provide

air for combustion

and

for operation of

the

barometric

draft control.

For installation

enclosed utility

room

with

outside wall, a

fresh air opening

to the outside

should be made

with a free cross

sectional area

of twice the area

of the

flue outlet. For

each

1,000 feet above

sea level,

increase fresh air

opening by at

least

four

percent.

Isolate the

room from any area served

by exhaust

fans.

Chimneys

must be

properly

designed,

adequately

sized,

terminated

above surrounding

objects,

unobstructed and be

in a

good

state

repair. All cleanout

openings should

sealed.

Refer to boiler

manual

lor details.

A draft regulator

is furnished and

should be mounted

in the smoke

pipe

18 to 20

inches from collar between

boiler and chimney.

Use a

draft

gauge

to adjust

proper

opening.

When burner air

supply and dralt

properly

adjusted, combustion

chamber draft

will be approximately

0.01

to 0.02"

W.C. The larger the

installation, the

greater

the

draft

a. Swing

open transformer.

b. Remove nozzle

bubbles. Close bleed valve.

Burner

ignite.

10. Make final adjustments with COMBUSTION

TEST EQUIP-

MENT.

Allow

l0 minutes

for warm-up:

Check

smoke

(it

should

be zero

on Bacarach scale).

2. Check draft

(.0l"

to .02"

W.C.

in combustion chamber).

3. Check

percent

of COz

(should

be between ll and

l3%d.

To increase

percent

of CO:, lower combustion air band

setting.

To decrease

percent

of COr,

increase combustion air band setting.

4. Start and stop unit

several times.

5. Check

operation of

limits, thermostats and safety

timing

com-

bustion control.

6. Check

for oil leaks.

ALL INSPECTIONS

SHOULD

BE RECHECKED

AFTER
