Notice: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the

heater and burn causing brief patches of orange flame.

Figure 24 shows a correct burner flame pat-

tern. Figure 25 shows an incorrect burner

flame pattern. The incorrect burner flame

pattern shows yellow tipping of the flame. It

also shows the flame higher than 1/2 the heat

shield height.

If burner flame pattern is incorrect, as shown

in Figure 25

• turn heater off (see To Turn Off Gas to Ap-

pliance, page 17 or 18)

• see Troubleshooting pages 20 through 24.

WARNING: Turn off heater and let cool before servicing. Only a

qualified service person should service and repair heater.

CAUTION: You must keep control areas, burner, and circulating

air passageways of heater clean. Inspect these areas of heater before

each use. Have heater inspected yearly by a qualified service techni-

cian. Heater may need more frequent cleaning due to excessive lint

from carpeting, bedding material, pet hair, etc.

CAUTION: Never use a wire, needle, or similar object to clean

ODS/pilot. This can damage ODS/pilot unit.

Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.

To troubleshoot the pilot light issue on a Procom MNSD300HGA:

1. Check Gas Supply – Ensure the equipment shutoff valve is fully open.
2. Follow Lighting Instructions – Turn the control knob to OFF, wait five minutes, then try lighting the pilot again by pressing the ignitor button.
3. Manual Lighting – If the ignitor does not work, light the pilot with a match following the Manual Lighting Procedure (page 18).
4. Hold Control Knob – After lighting, keep the control knob pressed for 30 seconds.
5. Check Gas Pressure – If the pilot does not stay lit, gas pressure may be too low. Contact your gas supplier.
6. Consult Troubleshooting Guide – Refer to pages 20-24 for additional troubleshooting steps.
7. Seek Professional Help – If the issue persists, contact a qualified service technician or gas supplier for repairs.
