Dyna Glo HA18R Grab N Go XL 18,000 BTU Portable Radiant Propane Heater

Always keep the heater area clear and free from combustible materials, gasoline and other flammable vapors and liquids. Keep the vent areas (slots in the bottom and the top at the front of heater) clear at all times so combustion air and ventilation is not obstructed. Visually inspect the pilot flame and burner periodically during use so combustion air and ventilation is not obstructed. The pilot flame should be blue in color (not yellow) and will extend beyond the thermocouple. The flame will surround the thermocouple just below the tip, see Figure 5. A slight yellow flame may occur where the pilot flame and main burner flame meet. The burner(s) should be bright orange (with a slight blue color around the border, a red-orange haze that is visible on the burner is acceptable) and without a noticeable flame. A blue flame that rolls out at the top indicates an accumulation of dust, lint or spider webs inside the main burner assembly. If the pilot is yellow or the burner has a noticeable flame, cleaning may be required. Use the following procedure to inspect main burner assembly. It is necessary to periodically check the burner(s) orifice and burner venturi tube to make sure they are clear of insects/nests or spider webs that may accumulate over time. It is strongly recommended that these maintenance instructions be performed annually. A clogged tube can lead to a fire.

1. Allow heater to thoroughly cool before performing any maintenance.

2. Remove disposable 1 lb. cylinder(s) from heater or turn OFF gas supply at remote cylinder valve, and disconnect hose from heater.

3. Remove back panel by removing the top three screws, lower two rear screws and two screws behind the doors of the 18K.

4. Inspect interior of casing assembly for accumulation of dust, lint or spider webs. If necessary, clean interior of casing assembly with a vacuum cleaner or apply air pressure. Do not damage any components within casing assembly when you are cleaning.

5. Inspect and clean main burner orifice located at bottom of burner venturi tube by using a vacuum or apply air pressure at orifice opening.

6. Inspect and clean pilot (mounted to bracket) by using a vacuum or apply air pressure through the holes in the pilot indicated by the arrows in Figure 5. WARNING: Never use needles, wires, or similar cylindrical objects to clean the pilot to avoid damaging the calibrated orifice that controls the gas flow.

7. Apply air pressure into burner assembly to remove dust, lint or spider webs.

8. Reinstall back panel.
