(INSTALL GOKIT7200-1)
1. Disconnect thermocouple(C) from the water heater'sgasvalve(D).
CAUTION
Do not use teflon tape orothersealantonanyoftheseconnections.2. Screw provided gas valveadapter(E) intogasvalve(D).
3. Re-insert thermocouple (C) into femalethreadofgasvalveadapter(E) andscrewnuttwo full turnsonly. Insert roundwhiteplugofwiring harness (F) into adapter hole. Tightenthermocouplenut(C) securely.4. Removeanddiscardthefusecover(G) fromthe WAGS valve terminals and insert thewiringharness’sblueconnectors.Pressfirmly.
5. Theplasticself-adheringmountingpad (H)

NOTE TO HOMEOWNER
To ensure proper operation, keep the waterintakeslotsonthebottomoftheplasticsectionof the WAGS valve free and clear. Inspectperiodically.

INSTALLATION STEPS
To install the WAGS valve on an existing waterheater without a drip pan begin at step 1. Toinstall the WAGS valve on a new waterheater installation or if your water heateralready has a pan installed begin at step 6.See special additional steps for gas and oilheater installation following step 14.
INSTALLATION OF AN EXISTING
WATER HEATER WITHOUT A DRIP PAN
1. Turnoff supplywaterandgas/electricity tothewaterheater.2. Extinguish all flames in the work area,includingpilot lights.Turnthermostatsonanyboilersorfurnacestothelowestsetting.3. Drain thewater heater completely by con-nectingagardenhosetothedrainvalve.(Turnonanyhotwaterfaucetinthehousetobreakthevacuum.)4. Disconnectthehotandcoldwaterlinesfromthewaterheater.Iftherearenounionconnec-tions,cutthepipesatleast3inchesabovethetopofthewaterheater.5.
