is on the rating plate and the label on the side of the gas
valve control. Poor flames can also be caused by incorrect gas
pressures or burner orifice size, inadequate or contaminated
air, a restriction in the venting system, or dirt entering the
gas supply. These conditions must be corrected to prevent a
possible safety hazard.
• For units with cast iron burners, the flame presentation
should be the same as sheet metal burners. Adjustment is
possible on cast iron burners by changing the air shutter
position on the burner inlet. If the flame needs adjusting,
loosen the two screws and move the shutter. See Figure 12.
If it is too far open, the flame will lift or will be noisy; if it is
closed too far, the flame will be luminous and yellow. Once
proper flame is obtained, tighten the screws to secure the
air shutter.
NOTE: Ø There is no adjustment on sheet metal
burners.
Ø Always return the burner doors to their
original position
VII) GENERAL OPERATION AND
MAINTENANCE
Condensation
Water vapor in the flue gases can condense on the cooler
surfaces of the water heater, especially during the start of a
cold tank, during heavy use, or if the water heater is undersized.
Condensation can also be produced in the vent piping if the vent
piping becomes chilled (e.g. going through unheated areas) or if
the dilution air is very cold.
Condensation may give the false impression that there is a tank
leak as significant amounts can drip out of the bottom of the
water heater. Once the water heater is operating at normal
temperatures tank condensation should disappear. See venting
section for dealing with condensation in the vent piping.
Cathodic Protection - Anode
Your water heater has been supplied with an anode rod that
protects the tank from corrosion, As the rod works, it slowly
dissolves over time and must be replaced when it becomes totally
consumed. Depending on water conditions, an anode can last from
two to ten years. As with any water heater, it is good practice to
check the anode annually to see if it needs replacing (Figure 1,
Item No. 15).
To inspect or change an anode:
• turn off the water heater
• close the cold inlet supply valve
• open a hot water tap supplied by the heater
• drain the water heater enough to empty the piping system
• using a 1

" socket, remove anode and inspect or replace as
required.
• refill system with water and restore water heater to
operation
WARNING
Operating a water heater without an actively working anode rod
will void the warranty.
Hot Water Odour
On occasion, and depending on your location, hot water may
develop a strong odour. This can be especially problematic in
regions where the water contains some sulphur, which results in
hot water having a “rotten egg” smell.
If this occurs, drain the system completely, flush thoroughly and
refill. If the problem persists, the anode rod may need to be
changed from magnesium to one made of aluminum. In certain
cases chlorination and flushing of the water heater may be
required. Contact you dealer or water supplier.
Not Enough or No Hot Water
• Check that the water heater is operational
• Check that the thermostat is set high enough
