7. For "D"(-OBD-XXX, -OPD-XXX and etc.) series oil furnaces, Replace the junction box / primary control to the wall of the

furnace in the same fashion as the original factory placement. Replace the furnace door.

For "F"(-OBF-XXX, -OPF-XXX and etc.) series oil furnaces, Replace the primary control to the junction box and replace the
junction box cover on the junction box on the wall of the furnace in the same fashion as the original factory wiring. Replace the
furnace door.

8. Return the system to normal operation by installing the furnace doors and applying power to the system. System operation

should be verified as described in the next section.

SEQUENCE OF OPERATIONS WITH SS1R POWER SIDEWALL VENTER INSTALLED ON RHEEM, RUUD,
OR WEATHERKING OIL-FIRED FURNACES.

When the thermostat calls for heat, the Honeywell burner control is closed. This causes 115 VAC to be applied to terminal #1 of
the SS1R terminal strip of the UC1 control board. The #1 contact on the terminal strip supplies 115 VAC to the "M" and "MTR"
spade connections on the SS1R control board causing the Beckett burner and the induced draft motor to start immediately upon a
thermostat heat-call. At this point, the burner is running, but the oil valve is still off, so combustion has not yet started. When the
induced draft motor gets enough speed to close the pressure switch, the switch contacts operate a relay on the control board
which then supplies power to the oil solenoid valve. At this point, combustion should take place.

Once the thermostat is satisfied, the Honeywell burner control will remove 115 VAC power from terminal #1 of the SS1R UC1 con-
trol board. As a result, the oil solenoid valve snaps closed immediately and this action causes the burner flame to extinguish
immediately. The loss of power to terminal #1 of the SS1R control board begins the post-purge period. The "M" and "MTR" termi-
nals on the SS1R control board will remain energized with 115 VAC for the entire post-purge period. This means that both the
Beckett burner and the Induced draft motor of the SS1R will remain powered for the user-selected post purge period (although no
flame is present). No flame will be present during the post-purge period because the oil solenoid (which was turned off immedi-
ately when the heat-call ended) will prevent the oil from flowing.

SELECTION OF PRESSURE SWITCH BLEED ORIFICE

In order for the SS1R pressure switch to function properly for the intended application, the proper bleed orifice has to be selected
as determined below.

1. Upon installation, if the furnace input rate is 1

gallon per hour or less (140,000 BTU/hr. or less),

then the plug should be installed in the pressure

switch.

2. Upon installation, if the furnace input rate is

greater than 1 gallon per hour or 140,000 BTU/hr.,

then the #33 bleed orifice should be used.

3. Once the proper bleed orifice has been determined,

install into bleed orifice port as shown in Diagram S.

DRAFT ADJUSTMENT OIL

The SS1R Vent system will properly vent a wide range of BTU/hr. input capacities. To compensate for different burner capacities,
vent connector lengths and wind conditions it features a draft adjustment located on the outside of the Vent Hood. In general,
positioning the draft adjustment inward will cause the SS1R to operate at lowest capacity. Positioning the draft adjustment
outward will cause the SS1R to operate at highest capacity.

IMPORTANT:
The following paragraph describes the initial draft adjustment. It may be necessary to make a slight readjustment to compensate
for various conditions: wind, vent connector resistance, negative building pressure and multiple appliances.

ASHRAE lists the average design factor for wind loads in North America at 15 MPH. Refer to the Draft Adjustment Chart on page
15. We recommend that the 25 MPH category be used to allow for excursions beyond the 15 MPH average. It is not recom-
mended for the SS1R to be terminated on a wall that faces the direction of the prevailing winds. Backdrafts by severe winds can
cause oil odors to remain in the structure and/or interrupt heating equipment operation. If the SS1R is terminated in a direction
prone to higher winds, or if higher winds are common in your geographic area, use the 40 MPH category to determine the proper
draft adjustment setting. If the draft adjustment is set at the 25 MPH category and sustained winds exceeding 25 MPH are pre-
sent, the Fan Proving Switch will act to close the oil solenoid valve. Wind loads referenced are based on straight line winds
directed against the Vent Hood.

DRAFT ADJUSTMENT PROCEDURE:

1) Set the draft adjustment to the appropriate setting based on the above instructions and the Draft Adjustment Chart. Adjustment

is accomplished by loosening both nuts on each side of the Vent Hood and centering both indicators to the desired setting.
Tighten the four nuts to secure the draft adjustment at desired setting.
