4.1 Pulea le Panelview

Image 4.1: The control panel features a Piezo Ignition button and a thermostat knob with variable heat settings.

The heater features a simple control panel with a Piezo Ignition button and a thermostat control knob. The thermostat knob allows you to select heat settings from "OFF PILOT" to various heat levels (e.g., 1-5 or High/Medium/Low).

4.2 Initial Startup Procedure

IMPORTANT: For the very first use, or after the heater has been disconnected from the propane supply for an extended period, the initial ignition may take longer than usual. This is normal as air needs to be purged from the gas lines.

1. Ensure the propane supply valve is fully open.
2. Turn the thermostat control knob to the "PILOT" position.
3. Press and hold the thermostat control knob down firmly.
4. While holding the knob down, repeatedly press the Piezo Ignition button until the pilot flame ignites. You may need to hold the knob down for several minutes (up to 10 minutes for the very first startup) to allow gas to reach the pilot.
5. Once the pilot flame is lit, continue to hold the thermostat control knob down for approximately 30-60 seconds to allow the thermocouple to heat up and hold the pilot flame.
6. Release the knob. If the pilot flame extinguishes, repeat steps 3-5.
7. Once the pilot flame is stable, turn the thermostat control knob to your desired heat setting (e.g., 3, 4, 5, or High/Medium/Low). The main burner will ignite.

NOTE: It is recommended to perform the first ignition outdoors or in a well-ventilated area, as a thin oil layer on internal components may burn off, causing a temporary odor or light smoke.

4.3 Fetuunaiga o le Vevela

Rotate the thermostat control knob to adjust the heat output. Higher numbers or "High" settings will provide more heat, while lower numbers or "Low" settings will reduce the heat output. The heater will cycle on and off to maintain the set temperature.

5. Tausiga

Regular maintenance ensures the safe and efficient operation of your ProCom heater. Always disconnect the heater from the propane supply and allow it to cool completely before performing any maintenance.

• Fa'amamaina: Keep the exterior of the heater clean. Use a soft, damp cloth to wipe down surfaces. Do not use abrasive cleaners or solvents. Ensure the air intake and exhaust vents are free from dust and debris.
• Pilot and Burner Inspection: Periodically inspect the pilot and main burner for any obstructions or unusual flame patterns. If the pilot flame appears weak or yellow, or if the main burner flames are not blue, contact a qualified service technician.
• Gas Line Inspection: Regularly check the gas supply line and connections for any signs of wear, damage, or leaks.
• Teuina: If storing the heater for an extended period, disconnect it from the propane supply, clean it thoroughly, and store it in a dry, safe place.
