Section II 2-1 Location of Heater (continued)
Option 2 illustrates the unit installed on a concrete slab with cut out in the slab for plumbing
and electrical connects to run through. We recommend this pad to be 48” wide by 60”
minimum long. If you add extra length it will allow ample concrete in front of the heater for
loading wood and removing the ashes. The 4” watertight pipe or other means to insulate
plumbing that runs underground exits through this cut out to allow connections to the unit.
The unit sits on the slab with the rear of the water tank flush or even with the front side of
the cutout. The outside cover of the heater can be removed by lifting it from the water tank
on all four corners. This will allow you east access for the plumbing and electrical
connections.
