norMaL operating sounDs oF
gas appLiances
IIt 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 ap-
pliance. Listed below are some examples. All are
normal
operating sounds
and should not be considered as defects
in your appliance.
Fan:
Masport gas appliances use high tech fans 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 de-
crease in volume depending on the speed setting of your fan
speed switch.
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. Therefore, 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.
Fan 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 operation of a gas regu
-
lator or valve.
unit Body/Firebox:
Different types and thicknesses of steel will expand and con-
tract at different rates resulting in some "cracking" and "ticking"
sounds will be heard throughout the cycling process.
operating instructions
aeration aDJustMent
The burner aeration is factory set but may need adjusting due
to either the local gas supply or altitude.
F43-NG Natural Gas: 1/4" open
F43-LP Propane:
Fully open (rear) and
fully open (front)
F28-NG Natural Gas 1/8" open
F28-LP Propane
3/8" open
The aeration adjustment gears are located on the right side
of the burner box and can be accessed from the side or from
the front when the louvers are removed.
To adjust the aeration: use the allen key to turn the turning
gear which will adjust the air shutter. Open the air shutter for
a blue flame or close it for a yellower flame. This adjustment
is performed by a qualified installer. The factory setting should
be sufficient for most installations.
Clockwise to open,
counter-clockwise to close.
caution: carbon will be produced if the air shutter is
closed too much.
Note: Any damage due to carboning resulting from
improperly setting the aeration controls is NOT
covered under warranty.
