DUE TO HIGH TEMPERATURES, THE HEATER SHOULD BE LOCATED OUT OF
TRAFFIC AND AWAY FROM COMBUSTIBLE MATERIALS.
Children and adults should be alerted to the hazard of high surface temperature and should stay away
to avoid burns or clothing ignition.
Young children should be carefully supervised when they are near the heater.
Do not place clothing or other flammable material on or near the heater.
Any safety screen or guard removed for servicing the heater must be replaced prior to operating the
heater.
The heater should be inspected before each use. Frequent cleaning may be required.
The control compartments, burners and circulating air passageways of the heater must be kept clean.
H E AT E R M A I N T E N A N C E I N S T R U C T I O N S
Do not obstruct the flow of combustion and ventilation air.
Keep vent slots clean.
Make a periodic visual check of pilot and burner flame to
ensure proper operation. The pilot flame will extend beyond
the thermocouple wrapping around it just under the tip. If
yellow in color instead of blue, cleaning may be required.
The burner should have a bright orange glow with a slight
blue color around the border without any noticeable flame.
A blue flame at the top of the ceramic tile is indicated
excessive dust, dirt or spider webs inside the steel casing
and/or reflector assembly, and means that cleaning is
probably necessary.
When cleaning heater (figure 1):
1. Disconnect disposable 1lb. cylinder (if using remote bulk
tank turn off gas supply at remote cylinder valve, then
disconnect hose from heater.)
2. Gently bend wire guard to remove wire guard prongs (a)
from mounting holes in steel casing, freeing wire guard.
3. Insert a flat bladed screwdriver between the top (hori-
zontal) edge of the reflector assembly (B) and the steel
casing and push down until the steel tab (C) on the top
edge of the reflector assembly releases from the steel
casing.
Gas-Fired Portable Unvented Heater for
Recreational and Commercial Use
Model No.: 7500
Input (BTU/hr.): 8000 Maximum,
4000 Minimum
Gas Type: Propane
Manifold Pressure: 11’’ W.C.
4. Ease reflector assembly away from steel casing.
5. Inspect casing interior components for spider webs
as well as dust or dirt.
a. If necessary use a vacuum cleaner or
compressed air to clean:
- Steel casing interior.
- Burner orifice at orifice opening (D)
- Pilot (E) through the holes in the pilot
indicate by arrows in Figure 2. Never
touch drilled holes in pilot, as they are
extremely delicate. Insertion of pins,
wire, etc. is likely to disturb proper
gas flow.
b. If necessary, use compressed air to clean
venturi tube (F) and ceramic tile (G).
6. Ease reflector assembly back into steel casing.
Pushing down on top edge with flat bladed screw
driver, insert tab in hole in steel casing.
7. Gently bend wire guard and insert prongs into
mounting holes in steel casing.
Remember to check and clean the burner orifice
and venturi tube on a regular basis to eliminate
inserts, insect nests and spider webs. A clogged
tube can lead to a fire.
Keep Heater area clear and free from combustible materi-
als, gasoline and other flammable vapors and liquids.
Minimum Distance To Combustibles: Top 30’’, Front 24’’,
Sides 6’’, Rear 0’’
Do not store or use gasoline or other flammable vapors
and liquids in the vicinity of this or any other appliance.
