Product Information
J Classic Commercial Finned Tube Radiation JVK-AR11 STJK-II-2
The J Classic Commercial Finned Tube Radiation JVK-AR11 STJK-II-2 is a
heating system designed for commercial use. It consists of a backplate that
needs to be mounted on the wall at the prescribed height. Valve compartments
can also be installed if required. The enclosure can be installed in case of
steam systems (two pipes). The enclosure grille support gussets mount directly
into the ‘V’ bend of backplate, and the bottom of the enclosure is secured
into brackets. Overlapping accessories are installed as indicated on the room
schedule.
Product Usage Instructions
- Mount the backplate (full or partial) to the wall at the prescribed height by referring to the submittal drawing. Ensure that it is straight and level. If valve compartments are being used, make sure that an equivalent amount of backplate is installed.
- In case of Steam Systems (Two Pipe):
- Install the enclosure unless the damper assembly is required. Refer to the damper installation sheet packed with damper blades for installation instructions.
- Start installing the enclosure at the left end of the run, working clockwise. The enclosure grille support gussets mount directly into the ‘V’ bend of backplate. Firmly push the next piece of cover into slip joint tabs of the piece on the left until the run is completed.
- Secure the bottom of the enclosure into brackets and tighten the posi-loc clamps to secure the enclosure.
- Install overlapping accessories as indicated on the room schedule. Valve Compartments are installed similarly to the enclosure. Slip the top back bend between the wall and the backplate and secure the accessory bottom returns to the wall with fasteners.
Note: For more detailed instructions, refer to the installation manual provided with the product.
INSTALLATION INSTRUCTIONS
-
Determine quantities of enclosure and accessories required per wall or run. If installation is wall-to-wall, run backplate to within ½” of adjoining wall(s). If run ends with end cap, extend backplate beyond end of required enclosure 1-1/2″ for 3″ end and 6″ for 8-3/8″ end.
-
Mount backplate (full or partial) to wall at prescribed height (Refer to Submittal Drawing) making sure that it is straight and level. If valve compartments are being used, make sure that an equivalent amount of backplate is installed.
-
A. Hot Water Systems: Water brackets are used to support
the enclosure and a single tier of element. Water brackets do not provide pitch for the element. Install wall mounted hangers alongside water brackets as needed for second tier (row) of element. Install two (2) water brackets per enclosure length up to 6′-0″ of length. Three (3) water brackets per cover 6′-6″ up to 8′-0″of length. Valve compartments should have a minimum of one (1) bracket (Accessories do not require brackets). Insert top of the bracket into ‘V’ bend of backplate (Full or Partial) and insert onto horizontal flange of the Partial backplate. Secure brackets to wall using fasteners (as specified) by others. Supply/Return Pipe hangers (if required) can be mounted to the wall adjacent to the water bracket (every other one). Consult submittal sheet for conditions that will not allow a Supply/Return Pipe Hanger. -
B. Steam Systems (Two Pipe):
Bracket mounted hangers used to support the element(s) are not available for this product. A wall-mounted hanger will be required to support and pitch the element. Install with supply end of element at highest point and pitch down at a rate of ½ inch per 20 foot run. Check length of longest run to insure that the element will not interfere with the top support gusset of enclosure. -
Lay out heating element as required. Place slide cradle onto the bottom of element at each bracket location. The element cradle has two legs that angle out slightly. Position the legs between the fins so there is tension against the legs. This holds the cradle in position. Check submittal drawing for correct position of element fin. For copper tube elements, flush the loop or series with system water after soldering to neutralize the remaining flux material and prevent corrosive action and resulting pinhole leaks.
-
The enclosure can now be installed unless damper assembly is required (see damper installation sheet packed with damper blades). Start enclosure at left end of run, working clockwise. The enclosure grille support gussets mount directly into the ‘V’ bend of backplate. Firmly push next piece of cover into slip joint tabs of piece on left until run is completed. Secure bottom of enclosure into brackets. Tighten the posi-loc clamps to secure the enclosure.
-
Install overlapping accessories as indicated on room schedule. All accessories are overlapping. Valve Compartments are installed the same as enclosure. The top back bend is slipped between the wall and the backplate. The accessory bottom returns to the wall and is secured with fasteners by others.

MAINTENANCE
Before each heating season, remove accessories and enclosure panel to inspect finned tube elements for accumulation of dust or other debris that may accumulate and block airflow between fins. Remove dust and debris from coil fins with a vacuum cleaner or compressed air. Inspect for leaks or areas of corrosion. It should not be required, but if necessary, place a drop of lubricant (machine oil) onto each ball bearing (where applicable) located in the water brackets or bracket mounted hangers. Replace cover and accessories.
