II. GENERAL INSTRUCTIONS - READ BEFORE START OF INSTALLATION

1. The heating output capacity of the furnace proposed for installation should be based on a heat loss calculation
made according to the manuals provided by the Air Conditioning Contractors of America (ACCA) or the American
Society of Heating, Refrigeration and Air Conditioning Engineers, Inc. (ASHRAE).

2. All local codes and/or regulations take precedence over the instructions in this manual and should be followed
accordingly. In the absence of local codes, installation must conform with these instructions and regulations of the
National Fire Protection Association, and to the provisions of the

National Electrical Code (ANSI/NFPA 70-1999 or

latest edition).

3. The installed furnace must be level and positioned in a central location with respect to outlet registers. It should
be located near the chimney to minimize any horizontal run of flue pipe, which may be required.

4. A furnace installed in a residential garage must be installed so the burner and ignition source are located higher
than 18 inches above the floor, unless the required combustion air is taken from the exterior of the garage. Also, the
furnace must be located or protected to avoid physical damage by vehicles.

cWARNING: This furnace is not to be used as a construction heater.

5. Listed below are definitions of "COMBUSTIBLE MATERIAL" and "NON-COMBUSTIBLE MATERIAL."

COMBUSTIBLE MATERIAL:
Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or other material that will ignite
and burn, whether flame resistant or not.

NON-COMBUSTIBLE MATERIAL:

Material that is not capable of being ignited and burned. Such materials consist entirely of, or a combination of,
steel, iron, brick, tile, concrete, slate, or glass.

CSHB60-90 front clearance 6” for Closet, 24” for Alcove.

The minimum clearances listed in the preceding table are for fire protection. Clearance for servicing the front of the
furnace should be at least 24 inches. A clearance of 24 inches is recommended for passage to all points on the
furnace requiring service access.

NOTE: The CSHB60-90 furnaces may be installed on combustible flooring.

NOTE: The CSHB60-90 furnace is approved for closet installation. If the CSHB60-90 is installed in a closet, it

requires two openings in the closet door for combustion air, each having a minimum area of 162 sq. inches. This
free area for the CSHB60-90 intentionally exceeds the recommended minimum free area of 2 square inches per
1000 BTUH of input rate.

Power (Side-Wall) Venting-Important Note Regarding

cCAUTION: Crown Boiler Company will NOT assume responsibility for damage to, and
deterioration of, exterior building materials, e.g. brick, siding, clapboards, and etc., in close
proximity to the vent terminal due to operation of a power vented, oil furnace. This policy
is applicable regardless of the cause of sooting.

Two (2) problems typically arise when power venting any oil-fired appliance.

1) Soot buildup may occur at an accelerated rate on critical components of the

furnace oil burner, e.g. the primary control flame sensor (“cad cell”), the burner
head, oil nozzle, and etc.

2) Severe damage may occur to external surfaces of the structure in the event the

furnace continually produces a high level of smoke in the flue gases. Excess
smoke and soot can be produced for many reasons, some of which cannot be
successfully controlled by the installer and the appliance manufacturer.

NOTICE: Crown Boiler recommends the use of a chimney to vent our residential oil
furnaces. If a power venter must be used, it is the responsibility of the installer and power
venter manufacturer to design and assemble a satisfactory power vent system.

A. VENTING:

NOTE: On the CSHB60-90 it is possible to rotate the flue elbow (which is factory installed for vertical discharge)

90° counterclockwise from the vertical position to adapt to various venting systems.

c CAUTION MUST BE TAKEN NOT TO EXCEED 90° ROTATION (OF THE FLUE

ELBOW) COUNTERCLOCKWISE OR RIGHT FROM THE VERTICAL POSITION.

ROTATION OF FRONT FLUE ELBOW

When an installation requires that the flue exit out the left hand side casing on a front flue unit, remove screw
securing the 90 deg. elbow and rotate it 90°
vent through the opening.

NOTE: ROTATION OF FLUE PIPE IS ONLY ALLOWED FOR LEFT HAND SIDE VENTING
APPLICATIONS.

The CSHB60-90 may be vented through a standard correctly sized chimney.

The CSHB60-90 may also be horizontally vented through a side wall. Crown has available the Field model FDVS­45/FVOP-415 side wall vent kit for such applications. When installing the FDVS-45/FVOP-415 side wall vent kit,
outside combustion air must also be applied to the burner. The following table identifies application order
information.
