1. A heating and cooling contractor preparing for the Fort Wayne/Allen
County licensing examination should understand that the
examination is administered as an open-book examination with a
four-hour time limit. Which combination of reference codes has
historically been identified for the Fort Wayne HVAC examination
materials?
A. 2018 International Mechanical Code, 2018 International Fuel Gas Code,
and 2017 National Electrical Code
B. 2015 International Mechanical Code, 2015 International Fuel Gas Code,
and 2014 National Electrical Code
C. 2012 International Mechanical Code, 2012 International Fuel Gas Code,
and 2011 National Electrical Code
D. 2021 International Mechanical Code, 2021 International Fuel Gas Code,
and 2020 National Electrical Code
B. 2015 International Mechanical Code, 2015 International Fuel Gas
Code, and 2014 National Electrical Code
,The Fort Wayne Area Plumbing Heating Cooling Contractors Association
identifies the 2015 International Mechanical Code, 2015 International
Fuel Gas Code, and 2014 National Electrical Code among the
examination reference materials, while Allen County states that its trade
examinations are open book with a four-hour time limit.
2. An HVAC contractor is preparing to replace an existing residential
furnace in Fort Wayne. Which principle should govern the
contractor's approach to installation?
A. Existing equipment may be replaced without regard to applicable
mechanical requirements because replacement work is automatically
exempt
B. The contractor should install the equipment according to applicable
mechanical, fuel-gas, electrical, manufacturer, and permitting
requirements
C. Only the electrical portion of the replacement is subject to code
because heating equipment is classified solely as an appliance
D. The contractor may disregard combustion-air requirements when
replacing an existing furnace with a newer model
B. The contractor should install the equipment according to applicable
mechanical, fuel-gas, electrical, manufacturer, and permitting
requirements
HVAC replacement work remains subject to applicable safety and
installation requirements, including mechanical, fuel-gas, electrical,
manufacturer, and local permitting provisions.
, 3. A gas furnace is installed in a mechanical room that does not have
adequate combustion air. What is the primary safety concern?
A. Reduced refrigerant pressure
B. Incomplete combustion and possible production of carbon monoxide
C. Excessive condenser subcooling
D. Increased electrical resistance in the thermostat circuit
B. Incomplete combustion and possible production of carbon monoxide
Insufficient combustion air can cause incomplete combustion, producing
carbon monoxide and potentially creating an unsafe operating condition
for occupants and equipment.
4. A contractor is sizing a gas vent for a furnace and must determine
whether the venting arrangement is acceptable. Which factor is
most directly relevant to proper vent sizing?
A. The color of the furnace cabinet
B. Appliance input, vent type, configuration, and applicable venting
requirements
C. The thermostat's manufacturer only
D. The refrigerant type used by the air-conditioning system
B. Appliance input, vent type, configuration, and applicable venting
requirements
Gas venting must be evaluated according to appliance characteristics,
vent construction, configuration, and the applicable fuel-gas and
, mechanical-code requirements rather than unrelated equipment
characteristics.
5. A forced-air furnace is installed in a dwelling. The blower moves
conditioned air through supply ducts and receives return air
through return openings. What is the primary purpose of the
return-air system?
A. To provide combustion air to the burner
B. To return conditioned-space air to the air-handling equipment for
recirculation or treatment
C. To exhaust flue gases outdoors
D. To discharge condensate from the evaporator coil
B. To return conditioned-space air to the air-handling equipment for
recirculation or treatment
The return system transports indoor air back to the furnace or air
handler so that the air can be filtered, heated, cooled, or otherwise
conditioned before being supplied again.
6. A contractor discovers that a furnace's heat exchanger is cracked.
What should be the contractor's primary concern?
A. Increasing the blower speed until the crack closes
B. Preventing combustion products from entering the occupied-air stream
and correcting the unsafe condition
C. Increasing the thermostat differential
D. Adding refrigerant to the cooling circuit
