INSTRUCTIONS FOR SAFE LIGHTING, OPERATION AND SHUTDOWN WHEN CONNECTING HEATER TO

DISPOSABLE CYLINDER:

Always connect the heater only to 16.4 oz. (1lb.) disposable propane cylinders that mate with a No. 600 Valve connection. The propane cylinder must be constructed and marked in accordance with the specifications for LP-gas cylinders of the U.S. Department of Transportation (DOT).

Make certain Control Knob (Figure 4) is in OFF position.

Screw 1 lb. disposable propane cylinder HAND TIGHT clockwise into regulator inlet. Make sure cylinder is ALWAYS in an upward position. Take care not to cross thread.

Before each use look through opening at back of heater (Figure 3) to check connection by wetting with soap and water solution to be sure there are no leaks. Never check for leaks with a match.

DO NOT USE HEATER if bubbles form from the soap solution, if you smell gas, or if there are any other leaks in your propane system.

Depress completely and turn control knob coun- terclockwise to PILOT position and hold for 15-30 seconds allowing gas to flow to the pilot. Keeping the control knob depressed, turn from the PILOT to the OFF position and immediately back to the PILOT position to utilize spark igniter. Repeat the PILOT-OFF-PILOT sequence until the pilot lights.

Continue to depress the control knob at the PILOT position for 15-30 seconds to activate the Pilot Light Safety System.

NOTE: If the spark igniter fails to light the pilot, turn knob to OFF, allow at least 2 minutes for gas to dissipate and light with a match.

Release control knob after the pilot is lit and IMMEDIATELY turn to HIGH position to light heater.

NOTE: Within a few minutes, the ceramic tile will develop a steady bright orange glow except for a 1/4’’ border along its outside edges. When lit the first time the top of the reflector will discolor to a bluish-brown.

Adjust heat output by depressing control knob slightly and turning to LOW or HIGH position. To shut off heater, push down control knob and turn clockwise to OFF position.

Disposable cylinders must be disconnected when the heater is not in use.

TROUBLESHOOTING INFORMATION

Spark Igniter does not spark. Contact factory.

Spark igniter sparks but does not light pilot.

1.Pilot is clogged-cleaning is required - see page 2.

2.New outdoor bulk tank being used, but gas not immediately flowing-purge (let air out of) new tank for about 10 seconds. Repeat process. We strongly recommend taking tank back to dealer for purging.

3.Propane not getting to heater-if using

disposable cylinder check connection, or if using hose to outside tank check connections and make sure tank valve is open.

Pilot does not stay lit.

1.Control knob not depressed long enough-try again.

2.Pilot flame not wrapping around thermocouple or yellow in color-clean pilot-see page 2.

3.Pilot assembly defective-contact factory.

Burner does not light or blue flame appears at top of ceramic tile.

Orifice is blocked. Clean orifice-see page 2.

Heater operates but shuts off on its own.

1.Heater exposed to draft-move heater. Also, remember heater is for indoor use only. Pilot will go out when exposed to even minimal wind velocity.

2.Pilot is clogged-cleaning required-see page 2.

3.Not enough ventilation-make certain room has minimum open window or roof vent area of 8 square inches (example 2’’ x 4’’).

4.Heater at too high an altitude (over 6,500 feet). Turn to OFF. Wait several minutes, attempt to relight.
