The gas control valve pictured in this manual is equipped

with a single-use type automatic high temperature cut-off.

Should the temperature of the water exceed 195

F (91

C),

the high temperature cut-off will automatically shut off the

gas supply to the water heater. If this situation occurs, the

gas control valve must be replaced immediately replaced by

EnerCare.

WARNING

CAUTION

AVERTISSEMENT

ATTENTION

Should overheating occur or the gas supply fail to shut

off, close the gas supply manual shut-off valve. Failure

to follow this instruction can result in property damage,

personal injury, or death.

Out of Fuel

If your water heater should run out of gas call EnerCare
Home Services at 1-866-554-5591 and let them know your
situation.

Housekeeping

Keep the area around the water heater clean and free of dust,

lint, and dirt. It is the responsibility of the homeowner to do

so in order to prevent any malfunc tion that is not EnerCare’s

responsibility.

ATTENTION

DO NOT

store or use gasoline or other flammable

vapours and liquids around the water heater.

DO NOT

put or store any objects on the top of the water

heater. Failure to follow these instructions can result in

property damage, personal injury, or death.

Flammable Vapour Sensor

This water heater is equipped with a flammable vapour sen-
sor (FV) that will shut it down in the event of a flammable
vapour incident. It is a safety feature that may prevent prop-
erty damage, personal injury, or death.

The FV sensor is located on the front left bottom of the exte-
rior casing of the water heater. The FV sensor is protected
from shock and contaminants by a robust plastic cover. The
function of the FV sensor is to detect the presence of flam-
mable vapours before they enter the combustion chamber
and ignite. If the FV sensor detects the presence of flam-
mable vapours while the water heater is operating, the gas
control will switch to lock-out mode and the water heater
will shut down. If the water heater is not operating when the
flammable vapours are detected, the control will switch to
lock-out mode and prevent the water heater from lighting.

After a flammable vapour incident has occurred and the flam-
mable vapours have dissipated, the FV sensor is designed
to automatically reset itself. The Intelli-Vent

gas control

however, will have gone into lock-out mode and will need to
be manually reset. An EnerCare qualified service technician
must be called to determine if flammable vapours entered
the combustion chamber and ignited. In most instances,
there will not have been ignition of flammable vapours inside
the combustion chamber because the FV sensor will have
detected these vapours and shut down the water heater. In
this case, the Intelli-Vent

gas control can be reset and the

water heater may resume normal operation. On the other
hand, if the flammable vapours ignited inside the combus-
tion chamber, the water heater may need to be replaced. The
EnerCare technician will be able to determine whether or not
the water heater needs to be replaced based on the amount
of flammable vapours that entered the combustion chamber
and the damage to the water heater from the resulting fire.

Condensation

As moisture from the products of combustion comes into
contact with the cold surface of the inner tank, it may con-
dense. This situation will usually occur:

1) When the water heater is filled with cold water for the first

time.

2) If the water heater has been undersized.

3) When large amounts of hot water are drawn from the

water heater in a short period of time and the refill water
is very cold.

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

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 indi-

cates proper gas combustion. A yellow tipped flame indicates

poor combustion. If so, with a vacuum cleaner, remove any

dust, lint, and dirt accumulation on or around the combus-

tion chamber. If the poor combustion persists and there is

no lint around the water heater call EnerCare Home Services

at 1-866-554-5591. This service call may be at the expenses

of the consumer if lint is blocking the flame arrestor plate.
