DUCTED COMBUSTION AIR INTAKE APPLICATIONS
The "Ducted combustion air intake kit" (see P.N. 3002762 in the spare parts list - OPTIONAL), allows ducting of external
air directly into the burner. A 4" diameter air intake is provided in the kit.
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.
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 suggested, however, a 60° degree nozzle may be used in cases where the flame 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.
