Filters; Burners; Induced Draft And Circulatorb; Condensate Trap And Drain System - Goodman *CVC96 Installation Instructions Manual

• Flue pipe system. Check for blockage and/or leakage. Check the outside termination and the connections at and internal
to the furnace.
• Heat exchanger. Check for corrosion and/or buildup within the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame, and flame sense.
• Drainage system. Check for blockage and/or leakage. Check hose connections at and internal to furnace.
• Wiring. Check electrical connections for tightness and/or corrosion. Check wires for damage.

ILTER AINTENANCE
Improper filter maintenance is the most common cause of inad-
equate heating or cooling performance. Filters should be cleaned
(permanent) or replaced (disposable) every two months or as re-
quired. When replacing a filter, it must be replaced with a filter of
the same type and size.
F R
ILTER EMOVAL
Depending on the installation, differing filter arrangements can be applied. Filters can be installed in either the central return
register or a side panel external filter rack (upflow only). A media air filter or electronic air cleaner can be used as an alternate filter.
Follow the filter sizes given in the Recommended Minimum Filter size table to ensure proper unit performance.
To remove filters from an external filter rack in an upright upflow installation, follow the directions provided with external filter rack
kit.
H U F R
ORIZONTAL NIT ILTER EMOVAL
Filters in horizontal installations are located in the central return register or the ductwork near the furnace.
To remove:
1. Turn OFF electrical power to furnace.
2. Remove filter(s) from the central return register or ductwork.
3. Replace filter(s) by reversing the procedure for removal.
4. Turn ON electrical power to furnace.

Follow the manufacturer's directions for service.

URNERS
Visually inspect the burner flames periodically during the heating season. Turn on the furnace at the thermostat and allow several
minutes for flames to stabilize, since any dislodged dust will alter the flames normal appearance. Flames should be stable, quiet,
soft, and blue (dust may cause orange tips but they must not be yellow). They should extend directly outward from the burners
without curling, floating, or lifting off. Flames must not impinge on the sides of the heat exchanger firing tubes.

NDUCED RAFT AND IRCULATOR
The bearings in the induced draft blower and circulator blower motors are permanently lubricated by the manufacturer. No further
lubrication is required. Check motor windings for accumulation of dust which may cause overheating. Clean as necessary.
C T D
ONDENSATE RAP AND RAIN
Annually inspect the drain tubes, drain trap, and field-supplied drain line for proper condensate drainage. Check drain system for
hose connection tightness, blockage, and leaks. Clean or repair as necessary.

LAME ENSOR UALIFIED
Under some conditions, the fuel or air supply can create a nearly invisible coating on the flame sensor. This coating acts as an
insulator causing a drop in the flame sense signal. If the flame sense signal drops too low the furnace will not sense flame and will
lock out. The flame sensor should be carefully cleaned by a qualified servicer using emery cloth or steel wool. Following cleaning, the
flame sense signal should be as indicated in the Specifications Sheet.
