Exhaust gases may contain carbon monoxide, a colorless and poisonous gas. Warning FUEL USE This heater is designed for use with propane (LP gas) only. Do not attempt to use gasoline as fuel since fire or explosions may result. Use this heater only with gas regulator part number 88301-T supplied with the heater. Operation with other regulators voids all warranties and may result in fire, explosion, or damage to the heater. Warning ELECTRICAL Heater must be grounded through ground screw supplied. Do not use the fuel line as an electrical conductor or ground connections. Use of the fuel line as electrical or ground conductor may result in fire or explosion. Before performing maintenance or inspection (except operating tests), disconnect the power source. Do not operate the heater with the covers off. The tilt switch is a safety device that stops heater operation in case the vehicle overturns. Do not remove this switch or defeat its purpose. © CAUTION Do not operate the heater at less than 11volts. Propane flow to the burner head is constant, but blower motor speed and combustion airflow vary directly with voltage. Operation on low voltage will produce poor burning, smoke, and unburned fuel mixtures. 1 HITTER Table of Contents Section One_3 Introduction and Description_3 Description _3 Section Two _4 INSTALLATION INSTRUCTIONS_4 Pre-Installation Inspection_4 Location and Mounting_4 Electrical Requirements (FIG.1)_6 Fuel Requirements (FIG.2)_6 Exhaust and Combustion Air Requirements (FIG.3)_7 Heater Mounting Dimensions (FIG.6)_8 Fuel Connections_9 Electrical Connections_10 Section Three_12 OPERATION_12 Controls and Indicators_12 Theory of Operation_13 Starting _14 Section Four__15 TROUBLESHOOTING and DIAGNOSTICS_15 Fault Codes_15 Troubleshooting_16 Burner Head Maintenance_16 Preseason Maintenance, Annual Service_17 Section Five_18 PARTS LIST_18 Installation Hardware _18 Case and Heat Exchanger_19 Fuel, Ignition, and Electronic Control System_20 Blower and Motor Assembly_21 Comfort Control and Remote Harness_22 Section Six_23 OPTIONS and ACCESSORIES_23 Remote Calibrated Thermostat Installation_24 External Diagnostic Light Installation_25 Hunter Mfg. 1999 2 Section One HITTER Introduction and Description This manual contains installation, operation, maintenance, and repair instructions for Model PH-20-30A Heaters manufactured by Hunter Manufacturing Company, Solon, Ohio. Description 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).
