Due to the high-efficiency rating of this gas-fired 
water heater, it may produce more condensation than 
older models. Condensation forming on the flue tube 
will drop on the burner making a “sizzling” sound. In 
extreme cases, the condensation may even extinguish 
the pilot flame. This condition is not uncommon and 
must never be misinterpreted as a leaking tank. It will 
disappear once the water becomes heated.

Because of the large amounts of water that can 

 

condense, it is very important that a drain pan be 
installed under the water heater (refer to Figure 10). 
Under no circumstances is the manufacturer to be 
held liable for any water damage, in connection 
with this water heater
. If the problem does not go 
away and water continues to drip after the water heater 
has heated up, check all of the plumbing connections to 
make sure they are not leaking. 

Burner Ignitor Assembly
Every three (3) months, check the burner and flame ignitor 
assembly. Remove the outer access door and look 
through the sight glass to examine the flames. A soft blue 
flame indicates proper gas combustion. A yellow tipped 
flame indicates poor combustion. With a vacuum cleaner, 
remove any dust, lint, and dirt accumulation on or around 
the combustion chamber and in the combustion air 
intake holes.

Water Heater Tank
Drain a pail of water through the drain valve at least 
once a year. This will remove excess sediment from the 
bottom of the tank. This sediment, if allowed to accumu-
late, will reduce the efficiency and the life of the tank.

Temperature and Pressure-Relief Valve
Manually operate the temperature and pressure-relief 
valve at least once a year, standing clear of the outlet to 
avoid being burned. Lift and release the operating lever 
on the valve to make it operate freely. If, after manually 
operating the valve, it fails to completely reset itself and 
continues to discharge water, replace it with a new one.

Venting System Inspection
The venting system must be thoroughly inspected 
once  a year. Check the area where the water heater  
is located to make sure that there is enough clean 
combustion and ventilation air. Remove any possible 
obstructions that would prevent proper air circulation 
and venting. Check the venting system to make sure 
that all of the connections are securely fastened, and 
that all of the joints are properly sealed. If any part of 
the venting system is damaged, it must be replaced by 
a qualified service technician. 

Anode rods
This water heater is equipped with two (2) anode rods that 
are designed to prolong the life of the glass-lined tank. 
The anode rods are slowly consumed, protecting the  
glass-lined tank from corrosion. The anode rods 
should be checked every two (2) years. If more than 
half of any anode rod has been consumed, it should 
be replaced. Instructions on how to change an anode 
rod can be obtained from the manufacturer.

The life expectancy of the water heater is reduced 
where a water softener is introduced to fight hard 
water,  because the sodium salts added by a soft-
ener make this water extremely conductive. In these  
conditions, the anode rods are consumed more rapidly 
and should be verified every year.

In certain water conditions, the magnesium of the stan-
dard anode rods will react with the water, producing dis-
coloured or smelly water. The most common complaint 
is hot water that smells like rotten eggs. This phenom-
enon is the result of the reaction between the magne-
sium and hydrogen sulfide gas dissolved in the water, 
which occurs frequently  in well systems. This problem 
can usually be eliminated or reduced by changing the 
anode rods to a type more suitable for these conditions 
(aluminum anode rods) and by chlorinating the water 
heater and plumbing system. If the problem persists, 
special filtration equipment may be required. Under no 
circumstances are the anode rods to be removed from 
the water heater on a permanent basis. Removal of the 
anode rods will lead to premature failure of the water 
heater and void the warranty
.

Hydrogen gas can be produced in a hot water sys-
tem that has not been used for a long period of time  
(generally two [2] weeks or more). HYDROGEN GAS 
IS EXTREMELY FLAMMABLE
. It is highly recom-
mended to open the hot water faucet in the kitchen for 
several minutes before you use any electrical appli-
ances connected to the hot water system, such as a 
dishwasher or washing machine. If hydrogen gas is 
present, there will be an unusual sound, such as air 
escaping through the pipe, as the hot water faucet is 
opened. 

DO NOT

 smoke or introduce an open flame 

near the faucet when it is opened.

Draining the Water Heater 
To completely drain the water heater:

1)  Unplug the power cord from the wall socket.
2)  Close the gas supply manual shut-off valve.
3)  Close the cold water supply manual shut-off valve.
