therefore, refer to Fig. 5 or the correct Specifications
for proper subbase wiring.
2.
Wiring must comply with all applicable codes,
ordinances and regulations.
3.
Wiring, where required, must comply with NEC Class
1 (Line Voltage) wiring.
4.
Loads connected to the RM7895 must not exceed
those listed on the RM7895 label or the Specifica-
tions, see Table 1.
5.
Limits and interlocks must be rated to carry and
break current simultaneously 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 jurisdiction for
the specific purpose for which they are used.
IMPORTANT
1. 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).
2. Two flame detectors can be connected in parallel.
3. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and
used in accordance with the instructions, may
cause interference to 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 user, at
their own expense, may be required to take
whatever measures are required to correct this
interference.
4. This digital apparatus does not exceed the Class B
limits for radio noise of digital apparatus set out in
the Radio Interference Regulations of the Cana-
dian Department of Communications.
Humidity
Install the RM7895 where the relative humidity (RH) never
reaches the saturation point. The RM7895 is designed to
operate in a maximum 85 percent RH continuous,
noncondensing, moisture environment. Condensing
moisture may cause a safety shutdown.
Vibration
Do not install the RM7895 where it could be subjected to
vibration in excess of 0.5G continuous maximum
vibration.
Weather
The RM7895 is not designed to be weather tight. If
installed outdoors, the RM7895 must be protected by an
approved, weather-tight, enclosure.
Mounting Wiring Subbase
NOTE:
For installation dimensions, see Fig. 1.
1.
Mount the subbase in any position except
horizontally with the bifurcated contacts pointing
down. The standard vertical position is
recommended. Any other position decreases the
maximum ambient temperature rating.
2.
Select a location on a wall, burner or electrical panel.
The Q7800 can be mounted directly in the control
cabinet. Be sure to allow adequate clearance for
servicing, installation, access and removal of the
RM7895, Dust Cover, flame amplifier, flame
amplifier signal voltage probes, electrical signal
voltage probes and electrical field connections.
