the ground. We put a large full-size door on the back that will allow you easy access for
the connection of the plumbing and electrical lines.
We recommend the pad to be 48” wide and 82” long, minimum. If you add extra length,
it will allow ample concrete in front of the furnace to stand, for loading wood and
removing ashes. Larger models than the 165 need to have a longer pad.
Shaver Pro Series 140 - 48" x 114" Suggested pad size
Shaver Pro Series 165* - 48" x 120"
Suggested pad size
Shaver Pro Series 250 - 48" x 136" Suggested pad size
Shaver Pro Series 290 - 48" x 144" Suggested pad size
Shaver Pro Series 340 - 48" x 154" Suggested pad size
The PVC pipe is always buried below the frost line and
most jurisdictions require a
18-24” minimum depth for the electrical wire, sometimes separated from Pex by 18”.
See the illustration below for the recommended pad size and pipe placement for a 165
furnace. Other suggested pad sizes shown above.
