Integral Indirect Gas-Fired Heat Module
OPTION
5.7 INSTALL SUPPLY AIR TEMPERATURE SENSOR
The Supply Air temperature sensor is factory-wired to the Integrated Programmable Controller
but the sensor must be installed in the SA ductwork downstream of the gas heat module. The
temperature sensor should be installed between 4 and 6 feet from the unit in the SA ductwork
to control the temperature output of the gas heat module.
The Supply Air temperature sensor is shipped in the low-voltage side of the unit electrical box.
5.8 INSTALL GAS SUPPLY PIPING
5.8.1 Installation of Gas Piping
All components of this or any other gas-fired heating unit must be leak-tested prior to plac-
ing the unit into operation. A soap and water solution or other non-corrosive leak detection
fluid should be used to perform this test. NEVER test for gas leaks with an open flame.
WARNING
When leak testing at pressures equal to or less than 14 inches WC [3.5 kPa], first close the
field-installed shutoff valve to isolate the unit from the gas supply.
WARNING
INSTALLATION
5.6 MODULE INSTALLATION REQUIREMENTS
The heat module is installed on the positive pressure side of the ERV air blower. The air
throughput must be within the CFM range marked on the module rating plate.
Ductwork should be mechanically fastened to the unit. Joints should be sealed with high
temperature silicone caulking or high temperature tape to prevent leakage of circulating air. All
outdoor module duct connections must be weathertight to prevent rain and snow from entering
the ductwork. Support all ductwork securely. DO NOT rely solely on module duct connections
for support. Provide removable access panels in ductwork immediately downstream of the heat
module to allow for inspection of the heat exchanger. These openings should be large enough to
observe smoke or reflected light inside the casing to inspect the heat exchanger for leaks and to
check for hot spots on the heat exchanger due to poor air distribution or insufficient air volume.
Attach covers so as to prevent air leakage. See figure below.
