Theory of Operation of Instant
Electronic Ignition

IMPORTANT: The Non-CE Marked Instant
Electronic Ignition system will attempt to light the
gas by sparking for approximately 15 seconds. If
gas ignition does not take place within
approximately 15 seconds, the Instant Electronic
Ignition control will go into safety lockout and the
valve will no longer open until Instant Electronic
Ignition control is reset. To reset Instant Electronic
Ignition control, remove power from control by
opening and closing the tumbler door. If condition
persists, check that the gas shut-off valve is in “on”
position and that the gas service is properly
connected.

70172201

If condition persists:

1. Check resistance of high tension lead
(approximately 1000 ohms/inch), and replace if
not within resistance range.

2. Check voltage present at valve.

3. Check that machine is properly grounded.

4. Check the gap between igniter and burner tube
(gap should be 1/4-3/8 inch).

5. Check that burner ports are not blocked or
plugged under the igniter.

Safety Information

DANGER indicates the presence of a
hazard that will cause severe personal
injury, death, or substantial property
damage if the danger is ignored.

DANGER

WARNING indicates the presence of a
hazard that can cause severe personal
injury, death, or substantial property
damage if the warning is ignored.

WARNING

CAUTION indicates the presence of a
hazard that will or can cause minor
personal injury or property damage if the
caution is ignored.

CAUTION

Precautionary statements (“DANGER,”
“WARNING,” and “CAUTION”), followed by

specific instructions, are found in this manual and on
machine decals. These precautions are intended for the
personal safety of the operator, user, servicer, and
those maintaining the machine.

IMPORTANT: The word “IMPORTANT” is used
to inform the reader of specific procedures where
minor machine damage will occur if the procedure
is not followed.

NOTE: The word “NOTE” is used to communicate
installation, operation, maintenance or servicing
information that is important but not hazard
related.

WARNING

Failure to install, maintain, and/or operate
this machine according to manufacturer’s
instructions may result in conditions which
can produce serious injury, death and/or
property damage.

W051

NOTE: The WARNINGS and IMPORTANT
instructions appearing in this manual are not
meant to cover all possible conditions and
situations that may occur. It must be understood
that common sense, caution and carefulness are
factors which CANNOT be built into this tumbler.
These factors MUST BE supplied by the person(s)
installing, maintaining or operating the tumbler.

Additional precautionary statements (“IMPORTANT”
and “NOTE”) are followed by specific instructions.

Always contact your dealer, distributor, service agent
or the manufacturer on any problems or conditions you
do not understand.
