GENERAL INFORMATION:

A periodic sniff test around the heater or at the heater’s joints; i.e. hose, connections, etc., is a good safety practice under any conditions. If you smell even a small amount of gas, CONTACT YOUR FUEL GAS SUPPLIER IMMEDIATELY. DO NOT WAIT!

GENERAL INFORMATION:

propane cylinder. Do not use if head of cylinder is damaged, punctured or deteriorated.

ALWAYS ATTACH OR DETACH CYLINDER OUTDOORS AWAY FROM FLAMES, OTHER IGNITION SOURCES, AND ONLY WHEN HEATER IS COOL TO TOUCH. NEVER SMOKE WHEN ATTACHING OR REMOVING PROPANE CYLINDER OR MAKING REMOTE CONNEC- TIONS!

This heater is safe for indoor use in small recreational enclosures having means for providing combustion air and ventilation, such as enclosed porches, cabins, fishing huts, trailers, tent trailers, tents, truck caps and vans.

It may be used for emergency indoor heating when connected to a disposable 1-lb. propane cylinder and for indoor use in commercial enclosures, having means for providing combustion air and ventilation, such as construction trailers or temporary work enclosures.

Note: The heater can be used outdoors, but may experi- ence nuisance shutoffs due to certain wind conditions.

When the heater is cold or at room temperature, it will

 

take a few minutes for the burner tile to turn bright or-

 

ange. This is normal and the heater is working properly.

 

If burner tile is visibly flaming, turn heater off and call a

 

qualified service technician.

When the unit is lit, there should be about a quarter

 

inch (1/4”) border around the tile that will not turn

 

bright orange. This is normal.

When operating the heater for the first time, the top

 

area of the reflector may discolor. This is also normal

 

and is no reason for concern.

The protective grill on the front of this heater is coated

 

with a special high-temperature resistant paint. When

 

the heater is used for the first time, the grill may give

 

off noticeable smoke or fumes. This is normal and will

 

not occur during subsequent uses. The fumes are not

 

harmful.

When operating the heater at altitudes over 7,000 FT.

 

above sea level, the unit may not burn as bright as in

 

lower altitudes. This is normal. At higher altitudes, the

 

heater may shut-off. If this happens, provide fresh air,

 

wait 5 minutes and re-light. Due to local atmospheric

 

conditions heater may not re-light.

Operating time will vary depending on the heater set-

 

ting and the supply cylinder size. Up to 3 to 6 hours

 

on a 1 lb. cylinder. Up to 48 to 110 hours on a 20 lb.

 

cylinder (based on “HI” and “LO” settings).

When moving heater when lit or bumping heater setting

 

it down, tip over switch may shut off heater. If this hap-

 

pens, re-light.

Use only LP-gas cylinders marked in accordance with the U.S. Dept. of Trans- portation (DOT).

Use only 16.4 oz.

(1 lb.) disposable cylinders that mate with No. 600 valve connection.

Heater and attached cylinder must be in an upright position during operation.

Make sure four-po- sition Control Knob is in “OFF” position; see Figure 1.

Swivel regulator out- ward for easy tank installation. Screw 1 lb. disposable LP-gas supply cylinder clock- wise (from bottom) into portable heater until hand-tight; see

Figure 2.

Check cylinder con- nection for leaks with soapy water at the threaded con- nection under the domed plastic cover where the cylinder screws into the regu- lator. SEE WARNING! ON DOMED PLASTIC COVER.
