European Directives
Gas Appliances Regulation: 2016/426/EU GAR
Low Voltage Directive: 2014/35/EU LVD.
EMC Directive: 2014/30/EU EMC (Immunity Emission
conformity can only be verified in combination with

GASTEC: certificate # 18GR0996/00, PIN 0063CT1466
Applicable Standards:
EN 298:2012 Automatic burner controls
EN 60335-2-102 Household and similar electrical
appliances
EN 746-2 Industrial thermo-processing - fuel handling
systems
IMPORTANT
To comply with EN60730 for remote mounting of
the display and/or remote reset, provide electrical
separation using insulation at least equivalent to
double or use reinforced insulation. Accomplish
this by optically isolating the communication
and/or remote reset lines from the control cabinet,
or providing physical separation from the commu-
nication and/or remote reset lines using electrical
conduit and part number 204718A Remote Dis-
play Cover Assembly or other suitable enclosure
that meets NEMA4 class of protection.
IMPORTANT
A Flame Detection System is required for opera-
tion and must be ordered separately. Select the
applicable Flame Signal Amplifier and matching
Flame Detector from form number 65-0109.

INSTALLATION

When Installing this Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2. Check the ratings given in the instructions and
marked on the product to make sure the product is
suitable for the application.
3. Installer must be a trained, experienced, flame safe-
guard service technician.
4. After installation is complete, check out the product
operation as provided in these instructions.
WARNING
Explosion or Fire Hazard. Can cause severe
injury, death or property damage.
Observe applicable local safety requirements each time a
control is installed on a burner.
WARNING
Electrical Hazard or Equipment Damage Hazard.
Can cause electrical shock or equipment and
control damage.
Disconnect the power supply before beginning
installation. More than one power supply disconnect may
be required.

Continuous Operation Note
Non-check amplifiers cannot be used in continuous
operation (per EN298). For continuous operation only
ampli-check or shutter/self-check flame amplifiers are
used.
Non-check amplifiers trigger the device to automatically
recycle after 24 hours when in a continuous run mode.
IMPORTANT
1. Wiring connections for the relay modules are
unique; refer to Fig. 2 and 3 or the correct Specifi-
cations for proper subbase wiring.
2. Wiring must comply with all applicable codes,
ordinances and regulations.
3. Wiring must comply with NEC Class 1 (Line Volt-
age) wiring.
4. Loads connected to the 7800 SERIES Relay Mod-
ule must not exceed those listed on the 7800
SERIES Relay Module label or the Specifications;
see Table 4.
5. Limits and interlocks must be rated to simultane-
ously carry and break current to the ignition trans-
former, pilot valve, and main fuel valve(s).
6. All external timers must be listed or component
recognized by authorities who have proper juris-
diction.
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 Flame Detectors can be connected in parallel
with the exception of low voltage C7915 Infrared
Flame Detectors and C7927, C7961 Ultraviolet
Flame Detectors.
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.
The EC7820A complies with the requirements of
EN 50081 (European Radiated Emission Stan-
dard). It has been tested and found to provide rea-
sonable protection against such interference
when operated in a commercial environment.
Operation of this equipment in a residential area
may cause interference; in which case, the users at
their own expense may be required to take what-
ever measures are required to correct this interfer-
ence.
See Fig. 2 for the internal block diagrams of the EC7820A
Relay Modules.
Location
Humidity
Install the relay module where the relative humidity never
reaches the saturation point. The relay module is designed
to operate in a maximum 85 percent relative humidity
continuous, noncondensing, moisture environment.
Condensing moisture may cause a safety shutdown.
Vibration
Do not install the relay module where it could be subjected
to vibration in excess of 0.5G continuous maximum
vibration.
