Installing in small space under the slant fin hot water system

Q: I have problem installing 3/4 x3 hardwood floor. The problem I have is due to the radiant heat slant fin. I cannot nail the starter board under slant fin. If I glue how do I press until glue dries. Need advice. I only have 2 1/4 inches of space under the slant fin hot water system.

A: You will have to have several rows installed out from the rad. Perhaps you can use wedges against the wall to apply pressure to the one row of boards. Or you can gently tap a board between the rad fins and floor board to apply a bit of pressure. Make sure you use a flat, not bowed board. And I would recommend a polyurethane adhesive applied to the floor if able and certainly the underside of the board you are installing.
