WARNING
ELECTRICAL SHOCK HAZARD
DANGER OF DEATH OR SEVERE
INJURY.
WARNING: ALWAYS DISCONNECT POWER
SUPPLY BEFORE SERVICING THE BLOWER
OR WORKING WITH THE UNIT FOR ANY
REASON. THIS IS ESPECIALLY IMPORTANT
WITH UNITS EQUIPPED WITH AUTOMATIC
THERMAL RESET PROTECTION. UNIT MAY
ACTIVATE WITHOUT WARNING!
GENERAL AND YEARLY MAINTENANCE:
At regular intervals or at least once a year the entire
system should be inspected.

Oil Fired EDS 3.5 BURNER
ASSEMBLY
:
The oil supply system should be inspected for any leaks.
Oil filters and burner oil nozzles must be changed at least
once ever season.
Check combustion air inlets and connecting duct work for
obstructions and breakage; repair as needed.
Inspect hanging hardware, such as chains, for wear. If any
wear is present, the system must not be operated until the
chain(s) or associated hardware has been replaced.
Look for any deterioration in the housing assembly.
Replace or repair.
Radiant Tubing
:
WARNING
FIRE OR EXPLOSION HAZARD
IMPROPER INSTALLATION, ADJUSTMENT,
ALTERATION, SERVICE OR MAINTENANCE
CAN CAUSE DEATH, SEVERE INJURY
AND/OR PROPERTY DAMAGE.
Damaged or nonconforming radiant tubing must be
replaced with appropriate product as manufactured by
Combustion Research Corporation.
The
Radiant Tubing
should be inspected at the beginning
of every heating season. Look for cracks, holes, physical
damage, etc. Replace as needed.
NOTE:
Use only approved
Reflect-O-Ray
®
OIL FIRED EDS 3.5
radiant tube which has been specifically designed and
manufactured for the
Reflect-O-Ray
®
OIL FIRED EDS 3.5
system. Use of substitute materials can result in an
unsafe condition and will void any and all warranties.
DIAGNOSIS AND TESTING
Reflect-O-Ray
®
OIL FIRED EDS 3.5 BURNER ASSEMBLY
:
If the burner does not operate, a "System Check"
must be made as follows:
WARNING
FIRE OR EXPLOSION HAZARD
IMPROPER INSTALLATION, ADJUSTMENT,
ALTERATION, SERVICE OR MAINTENANCE
CAN CAUSE DEATH, SEVERE INJURY
AND/OR PROPERTY DAMAGE.
Perform the safety shutdown test anytime work is done
on a oil system.
SYSTEM CHECK
1. Check for proper installation of unit (refer to owner's
manual).
2. If power is not present, check power supply to input
terminals with AC voltmeter and check fuse in burner
box.
3. Remove tube fitting from air switch and insert new
fitting with short rubber hose attached. Normally open
air flow switch can be operated with mouth vacuum to
check performance. If air flow switch does not close,
replace air flow switch.
4. Provided air flow switch is operating, listen for high
voltage arc, an audible spark "ticking."
(DO NOT
TOUCH IGNITION OUTPUT LEADS OR IGNITION
ELECTRODES.)
Check to see if high voltage leaks
occur at porcelains and high voltage leads.
5. If ignition arc is not present or sporadic, turn off power
and check gap. It should be approximately .10 inch.
(DO NOT TRY TO MEASURE HIGH VOLTAGE
OUTPUT.)
High voltage wire should not touch casing
as grounding can occur when wires are wet.
6. If ignition wires and electrodes are set as above, and
power is shown but no ignition arc is present, the
ignition assembly is defective and the electronics
should be replaced.
7. Inspect oil nozzle for correct size, replace at least
once ever season.
8. Disconnect power and check spade connections or
broken wires.
