It takes a long time to
get hot water at the
fixtures .
•
The time it takes to deliver hot water from the water heater to your fixtures depends
on the length of piping between the two . The longer the distance or the bigger the
pipes, the longer it will take to get hot water .
•
If you would like to receive hot water to your fixtures quicker, you may want to
consider a hot water recirculation system . (pg . 21)
The water is not hot
enough .
•
Compare the flow and temperature . See the charts on pg . 41 .
•
Check cross plumbing between cold water lines and hot water lines .
•
Is the gas supply valve fully open? (pg . 22)
•
Is the gas line sized properly? (pg . 15)
•
Is the gas supply pressure enough? (pg . 15)
•
Is the set temperature set too low? (pg . 25)
•
Is Easy-Link set up correctly in a Multi-Unit System? (pg 18 to 20)
•
If a mixing valve is used in your system, is it blending?
The water is too hot .
•
Is the set temperature set too high? (pg . 25)
The hot water is not
available when a fixture
is opened .
•
Make sure the unit has 120 VAC, 60 Hz power supply .
•
If you are using the remote controller, is the power button turned on?
•
Is the gas supply valve fully open? (pg . 22)
•
Is the water supply valve fully open? (pg . 22)
•
Is the filter on cold water inlet clean? (pg . 27)
•
Is the hot water fixture sufficiently open to draw at least 1 .9 L/min (0 .5 GPM (US))
through the water heater? (pg . 25)
•
Is the unit frozen?
•
Is there enough gas in the tank/cylinder? (For Propane models)
•
Is it plumbed back with reverse plumbing?
•
If your water heater is used in a dual purpose installation with a check valve,is the
check valve defective? Check for cross plumbing .
•
If your installation is Multi-Unit, is Easy-Link set up correctly?(pg,18 to 20)
The hot water turns
cold and stays cold .
•
Is the flow rate enough to keep the water heater running? (pg . 25)
•
If there is a recirculation system installed, does the recirculation line have enough
check valves? (pg . 21)
•
Is the gas supply valve fully open? (pg . 22)
•
Is the filter on cold water inlet clean? (pg . 27)
•
Are the fixtures clean of debris and obstructions?
•
Check if the flow rate is too low . (pg . 25)
Fluctuation in hot water
temperature .
•
Is the filter on cold water inlet clean? (pg . 27)
•
Is the gas line sized properly? (pg . 15)
•
Is the supply gas pressure sufficient? (pg . 15)
•
Check for cross connection between cold water lines and hot water lines .
•
Is Easy-Link set up correctly?(pg . 18 to 20)

Unit does not ignite
when water goes
through the unit .
•
Is the power on to the water heater?
•
Is the gas on?
•
Is the flow rate over 1 .9 L/min (0 .5 GPM (US))? (pg . 25)
•
Check for the filter on cold water inlet . (pg . 27)
•
Check for reverse connection and cross connection .
•
If a remote controller is connected, is it powered on?
•
Check if the inlet temperature is too high .
The fan motor is still
spinning after operation
has stopped .
•
This is normal . After operation has stopped, the fan motor keeps running from 15 to
70 seconds in order to re-ignite quickly, as well as purge all the exhaust gas out of
the flue .
