PRODUCT FEATURES

Efficiency

ADP gas-fired unit heaters and duct furnaces deliver
between 80% and 82% thermal efficiency. This excellent
efficiency sets a new standard when using gas-fired unit
heaters and duct furnaces.

Reliability

ADP heater designs have proven superior for over a
decade and during hundreds of thousands of hours in the
toughest winter climates of North America and under
extreme conditions in laboratory life cycle testing. ADP unit
heaters and duct furnaces have been designed to provide a
long, trouble free service life.

Quality

Every heater undergoes continuous quality checks at all
stages of manufacturing. After assembly, each heater is
test fired and functionally tested to provide final assurance
that it is performing in accordance with ADP’s rigorous
quality standards.

Approvals

All ADP heaters are built in the USA in an ISO 9001:2008
facility. The rating plate of each heater carries the mark
signifying that the heater is design certified by CSA. In
addition, the heater series is listed by the California Energy
Commission (CEC).

Warranty

ADP unit heaters feature a standard 2-year limited
warranty. For FOA, FSA, and SEP Series, the warranty
provides extended coverage on aluminized heat
exchangers for 10 years. For SEP Series, the warranty
provides extended coverage on stainless steel heat
exchangers for 15 years.

Power Exhaust

All heaters have a sealed flue collector and a power
exhaust system which enable conventional vertical venting
or horizontal venting. Power exhaust, when used with
horizontal venting, lowers operating cost because it
reduces stack losses. It also allows the option of not
penetrating the roof, or multiple floors. The versatile power
exhaust (on some models) reduces installation cost further
by allowing the exhaust to be directed upward, left or right,
just by rotating the exhaust assembly.

In Shot Burners

These lightweight aluminized steel burners are
maintenance-free and never require adjustment. The
burner venturi mixes air and gas in the correct proportion
for efficient combustion. The entire burner assembly is
removable as one piece for ease of service.

Tubular Heat Exchangers

Constructed of aluminized steel for superior resistance to
corrosion and oxidation; for additional protection, some
models have an optional stainless steel heat exchanger.
The curving design provides for complete exposure of the
heating surface to the supply air stream. Rounded surfaces
minimize air resistance and permit air to surround all heat
transfer surfaces for excellent heat transfer. Tubular
design means lighter weight and significantly longer service
life due to lower thermal-induced stresses. .

Direct Spark Ignition

In combination with the 24-volt main gas valve with 100%
shutoff for safety, the direct spark ignition control provides
positive, reliable and safe main burner ignition. This
eliminates the need for a pilot light, improving system
efficiency and reliability. A separate flame sensor provides
proof of main burner ignition. If loss of main burner flame
should occur, the control will reinitiate ignition three times
before locking out, thus reducing nuisance service calls.
The unit will reinitiate ignition after the one hour lockout.
The prepurge operation safety removes all gas and flue
products from the system prior to ignition.

Cabinet

Constructed heavy gauge painted steel, each cabinet has a
two-point suspension system for easy installation (larger

and two-fan models have four-point suspensions).

Generous use of inside cabinet insulation keeps the outer
surface temperature low. The wiring junction box is
conveniently located on the side of the cabinet (SEP &
HED only) for easy access and adequate protection.
