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
®
EDS 6
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 – 6” Inlet hood, 1
– 40” long 6.0” dia. flex duct, 2 - hose clamp
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. It is recommended that a maximum of 3 elbows be
used.
4. System hanging chains must hang straight down and
chain shall be closed loop type (CM Chain #3, or
equal).
4. 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.
