Electrical Requirements
a
) Connect wiring as shown in
the wiring diagram which is furnished
inside the electrical control panel box.
b)
Be sure to install a separate
fused disconnect for each. The dis-
connects should be installed in com-
pliance with the NEC (National
Electric Code) and all local codes.
c)
Connections for an optional
audible alarm are provided in the
control panel and are clearly indicat-
ed on the diagram.
Fresh Air Supply for
Boiler
a)
It is most important to provide
free access of air to the boiler. To
burn fuel properly, it requires one
square inch opening of fresh air for
every 3,000 BTU input of fuel.
(6.4cm
2
for every 756 Kcal).
b)
Proper ventilation of the boiler
room is essential for good
combustion.
Install two fresh air
openings,
one at a low level (24”—
610mm from floor) and one at a high-
er level in the boiler room wall.This
will provide a flow of air to exhaust
the hot air from the boiler room.
Room temperature not to exceed
100°F
.
c)
The following openings are
recommended for each size boiler:

Be sure total BHP = proper make
up air opening size. For instance
if you have three 10 BHP boilers,
it is a total BHP of 30, and the 30
BHP make up air opening size is
recommended.
These measurements are subject to
state and local regulations. The
installation of exhaust fans in a boil-
er room is not recommended. An
exhaust fan, or similar equipment
can create down draft in the stack or
restrict the burner’s air supply which
will result In poor combustion. It is
essential that only fresh air is
allowed to enter the combustion air
system. Foreign substances, such
as combustible volatiles and lint, in
the combustion system can create
hazardous conditions.
