PREPARATION

 

 

 

The

 

unit

 

was

 

test

 

operated

 

and

 

inspected

 

at

 

the

 

factory

 

prior

 

to

 

crating

 

and

 

was

 

in

 

proper

 

operating

 

condition.

 

If

 

the

 

heater

 

has

 

incurred

 

damage

 

in

 

shipment,

 

document

 

the

 

damage

 

with

 

the

 

transport

 

company

 

and

 

contact

 

your

 

supplier.

 

Before

 

installation

 

check

 

that

 

the

 

appliance

 

as

 

described

 

on

 

the

 

packaging

 

label

 

is

 

in

 

accordance

 

with

 

the

 

correct

 

type

 

and

 

model

 

as

 

specified

 

on

 

the

 

data

 

plate

 

and

 

complies

 

with

order.

 

After

 

unpacking

 

the

 

appliance,

 

leave

 

it

 

fastened

 

to

 

any

 

base

 

packing

 

for

 

transportation

 

until

 

it

 

has

 

been

 

suspended

 

or

 

until

 

just

 

before

 

base

 

mounting.

 

This

 

affords

 

protection

 

to

 

the

 

underside.

 

 

Check

 

the

 

rating

 

plate

 

to

 

determine

 

if

 

the

 

heater

 

is

 

appropriate

 

for

 

the

 

intended

 

installation.

 

 

Read

 

the

 

manual

 

thoroughly

 

and

 

become

 

familiar

 

with

 

the

 

installation

 

requirements

 

of

 

your

 

heater.

 

If

 

you

 

do

 

not

 

have

 

knowledge

 

of

 

local

 

requirements,

 

check

 

with

 

the

 

gas

 

supplier

 

and

 

any

 

other

 

local

 

agencies

 

that

 

might

 

have

 

requirements

 

concerning

 

this

 

installation.

 

 

Before

 

beginning

 

make

 

preparations

 

for

 

necessary

 

supplies,

 

tools

 

and

 

manpower.

 

If

 

the

 

installation

 

includes

 

optional

 

parts,

 

install

 

these

 

options

 

before

 

the

 

heater

 

is

 

suspended.

 

Follow

 

the

 

instructions

 

included

 

in

 

the

 

option

 

package.
