Be sure to inspect the tightness of the stainless steel bands every 4-6 months to minimize small gaps.
If the stainless steel bands become loose, use the 17mm wrench to tighten.
11. Install Right Side Bench Support Panels and Short Bench Back Wood Plank
Start with the right side (side which the heater will be mounted on). You will need to locate
the bench support panel. Please note that the bench support panels are not interchangeable.
Use a Phillips screwdriver (power screwdriver will save time) and the provided screws to
mount the bench support panel to the wood stave next to the acrylic rear panel. See figure
11. Next, locate the short bench back wood plank. Use the leveler to make sure the short
bench back wood plank is level with the bench support panel before using the provided
screws to mount it to the staves. Once installed, the top of the bench support panel should be
flush with the short bench back wood plank. See figure 11a. Now you can locate the other
bench support panel and install it like the first one was installed. See figure 11b.

Attention: The joint position of the stainless steel band should be near
the top and to the inside of the support cradles.
