37° and 60°.
Possible Causes
There is no gas, water or
electricity flowing to unit.
The system requires
approximately 0.6 gpm
minimum flow to activate
the heater.
If the flow from the tap was
adjusted to lessen it, the flow
may have gone below the
minimum required.
During colder weather, when
the exhaust temperature is much
hotter than the outside air, the
exhaust fumes condense,
producing water vapor.
Hot water must travel through the
plumbing from the water heater to
the faucet. The time period for hot
water to reach the fixture is determined
by the amount of water in the plumbing
system between the water heater and the
fixture, water pressure and the flow rate
of the fixture.
The fan is designed to continue running
for a short time after the flow of water stops.
This is to ensure constant water temperatures
during rapid starting and stopping, as well as
exhausting any residual gas flue products
from the unit.
