Outdoor combustion air kits – 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 101.6 mm (4") 
galvanized steel air duct or with a 101.6 mm (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.  

 
 

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 

to 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. 

 
 

CAD-1

 

This air duct kit consists of 7.6 m (25') of insulated UL/ULC 

Listed Class 1 air duct and two 101.6 mm (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. 

 

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 construction. 

 

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 inch 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 solvent cement that is 
approved for bonding the two plastics. 

 

Intake pipe length - DV-2000™ 

 

The DV-2000 ™ venting system has been certified for 37 equivalent m 
(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 m (5') length        = 1.5 equivalent m   (5 equiv. feet) 

3.0 m (10') lengths    = 6.0 equivalent m (20 equiv. feet) 

3 90

°

 elbows                = 9.0 equivalent m (30 equiv. feet) 

2 45

°

 elbows                = 3.0 equivalent m (10 equiv. feet) 

1 90

°

 elbow (terminal) = 3.0 equivalent m (10 equiv. feet) 

1 90

°

 elbow (Burner)   = 3.0 equivalent m (10 equiv. feet) 

 

Total      = 25.5 equivalent m (85 equivalent feet);  

this is below the 37 equivalent meters (120 equiv. feet). 

 

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 127.0 mm (5") knockout in the right-hand panel is 
used for the Beckett AFII burner. The higher 127.0 mm (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 siliconed end into the 
burner opening. Fasten securely with 3 self-tapping sheet metal 
screws. 

 

Riello 40-BF burner 

 

Fully insert the female end of the 2" 90

°

 street elbow into the 

combustion air fitting on top of the burner. Fasten securely with 3 self-
tapping sheet metal screws. Cement the 2" end of the 3" female to the 
2" female reducer onto the male end of the 2" 90

°

 street elbow. If 

these parts are not easily obtained, use a 3" 90

°

 street elbow with the 

male end fitted over the combustion air fitting. The fitting will have to 
be silicone sealed as the fit is a bit loose. Fasten securely with 3 self-
tapping sheet metal screws.  

 

Terminal connection 

 

Insert the 3" 90

°

 female-female elbow onto the stainless steel air 

intake fitting located on the right side of the vent terminal (viewed from 
the rear). Fasten securely with 3 self-tapping sheet metal screws.  

 

Intermediate piping 

 

Pipe as required between the terminal and the burner. Ensure that the 
3" piping is routed and supported in accordance with local and 
national codes. Obey minimum furnace clearances to combustibles 
when routing any section of 3" piping in the vicinity of the furnace. If 
Septic Sewer Pipe is to be used, install transition bushings on the 3" 
female ends of the fittings at the burner and at the terminal. Transition 
bushings are readily available and are required because 3" PVC and 
ABS pipes have a typical outside diameter of 3.5", whereas Septic 
Sewer Pipe has a typical outside diameter of 3.25".  

 

1.6) 

OIL TANKS AND LINES 

 

Check your local codes for the installation of the tank and accessories. 

 

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 a 4.9 m (16') rise, an auxiliary pump.
