Oil Heating At Its Best
ermo Pride —
Dependable Craftmanship
For over 60 years, Thermo
Pride has listened to your
concerns about comfort
and has met your demands
for the best, most reliable,
and effi cient furnaces and
cooling systems. Every
Thermo Pride product
is built with traditional, dependable craftsmanship.
What this means to you is quiet, reliable, long lasting
performance.
Comfort
Comfort is the purpose behind any heating system.
“Temperature rise” makes the difference between
feeling warm, comfortable air from the registers in
your home or the feeling of cool air blowing across
you when the furnace is on. It is the difference
in air temperature from the point where it enters
the furnace to the point where it exits. The higher
the temperature rise—the warmer the air when it
enters the rooms of your home. Thermo Pride has
a standard 70°F temperature rise across its full line
of oil furnaces. This is an air temperature up to
30°F warmer than the competition—providing a far
superior comfort level.
insulated furniture grade steel cabinet helps retain
heat within the furnace and prevents annoying
vibrations during operation. The rounded corners add
structural strength and a pleasing appearance to the
cabinet.
The heat exchanger is fabricated of 13-gauge
copper coated steel in a unique octagonal shape to
increase the surface area and the heat transfer of the
heat exchanger. The copper coating helps prevent
corrosion from external damp conditions. This
unique combination of design and material provides
Thermo Pride oil furnace owners with the confi dence
that these furnaces are made to last a lifetime!
Warranty
The proven longevity of Thermo Pride’s heat
exchanger, combined with the Limited Lifetime
Warranty, virtually eliminates the worry of ever
having to replace your furnace. Should you sell your
home, the heat exchanger warranty will automatically
transfer to the new owners. Thermo Pride furnaces
also come with a “Peace
of Mind” 10-year parts
warranty.
Several of our oil furnaces bear the ENERGY STAR®
logo. These products are 85% or more effi cient, with
an energy effi cient blower system saving you money
on energy bills.
Temperature Rise
Handcrafted Quality
Each Thermo Pride cabinet is powder coated inside
and out for a durable, tough fi nish that will ensure
long life and a quality appearance. The interlocking
Thermo Pride’s manufacturing facilities have earned
the prestigious ISO 9001:2000
certifi cation. This seal assures
consistent quality products through
a structured quality control process
Thermo Pride oil products have also

Premiere Oil Furnace with ECM
Blower System
Dependable Craftsmanship with Maximum Comfort
When you want to experience exceptional comfort, increased effi ciency, and
quieter operation while still receiving the handcrafted quality and proven
warranty of Thermo Pride’s traditional oil furnace, select the Premiere Oil
Furnace with the ECM variable-speed blower motor. Since the ECM motor
automatically adjusts its speed for varying heating and cooling modes your
home’s maximum comfort is achieved.
Some of the ECM benefi ts include:
• Energy bills will be lower due to increased electrical effi ciency of the ECM
Motor (especially when you run the blower for long periods of time.)
•
Quieter start up, greater effi ciency, and more comfortable operation due to infi nite fan motor speeds
• Delivery of comfortable airfl ow in both the heating and cooling modes. On a call for heat or cooling the
blower motor starts at the slower speed and builds to the correct running speed
• Automatically compensates for restricted ducts or a dirty air fi lter by increasing the motor speed
(routine fi lter cleaning is still recommended.)
• Reduced fan speeds will save energy and increase comfort levels when the blower runs in circulation mode.
Saving to Experience
Since the ECM variable-speed blower motor uses less electricity than a conventional blower motor, not only will
you have increased comfort, but you can also save money (based on 0.08/kWh electric cost). Savings will vary
depending on model and motor size.
1. Annual Savings for heating your house — average $58
2. Annual Saving for heating and cooling your house — average $76
3. When using a constant fan that runs for air fi ltration, your annual savings can average $480 for just heating
your house or $429 for heating and cooling your house.
“This Furnace is much quieter. Heats rooms that were cool with previous furnace.
So far we have used less kw of power each month compared to the previous year.”
Bob Williams, VP of Rossoe Energy Systems & Oil Company

Home in Mind
Cabinet Construction
Thermo Pride cabinet panels are fabricated of 22gauge cold-rolled steel with rounded corners and
an interlocking design for a
more fi nished appearance
and greater strength. The
cabinet is powder coated
on both sides and is lined
with ½” thick reinforced
fi berglass insulation for maximum heat retention.
On all basement, upfl ow and horizontal furnaces,
Thermo Pride incorporates a burner vestibule
enclosure into its design. The vestibule and insulation diminish burner combustion noise and
provide safety by isolating controls from children
and pets.
The octatherm heat exchanger’s unique eight sided
design provides more effi cient use of the heat trans-
fer area. This design puts less stress on the steel and
thus provides a longer life. As a result, the octatherm
design generates increased dependability and a life-
time of comfort for your home.
Perfect Application
Thermo Pride oil furnaces provide complete product
fl exibility. Available in BTU per hour output rages
from 85,000 to 320,000 to comfortably heat any size
home, Thermo Pride oil furnaces offer the widest
selection available—there’s one that’s right for your
home.
Octatherm™ Heat Exchanger
At the heart of every Thermo Pride oil-fi red
furnace is the “Octatherm” heat exchanger. The
heat exchanger is fabricated out of 13-gauge
copper coated steel. Some
manufacturers use less
expensive, thinner 14 or
16-gauge steel. Thermo
Pride’s copper powder
coating helps prevent corrosion from damp conditions often encountered
in basement installations.
Thermo Pride further stands out by individually
sizing its heat exchangers for virtually every model
furnace offered. This helps to assure maximum
effi ciency, longest life, and the highest comfort for
all applications.
Choose from two different confi gurations.
1. Lowboys (OL) for basement use, or where
height may be limited, feature a vestibule-
enclosed burner and either rear or front fl ues.
2. Horizontal (OT) models are designed for crawl
spaces, and are available with either front or
rear fl ue. They are can be installed with either a
right or left hand discharge.
