LIGHTING AND OPERATING

INSTRUCTIONS

Continued

IMPORTANT: When not in use, the gas must be turned off at the propane/LP gas supply cylinder. When the propane/LP gas supply cylinder is not disconnected from the heater, the heater and the cylinder must be stored outdoors, in a well ven- tilated space, out of reach of children, and must not be stored in a building, garage or any other enclosed area.

IMPORTANT: Indoor storage of the heater is permissible only if the cylinder is disconnected and removed from the heater. Cylinders must be stored outdoors out of the reach of children and must not be stored in a building, garage or any other enclosed area.

CLEANING AND

MAINTENANCE

WARNING: Turn off heater and let cool before cleaning.

CAUTION: You must keep control areas, burner, and circu- lating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualiﬁed service person.

CAUTION: You must check and keep burner/venturi tubes clean of insect and insect nest.A clogged tube can lead to a ﬁre.

WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

ODS/PILOT AND BURNER

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

BURNER PILOT AIR INLET

The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning ﬂame. Keep these holes clear of dust, dirt, and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a qualiﬁed service person.

We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If using com- pressed air in a can, please follow the directions on the can. If you don't follow directions on the can, you could damage the pilot assembly.

Always keep the heater area clear and free from combustible materials, gasoline and other ﬂam- mable 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 periodi- cally during use. The pilot ﬂame should be blue in color (not yellow) and will extend beyond the thermocouple. The ﬂame will surround the ther- mocouple just below the tip. See Figure 4. A slight yellow ﬂame may occur where the pilot ﬂame and main burner ﬂame meet. The burner should be bright orange (with a slight 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.
