GAS SPILLAGE SENSING KIT
Model: GSK-3
Installation of a spillage SAFETY Switch is recommended for
LP and Natural gas fired systems with draft hoods, draft
diverter, and gas barometric draft controls. This device is
installed to detect flue gas spillage caused by a blocked flue
system and/or inadequate draft. This device MUST be installed
by a qualified installer in accordance with the manufacturer's
installation instructions. Wiring MUST be in accordance with the
National Electrical Code and applicable local codes.
Before and after adding this safety control on existing
appliances, an installation inspection in accordance with the
National Fuel Gas Code 54, Z223.1 Appendix H should be
performed and a combustion analysis is recommended to
determine the operating condition of the appliance.
CAUTION: Disconnect Electrical Power When Wiring Spillage

INSTALLATION ON DRAFT HOODS
IN-LINE HORIZONTAL DRAFT HOOD (See Figures 1 & 2)
1. Two (2) switches are recommended on these hoods. Mount the
switches approximately 2 1/2 inches from the opposite ends and
sides of the draft hood opening. (See Figure 1)
2. The switch should not contact the metal. They should be mounted at
least 3/4 inch below the hood opening. (See Figure 2) Mount with
supplied sheet metal screw.
BUILT-IN DRAFT HOOD (See Figures 3 & 4)
1. Two (2) switches are recommended on appliances without a factory
supplied spill switch. Mount the switches approximately 3 inches
from the side of the draft hood opening and the second switch (if
used) 3 inches from the opposite side of the draft hood. (See Figure
3) If the appliance has a factory built-in switch, mount a single switch
3 inches from the side opposite the factory switch.
2. The switch should not contact the metal. They should be mounted at
least 1 inch below the hood opening. (See Figure 4) Mount with
supplied sheet metal screw.
VERTICAL DRAFT HOOD
(See Figures 5 & 6 or Figure 13 for water heaters)
1. Two (2) switches are recommended on appliances without a factory
supplied spill switch. Mount the spill switch onto the bottom edge of
the draft hood and the second switch (if used) approximately 90
degrees from the first switch or 90 degrees from the factory supplied
switch. (See Figure 5)
2. The switch should not contact the metal. They should be mounted at
least 3/4 inch below the hood opening. (See Figure 6) Mount with
supplied sheet metal screw.

DRAFT CONTROLS (See Figures 7 & 8)
NOTE: GSK style switches are designed for draft control models 4" MG1 through 9"
MG1. Larger size draft controls require the FTS Series switches.
1. Locate the spill switch along the bottom edge of the draft control ring. (See Figure 7)
Mark and drill a 5/32" dia. hole through the ring.
2. Mount the switch with the supplied #5-40 machine screw and nut. Note, the head of
the screw is to be on the inside of the ring. (See Figure 8)
3. Swing the gate to make sure the gate does not hit the screw head or the switch.
NOTE: Mounting the spill switch on the top of the draft control ring will function properly,
but will react slower during a block flue condition.
WIRING
CAUTION: When wiring the spillage
switch into the burner circuit route the
wiring and secure away from any hot
surface. Shut off all electrical power and
gas supply to the appliance before
working with any electrical connections.
24 VOLT APPLICATIONS
1. Disconnect the hot lead between the
thermostat or temperature control and
the TH terminal on the gas valve or
the TH,TH-W or 24V terminal on the
ignition module. Check the thermostat
anticipator (if applicable) circuit for
proper setting.
CAUTION: Never wire to the 24V
GND terminal.
2. Wire the spill switch or switches into
series with this circuit by wiring from
the thermostat or temperature control
to the spill switch or switches then to
the gas valve or ignition module. (See
Figure 9 & 10)

750 MILLIVOLT PILOT GENERATOR APPLICATIONS
1. Disconnect the hot lead between the thermostat and the TH
terminal on the gas valve. On older bleed tube style
equipment split one lead of the E.C.O. (energy cut off)
circuit.
2. Wire the spill switch or switches into series with this circuit
by wiring from the thermostat to the spill switch or switches
then to the TH terminal on the gas valve. On older bleed
tube style equipment wire switches in series with one wire
of the E.C.O circuit. (See Figure 11)
30 MILLIVOLT WATER HEATER:
Two (2) switches are recommended for this application. The
application requires a TCA-1 Thermal Couple Junction block
(P/N 46082700 NOT INCLUDED) and a 6 foot length of 12 ga.
two (2) wire conductor (NOT INCLUDED) to wire between the
spill switches and the TCA-1.
CAUTION: Shut off gas supply before working on appliance.
1. Remove thermocouple from gas control valve. (See Figure
12)
2. Thread the junction block into the thermocouple port and thread
the thermocouple into the bottom of the junction block.
3. Mount the two (2) spill switches onto the draft hood so the
switches do not contact any metal. (See Figure 13)
4. Connect the one terminal of each switch with 12 ga wire and then
connect it to the thermocouple junction block. Next,connect the two
remaining terminals together using a short length of 12 ga wire.
(See Figure 14)
5. Route and secure the wires to the water heater enclosure with acceptable hold down
tabs, keeping the wires away from any hot surface area.
SYSTEM CHECK-OUT PROCEDURE FOR GAS SPILLAGE SWITCH CONTROL
1. Shut off gas supply to appliance(s).
2. Block the flue pipe above the draft control, draft hood or draft diverter.
3. Re-establish gas supply to appliance and re-light pilot (if required).
4. Adjust thermostat to call for heat.
5. Flue gases should be emitting from draft control, draft diverter or draft
hood. Note the location of the most flue gas spillage. Allow approximately
2 minutes for the system to back up and the gas burner to shut down.
Wait 2 to 3 minutes, reset switches, and re-light pilot. If the spillage
switch dose not trip within the 2 minute period, relocate the switch onto
the area where the observed highest spillage occurred. Then perform this
test again.
CAUTION: If for any reason the system has shut down during normal
operation, the cause of the system failure should be investigated and
corrected before resetting the safety switch and relighting the pilot.
