Normal Operating Sounds of
Gas Appliances
It is possible that you will hear some sounds from
your gas appliance. This is perfectly normal due to
the fact that there are various gauges and types
of steel used within your appliance. Listed below
are some examples. All are normal operating
sounds and should not be considered as defects
in your appliance.
Blower:
Hampton
gas appliances use high tech blowers
®
to push heated air farther into the room. It is not
unusual for the fan to make a "whirring" sound
when ON. This sound will increase or decrease in
volume depending on the speed setting of your fan
speed control.
Burner Tray:
The burner tray is positioned directly under the burner
tube(s) and logs and is made of a different gauge
material from the rest of the firebox and body. There-
fore, the varying thicknesses of steel will expand and
contract at slightly different rates which can cause
"ticking" and "cracking" sounds. You should also be
aware that as there are temperature changes within
the unit these sounds will likely re-occur. Again, this
is normal for steel fireboxes.
Blower Thermodisc:
When this thermally activated switch turns ON it will
create a small "clicking" sound. This is the switch
contacts closing and is normal.
Pilot Flame:
While the pilot flame is on it can make a very slight
"whisper" sound.
Gas Control Valve:
As the gas control valve turns ON and OFF, a dull
clicking sound may be audible, this is normal opera-
tion of a gas regulator or valve.
Unit Body/Firebox:
Different types and thicknesses of steel will ex-
pand and contract at different rates resulting in
some "cracking" and "ticking" sounds will be heard
throughout the cycling process.
Maintenance Instructions
1) Always turn off the valve before cleaning. For
relighting, refer to lighting instructions. Keep the
burner and control compartment clean by brush-
ing and vacuuming at least once a year. When
cleaning the logs, use a soft clean paint brush
as the logs are fragile and easily damaged.

2) Clean glass (never when unit is hot), appliance,
and door with a damp cloth. Never use an
abrasive cleaner.
3) The heater is finished in a porcelain finish or
with a heat resistant paint and should only be
refinished with heat resistant paint (not with wall
paint).
Never use an abrasive cleaner on the porcelain
finish as it may scratch the surface.
4) Make a periodic check of burner for proper posi-
tion and condition. Visually check the flame of
the burner periodically, making sure the flames
are steady; not lifting or floating. If there is a
problem, call a qualified service person.
5) CAUTION: Label all wires prior to disconnection
when servicing controls. Wiring errors can cause
improper and dangerous operation.
6) The appliance and venting system must be
inspected before use, and at least annually, by
a qualified field service person, to ensure that
the flow of combustion and ventilation air is not
obstructed.
During the annual service call, the burners should
be removed from the burner tray and cleaned.
Replace the embers but do not block the pilot.
7) Keep the area near the appliance clear and free
from combustible materials, gasoline, and other
flammable vapours and liquids.
WARNING: CHILDREN AND ADULTS
SHOULD BE ALERTED TO THE HAZ-
ARDS OF HIGH SURFACE TEMPERA-
TURE AND SHOULD STAY AWAY TO
AVOID BURNS OR CLOTHING IGNI-
TION. YOUNG CHILDREN SHOULD
BE CAREFULLY SUPERVISED WHEN
THEY ARE IN THE SAME ROOM AS
THE APPLIANCE.
DO NOT USE THIS APPLIANCE IF
ANY PART HAS BEEN UNDER WA-
TER. IMMEDIATELY CALL A QUALI-
FIED SERVICE TECHNICIAN TO
INSPECT THE APPLIANCE AND TO
REPLACE ANY PART OF CONTROL
SYSTEM AND ANY GAS CONTROL
WHICH HAS BEEN UNDER WATER.
maintenance
CLOTHING OR OTHER FLAMMABLE
MATERIAL SHOULD NOT BE PLACED
ON OR NEAR THE APPLIANCE.
CAUTION: ANY SAFETY SCREEN
OR GUARD REMOVED FOR SER-
VICING AN APPLIANCE MUST BE
REPLACED PRIOR TO OPERATING
THE APPLIANCE.
8) Each time the appliance is lit, it may cause con-
densation and fog the glass. This condensation
and fog is normal and will disappear in a few
minutes as the glass heats up.
Never operate the appliance without the
glass properly secured in place.
9) Periodically check the pilot flames. Correct
flame pattern has three strong blue flames: 1
flowing around the thermopile and 1 around the
thermocouple, and 1 flowing across the rear of
the burner (it does not have to be touching the
burner).
Note: If you have an incorrect flame pattern,
contact your Hampton
®
instructions.

Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact with
the rear of the burner or thermopile.
