The

Bryant

Model

246

is

a

low-pressure,

cast-iron

sec¬

tional

boiler

designed

for

use

in

water

or

steam

heating

systems.

The

design

is

certified

by

the

American

Gas

Association

for

use

with

natural

or

propane

gas,

The

type

S

boiler

can

be

used

in

steam

systems

with

a

maximum

working

pressure

of

15

psig.

The

type

W

boiler

can

be

used

in

water

systems

with

a

normal

working

pressure

of

30

psig

and

is

available

for

systems

with

working

pressures

of

50

psig

or

100

psig

when

appropriate

gauge

and

relief

controls

are

used.

All

installations

are

subject

to

codes

established

by

local

utilities

or

other

authorities

having

jurisdiction.

This

jurisdiction

normally

covers

electrical

wiring,

gas

piping,

flue

specification

and

insulation

of

adjacent

combustible

material

where

required

clearances

can¬

not

be

maintained.

As

a

practical

have

been

received.

Also

check

used

,

for

connections,

shall

be

resistant

LOCATING

THE

BOILER

The

boiler

should

be

centrally

located

with

respect

to

the

distribution

system

and

as

close

to

the

chimney

as

possible.

This

boiler

is

not

intended

for

use

on

combustible

.floors,.When

selecting

the

installation

site,

r

emember

.

it

must

have

a

firm,

non

combustible

level

foundation.

Construct

a

level

concrete

pad

if

necessary.

If

the

boiler

base

is

not

level,

the

sections

will

not

align

properly

and

assembly

difficulties

will

be

encoun¬

tered.

If

the

Model

246

is

to

be

used

as

a

steam

boiler

and

is

to

be

connected

to

another

steam

boiler,

the

factory

design

waterlines

of

the

two

boilers

must

be

equal

distance

above

floor

level.
