The water heater is not subject to corrosive
compounds in the air.
□
The water supply does not contain chemicals or

□
For indoor models, verify that the vent system
does not exceed the maximum length for the
number of elbows used.
□
For indoor models, verify that switch No. 1 in the
SW1 DIP switch (tan switches) has been adjusted
for vent length if necessary. Refer to the sec on
on Maximum Vent Length.
□
For indoor models, verify that the vent pipe has a
downward slope or grade to the outside of 1/4
inch per foot (1.2º) OR if the vent pipe is sloped
toward the water heater (as some local codes
require), that a condensate collector is installed
to allow condensa on to drain away from the
water heater to a proper drain source.
□
For indoor models, verify that condensate will not
be allowed to drain back into the water heater.
□
Purge the water line of all debris and air by
closing the hot isola on valve and opening the
