1. Drill two 1/8” diameter holes on both sides of wall sleeve
as shown (Figure 1).
NOTE: If there is not enough room to drill holes from the
side then drill holes from inside the wall sleeve.

2. Remove the hydronic kit from its packaging. Recycle the
cardboard packaging material.
3. Mount the two support brackets to the bottom of the
hydronic top (Figure 2) with four (4) 3/8-inch #8 supplied
screws.
On HVK03E Hydronic Steam Kits, do not use 1/4 inch head,
3/8 inch long, #8 screws to attach the left support bracket
to the hydronic top. Use the provided two 5/16 inch painted
head, 1/4 inch long, #8 screws in place of these longer
screws. (Figure 3)
NOTE: Failure to use the 1/4 inch long screws instead
of the 3/8 inch long screws may result in leaks of the
hydronic steam coil.

5. Position the hydronic top with support brackets to the
wall sleeve and fasten the support brackets to the drilled
holes in the wall sleeve with four 1/2-inch #10 supplied
screws. (Figure 5)

6. Place the chassis back into the wall sleeve and secure
chassis to wall sleeve.
7. Measure the actual distance “D” (Figure 6) from the
bottom of the chassis basepan to the finished floor to
determine how far to extend the skirt below the metal
front. If the distance is less than two inches, trim the
skirt per Figure 7 so that it will not interfere with the
gasket or block the inlet air on the front. In Figure 7, “Y”
dimension equals 2” minus actual “D” dimension.
