5.0 REGULAR MAINTENANCE & CLEANING
Check complete operation at least once a year. Heat exchanger can be accessed for
cleaning through the breech cleanout cover and burner opening. Clean flue pipes on a
regular basis. Replace flue pipes if there is any sign of corrosion or other problem.
Cerafelt (1/4”) gaskets may have to be replaced on cleanout cover.
6.0 OIL TANKS & PIPING
Tank installation must conform to local requirements.
Install according to the applicable code. Minimize 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. Further
information is available at www.kerrheating.com.
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 PIPE SYSTEM When single line is unsuitable, use double line or see your
KERR dealer for special oil line fittings.
See your KERR dealer for information on tank systems.
