A typical layout for RDB burner intake air
A
Use an approved air intake kit.
B
Always keep intake air run to the minimum.
C
Maximum intake air run of 4 (inch) diameter, flexible or rigid
type of venting = 100ft.
D
Reduce intake air length by 10’ for every 90° elbow used. 5’
for every 45° elbow used.
E
It is suggested that air intake venting be insulated with R7
(min.) foil lined insu lation a minimum of 10’ from air intake
source (prevent condensation or corrosion of intake air vent-
ing).
F
Used approved type of intake air vacuum breaker and to be
installed in the same room and the burner, for the event of
intake air source being blocked, this device should be tested
to prove that in the event of intake air source is blocked that
the vacuum breaker balancer is set correctly and can provide
sufficient air for combustion for the burner.
If the room that the burner is installed into cannot provide
enough air or air quality is a concern, an additional air inlet
source will have to be providing to this room.
