Notice Special Requirements
•
For recommended installation practice in Canada,
refer to the latest version of CSA Standard B139 &
B140.
Concealed damage — If you discover damage to
the burner or controls during unpacking, notify the
carrier at once and fi le the appropriate claim.
When contacting Beckett for service information —
Please record the burner serial number (and have
available when calling or writing). You will fi nd the
serial number on the silver label located on the left
rear of the burner. Refer to Figure 1.
Inspect/Prepare Installation Site
Clearances to Burner and Appliance
•
Provide space around burner and appliance for
ease of service and maintenance. Check the minimum clearances against those shown by the appliance manufacturer and by applicable building
codes.
Inspect Chimney or Direct Vent System
•
WARNING
!
Failure to provide adequate air supply could se-
riously 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.
Adequate Combustion
and Ventilation Air Supply
Required
Inspect the chimney or vent. Make sure it is prop-
erly sized and in good working condition. Follow the
instructions supplied by the appliance manufactur-
Figure 1. Burner label location
er.
Page 4 RWB 6104 BNX R02
Combustion Air Supply Information
!
•
See NFPA Standard 31 for complete details.
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 have free access to the building interior, which should have adequate infi ltration
from the outside.
Inspect/Prepare Installation Site
Fuel Line Installation •
CAUTION
!
Damage to the pump could cause impaired burn-
er operation, oil leakage and appliance soot-up.
Never use Tefl on tape on fuel oil fi ttings.
•
T ape fragments can lodge in fuel line components
•
and fuel unit, damaging the equipment and preventing proper operation.
Use oil-resistant pipe sealant compounds.
•
Do Not Use Tefl on Tape
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/Sidewall Venting Application
•
WARNING
!
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 combus-
•
tion.
For direct vent installations, follow instructions pro-
vided 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.
Route the fuel line through the opening in the bottom
of the burner cover. Continuous lengths of heavy
wall copper tubing are recommended. Always use
fl are fi ttings. Never use compression fi ttings.
Always install fi ttings in accessible locations. To
avoid vibration noise, fuel lines should not run
against the appliance or ceiling joists.
Fuel Line Valves and Filter
•
Install two high quality fusible-handle design shutoff
valves in accessible locations on the oil supply line
to comply with the NFPA31 Standard. Locate one
close to the tank and the other close to the burner,
upstream of the fi lter.
Install a generous capacity fi lter inside the building
between the fuel tank shutoff valve and the burner,
locating both the fi lter and the valve close to the
burner for ease of servicing. Filter should be rated
for 50 microns or less.
NOTICE
To further protect the fuel supply system and re-
duce nozzle orifi ce plugging with fi ring rates below
0.75 gph, a dual fi ltration system can be installed.
This typically consists of a 50 micron primary fi lter,
located near the fuel tank and a secondary fi lter rat-
ed for at least 10 microns located near the burner.
