DUCTED COMBUSTION AIR INTAKE APPLICATIONS
The “Ducted combustion air intake kit” (see P.N. 3002762 in the spare parts list - OPTIONAL), allows ducting of exter-
nal air directly into the burner. A 4” diameter air intake is provided in the kit.
The settings of the burner must be according to the BURNER SETUP CHART – AIR INTAKE APPLICATIONS below.
NOZZLES RECCOMANDED:
Monarch R-PLP, Delavan W-B, Danfoss S-B, Steinen SS-S, Hago P.
NOTE:
A 45° degree nozzle is sugg ested, however, a 6 0° degree nozzle may be u sed in cases where the flam e is
unstable at light-off when operated at low ambient temperatures.
NOTES:
A)
This kit is not suitable for direct vent applications.
B)
Always try to minimize the length of the air intake pipe.
C)
Reduce pipe length by 10 feet for every 90° elbow, 5 feet for every 45° elbow.
D)
Reduce pipe length by 6 feet for the 4” to 6” pipe adapter (if used).
E)
Air intake venting should be insulated 10 feet from air intake source with a minimum R7 foil lined insulation, to prevent
condensation or corrosion of air intake venting.
F)
Use an approved type of air intake vacuum breaker and install it in the same room of the burner.
This device should be tested to prove that the vacuum breaker balancer is set correctly and, in the event of intake air
source being blocked, can provide enough combustion air for the burner. If the room where the burner is installed
cannot provide enough air or air quality is a concern, an additional air inlet source must be provided to this room.
G)
On the outside of the wall, use an approved intake air hood, located above the snow line and in such way as to prevent
leaves and/or other debris from blocking the air flow. Refer to local codes for proper location of inlet.
COMBUSTION CHAMBER
Follow the instructions furnished by the boiler/furnace manufacturer. Size retrofit application according to the appropriate
installation codes (eg. CSA B139 or NFPA #31).
To mount this kit on the burner, please follow the installation description given in the kit instruction sheet.
Use a 4” to 6” pipe adapter (not supplied in the kit) to use a 6” diameter pipe.
