E-ITN 40
Manual for installation service and operation M2021/8a EN
7.6. INSTALLATION ON HORIZONTAL AND VERTICAL REGISTERS
7.6.1. Installation description
E-ITN 40 back plate should be installed on the tubular radiators with spacer, welded bolt M3x6 and nut M3,
and two bolt M4x8:
• mark the place for welding bolt on the radiator,
• remove the paint within the diameter of 10 mm on the marked place to see metal surface,
• weld bolt M3x6 onto the register pipes with a one-head welding pistol,
• place the spacer on the bolts tighten to a pipe that front surface is always perpendicularly to the
ground,
• screw the back plate in vertical position to the spacer with two bolts M4,
• place the allocator into the back plate profile groove from top, align it with the base plate and push
allocator to connect it with the back plate.
7.6.2. Proper E-ITN 40 installation on different register types
Horizontal tubes - bare and ribbed:
I. Ribbed tube straight with l ≤ 6 m and bare with l ≤ 12 m
• 1x E-ITN 40 in the centre of the tubular element
II. Ribbed tube straight with l > 6 m and bare with l > 12 m
• 2x E-ITN 40 in the beginning and the end of the tubular element
III. Ribbed or bare tube with one curve
• 1x E-ITN 40 in the beginning of the tubular element arch
• in case of register welded into the frame, place E-ITN 40 on a vertical tube
IV. Ribbed or bare tube with two curves
• 2x E-ITN 40 in the beginning of the upper curve and in the end of the lower curve
• in case of register welded into the frame, place E-ITN 40 on a vertical tube
V. Ribbed or bare tube with more than two curves
• 2x E-ITN 40 always in the beginning of the upper curve and in the end of the lower curve
• in case of register welded into the frame, place E-ITN 40 on a vertical tube
VI. Ribbed or bare tubes connected in parallel
• 2x E-ITN 40 into the middle or approximately to 75% (odd number of tubes) of the height of the
tubular element
Vertical bare tubes:
I. Bare tube with one curve
• 1x E-ITN 40 in the beginning of the tubular element curve
• in case of register welded into the frame, place E-ITN 40 on a horizontal tube
II. Bare tube with two curves
• 2x E-ITN 40 in the beginning of the upper curve and in the end of the lower curve
• in case of register welded into the frame, place E-ITN 40 on a horizontal tube
III. Bare tube with more than two curves
• 2x E-ITN 40 in the beginning of the first curve and in the end of the (last) upper curve
• in case of register welded into the frame, place E-ITN 40 on a horizontal tube
•
• Two or more small tubes connected in parallel
• 1x E-ITN 40 in 75% of the total height and nearest to the centre of tubular element
