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 4”
galvanised air duct or with 4” flexible aluminium air duct.
It is recommended that the metallic air ducting material
should be insulated from the air intake up to 5 feet from
the burner to avoid condensation on the outside of the
intake pipe.

CAD-1

Air duct kit consists of 25 feet of insulated

UL/ULC Listed Class 1 air duct, and two 4” steel band
clamps.  The duct incorporates a corrugated flexible
aluminium core, surrounded by fibreglass insulation
covered with a vinyl vapour barrier

.

CAUTION

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 

at

the vacuum relief valve.  

The burner will

need to draw combustion air from the  VRV’s
surroundings if the intake ever becomes
blocked. Therefore non-direct vent installation
codes must be followed.

Comprehensive installation instructions are provided
with the kit.

Outdoor combustion air – side-wall venting, DV-
2000™:

The new DV-2000™ venting system is a sealed system
and completely isolates the furnace from the interior of
the building. The burner is totally unaffected by any
pressure fluctuations within the building which makes it
ideal for tight home constructions.

The DV-2000 ™ venting system requires additional
parts, which are not included with the kit. These
additional parts must be constructed of 3” Schedule 40
PVC, PVC-SWV, SDR-26,SDR-21, Septic Sewer Pipe,
or ABS plastic pipe, fittings and sealant.  Also,
installation procedures, piping and fittings must conform
to the following ANSI /ASTM standards:

PVC

ASTM D-1785

SDR26, SDR21

ASTM D-2241

Septic Sewer Pipe

ASTM D-2729

PVC-DWV

ASTM D-2665

PVC Primer and
Solvent Cement

ASTM D-2564

ABS Pipe and Fittings

ASTM D-2235

Procedure for
Cementing Joints

ASTM D-2855

Additional parts required (not included in VTK kit):

a.  3” elbow fitting as required
b.  3” plastic pipe
c.  3” 90

°

elbow, female-female(for terminal)

d.  3” female to 2” female reducer (Riello 40-BF burner

only)

e.  2” 90

°

elbow, street type, female-male (Riello 40-BF

burner only)

f.  3” female-female PVC or ABS coupling (not sewer

pipe) (Beckett AFII burner only)

g.  transition bushings to go from PVC or ABS to

ASTM D2729 Septic Sewer Pipe (if applicable).

If PVC fittings are mixed with ABS fittings, use a solvent
cement that is approved for bonding the two plastics.

Intake pipe length - DV-2000™:

The DV-2000 ™ venting system has been certified for
120 equivalent feet of 3” intake pipe. Count a 90

°

elbow

as 10 equivalent feet and a 45

°

elbow as 5 equivalent

feet in the calculation.

For Example:

1

5’ Length

= 5 equivalent feet

2

10’ Lengths

= 20 equivalent feet

3

90

°

elbows

= 30 equivalent feet

2

45

°

elbows

= 10 equivalent feet

1

90

°

elbow (terminal) 

= 10 equivalent feet

1

90

°

elbow (Riello Burner) = 10 equivalent feet

Total

= 85 equivalent feet,

which is less than 120 feet,
which is acceptable.

Intake pipe installation - DV-2000™:

Obtain the necessary additional parts, to complete the
installation, and start by piping at the burner. If the
optional vestibule has been installed, remove the
appropriate knockouts in the side panels of the
vestibule. The lower 5” knockout in the right hand panel
is used for the  Beckett AFII burner. The higher 5”
knockouts on the right and left-hand panels are for right
or left connection to the Riello 40-BF burner.

Beckett AFII burner:

Remove the burner intake cover by removing the 3
screws securing it in place. Discard the cover and
screws. Apply silicone liberally around the end of a 3”
coupling and fully insert the silicone end onto the burner
opening. Fasten securely with 3 self-tapping sheet
metal screws.
