c. Horizontal ducts. Minimum free area of one (1)

square inch per 2,000 Btu per hour input of all

equipment in space. Duct cross-sectional area

shall be same as opening free area.

Alternate method for boiler located within

confined space. Use indoor air if two permanent

openings communicate directly with additional

space(s) of sufficient volume such that combined

volume of all spaces meet criteria for unconfined

space. Size each opening for minimum free area

of one (1) square inch per 1,000 Btu per hour

input of all equipment in spaces, but not less than

100 square inches.

7. Combustion Air/Ventilation Duct Louvers and

Grilles. Equip outside openings with louvers to

prevent entrance of rain and snow, and screens to

prevent entrance of insects and rodents. Louvers and

grilles must be fixed in open position or interlocked

with equipment to open automatically before burner

operation. Screens must not be smaller than ¼ inch

mesh.

Consider the blocking effect of louvers, grilles and

screens when calculating the opening size to provide

the required free area. If free area of louver or grille

is not known, assume wood louvers have 20-25

percent free area and metal louvers and grilles have

60-75 percent free area.

II. Unpack Boiler

CAUTION

Do not drop boiler. Do not bump boiler jacket

against floor.

A.

Move boiler to approximate installed position.

B.

Remove all crate fasteners.

C.

Lift and remove outside container. Save two of the

wooden slats from the container sleeve for use in Steps

E and F.

D.

Remove all boiler hold-down fasteners.

WARNING

Installation of this boiler should be undertaken

only by trained and skilled personnel from a

qualified service agency.

E.

Tilt the boiler to its front side or back side and slide a

wooden slat under the three raised feet.

F.

Tilt the boiler in the opposite direction and slide

another wooden slat under the three raised feet.

G.

Slide the boiler left or right off the skid using the two

wooden slats as runners.

H.

Move boiler to its permanent location.

NOTICE

Boilers operated with direct vent (sealed

combustion) are exempt from needing provisions

for combustion air from the room, provided

air intake piping is installed per Code and the

instructions in the manual.

6. For boiler located within unconfined space in building

of unusually tight construction or within confined

space, provide outdoor air through two permanent

openings which communicate directly or by duct

with the outdoors or spaces (crawl or attic) freely

communicating with the outdoors. Locate one opening

within twelve (12) inches of top of space. Locate

remaining opening within twelve (12) inches of bottom

of space. Minimum dimension of air opening is three

(3) inches. Size each opening per following:

a. Direct communication with outdoors. Minimum

free area of one (1) square inch per 4,000 Btu per

hour input of all equipment in space.

b. Vertical ducts. Minimum free area of one (1)

square inch per 4,000 Btu per hour input of all

equipment in space. Duct cross-sectional area

shall be same as opening free area.

CAUTION

If using indoor air for combustion (see Venting Section - Indoor Air), avoid operating this boiler in an

environment where saw dust, loose insulation fibers, dry wall dust, etc. are present. If boiler is operated

under these conditions, the burner interior and ports must be cleaned and inspected daily to insure proper

operation.
