MAINTENANCE: 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. Visually inspect the pilot flame and burner periodically during use. 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 2, below. A slight yellow flame may occur where the pilot flame and main burner flame meet. The burner should be bright orange (with a slight Figure 2 blue color around the border, a red-orange haze that is visible on the ceramic tile is acceptable) and without a noticeable flame. A blue flame that rolls out at the top of the ceramic tile indicates an accumulation of dust, lint or spider webs inside the casing assembly and 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 the casing assembly and main burner assembly. It is necessary to periodically check the burner orifice and burner venturi tube to make sure they are clear of insects/nests or spider webs that may accumulate over time. A clogged tube can lead to a fire. 1 Allow heater to thoroughly cool before performing any maintenance. 2 Remove disposable 1 lb. cylinder from heater or turn OFF gas supply at remote cylinder valve, and disconnect hose from heater. 3 Remove wire guard from front of heater by gently bending to remove from holes in front cover. 4 Remove (1) burner assembly retaining screw from bottom of the heater. 5 Pull burner assembly from front of the heater. 6 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. 7 Inspect and clean main burner orifice (mounted to pilot bracket with jam nut) by using a vacuum or apply air pressure at orifice opening. 8 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 2, at left. WARNING: Never use needles, wires, or similar cylindrical objects to clean the pilot to avoid damaging the calibrated ruby that controls the gas flow. 9 Apply air pressure into ceramic tile of burner assembly and the venturi tube (with cone on end) to remove dust, lint or spider webs. 10 Make sure the burner tile assembly is completely seated against the reflector. 11 Carefully slide burner assembly back into casing assembly making sure to center reflector flange with the casing opening and hold in place while installing burner assembly screw in the bottom of the heater. 12 Install wire guard by gently bending and inserting into the (4) holes in the front cover. Mr. Heater | Portable Buddy 5 Operating Instructions and Owner’s Manual TROUBLESHOOTING INFORMATION: TROUBLESHOOTING INFORMATION: • Spark electrode broken – replace. • Igniter wire may not be attached to spark electrode, ground wire may not be attached to frame - attach. • Igniter wire damaged – replace. • Piezo igniter defective – replace. If Spark electrode produces spark but pilot does not light. CHECK • No gas to heater – install disposable cylinder or connect hose and turn on valve at remote cylinder. • “PILOT” position not properly aligned – turn gas control knob to “PILOT” position and depress. • Pilot is blocked from spider web or dirt – clean pilot, see MAINTENANCE. If Pilot flame does not stay lit when knob is released. CHECK • Control knob in “PILOT” position not completely depressed or held in long enough to purge air from lines. • Pilot flame not surrounding thermocouple – clean pilot, see MAINTENANCE. • Pilot Assembly defective – replace. If Main burner does not ignite. CHECK • Main burner orifice is blocked – clean burner, see MAINTENANCE. If Heater keeps shutting “OFF” during normal operation. CHECK • Pilot is blocked – clean pilot, see MAINTENANCE. • Provide minimum fresh air opening of 9 square inches (example 3” x 3” opening). • Tip over switch activated from bumping heater.
