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.

Notes: 1 VHF-A** 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 VHF-A** furnaces may be installed on combustible flooring.

NOTE: The VHF-A** furnace is approved for closet installation. If the VHF-A** 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 VHF-A** 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: The manufacturer of this furnace 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: The manufacturer of this furnace recommends the use of a chimney to vent this
residential oil furnace. 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 VHF-A** 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° counterclockwise. Then, remove knock-out in side casing and extend
vent through the opening.

A trim collar may be ordered from the manufacter of this furnace to hide the gap around the flue pipe. This trim
collar, however, is not required for operation. Trim collar/gasket part numbers(s) 14121 / 330073.

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

The VHF-A** may be vented through a standard correctly sized chimney.

The VHF-A** may also be horizontally vented through a side wall. The manufacter of this furnace has available the
Field model FDVS-45/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.

The Field vent kit is set up with 4 inch diameter vent pipe with concentric through-the-wall vent termination/inlet air
vent hood. The combustion air inlet pipe diameter is also 4 inch diameter. For Beckett, the combustion air inlet pipe
will be reduced to 3” diameter with the Beckett side wall vent kit.

The side wall vent may be installed either through the upper knock-out on the left side casing of the unit or vertically
out the top opening of the vestibule. The 4” flexible vent pipe included w/ Field vent kit is able to be installed at 2”
clearance to combustibles.

The combustion air inlet can be installed through the either the lower left side casing knock-out or the lower right
side casing knock-out.

B. DRAFT REGULATORS:

A draft regulator is supplied with the furnace and should be installed according to the regulator manufacturers
recommendations. With the burner operating, use a draft gauge to adjust the regulator to the proper setting. (refer to
the instructions enclosed with draft regulator to adjust to the proper setting). When the burner air supply and draft are
properly adjusted, the overfire draft should be a negative (-).01" to (-).02" WC 1, as measured at the 5/16" overfire
air tap (See Fig. 4). This tap is provided in the upper burner mounting plate. To measure the flue draft, punch a small
hole in the vent connector pipe as close to the furnace as possible and always before the draft regulator.

Note: 1. Draft overfire may be positive for high fire applications but not to exceed (+).02" WC.

C. DUCT WORK/AIR CONDITIONING/SUPPLY/RETURN AIRFLOW AND AIR TEMPERATURE:

If the furnace is used in connection with summer air conditioning (cooling), the furnace should be installed parallel
with or on the upstream side of the evaporator coil to avoid condensation in the furnace heat exchanger. If the
cooling unit is installed with a parallel flow arrangement, dampers or other means used to control flow of air should
be provided to prevent chilled air from entering the furnace. If such a damper is manually operated, it must be
equipped with a means to prevent operation of either unit, unless the damper is in the full heat or cool position.

The supply/return airflow shall be set to obtain an air temperature rise, across the furnace, in the range of 55º to
85ºF. Since the flow resistance of each duct system is slightly different, the airflow (fan speed) may have to be
changed in the field to achieve a satisfactory temperature rise.

One way to measure the temperature rise across the furnace is to insert temperature measuring devices (e.g.
thermometers) into the return air duct and into the supply air duct about 12 inches from the furnace. After the furnace
has been firing continually for over 20 minutes, read the temperature difference between the two (2) thermometers.
The temperature difference should not exceed 85ºF, nor be less than 55ºF. A temperature rise of 70ºF is considered
to be optimum for comfort.

The blower (fan) speed fan is adjusted by changing the fan motor winding energized by the control system. The
furnace is set on fan speed, “ML”, at the factory, refer to page 13 of this manual. To adjust the fan speed, change
corresponding wire from the appropriate fan speed to the “HEAT” tap on the control.
