General Notes; Draft And Chimney; Oil Tank And Piping - CADDY PF01015 Installation And Operating Instructions Manual

23. GENERAL NOTES

This instruction manual treats mainly of the oil burning unit of your wood/oil combination furnace.
To obtain the maximum efficiency out of your furnace, follow the advice below regarding the installation and
operation of your WOOD/OIL combination furnace.
•
Respect the local codes (when in doubt, consult your local dealer).
•
Respect the clearances indicated on this instructions manual and make sure that they match those
indicated on the appliance's certification label;
•
Make sure that your furnace is installed in conformity with the instructions on the certification label;
•
All the controls adjustments must be performed by a qualified technician.
THE INSTALLATION OF THE WOOD/OIL COMBINATION FURNACE MUST BE DONE IN ACCORDANCE WITH
THE RULES OF THE AUTHORITIES HAVING JURISDICTION AND THE CAN/CSA B-139 M-91 STANDARD FOR
OIL BURNING HEATING APPLIANCES.
OIL BURNING FURNACES ARE NOT APPROVED FOR USE WITH COMBUSTIBLE HEAVIER THAN NO.2 OIL
(FURNACE OIL). DO NOT USE GASOLINE, TRANSMISSION OIL, OR OTHER TYPE OF OIL CONTAINING
GASOLINE.
FOR INSTALLATION IN WOOD/OIL CONFIGURATION, YOU MUST USE OF A 7" CHIMNEY. A 7" TO 6"
REDUCER MUST BE INSTALLED AT THE FLUE OUTLET OF THE FURNACE.

24. DRAFT AND CHIMNEY

The chimney must conform to the rules of the authorities having jurisdiction and the CAN/CSA B139 &
NFPA 31 standard regarding installation of oil burning heating appliances. The installation of the connecting
pipes to the oil unit must be done and approved by a professional.
NOTE: The barometric damper provided with the appliance must be properly installed on
the flue pipe of the oil burning unit. The purpose of the damper is to adjust the draft in the
evacuation pipe of the oil burning unit to the recommended level. Since the evacuation pipe
of the oil burning unit is connected on the evacuation pipe of the wood burning furnace, the
minimum draft to be respected is 0.04 IN.W.C. in the evacuation pipe of the wood burning
side, at all times. In fact, a barometric damper that would be opened too wide could cause
an important loss of draft in the evacuation pipe of the wood burning furnace.

25. OIL TANK AND PIPING

The maximum capacity of the tank must not exceed 200 imperial gallons (900 liters) and the tank must be
located at least 60" from the burner. Local codes will govern the size of the air inlets and filling openings as
well as the type of plugs to be used. 1 1/4" IPS and 2" IPS are usually accepted as minimum dimensions for
the air intake pipes and fill pipes, respectively. The oil line to the burner must be a 3/8" outside diameter
copper tubing for runs up to 50 feet, and ½" outside diameter for longer runs. A manual shut-off valve and
an oil filter shall follow in sequence on the oil line between the oil tank and the burner. The oil line must be
buried or protected adequately to avoid any damage.
