Bryant GAS-FIRED 454 - Manual (Page 3)

Mounting Base
The unit is supported on 3 rails attached to
the bottom of the base. These rails extend
the full width of jiie unit as shown in the
dimensional drawing on page 2 .
The recommended types of mounting bases
for all installations are:
a . Precast concrete lintels .
Use three lintels run the depth of the unit;
one each under the right and left end and one
at the center of the unit.
b, Concrete blocks .
Use a block under each corner plus a block
under each of the two long sides midway be­
tween the corner blocks . Arrange the blocks
so that the center rail as well as the front
and back rail is supported.
c . Concrete slab.
Minimum thickness 4 inches.
CAUTION: ALWAYS USE NON-COMBUSTIBLE
MATERIAL FOR THE BASE.
)
Clearances
The condenser coil is located at the front of
the unit with the condenser air inlet through
the rear fan opening and the discharge
through the louvered front panel.
The minimum clearance between the back of
the unit and a wall is 15 inches. If the over­
hang is less than 7 feet above the unit, the
unit must be mounted outside a plumb line
from the eaves of the overhang. The clear­
ance on the right and left ends should be a
minimum of 2 feet to provide access for
servicing.

* Note:
Values shown in the above table are for one direction only, and using Bryant water coils. Total length of pipe,
from chiller to coil and return, would be double the values shown. Values apply to single unit installations only.
All distances shown are calculated
on the
predication that only long elbows are used. Galvanized well head elbows
are used with the polyethylene pipe. When using plastic hose, avoid any sharp bends that would tend to restrict or
stop the flow of water.
