Professional Service Required

Incorrect installation, adjustment, and use of this burner could result in severe personal injury, death, or substantial property damage from ﬁ re, carbon monoxide poisoning, soot or explosion.

Please read and understand the manual supplied with this equipment. This equipment must be installed, adjusted and put into operation only by a qualiﬁ ed individual or service agency that is:

Licensed or certiﬁ ed to install and provide

technical service to oil heating systems.

Experienced with all applicable codes, standards

and ordinances.

Responsible for the correct installation and

commission of this equipment.

Skilled in the adjustment of oil burners using

combustion test instruments.

The installation must strictly comply with all applicable codes, authorities having jurisdiction and the latest revision of the National Fire Protection Association Standard for the installation of Oilburning Equipment, NFPA 31 (or CSA B139 and B140 in Canada).

Regulation by these authorities take precedence over the general instructions provided in this installation manual.

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 CSAB140 in Canada).

Regulation by these authorities take precedence

over the general instructions provided in this installation 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

1. 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

2. offsets should be removed

Any obstructions such as a protruding joint or a

3. piece of broken tile wedged in the chimney should be removed.

Figure 2 – Chimney Design - Above the Roof

NOTE: Correct chimney design is shown by dotted lines. Incorrect chimney design, as shown by the solid lines, may result in down-drafts.

Section: Inspect/Prepare Installation Site

No other appliance connection should be made to

4. the same ﬂ ue pipe.

The ﬂ ue pipe should have an upward pitch toward

5. the 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, 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.

For those installations not requiring a chimney, such as through-the-wall vented appliances, follow the instructions given by the appliance and power venter (if used) manufacturers.

Combustion Air Supply Information

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.

Appliances located in conﬁ ned spaces

All conﬁ ned spaces should have two (2) permanent openings; one near the top of the enclosure and one near the bottom of the enclosure. Each opening must have a free area of not less than one (1) square inch per 1,000 BTU’s per hour of the total input rating of all appliances within the enclosure. The openings should

NX Burner Manual

have free access to the building interior, which should have adequate inﬁ ltration from the outside.

Exhaust fans and other air-using devices

Size air openings large enough to supply all air-using devices in addition to the minimum size required for combustion air. If there is any possibility of the equipment room developing a negative pressure due to exhaust fans, clothes dryers, etc., either pipe combustion air directly to the burner or provide a sealed enclosure for the burner and supply it with its own combustion air supply.

Direct Air Supply and Side Wall Venting

Connect Outside Air Duct to NX Adapter

Failure to install adapter properly could result in impaired combustion, appliance soot-up, puffback of smoke, and ﬁ re or asphyxiation hazards.

The outside air adapter must be installed by strictly

following the kit installation instructions.

DO NOT attempt to install outside air piping without

using the outside air adapter and instructions provided.

Abundant fresh air is required for proper combustion.

Follow the Outside Air Kit Instructions Exactly

Failure to comply could result in impaired combustion, appliance soot-up, puffback of smoke, and ﬁ re or asphyxiation hazards.

Do not attempt to install outside air piping to

the burner without using the outside air kit and instructions.

For direct vent installations, follow instructions provided with appliance and direct vent system. Outside combustion air is required for direct venting.

When installing an NX outside air adapter (Beckett Part Number 1014U), refer to the instruction sheet supplied with the adapter. This kit allows combustion air to be piped directly to the burner. The NX outside air adapter kit may also be used for chimney vent applications that require outside combustion air.
