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.

Horizontal units are not approved for attic installation.
The minimum clearances listed in the preceding table are for fire protection. Clearance for servicing the front of the
furnace and the rear of the lowboy models 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: When power venting a Thermo Pride oil fired furnace with a power venting system other than the system
supplied by Thermo Pride, a fiber chamber and an isolated combustion air kit (PVB or Beckett boot) is to be used
with the other manufacturers power venting system.

All installations and services must be performed by qualified service personnel.

NOTE: On the front flue, lowboy, 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. (See following page
for details)
cCAUTION 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, by following dimensions in Table 1, locate the
center point for the exit of the flue for the particular size furnace. Once the center has been located, use a scribe to
mark the hole size, listed in the chart, which corresponds with the furnace being used. Cut hole out and extend flue
through side casing.
A trim collar may be ordered from Thermo Products to hide the gap around the flue pipe. This trim collar, however,
is not required for operation.
NOTE: ROTATION OF FLUE PIPE IS ONLY ALLOWED FOR LEFT HAND SIDE VENTING
APPLICATIONS.

A. 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, as measured at the 5/16" overfire

All installations and services must be performed by qualified service personnel.

air tap (See Fig. 8). 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.
B. DUCT WORK/AIR CONDITIONING:
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 duct system should again follow the current design standard of Air Conditioning Contractors of America
(ACCA) or ASHRAE Fundamentals volume.
The most common location for the A-shaped coil (A style) is shown in Fig. 2.
Fig 2: Acceptable locations for the air conditioner evaporator coil.
NOTICE: The minimum coil pan clearance for a sectional or drum type heat exchanger is three inches unless
specified otherwise by the individual coil manufacturer.
Fig. 3: An acceptable location for the air conditioner evaporator coil when used with a horizontal furnace.
To obtain proper airflow with an air conditioning coil installed on a direct drive unit the blower motor speed may
need to be changed depending upon the size of the air conditioning system installed and the airflow resistance of the
duct system.
Refer to wiring diagrams for blower motor speed selection tables. Nominal temperature rise range is 55°F to 85°F.

All installations and services must be performed by qualified service personnel.

D. LIMIT POSITION AND LOCATION
cWARNING: The predetermined limit locations on all of the Thermo Pride oil fired furnaces have been tested
and approved by Thermo Products, LLC. in conjunction with Underwriters Laboratories, Inc. Any attempt to
relocate these safety controls or replace these safety controls with a control that is not approved, or is incompatible,
may result in personal injury, substantial property damage or death.
Limit connection for T11 & T16 Front Flue Models
The T11 & T16 Front Flue furnaces only are shipped with two limits installed in the discharge air end of the
furnace. After it has been determined in what direction the furnace will be installed, the correct limit will be
connected to the limit harness.
For the T11 or T16 Front Flue installed with the discharge air to the left (when facing burner, See fig 7A) The limit
at the upper left of the furnace is to be used (T11=350264 160
o

For the T11 or T16 Front Flue installed with the discharge air to the right (when facing burner, see fig 7B ) the limit
at the upper right of the furnace is to be used (T11=350953 120
o
F T16=350953 120
o
F) Attach the harness to the
limit cover from parts bag. Then connect the limit leads to the limit terminals. At this time the cover can be
mounted to cover the limit. The unused limit must now be removed. The opening that is left should be covered
with the provided cover plate found in the parts bag.
Limit connection for T11 & T16 Rear Flue Models
The T11 & T16 Rear Flue furnaces come prewired from the factory. No modifications are needed. See
figures 7C- 7D below for limit locations.
E. BURNER INSTALLATION:
NOTICE: Remove all cardboard packing from around chamber before installing burner.
The oil burner will mount on three stud mounting bolts on the lower mounting plate covering the opening in the
front of the heat exchanger. The end of the burner tube should be inserted no further than 1/4 inch back from the
inside surface of the combustion chamber. A distance further than 1/4 inch back from the inside chamber wall may
cause impingement and sooting.
NOTE: OVERFIRE AIR TAP MAY BE LOCATED ON EITHER SIDE OF FLAME INSPECTION
COVER. (See Fig. 8).

All installations and services must be performed by qualified service personnel.

TWO PIECE MOUNTING PLATE
Fig. 8: Typical location of the overfire air tap
Fig. 9: (Top view) Burner insertion illustration
When mounting the burner, the upper mounting plate (Fig. 8) must be removed to provide access to the area in front
of the combustion chamber. The combustion chamber can then be moved forward or backward slightly to allow for
adjustment in positioning the burner tube. A fiber insulating sleeve or amulet is provided on the burner tube of
specific Thermo Pride burners.(see Fig. 10). See Thermo Pride burner application chart for type of insulator. Do not
allow the burner tube or end cone to physically touch or protrude into the chamber, as excess heat transfer could
result in destruction of the tube, end cone or both. The burner tube/end cone is properly positioned, when the end is
¼ inch back from the inside surface of the combustion chamber wall.
NOTE: The loose-fill insulation that is included in a brown paper bag should be lightly placed around the burner
tube between the front of the combustion chamber and the burner mounting plate. (DO NOT PACK THE
INSULATION DOWN). The loose-fill insulation should be placed in such a fashion that the surface of the
insulation is sloped from the top of the combustion chamber to the top of the lower mounting plate. The purpose of
the loose insulation is to help protect the burner tube, mounting plates and vestibule area from excessive
temperatures.
On the horizontal units, the loose-fill insulation will fall down around the side of the chamber (the chamber is on its
side in horizontal units). This presents no problem to the unit, as the amount of insulation under the side will be
minimal, but take care not to allow the insulation to fall into the open end of the chamber where it may burn and
blow around, possibly lodging in the burner.
NOTE: Do not place loose insulation around chamber sides and back.

* Insulator S = sleeve or N = none
** Maximum nozzle size for UL listing of furnace. The nozzle size gives the nominal flowrate, in GPH, followed by
the spray angle, in degree’s, and the spray pattern, either “H” for hollow cone or “S” for solid cone. For example, a
nozzle rated at 0.65 GPH @ 100 PSIG that provides an 80° spray angle and a hollow spray pattern would be
abbreviated in the table as “0.65 x 80H”. Note: The reason the Riello burner nozzle sizes are smaller than the
standard Thermo Pride Beckett burner nozzles is that pre-set pump pressures are higher, therefore achieving the
same firing rate with a smaller nozzle.
Refer to furnace rating label for heating capacities.

H. HEAT EXCHANGER CLEANING INSTRUCTIONS:
cWARNING: THE HEAT EXCHANGER MUST BE CLEANED BY A QUALIFIED SERVICE
PERSON.
It is important to inspect and clean the heat exchanger once a year, or as necessary, to remove any build-up of soot.
A layer of soot on the inside of the heat exchanger will act as an insulator and reduce heat transfer, resulting in less
efficiency.
To clean the heat exchanger, first turn off all power to the unit. Next, remove the access panel (see below and
beginning of following page) immediately above the burner (on the horizontal furnace, it will be located to the side
of the burner) to gain entry to the clean-out covers, refer to figure 15. This panel is identified with a label. Remove
clean-out covers, the vent connector pipe to the chimney, the burner, and the burner mounting plates. When
removing the clean-out covers, special care must be taken not to damage the gaskets. Should the gaskets separate,
crack, break, or be unsuitable for reuse, the gasket must be replaced before reattaching the clean-out covers.
Fig. 15: Typical Heat Exchanger Cleanout Cover Locations.
With access to the inside of the heat exchanger through the burner area, clean-out openings, and vent pipe
connection, it is possible to use a long, flexible wire brush and an industrial type vacuum cleaner to remove any soot
build-up. NOTE: A one inch (outside diameter) vacuum cleaner hose will fit into the radiator.

All installations and services must be performed by qualified service personnel.
10
To vacuum and brush the outer radiator of the heat exchanger, go through the clean-out openings in both directions,
as shown in figure 16, below.
Fig. 16: Recommended method and device for cleaning inside of heat exchanger.
Reassemble the furnace to its original construction. Remount the burner being certain that the air tube is properly
inserted into the chamber opening (see section E). If heavy soot deposits were found in the heat exchanger, this may
indicate the burner is out of adjustment.

All installations and services must be performed by qualified service personnel.
11
III. USERS INFORMATION SECTION
A. OIL SUPPLY: Do not allow the fuel tank to run completely empty. During the summer, keep the tank full to
prevent condensation of moisture on the inside surface of the tank. If the fuel tank runs completely dry, it may be
necessary to purge the lines of trapped air. Contact a qualified technician to bleed the lines and restart the burner.
OIL SUPPLY VALVE: Turn the oil supply valve off if the burner is shut down for an extended period of time.
B. COMBUSTION AIR SUPPLY: The burner requires a generous amount of clean combustion air to operate
safely. Lack of adequate combustion air can result in erratic operation of the burner, noisy combustion, or fuel odors
in the air. NEVER BLOCK THE FURNACE FROM THE SUPPLY OF COMBUSTION AIR. If there is an exhaust
fan, dryer or return air grill in the furnace room, there should be increased concern and additional efforts may be
required to provide adequate combustion oil to the furnace at all times.
C. INSPECTION AREAS
VESTIBULE: The furnace vestibule area or burner compartment should be inspected by removing the front door
of the furnace and looking for signs of excessive heat such as discoloration of components materials damage, from
rust or corrosion, soot or carbon build-up.
EXTERIOR OF FURNACE: The furnace exterior should be inspected for signs of excessive heat such as
discoloration of materials and damage from rust or corrosion.
FLUE PIPE, VENT PIPE OR CONNECTOR: The furnace vent pipe should be inspected for signs of rust,
corrosion pitting or holes in pipe, and leakage around seams in pipe, indicated by soot or condensate streaks.
CHIMNEY OR VENTING SYSTEM: The furnace venting system should be inspected for signs of rust,
corrosion pitting or holes, and signs of condensation or moisture leakage from the venting system.
If any of the above symptoms are evident, call a qualified heating contractor for assistance.
cCAUTION: DO NOT ATTEMPT TO MAKE REPAIRS YOURSELF!
cWARNING: The area around the furnace should be kept free and clear of combustible
liquids and material, especially papers and rags.
cWARNING: NEVER burn garbage or refuse in your furnace. Never try to ignite oil by
tossing burning papers or other material into your furnace.
cWARNING: Thermo Pride oil furnaces are designed to burn No. 1 or No. 2 distilate fuel
oil. NEVER USE GASOLINE OR A MIXTURE OF OIL AND GASOLINE.
cCAUTION: DO NOT ATTEMPT TO START THE BURNER WHEN:
1. Excess oil has accumulated,
2. The furnace is full of vapors
3. The combustion chamber is very hot.
IF ONE OR MORE OF THESE CONDITIONS EXIST, CONTACT A QUALIFIED
SERVICE PERSON .
D. STARTING THE BURNER:
1. Turn the main service switch to "OFF" position.
2. Set thermostat substantially above room temperature.
3. Open shut-off valves in oil supply line to burner.
4. Turn service switch to furnace "ON". If burner starts and runs, but stops again on lockout, it may be necessary to
bleed the lines or make burner combustion air adjustments. Contact a qualified service person to adjust and start
burner.

All installations and services must be performed by qualified service personnel.
12
E. FILTER CLEANING AND LOCATION:
The air filters should be inspected each month and cleaned when dirty. Cleaning the air filters frequently may reduce
airborne contaminants from entering the furnace and depositing in the furnace, duct system and home.
cWARNING: To avoid injury from moving parts, hot surfaces, or electrical shock, shut
off the power to the furnace before removing any furnace access doors to service the air
filters.
To clean a dirty filter, first remove the blower compartment door at the rear of the furnace, refer to figure 17.
Remove the dirty filter from the filter rack and clean it with a mild soap and water solution. Make sure filter is
thoroughly dry before replacing. Replace the blower compartment door.
