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:

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)

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, 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

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.

C. HORIZONTAL FURNACE POSITIONS:

The horizontal furnace may be turned end for end, or rotated, making the top into the bottom, as shown in Fig. 11.

After the furnace has been positioned, the bottom burner mounting stud must be broken off before mounting the
burner (See Fig. 12).

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.

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 160oF, T16=350817 150oF) 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 the 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.
