Preventing Damage from Freezing-3
Turning the Unit Back On
1. Check that all drain plugs are inserted.
2.Checkthatallhotwaterxtures/faucets are closed.
3. Follow the procedure on p.16 “Initial operation”, steps 1 through 4.
4. Make sure that the area around the appliance is well ventilated; open a window or a door if necessary.
Then, operate the unit and verify that condensate is coming out of the drain pipe.
(During normal use of the water heater, condensate will begin to discharge from the drain pipe within 15
minutes of use. However, depending on the season and/or installation site conditions, it may take longer.)
*Ifwaterdoesnotappearattheendofthedrainline,aqualiedservicetechnicianmustcleanthe
condensate line.
Afterthewaterheaterhasbeenoutofuseforalongtimemakesurethatyoull
the condensate trap with water.
This is to prevent dangerous exhaust gases from entering the building.
Failuretollthecondensatetrapcouldresultinseverepersonalinjuryordeath.
(By performing step 4 as described above, the condensate trap will automatically
llitselfwithwater.)
Be sure to do.
