Instruction Manual
Installer/servicer — Except where specifically
stated otherwise, this manual must be used
only by a qualified service technician. Failure
to comply with this or other requirements in this
manual could result in severe personal injury,
death or substantial property damage.
User — The burner Instruction Manual is in-
tended only for your service technician. The
burner and heat exchanger must be inspected
and started at least annually by your service
technician.
The National Oilheat Research Alliance (NORA)
recommends single pipe oil systems and high-
quality filtration for all fuel types. This should in-
clude at least a 10 micron Spin-on filter. Double
filtration provides even greater assurance clean
fuel will get to the pump. Contaminants in the
tank that enter the fuel supply to the burner
can cause pump sticking/seizing. These con-
taminants may increase in the early stages of
transitioning to modern fuels (Ultra Low Sulfur
and Bio Blends). High quality filtration adds
protection against pump sticking.
