Symptom Problem Solution
Heater shuts down while
running.
Heater producing odor.
Propane / L.P. supply may be
inadequate.
High surrounding air temperature
causing thermal limit device to shut
down heater.
Restricted air flow.
Damaged fan.
Excessive dust or debris in
surrounding area.
Gas leak
Heater operating on a 20 lb.
Propane / L.P. cylinder. Insufficient
Propane / L.P. gas will be supplied
by a 20 lb. cylinder resulting in odor
Propane / L.P. supply tank is "freez
-
ing up". Evaporation and consump-
tion rate of propane from supply
tank is to great for the size of the
tank and air temperature
a. Refill tank
b. Provide additional and/or larger
tanks. See "Preparation: Propane
Supply".
This can happen when running heater
in temperatures above 85° F (30° C).
Run heater in cooler temperatures.
Check heater inlet and outlet. Re-
move any obstructions.
Replace fan. See "Maintenance:
Fan".
Clean heater. See "Maintenance".
Check all connections for leaks. Apply
mixture of liquid soap and water to
gas joints. Bubbles forming show a
leak that must be corrected
To obtain correct mixture of
Propane /
L.P. gas and air, use a larger cylinder
size, i.e. 40 lb. (minimum) or 100 lb.
See "Preparation: Propane
Supply".
a. Use a larger supply cylinder size,
i.e. 40 lb. (minimum) or 100 lb.
b. Reduce consumption rate by
operating the heater at LOW
setting temporarily until frost
disappears from the tank
WARNING: HIGH VOLTAGE. NEVER SERVICE SPACE HEATER WHILE IT IS PLUGGED IN,
OPERATING, OR HOT. SEVERE BURNS AND ELECTRICAL SHOCK CAN OC
CUR.
WARNING: Use only in areas free
