proper installation. Be sure to locate the unit close enough to a
110 VAC wall receptacle to properly power appliance.
2. When facing the front of the furnace the minimum clearances
from casing to combustible construction are 0" (0 mm) on top,
0" (0 mm) on each side, recommend 4" (102 mm) on sides
for servicing and 0" (0 mm) from the floor, 0" (0 mm) to rear
wall and 40" (1,016 mm) from Mantis top to ceiling.
3. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12" (305 mm).
4. The minimum wall depth is 4" (102 mm) and the maximum
is 48" (121.92 cm).
The vent terminal of a direct vent appliance, with an input of
50,000 BTU (14.6KW) per hour or less shall be located at least

Figure 2
The bottom of the exhaust vent terminal and the air intake shall
be located at least 12" (305 mm) above grade and must be vented
outside.
WARNING: The nearest point of the vent cap should be
a minimum horizontal distant of six (6) feet (1.83 m) from
any pressure regulator. In case of regulator malfunction,
the six (6) feet (1.83 m) distance will reduce the chance of
gas entering the vent cap.
Installation on Rugs and Tile
If this appliance is to be installed directly on carpeting, tile, or other
combustible material, other than wood flooring, the appliance shall
be installed on a metal or wood panel extending the full width and
depth of the appliance.
The base referred to above does not mean the fire-proof base as
used on wood stoves. The protection is primarily for rugs that may
be extremely thick and light-color tile that can discolor.
