4” x 5” x 2 ½”
101 x 127 x 64 mm
This interface Adaptor RADP-0242-S10A is an
interlocking control device to safely supply fresh air
for a dryer/damper/furnace combination. The
Adaptor has a manual red light switch that, when
turned on, the fresh air damper opens proving its
position prior to gas dryer operation (Interlocked).
This Adaptor may also be interconnected to
simultaneously turn on a Furnace Circulation Fan
and open an HAC replacement air damper, if used,
on a furnace return plenum. HAC Damper may
also open during furnace firing. Damper(s)
remain open until the red light switch is manually
turned off.
This Adaptor may be interlocked to dampers:
-HOM-0x11-SF1
-HOM-0x12-SF2, secondary circuit;
-HAC/MAC-0x11-SPC;
-HAC/MAC-0x10-SPO;
Fitness of this Adaptor/Damper combination to
satisfy air supply requirements for fuel fired
appliances during operation of the
interconnected 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 2006, ANSI Z223.1 and/or
local codes including local codes relating to
ventilation air duct installation.

- Refer to local and applicable codes.
- Always conduct a thorough check-out after
Installation is complete.
- Affix appropriate labels and follow
Instructions and warnings on each label.
1. Dampers HOM-0x11-SF1 or MAC-0x11-SPC
used for air supply to the Gas Dryer only:
a) Mount the Adaptor near the Gas Dryer for
ease of Red Light Switch operation and near
the 120Vac outlet that was used for the dryer.
b) Use 2C-18Ga. electrical wire to connect
Damper terminals #4(common) and #5(live) to
24Vac supply. If using the heating appliance
transformer, check transformer capacity.
c) Run 4C-18Ga. electric wire from the Damper to
the Adaptor and connect as follows:
-Connect HOM/MAC Damper #4 to RADP #3(C)
-Connect HOM/MAC Damper #3 to RADP #8
-Connect HOM/MAC Damper #2 to RADP #1
-Connect HOM/MAC Damper #1 & #5 to RADP #2.
d) Turn on the electric power to the Damper
causing the damper to close.
e) Plug the Adaptor cord into the 120Vac outlet.

f) Plug the dryer cord into the ‘GAS DRYER’ side
of the Adaptor Receptacle.
g) Turn on the Adaptor Red Light Switch.
The Fresh Air Damper will open and the
Gas Dryer is ready to be set for its operation.
h) After the drying cycle is complete, turn the Red
Light Switch off and the damper will close.
2. Damper HOM-0x12-SF2 used for the DUAL
PURPOSE of supplying combustion air to
both a heating appliance and to a Gas Dryer:
Note: Confirm HOM-0x12-SF2 damper is
properly working with primary furnace before
connecting to the Gas Dryer. Refer to the
Installation Instructions supplied with the
Combustion Air Damper to confirm its proper
operation.
a) Mount the Adaptor next to the Gas Dryer for
ease of Red Light Switch operation and near
the 120Vac outlet that was used for the dryer.
b) Turn off the appliance power to the HOM-0x12-
SF2 Combustion Air Damper.
c) Run a 5C-18Ga. electric wire along the gas line
from the Heating Appliance electrical circuit to
the RADP-0242-S10A Adaptor.
d) Connect the secondary circuit of the HOM
Combustion Air Damper, the Adaptor and
the Heating Appliance as follows:
-Connect HOM Damper #6 to Adaptor #2 and
to the Heating Appliance ‘R’ (24Vac);
-Connect HOM Damper #7 to Adaptor #1;
-Connect HOM Damper #8 to Adaptor #8.
-Connect Adaptor #3(C) to the Heating
Appliance ‘C’ or to a ground screw.
e) Turn on the electric power to the heating
appliance. The Combustion Air Damper will
close.
f) Plug the Adaptor cord into the 120Vac outlet.
g) Plug the dryer cord into the ‘GAS DRYER’ side
of the Adaptor Receptacle.
h) Turn on the Adaptor Red Light Switch.
The Combustion Air Damper will open and the
Gas Dryer is ready to be set for its operation.
i) After the drying cycle is complete, turn the Red
Light Switch off and the damper will close.
3. When a heating system is equipped with a
REPLACEMENT AIR SUPPLY DUCT leading
into the return plenum, the Furnace
Circulation Fan may be turned on to assist air
movement to the dryer:
a) For thermostats having an ‘automatic
/manual’ fan switch:
- disconnect thermostat wire from furnace ‘G’ and
connect to Adaptor #6(Gt)
- connect Adaptor #7(Gf) to furnace ‘G’.
b) Turn on the Adaptor Red Light Switch.
The air supply damper will open, the furnace
circulation fan will run and the Gas Dryer is ready
to be programmed for its operation.
c) After the Gas Dryer has finished its cycle,
turn the Adaptor Red Light Switch off. The
furnace circulation fan will stop and the
air supply Damper will close.
4. A REPLACEMENT AIR CONTROL DAMPER
HAC-0x10-OPO/PC on a fresh air
duct leading into the return plenum may be
used provided it is interconnected to open
simultaneously with the furnace circulation
fan when the Red Light Switch is turned on:
a) For the HAC damper Power Open type:
- Connect one HAC damper wire to ‘C’ or a
ground screw on the furnace
- Connect the other HAC damper wire to
Adaptor #5.
b) For the HAC damper Power Close type:
- Connect one HAC damper wire to ‘C’ or a ground
screw on the furnace
- Connect the other HAC damper wire to
Adaptor #4.
5. IF REPLACEMENT AIR CONTROL DAMPER
HAC placed on a fresh air duct leading
into the return plenum is required to OPEN
DURING FURNACE FIRING:
a) Use 18 ga. wire and connect Adaptor #9 to the
‘W’ terminal of the furnace.
b) Damper will open during firing of the furnace
and close when the fire stops.
