MODEL GS28 ONLY: SPILL SWITCH
This is a thermally activated switch, attached to the back of the chimney adaptor, which senses the change in
temperature and shuts down the gas valve in the event of a blocked or disconnected vent. It acts as a safety
shut-off to prevent a build up of carbon monoxide or an explosion of unburned gases during start up. If the fl ue is
blocked or has no "draw", the spill switch will automatically shut off the supply of gas within about 5-10 minutes.
MODEL GS28 ONLY: VENTING ACTION CHECK
A CHECK FOR CORRECT VENTING ACTION MUST BE MADE BEFORE THE INSTALLED APPLIANCE IS LEFT
WITH THE CUSTOMER. Test in the following manner:
A.
Close all doors and windows in the room / start exhaust fans in the home / turn appliance blower off (if
