CF375 Burner Manual

Section: Pre-Installation Checklist

Owner’s Responsibility: Professional Installer/Service Agency

Responsibility:

Follow These Instructions Exactly

Failure to follow these instructions, misuse, or incorrect adjustment of the burner could lead to equipment malfunction and result in asphyxiation, explosion or ﬁ re.

Contact a professional, qualiﬁ ed service agency for the installation, adjustment and service of your oil burning system. Thereafter, have your equipment adjusted and inspected at least annually to ensure reliable operation. This work requires technical training, trade experience, licensing or certiﬁ cation in some states and the proper use of special combustion test instruments.

Please carefully read and comply with the following instructions:

Never store or use gasoline or other ﬂ ammable

liquids or vapors near this burner or appliance.

Never attempt to burn garbage or refuse in this

appliance.

Never attempt to light the burner by throwing burning

material into the appliance.

Never attempt to burn any fuel not speciﬁ ed and

approved for use in this burner.

Never restrict the air inlet openings to the burner or the combustion air ventilation openings in the room.

Follow These Instructions Exactly

Failure to follow these instructions could lead to equipment malfunction and result in asphyxiation, explosion or ﬁ re.

Please read all instructions before proceeding.

Follow all instructions completely.

This equipment must be installed, adjusted

and started by a qualiﬁ ed service agency that is experienced with all applicable codes and ordinances and responsible for the installation and commission of the equipment.

The installation must comply with all local codes and

ordinances having jurisdiction and the latest editions of the NFPA 31 and CSA-B139 & B140 in Canada.

50 Hz motors — The burner

ratings, air settings and nozzle ratings are based on standard 60 hz motors (at 3450 rpm). Derate all ratings 20% when using 50 hz motors. Consult factory for speciﬁ c application data.

High altitude installations —

Accepted industry practice requires no derate of burner capacity up to 2,000 feet above sea level. For altitudes higher than 2,000 feet, derate burner capacity 2% for each 1000 feet above sea level.

Pre-Installation Checklist

Combustion air supply

Adequate Combustion and Ventilation Air Supply Required

Failure to provide adequate air supply could seriously affect the burner performance and result in damage to the equipment, asphyxiation, explosion or ﬁ re hazards.

The burner cannot properly burn the fuel if it is not

supplied with a reliable combustion air source.

Follow the guidelines in the latest editions of the

NFPA 31 and CSA-B139 regarding providing adequate air for combustion and ventilation.

The burner requires combustion air and ventilation air for reliable operation. Assure that the building and/or combustion air openings comply with National Fire Protection Standard for Oil-Burning Equipment, NFPA

31. For appliance/burner units in conﬁ ned spaces, the room must have an air opening near the top of the room plus one near the ﬂ oor, each with a free area at least one square inch per 1,000 Btu/hr input of all fuel burning equipment in the room. For other conditions, refer to NFPA 31 (CSA B1139-M91 in Canada).

If there is a risk of the space being under negative pressure or of exhaust fans or other devices depleting available air for combustion and ventilation, the appliance/burner should be installed in an isolated room provided with outside combustion air.

Clearances

With the burner installed in the appliance, there must be adequate space in front of and on the sides of the burner to allow access and operation. Verify that the clearance dimensions comply with all local codes and with the appliance manufacturer’s recommendations.

Fuel supply Nozzle pressure

Section: Pre-Installation Checklist

Oil Supply Pressure Control Required

Damage to the pump, ﬁ lter or other component seals could cause possible oil leakage and potential ﬁ re hazard.

The oil supply inlet pressure to the fuel unit cannot

exceed 3 psig.

Ensure that a pressure-limiting device is installed in

accordance with the latest edition of the NFPA 31.

The fuel supply piping and tank must provide #1 or #2 fuel oil at pressure or vacuum conditions suitable for the fuel unit (oil pump) on the burner. Refer to fuel unit literature in the literature envelope in the burner carton to verify allowable suction pressure.

If fuel supply is level with or higher than fuel unit —

When the fuel unit is not required to lift the oil, the installation is usually suitable for either a one-pipe or two-pipe oil system. The oil pressure at the inlet of the fuel unit must not exceed 3 psig. Refer to the Mount the Burner Section of this manual for one-pipe or two-pipe fuel supply installation instructions.

If fuel supply is below the fuel unit —

Correct Nozzle and Flow Rate Required

Incorrect nozzles and ﬂ ow rates could result in impaired combustion, underﬁ ring, over-ﬁ ring, sooting, puff-back of hot gases, smoke and potential ﬁ re or asphyxiation hazards.

Use only nozzles having the brand, ﬂ ow rate (gph), spray angle and pattern speciﬁ ed by the appliance manufacturer. Follow the appliance manufacturer’s speciﬁ cations for the required pump outlet pressure for the nozzle, since this affects the ﬂ ow rate.

Nozzle manufacturers calibrate nozzle ﬂ ow rates at

100 psig.

This burner utilizes pressures higher than 100 psig,

so the actual nozzle ﬂ ow rate will be greater than the gph stamped on the nozzle body. (Example: A 2.00 gph nozzle at 140 psig = 2.37 gph.

For typical nozzle ﬂ ow rates at various pressures

see Table 1.

The fuel unit nozzle port pressure is factory set at 140 psig. Some original equipment manufacturer burner applications may call for a lower pressure to obtain a required ﬁ ring rate. Do not change this pressure unless directed to do so by the appliance manufacturer.

Use a two-pipe oil system when the fuel unit must lift the oil more than 8 feet if burner is equipped with a B fuel unit. The return line provided by the two-pipe system is needed to purge the air from the fuel lines and minimize the likelihood of air-related problems during operation.

Inspect Chimney or Direct Vent System

Fire, Smoke & Asphyxiation Hazard

Carefully inspect the chimney or exhaust vent system.

Make sure it is properly sized and in good working

condition.

Follow the instructions supplied by the appliance

manufacturer.

The installation must strictly comply with all applicable

codes, authorities having jurisdiction and the latest revision of the National Fire Protection Association Standard NFPA 31 for the installation of chimneys and vent sizing, (or CSA-B139 and CSA-B140 in Canada).

Regulation by these authorities take precedence over

the general instructions provided in this manual.

Starting with minimum gph ﬁ ring rate, the minimum size recommended is 6” ﬂ ue pipe with 8” X 8” inside chimney, unless speciﬁ ed otherwise by the appliance manufacturer.

A chimney ﬂ ue shall extend at least 3 feet above the highest point at which the chimney comes in contact with the roof, and not less than 2 feet above the highest roof surface or structure within 10 feet horizontally of the chimney. Refer to Figure 2.

Any accumulation of soot or debris in chimney offsets should be removed

Any obstructions such as a protruding joint or a piece of broken tile wedged in the chimney should be removed.

No other appliance connection should be made to the same ﬂ ue pipe.

The ﬂ ue pipe should have an upward pitch toward the

6. chimney of at least 1/4” per foot of length. It should ﬁ t tightly and should not project into the chimney.

Any leakage between tiles, around clean-out doors,

7. or around the vent pipe should be sealed.

INSULATED STAINLESS STEEL CHIMNEY LINERS

The new designs of high efﬁ ciency oil furnaces and boilers in conjunction with ﬂ ame retention oil burners are more efﬁ cient. One result of increased efﬁ ciency is lower ﬂ ue gas temperatures. As ﬂ ue gases rise in the chimney, they will cool and condense when they reach the dew point. The condensation will mix with the sulphur in the ﬂ ue gases creating sulphuric acid. The acid will attack the chimney mortar, brick and clay liners causing corrosion, deterioration and blockage of the chimney. Eventually the blockage could prevent exhausting the ﬂ ue gases. Instead, the ﬂ ue gases could vent out the barometric damper into the living space.

Therefore, it is strongly recommended that an approved insulated stainless steel liner be installed.
