2. PLANNING

2.1 I
NSTALLATION ZONES
The FIN-180P can be installed in climatic zones 1 to 4 as defined by the Department of Energy (refer to
Appendix A for the map), whether as a stand alone unit or connected to the ducting of an AHU. Installation
in any other climatic zone may cause damage to the house.
2.2 I
NSTALLATION TYPES
Always use insulated ducting of a minimum R-4 insulation factor.
2.2.1 S A
TAND LONE
The installer shall ensure that, if necessary, an in-line heater sized according to required airflow and outside
design heating temperature from Manual J or ASHRAE table is installed to avoid condensation on
uninsulated duct distribution systems within the house or surfaces near the distribution register. The in-line
heater shall have an integrated airflow sensor and an over temperature sensor to prevent heating in no-flow
or low-flow conditions.
When deciding if a preheater is required and
whether it should be installed BEFORE or
AFTER the supply fan, consider the following:
• This supply fan's minimum operating
temperature is 14°F.
• The minimum distance between the
preheater and the supply fan is 12 inches.
• The temperature distributed in the ducting
should not be below 55°F.
2.2.2 I
NSTALLATION WITH AN
The installer shall ensure that, if necessary, an in-line heater sized according to required airflow and outside
design heating temperature from Manual J or ASHRAE table is installed to ensure that the air delivered to
the AHU is never below the minimum temperature allowed by the manufacturer (generally 55°F). The in-line
heater shall have an integrated airflow sensor and an over temperature sensor to prevent heating in no-flow
or low-flow conditions.
When deciding if a preheater is required and whether it should be installed BEFORE or AFTER the supply
fan, consider the following:
• This supply fan's minimum operating temperature is 14°F.
• The minimum distance between the preheater and
the supply fan is 12 inches.
• The temperature distributed in the ducting
should not be below 55°F, unless the
AHU blower is always running when
the supply fan runs. Refer to
section 5.2 for wiring
configurations.
