3.0 FURNACE INSTALLATION
OIL TANK & PIPING
Tank installation must conform to local requirements.
Install according to the applicable code such as CSA B139 and NFPA 31. Minimize the
number of connections in suction line and make all connections as tight as possible. Use a
pipe joint compound suitable for oil on all pipe threads. To reduce possibility of air leaks,
tighten stem packing gland nut on any valves installed in the suction line. Also, be sure the oil
filter is tight, as filter gaskets often shrink. Check for kinks in the oil lines as well as for
possible air pockets and for loose connections. Two filters as shown below are recommended.
Optional tank gauge protectors and outlet protectors are available at your local dealer.
ONE PIPE SYSTEM
Where the tank is above the burner and when the oil flows by
gravity to the oil pump, a single-stage fuel unit with a single oil line
to the pump may be used.
TWO PIPES SYSTEM
When a single line is unsuitable, use a double line system or see
your dealer for special oil line fittings. Install by-pass plug on burner
fuel unit as specified in the burner manual.
