When the furnace is heating, the temperature of the return
air entering the furnace must be between 55°F and 100°F.

Filter Sizing Chart
^ Larger filters may be used, filters may also be centrally located
Change filters before occupants take ownership of a new home.
Filters must be used with this furnace. Discuss filter
maintenance with the building owner. Filters do not ship
with this furnace, but must be provided, sized and installed
externally by the installer. Filters must comply with UL900
or CAN/ULCS111 standards. Damage or repairs due to the
installation of the furnace without filters are not covered
under the warranty.
On upflow units, guide dimples locate the side return cutout
locations. Use a straight edge to scribe lines connecting
the dimples. Cut out the opening on these lines. NOTE: An
undersized opening will cause reduced airflow.
Refer to the Filter Sizing Chart to determine filter area
requirements.
Consider installing an air cleaner with deep-pleated media
filter at the time of furnace installation. A deep-pleated filter
with a MERV rating of 8 (minimum) will often provide better
filtration to protect equipment and the air distribution system
than a standard 1” filter and often has lower static pressure
loss than a 1” filter. Also a deep-pleated filter will typically
require less frequent replacement intervals. Avoid using
highly restrictive 1” filters which produce static pressure loss
greater than .25” W.C. In some installations the minimum
filter size required (consult filter sizing chart on page 34) will
not lend itself to a filter installation on the side of the furnace.
The installation of a centrally installed air cleaner cabinet or
a return duct filter installation may offer more practicality.
Clean Comfort™ brand MERV 11 air cleaners have 5¼”
media filters and are available in the following configurations.
Consult your distributor for information on our complete line
of IAQ Clean Comfort™ products.
Upright Installations
Depending on the installation and/or customer preference,
differing filter arrangements can be applied. Filters can be
installed in the central return register or a side panel external
filter rack kit (upflows). As an alternative a media air filter or
electronic air cleaner can be used as the requested filter.
Figures 38 & 39 show possible filter locations.
Horizontal Installations
Filters must be installed in either the central return register
or in the return air duct work.
STARTUP PROCEDURE & ADJUSTMENT
Furnace must have a 115 VAC power supply properly
connected and grounded. Proper polarity must be maintained
for correct operation. In addition to the following start-up and
adjustment items, refer to further information in
Operational
Checks
section.
Furnace Cabinet
Check that all furnace cabinet sealing components are in
place (plugs, grommets, gaskets).
NOTE: If the bottom panel has not been removed for a
return duct connection, all performations must be sealed
with duct sealant compound or other suitable method to
prevent air leakage. For optimal performance verify that all
door gaskets are properly in place and replace as needed to
prevent air leakage.
Drain Trap Priming
The drain trap must be primed prior to furnace startup.
To prime, fill both sides of the drain trap with water. This
ensures proper furnace drainage upon startup and prohibits
the possibility of flue gases escaping through the drain
system.
Furnace Operation
Purge gas lines of air prior to startup. Be sure not purge
lines into an enclosed burner compartment.
Check for leaks using an approved chloride-free soap and
water solution, an electronic combustible gas detector, or
other approved method. Verify that all required kits (propane
gas, high altitude, etc.) have been appropriately installed.
Furnace Startup
1. Close the manual gas shutoff valve external to the
furnace.
2. Turn off the electrical power to the furnace.
3. Set the room thermostat to the lowest possible
setting.
4. Remove the burner compartment door.
NOTE: This furnace is equipped with an ignition device
which automatically lights the burner. Do not try to light the
burner by hand.
