Ducted outdoor combustion air

Three burners are set up to duct outside combustion air
directly to the burner; the Beckett AFII and Riello 40-BF for
side-wall venting and the Beckett AFG for use with
conventional chimney venting. The Riello 40-F is not
suitable for direct-connected outdoor air.
CAUTION
The use of ducted outside combustion air is mandatory
for the side-wall direct venting system. This system
operates on a balanced flue principle and will not
function properly if the combustion air piping is not
attached and sealed at all connections between the vent
terminal and burner inlet.
Outdoor combustion air kit – chimney venting
The following kit has been certified for use on this appliance.
The kit contains an important safety feature, namely a
vacuum relief valve, or VRV. During normal operation the
burner aspirates outdoor air. If the intake terminal ever
becomes partially blocked or fully blocked from ice or snow
etc., the VRV will open to allow a proportion of air from the
dwelling to enter the burner thus maintaining proper
combustion. Once the blockage is removed, the VRV will
close and the burner will draw all air from the outdoors
again.
CAS-2B
Components (except air duct) for the Beckett AFG burner:
The kit includes the intake terminal, vacuum relief valve
(VRV) and special air boot connection with integral air
adjustment means for the AFG burner. The CAS-2B can be
used with a 0.10 m (4") galvanized steel air duct or with a
0.10 m (4") flexible aluminium air duct. It is recommended
that the metallic air ducting material be insulated from the air
intake up to 1.5 m (5') from the burner, to avoid
condensation on the outside of the intake pipe.
The CAS-2B does not turn the furnace installation into a
direct vent system. Therefore, the building structure
must provide for adequate combustion air to be
delivered to the Vacuum Relief Valve. The burner will
need to draw combustion
surroundings if the intake ever becomes blocked.
Therefore, non-direct vent installation codes must be
followed.
CAD-1
This air duct kit consists of 7.6 m (25') of insulated UL/ULC
Listed Class 1 air duct and two 0.10 m (4") steel band
clamps. The duct incorporates a corrugated flexible
aluminium core, surrounded by fibreglass insulation and a
vinyl vapour barrier.
Comprehensive installation instructions are provided with
the kit.

OIL TANKS AND LINES

Check your local codes for the installation of the tank and
accessories.
Prior to each heating season, have the entire oil distribution
system checked for leaks.
A manual shut-off valve and an oil filter shall be installed in
sequence from tank to burner. Be sure that the oil line is
clean before connecting to the burner. The oil line should be
protected to eliminate any possible damage. Installations
having the fuel oil tank below burner level must employ a
two pipe fuel supply system with an appropriate fuel pump;
for more than a 2.4 m (8') rise use a 2-stage pump; for more
than 4.9 m (16') rise an auxiliary pump.
Follow the pump instructions to determine the size of tubing
you need in relation of the lift, or the horizontal distance.

BURNER INSTALLATION

2.7.1

Mounting the burner

The burner mounting plate on the furnace has a 4-bolt
configuration.
1. Check the insertion depth of the burner tube. Refer to
the Technical Specifications, table 3 to 5.
2. Position the mounting gasket between the mounting
flange and the appliance burner mounting plate;
3. Line up the holes in the mounting flange with the studs
on the mounting plate;
4. Securely bolt the burner in place with supply nuts.
2.7.2

After the burner is mounted

1. Remove drawer assembly or air tube combination;
2. Install nozzle (see specifications);
3. Confirm electrode settings;
4. Make the electrical connections;
5. Complete oil line connections.
