CHECK SAFETY SHUTDOWN PERFORMANCE
NOTE:
Read steps 1-7 below before starting safety
shutdown or safety lockout tests for the direct ignition
(DI) module.
1. Turn gas supply off.
2. Set the thermostat or controller above room
temperature to call for heat.
3. Watch for ignition spark immediately or following pre-
purge. See ignition module specifications.
4. Time length of ignition operation. See DI module
specifications.
5. After the module locks out, open gas control and
ensure there is no gas flow to main burner.
6. Set the thermostat below room temperature and wait
one minute.
7. Operate system through one complete cycle to ensure
all controls operate properly.
WARNING
ELECTRICAL SHOCK HAZARD
DANGER OF DEATH OR SEVERE
INJURY.
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.

EDS 6 BURNER ASSEMBLY:
The gas connecting flex should be inspected for any
cracks or breaks. Use a soap solution on the gas flex and
gas piping to verify any leaks.
DO NOT USE OPEN
FLAME FOR LEAK TEST.
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:
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

EDS 6
tube which has
been specifically designed and manufactured for the
Reflect-O-Ray
®
EDS 6
system. Use of substitute
materials can result in an unsafe condition and will void
any and all warranties.
DIAGNOSIS AND TESTING Reflect-O-Ray
®
EDS 6 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 gas 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
airflow switch can be operated with mouth vacuum to
check performance. If airflow switch does not close,
replace airflow switch.
4.
Provided airflow 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. Remove gas jet, inspect for possible obstruction or
incorrect orifice size.
8. Disconnect power and check terminals to be sure that
there are no loose spade connections or broken wires.
