COMBUSTION AIR SUPPLY

NOTICE
Air that is not contaminated must be ducted to the
heater if chlorinated or fluorinated contaminants, high
humidity, other contaminants, or if negative pressure is
present in the area where the heater is installed.
The Reflect-O-Ray
®
OIL FIRED EDS 3.5 system is
certified for installation with use of inside air as well as an
outside air supply system. Some compounds such as
halogenated hydrocarbons or other corrosive chemicals in
the air can be drawn into the burner and cause an
accelerated rate of corrosion of various parts of the
system.
If the building has a slight negative pressure or air which
contains contaminants it is strongly recommended that an
outside air supply be used.
It is recommended that a minimum of 48" of straight 4.0"
OD inlet be installed before each burner. Installation of
elbows or "bends" any closer than 48" before each burner
is not recommended. If space will not permit the minimum
48" of straight inlet, install a 4" tee as shown below.
1. The outside air intake consists of: 1 – 4” Inlet hood, 1 -
24" long 4.0" Dia. flex duct and 2 - hose clamps.
2. It is recommended outside air intake assembly be
used. This offsets problems of positive or negative
building pressures, contaminated building air, etc.
Combustion air may be drawn from the space that is
being heated.
3. The 4” duct assembly may extend in length of up to
100 feet by adding minimum 6" diameter sheet metal
duct (P.D. 0.35" W.C. per l00 ft. of duct). A maximum
of 3 elbows may be used.
4. System hanging chains must hang straight down and
chain shall be closed loop type (CM Chain #3, or
equal).
5. If wall is 10" or thicker, add length of appropriate
diameter sheet metal duct.
DO NOT DRAW COMBUSTION AIR FROM ATTIC OR
OTHER SIMILAR CONFINED SPACE.
DO NOT USE "DRYER" TYPE VINYL FLEX.
DO NOT EXCEED 24" OF FLEX.
BROODER &AGRICULTURAL APPLICATIONS
In all brooder and agricultural applications outside air for
combustion must be used.
Secure to wall
and caulk
Whenever possible,
install inlet flex
nearest to wall
