Hunter Fan PH20-30A User Manual
Page 4
This manual contains installation, operation, maintenance, and repair instructions
for Model PH-20-30A Heaters manufactured by Hunter Manufacturing Company, Solon,
Ohio.
The Falconaire PH20-30A is a 12 VDC Microprocessor Based, Direct Spark
Ignition, thermostatically controlled heater. The control utilizes a microprocessor to
continually and safely, monitor, analyze and control the proper operation of the gas
burner. Value added features such as, combustion blower control, LED diagnostic
output, automatic one hour reset, and multiple ignition tries, highlight the controls
benefits.
Model PH-20-30A is designed for use solely with propane (LP gas) as fuel.
Combustion air is supplied by a single-stage combustion air blower, and fuel flow to the
burner head is controlled by a solenoid valve and a restrictor in the fuel line. Because
the propane enters the burner head as a gas, no carburetor is required. Ignition of the
propane is accomplished with a spark plug-like igniter, which is supplied with high
voltage current from the Electronic Control Module (ECM).

NOTE
All specifications are based on the use of a vapor-withdrawal gas
bottle and gas regulator part number 88301-T. Operation under
other fuel conditions voids all warranties. This regulator provides the
mandatory pressure (11 inches H2O) required by the calibrated
burner head orifice.
