INSTALLATION
When Installing this Product…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous 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 safeguard
service technician.
4. After installation is complete, check out the product opera-
tion as provided in these instructions.
WARNING
Fire or Explosion Hazard.
Can cause property damage, severe injury, or death.
Follow applicable safety requirements when installing a
control on a burner to prevent death or severe injury.
WARNING
Electric Shock Hazard.
Can cause serious injury, death or equipment damage.
Disconnect power supply before beginning
installation.
IMPORTANT
1. Wiring connections for the relay modules are unique; refer
to Fig. 2 and 3 or the appropriate Specifications for proper
subbase wiring.
2. Wiring must comply with all applicable codes, ordinances
and regulations.
3. Wiring must comply with NEC Class 1 (Line Voltage) wir-
ing.
4. Loads connected to the RM7895A,B,C,D/EC7895A,C;
RM7896A,B,C,D must not exceed those listed on the
RM7895A,B,C,D/EC7895A,C; RM7896A,B,C,D label or
the Specifications; see Table 1.
5. Limits and interlocks must be rated to simultaneously
carry and break current to the ignition transformer, pilot
valve, and main fuel valve(s).
6. All external timers must be listed or componentrecog-
nized 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 flame detectors can be connected in parallel
with the exception of Infrared Flame Detectors (C7915).
9. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accor-
dance 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 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 re-
quired to take whatever measures are required to correct
this interference.
10. This digital apparatus does not exceed the Class B limits
for radio noise for digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.
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% relative humidity continuous,
noncondensing, moisture environment. Condensing moisture
can cause a safety shutdown.
Vibration
Do not install the relay module where it can be subjected to
vibration in excess of 0.5G continuous maximum vibration.
Weather
The relay module is not designed to be weather tight. When
installed outdoors, protect the relay module in an approved
weather-tight enclosure.
Mounting Wiring Subbase
1. Mount the subbase in any position except horizontally with
the bifurcated contacts pointing down. The standard verti-
cal position is recommended. Any other position decreases
the maximum ambient temperature rating.
