FUEL PUMPS
The Model HS oil burner is provided with single stage 3450
RPM fuel pump for a single pipe installation. This is
satisfactory where the fuel supply is on the same level, or
above burner, permitting gravity flow of oil.
A pressure over 3 PSI may cause damage to the shaft
seal and allow it to leak oil.
When it is necessary to lift the oil to the burner, a return line
should be run between fuel pump and oil supply. (If lift
exceeds a height of 10 feet, a two-stage fuel pump must be
used with a return line.) When a two-line installation is
made, a bypass plug must be installed on the Suntec pump.
This is supplied with the burner, attached to the fuel pump,
along with a pump information data sheet in a plastic bag.
FUEL LINES
When oil lines are continuous runs, heavy wall copper
tubing is recommended. Avoid running oil lines overhead,
against the appliance, or across ceiling or floor joists; if
possible, install under the floor. Specific information on
piping, connections, lift capabilities and tank installations is
provided in the instruction sheet of the fuel pump
manufacturer.
Be sure that all connections are completely airtight. Check
all connections and joints. Flared fittings are recommended.
Do not use compression fittings. Avoid using fittings in
inaccessible locations.
Install shutoff valve in oil supply line in accessible locations,
one close to the tank, another close to the oil burner but
ahead of the filter.
Use an oil filter of adequate size on all installations. Install
the filter inside the building between the tank shutoff valve
and the burner.
strainer rating, an external U/L listed filter/strainer must be
placed in the fuel line between the fuel tank and burner fuel
pump.
FUEL TANKS
Local codes and regulations must be followed regarding
tank and burner installation. Check existing tanks for water
and sludge accumulation, clean if necessary. Also clean or
replace existing piping.
AIR SUPPLY FOR COMBUSTION
A burner shall not be installed in an area where facilities for
normal air circulation or infiltration are so limited as to
interfere with ready obtainment of all air necessary for
proper combustion and venting.
Never exceed 3 PSI to the
suction side of the fuel pump.
If the maximum burner firing rate
exceeds the integral fuel pump
When the heating appliance is installed in a confined space,
two permanent openings shall be provided: one near the top
of the enclosure and one near the bottom. Each opening
shall have a free area of not less than one square inch per
1000 BTU per hour (140 square inches per GPH) of the
total input rating of all the appliances in the enclosure.
If the house is of unusually tight construction, has a kitchen
ventilating system, exhaust fans, clothes dryer or vented
fireplaces, it is recommended that combustion air be
supplied through two permanent openings. The openings
shall communicate directly, or by means of ducts, with the
outdoors or to such spaces (attic or craw) that freely
communicate with outdoors. For additional information,
refer to ANSI standard NFPA 31.
CHIMNEY
Follow the recommendations of the appliance manufacturer.
A chimney shall be capable of producing a draft as required
by the appliance and as recommended by the appliance
manufacturer. It must be properly designed, of adequate
size, and should be above the surrounding objects, tile-
lined, with no obstructions, and be in good state of repair.
The smoke pipe should set flush with the inside of tile and
be cemented in place. All cleanout doors should be sealed.
A draft inducer may be used to overcome inadequate draft
conditions. If a draft inducer is used, provisions must be
made to insure the burner does not operate if the draft
inducer fails.
DRAFT REGULATORS
A draft regulator shall be provided unless otherwise
specified by the appliance manufacturer. The draft
regulator shall be installed in accordance with local codes
and regulations or in the absence of local codes, with the
American National Standard NFPA31. Refer to appliance
manufacturer's instructions for recommended over-fire and
stack draft.
