Preventing Damage from Freezing / Regular Maintenance
1. Check that all drain plugs are inserted.
2. Check that all hot water fixtures/faucets are
closed.
3. Open the water supply valve.
4. Open a hot water fixtures/faucets to confirm
that water is available, and then close the hot
water fixtures/faucets again.
5. Open the gas supply valve.
6. Connect the electrical power.
Do not touch with wet hands.
7. Make sure that the area around the appliance
is well ventilated; open a window or a door
if necessary. Then, operate the Water Heater
and verify that condensate is coming out of
the condensate drain pipe. (During normal use
of the Water Heater, condensate will begin to
discharge from the condensate drain pipe within
15 minutes of use. However, depending on the
season and/or installation site conditions, it may
take longer.)
Turning the Water Heater Back On
NOTE
If water does not appear at the end
of the drain line, a qualified service
technician must clean the condensate
line.
After the Water Heater has been out of use for a
long time, make sure that you fill the condensate
trap with water.
This is to prevent dangerous exhaust gases from
entering the building.
Failure to fill the condensate trap could result in
severe personal injury or death.
(By performing step 4 as described below, the
condensate trap will automatically fill itself with
water.)
