Maintenance (once a month)
If the water filter is covered with debris, the hot water will not run smoothly, or cold water may
come out. Clean the filter as explained below.
* To avoid burns, wait until the equipment cools down before draining the water. The
appliance remains hot after it is turned off.

Hot water is not available when
the hot water fixture is opened.
•
Are the gas and water supply valves fully open?
•
Is the water supply cut off?
•
Is the hot water fixture sufficiently open?
•
Is the heater frozen?
•
Is the gas meter working?
•
(For LP) Is there enough gas in the tank?
•
Is the operation button turned on?
•
Have you allowed enough time for the cold water in the
pipes to drain out?
•
Are the gas and water supply valves fully open?
•
Is the water temperature setting appropriate (
p.12
and p.13)?
•
If the supply water is at a high temperature, you may
need to increase the flow rate through the heater to get
a low temperature out of it.
Hot water is not available at low
temperatures.
Cold water comes out when the
fixture is barely opened. Only
cold water is available at low
flow rates.
•
The heater stops burning when the flow of hot water
becomes less than 0.75 GPM. Open the hot water
fixture more, and the water temperature will stabilize.
