Start with the heater’s rating plate and owner’s manual. Dyna-Glo’s reviewed product listings identify fuel-specific models and state that conversion is not permitted; never use instructions or parts intended for a different fuel or model. Manufacturer product information
Before troubleshooting: identify the heater and fuel
Find the complete model number on the heater’s rating plate and confirm the fuel type. Match every check, cleaning direction, and replacement part to that model’s manual. The manufacturer’s listings include natural-gas-only and propane-only units; they do not establish that every Dyna-Glo wall heater has the same controls or repair procedure. Fuel conversion is not permitted on the reviewed models. Dyna-Glo product listings
The manufacturer also warns on the reviewed product pages that operation above 4,500 feet could cause pilot outage. This notice applies to those listed models, not necessarily every heater in the product line. If your home is at that elevation, consult your own manual or contact the manufacturer.

Pilot lights, then goes out when you release the knob

Pilot stays lit, but the burner does not start
The manual identifies a thermostat setting that is too low, a clogged or undersized burner orifice, and low inlet pressure as possible causes. Owner-manual troubleshooting guidance

Heater shuts off during use
If the manual indicates that the ODS is operating, it lists insufficient fresh air, low line pressure, or a partially clogged ODS/pilot as possible causes. The ODS is a safety device; do not bypass or disable it. Owner-manual troubleshooting guidance
- Address ventilation: Open a window and/or door as the manual directs.
- Consider pressure: If the problem continues or low line pressure is suspected, contact the local gas supplier.
- Check pilot care instructions: Follow the cleaning directions in the care-and-maintenance section of your specific manual. If cleaning or repair is beyond those instructions, get qualified service.
Unusual odor or white powder residue
Odors can come from vapors produced by products such as paint, hairspray, or glue. The manual advises ventilating and stopping odor-producing products while the heater runs. A gas odor may indicate a leak or low fuel; follow the manual’s warning and leak-checking directions, or contact the gas supplier. Treat a suspected gas leak as a safety issue, not a routine troubleshooting task. Owner-manual odor guidance
