• Annually inspect the return-air connection to ensure
that it is physically sound and is still sealed to the
casing of the unit. Also inspect the unit, ductwork, and
vent system for signs of physical deterioration.
• Always replace the doors on the unit after servicing.
Do not operate the unit without all doors and covers
in place. Avoid operating the unit when windows and
doors are open.
Regular Cleaning
• Remove any leaves and grass clippings from the
outdoor coil. IMPORTANT: Be careful not to damage
the aluminum fi ns.
• Check for and remove any obstructions such as twigs,
sticks, etc.
• Clean the blower compartment regularly during the
heating and cooling seasons to remove any dust
that may have accumulated in the compartment or on
the blower and motor. Buildup of dust on the blower
and motor can create excessive loads on the motor
resulting in higher than normal operating temperatures
and possible shortened service life.
Air Filters
WARNING:
Never operate the unit without a fi lter in the
return air system. Dust and lint in the return
air can build up on the internal components,
resulting in loss of efficiency, equipment
damage, and possible fi re risk.
R6GP & R6GN Series units are factory equipped with
pleated 2 inch disposable fi lters. The fi lters should be
checked periodically and replaced (or cleaned) when
necessary with fi lters of the same dimensional size.
Replace using disposable fi lters with a minimum airfl ow
rating of 500 FPM or permanent fi lters only.
IMPORTANT NOTES:
• The fi lter rack in 6, 7.5 & 10 ton units are fi eld
adjustable to accommodate 1” permanent fi lters.
DO NOT use 1” disposable fi lters in these units.
• Always replace the fi lter access panels after
changing or cleaning the fi lters. DO NOT operate
unit without the fi lter access panels in place.
• It is very important to replace or clean the fi lter(s)
installed in the return air duct of this system. A
clogged fi lter could cause airfl ow related problems
and reduce the overall effi ciency of your unit.
Always replace disposable fi lter(s) installed in
your system only with the same size dimensional
fi lters that are being replaced.
• Filters must be ULC approved or equivalent for
use in Canada.
Motor Lubrication
The motors for the circulating air blower, outdoor fan, and
combustion blower are pre-lubricated and sealed by the
manufacturer. No further oiling is required for the life of
this product.
Burner Maintenance
CAUTION:
Some components in the burner vestibule are
at high temperatures while the burners are
operating. Use caution to avoid personal injury.
Check the burner fl ames at the start of every heating
season. Set the thermostat above the room temperature.
Remove the control access panel to the unit and visually
inspect the burner assembly to make sure that the fl ame
is drawn directly into the center of the heat exchanger tube
(See Figure 2). In a properly adjusted burner assembly,
the fl ame bends up and to the left at the end of the heat
exchanger tube, and the end of the fl ame will be out of
sight around the bend. The fl ame color should be blue,
however some light yellow streaks may occur on the outer
portions of the fl ame.
TROUBLESHOOTING
Before you call a Technician, check the following:
• Check the thermostat setting. Make sure the system
mode and temperature settings are correct.
• Check the electrical panel for tripped circuit breakers.
• Check the fi lters for dust accumulation.
• Check the unit and make sure it is clean and not
covered with grass or leaves.
• If the items above don’t resolve your problems, then
call your nearest service technician.
