INSTALLATION OF THIS ADAPTOR SHALL BE
IN ACCORDANCE WITH THE REQUIREMENTS
OF THE AUTHORITIES HAVING JURISDICTION
Refer also to HOYME Installation Instructions:
Combustion Air Control Damper, Series HOM;
Replacement/Ventilation Air Control Damper,
Series HAC; and Adaptor ADP- 1101- 05A.
ADP-0241-05A
4” x 5” x 2 1/2”
101 x 127 x 64 mm
This Relay Adaptor may be used as an automatic
switch having a
24Vac Coil
and
120Vac points
to
control a line voltage circuit for up to a 5 amp
draw such as a 120Vac exhaust fan. All the points
can also be used for 24Vac switching. (See wire
diagrams on next page.)
A typical application where all the points are used
for 24Vac switching may occur when dry points
are used at the exhaust fan switch. When the
exhaust fan switch is turned on, the furnace fan
and the fresh air damper, if used, will open
simultaneously. The fresh air damper, however,
will not open for furnace firing.
If the damper is required to open when the
appliance fires:
a)
Refer to wiring diagram (next page) showing
the
Power Close Damper with Relay;
- or -
b)
Use a
regular fresh air damper
with an
ADP-
0242-05A
and follow its Installation Instructions;
- or -
c)
If controlled line voltage is available from the
exhaust fan, use
Adaptor ADP-1102-TWP
and
follow its installation instructions.
Fitness of this Adaptor/Damper combination,
to satisfy air supply requirements for fuel fired
appliances during operation of the
Inter-connected exhaust fan(s), shall be
investigated by the enforcing authorities.
Air intake duct installation shall be in accordance
with: In Canada - CAN/CSA B149 & B139; In the
USA – ANSI/NFPA 54, 2006, ANSI Z223.1 and/or
local codes including local codes relating to
ventilation air duct installation.
I.D.: ADP-0241-05A
; comes with one relay.
DPDT-Coil-24Vac. Pts-24V & 120Vac- 5Amps.
- One adaptor is required for each heating
appliance.
- Adaptor line voltage leads, connected to the
appliance shall be suitably cabled, fastened and
enclosed in suitable raceways.
- Refer to local and applicable codes.
- If an auxiliary transformer is required, use an
approved 24Vac transformer of adequate
capacity.
- Supply for the transformer primary shall be
taken from the line voltage supply of the
appliance. Refer to applicable codes.
- Always conduct a thorough check-out after
installation is complete.
- Affix appropriate labels and follow
instructions and warnings on each label.
1. Install motorized air control damper as per
instructions supplied with it. Satisfactory
operation of the damper is recommended
before interconnecting Adaptor.
2. Turn off electrical power supply to the
appliance.
3. Connect Adaptor line voltage leads to fan motor
circuit as per wiring diagram and applicable
codes.
4. Connect 24Vac Damper terminal wires to
appropriate Adaptor, transformer and control
switches. (See damper wiring diagram for proper
circuit.)
5. Turn on electrical power to 24Vac transformer.
If damper is a Power Open type, it will remain
closed at this time. If damper is a Power Close
type, it will close at this time.
6. Turn on selected switches at least 3 times to
verify the intended operation of selected circuits.
