GAS SPILLAGE SENSING KIT

Model: GSK-3, GSK-4, GSK-250M

Installation of a spillage SAFETY Switch is recommended for LP and Natural gas fired systems with draft
hoods, draft diverter, or 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 Swit ch

INSTALLATION ON DRAFT HOODS
I

N-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.

B

UILT-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.

V

ERTICAL 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)
