TROUBLESHOOTING

WARNING: Never service heater while it is plugged in, connected

to propane supply, operating or hot. Severe burns and electrical

shock can occur.

REMEDY

1. Check voltage to electrical outlet. If

voltage is good, check heater power

cord for breaks

2. Adjust motor/fan mount to keep fan

from hitting inside of heater shell. Bend

fan mount if necessary

3. Replace fan. See Fan, page 9

4. Replace motor. See Motor, page 8

1. Repeat installation and operation

instructions. See Installation, page 4

and Operation, page 5

2. A) Check ignitor wire. Tighten or

reattach loose ignitor wire. See Figure

10, page 9 for ignitor wire location

B) Set gap between ignitor electrode and

target plate to .13"/.15" (

3.3 a 3.8 mm)

C) Replace ignitor electrode. See

Ignitor, page 10

D) Replace spark transformer. See

Spark Transformer, page 9

1. A) Reﬁll tank

B) Provide additional and/or larger

tanks. See Propane Supply, page 4

2. This can happen when running heater

in temperatures above 85°F. Run

heater in cooler temperatures

3. Check heater inlet and outlet. Re-

move any obstructions

4. Replace fan. See Fan, page 8

5. Clean heater. See Maintenance,

page 5

1, Check all connections for leaks. Ap-

ply mixture of liquid soap and water

to gas joints. Bubbles forming show

a leak that must be corrected

2. To obtain correct mixture of propane/

LP gas and air, use a larger cylinder

size, i.e. 40 lb.(minimum) or 100 lb.

See Propane Supply, page 4

3. A) Use a larger supply cylinder size,

i.e. 40 lb. (minimum) or 100 lb.

B) Reduce consumption rate by op-

erating the heater at "LOW" setting

temorarily until frost disappears from

the tank

POSSIBLE CAUSE

1. No electrical power to heater

2. Fan hitting inside of heater

shell

3. Fan blades bent

4. Defective motor

1. User did not follow installa-

tion or operation instructions

properly

2. No spark at ignitor. To test for

spark, follow step 8 under Ig-

nitor, page 10. If you see spark

at ignitor, have heater serviced

by qualiﬁed service person. If

no spark seen:

A) Loose or disconnected

ignitor wire

B) Wrong spark gap

C) Bad ignitor electrode

D) Bad spark transformer

1. Propane supply may be inad-

equate

2. High surrounding air tem-

perature causing thermal limit

device to shut down heater.

3. Restricted air ﬂow

4. Damaged fan

5. Excessive dust or debris in

surrounding area

1. Gas leak

2.

Heater operating on a 20lb. pro-

pane/LP cylinder. Insufficient

propane/LP gas will be supplied by

a 20lb. cylinder resulting in odor

3. Propane/LP supply tank is

"freezing up". Evaporation

and consumptioin rate of pro-

pane from supply tank is to

great for the size of the tank

and air temperature

OBSERVED FAULT

Fan does not turn when

heater is plugged in

Heater will not ignite

Heater shuts down while

running

Heater producing odor

WARNING: Use only in areas free of high dust content.
