminum
elements are available in lengths of 1
(.305 m) through 8 (2.4 m ) in 6 (0.15 m)
increments. 1
1
/4 (32 mm) steel or 1 (25
mm) and 1
1
/4 (32 mm) copper-
aluminum elements are available in
lengths of 1 (.305 m) through 12 (3.7 m)
in 6 (0.15 m) increments. Cabinets are
available in lengths of 2 (.61 m) through
8 (2.4 m) in 6 (0.15 m) increments. Type
X covers in lengths of 2 (.61 m) through
8 (2.4 m) in 6 (0.15 m) increments, 24
(610 mm) high cabinets in lengths of 2
(.61 m) through 8 (2.4 m) in 6 (0.15 m)
increments.
Elements
Assume an 18 (5.5 m) of 1
1
/4 (32 mm)
steel, Series 52 element is required for
capacity needed. Unions will be used for
joining sections of the element along
with supply and return connections at
the ends. Two 9 (2.7 m) lengths of
element will be required, with one joint
between them. Total length of the
installed assembly will be: 18 (5.5 m)
(element length) + union joint + lengths
of supply and return connections.
Enclosures
With elements selected to meet capacity
needs, assume enclosures will be
selected to cover elements and piping
connections required. Since enclosures
are available in 6 (0.15 m) increments,
19 (2.7 m) will be used to cover the
above assembly. Two 6
1
/2 (2 m) and one
6 (1.8 m) enclosure, 6 brackets (2 per
enclosure or 1 every three feet (.9m) will
be required. The overall length, including
right and left end panels, is 19 (2.7 m) +
2 (.05 m) = 19 2 (2.75 m).
Wall-To-Wall Installations
To make a wall-to-wall installation with a
total length of 20 4
1
/2 (6.2 m), the
enclosure selection would change. In
addition to 20 (6.1 m) of enclosure, two
5 (127 mm) enclosure extensions
would be required to accommodate the
odd 4
1
/2 (114 mm) dimension. Four 5
(1.5 m) enclosures and eight enclosure
brackets would be needed.
Type X Covers And Type E Covers
Type X or Type E covers are normally
specified to cover only the heating
elements. For an 18 (5.5 m) of element,
three 6 (1.8 m) lengths of Type X or Type
E covers would be necessary. Type X
and Type E covers are supported at the
back and bottom front by wall brackets.
