WARNING
Fire or Explosion Hazard.
Can cause property damage,
severe injury, or death.
Carefully follow safety requirements when installing a
burner control.
CAUTION

Control Damage.
Disconnect power supply before beginning installation,
to avoid electrical shock or equipment damage..
IMPORTANT
1. Wiring connections for the relay modules are
unique; refer to Fig. 3-2 or the appropriate
Specifications for individual subbase wiring.
2. Wiring must comply with all applicable codes,
ordinances and regulations.
3. Wiring must comply with NEC Class 1
(Line Voltage) wiring.
4. Loads connected to the DBC2000E must not
exceed those listed on the relay module label or the
Specifications; see Table 3.
5. Limits and interlocks must be rated to
simultaneously carry and break current to the
ignition transformer and fuel valve(s).
6. All external timers must be listed or component
recognized by authorities who have proper
jurisdiction.
7. For on-off gas-fired systems, some authorities
who have jurisdiction prohibit the wiring of any
limit or operating contacts in series between the
flame safeguard control and the main fuel
valve(s).
8. Two UV flame detectors can be connected in
parallel.
9. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and
used in accordance with the instructions, can
cause interference with radio communications. It
has been tested and found to comply with the
limits for a Class B computing device of Part 15 of
FCC rules, which are designed to provide
reasonable protection against such interference
when operated in an industrial or commercial
environment. Operation of this equipment in a
residential area can cause interference, in which
case, the users, at their own expense, may be
required to take whatever measures are required
to correct this interference.
10. This digital apparatus complies with the
requirements as stated in the EN298 standard.
11. Do not install the Burner Controller under any
circumstances in the following locations.
①
Where chemicals or corrosive gases are
present, such as ammonia, sulfur, chlorine,
ethylene compounds, acids, etc.
②
Install the relay module where the relative
humidity never reaches the saturation point.
The relay module is designed to operate in a
maximum 85% relative humidity continuous,
noncondensing, moisture environment.
Condensing moisture can cause a safety
shutdown or damage the device.
③
Where temperatures exceed the maximum
specification for this device.
④
Where excessive continuous vibration exists.
12. Do not bundle power wiring and high voltage
ignition cable with the flame detector wiring, or run
them in parallel within the same conduit. High
voltage cables must be kept separated at least 10
cm from the Burner Controller.
13. Use proper grounding work in accordance with
the engineering standards for electrical equipment
14. Connect the high voltage cable of the ignition
transformer properly to the ignition electrode. A
poor connection can cause an electrical shock or
damage the equipment. Additionally the ignition
transformer must be properly grounded according
the standards.
