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

 

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. 
 

c

CAUTION: DO NOT ATTEMPT TO MAKE REPAIRS YOURSELF! 

 

c

WARNING: The area around the furnace should be kept free and clear of combustible 

liquids and material, especially papers and rags. 

 

c

WARNING: NEVER burn garbage or refuse in your furnace. Never try to ignite oil by 

tossing burning papers or other material into your furnace. 

 

c

WARNING: 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. 

 

c

CAUTION: 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.
