350 SERIES RATINGS
SPECIFICATIONS
Cover Assembly
Furnish and install 350 Series model_______
baseboard cover assembly as manufactured by
Slant/Fin Corp., consisting of one-piece, back and
top panel, and one-piece front panel, formed of
cold rolled steel. Bottom and top edges of back
panel shall be formed to provide channels along
entire length, to receive full-height support brackets.
Brackets shall be die-formed of electro galvanized
cold rolled steel, for rigid bracing and spring lock-
ing. Slide-action expansion cradles, formed of
polypropylene, shall be inserted between heating
element and support bracket. Cradles shall protect
element bottom and sides from contact with brack-
ets or cover, confining element to free lateral
expansion for noiseless operation. All cover compo-
nents with a 19-gauge front cover shall be painted
in Nu-White thermosetting polyester enamel and all
cover components with a 16-gauge front cover
shall have a galvanized finish.
Extra-cost Options
Optional damper shall be provided for each length
of enclosure, and shall modulate fully and freely,
yet retain any setting through its arc. Optional 16-
gauge steel with galvanized finish front cover shall
be provided with each length of enclosure. Special
colors available per architect selection or pub. no.
SPC-40.
H-1 Element
Furnish and install H-1 baseboard heating element
as manufactured bySlant/Fin Corp.
consisting of 3/4" nominal copper tubing, with 3" x
3-1/4" x .024" aluminum fins,spaced 48 per linear
foot. The tubing shall not be weakened by expan-
sion in process of manufacture, but shall be forced
through undersized fin holes to obtain a force-fit
mechanical bond. A flange with four teeth shall be
formed on each fin to increase thermal contact
and to space and lockthe fins uniformly in place.
One end of each element tube shall be expanded
to receive the unexpanded end of another, without
couplings.
H-3 Element
Furnish and install H-3 baseboard heating element
as manufactured by Slant/Fin Corp., consisting of
3/4" nominal copper tubing, with 3-5/32" x 2-1/2" x
.011" aluminum fins bent to 2-3/4" x 2-1/2" spaced
55 per linear foot. The tubing shall not be weak-
ened by expansion in process of manufacture, but
shall be forced through undersized fin holes to
obtain a force-fit mechanical bond. A flange with
four teeth shall be formed on each fin to increase
thermal contact and to space and lock the fins uni-
formly in place. One end of each element tube shall
be expanded to receive the unexpanded end of
another, without couplings.
H-4 Element
Furnish and install H-4 baseboard heating element
as manufactured by Slant/Fin Corp., consisting of
1" nominal copper tubing, with 3-15/32" x 2-1/2" x
.011" aluminum fins bent to 3" x 2-1/2" spaced 48
per linear foot. The tubing shall not be weakened by
expansion in process of manufacture, but shall be
forced through undersized fin holes to obtain a
force-fit mechanical bond. A flange with four teeth
shall be formed on each fin to increase thermal
contact and to space and lockthe fins uniformly in
place.One end of each element tube shall be
expanded to receivethe unexpanded end of anoth-
er, without couplings.
H-5X Element
Furnish and install H-5X baseboard heating ele-
ment as manufactured by Slant/Fin Corp., con-
sisting of 1-1/4" nominal copper tubing, with 3" x 3-
1/4" x .020" aluminum fins spaced 48 per linear
foot. The tubing shall not be weakened by expan-
sion in process of manufacture, but shall be forced
through undersized fin holes to obtain a force-fit
mechanical bond. A flange with four teeth shall be
formed on each fin to increase thermal contact
and to space and lock the fins uniformly in place.
One end of each element tube shall be expanded
to receive the unexpanded end of another, without
couplings.
H-6X Element
Furnish and install H-6X baseboard heating ele-
ment as manufactured by Slant/Fin Corp., con-
sisting of 1-1/4" IPS steel pipe (Schedule 40), with
3" x 3-1/4" x 0.028" steel fins, spaced 48 per linear
foot. The pipe shall not be weakened by expansion
in process of manufacture, but shall be forced
through undersized fin holes to obtain a force-fit
mechanical bond. Aflange with four teeth shall be
formed on each fin to increase thermal contact
and to space and lockthe fins uniformly in place.
Both ends of each element pipe shall be expanded
to be threaded with IPS standard threads.
