Replace fan. See Fan, page 8

 

4.

Defective motor

4.

Replace motor. See Motor, page 8

Heater will not ignite.

1. User did not follow installation or op-

 

eration instructions properly

 

2. No spark at ignitor. To test for spark, fol-

 

low step 9 under Ignitor, page 9. 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) Piezo ignitor loose

 

D) Bad ignitor electrode

1.Repeat installation and operation in- structions. See Installation, page 5 and Operation, pages 5 and 6

2.A) Check ignitor wire. Tighten or reat- tach loose ignitor wire. See Figure 17, page 9 for ignitor wire location

B)Set gap between ignitor electrode and target plate to .17"

C)Tighten nut holding piezo ignitor to base of heater

D)Replace ignitor electrode. See Igni- tor, page 9

Heater shuts down while running.

1.High surrounding air temperature caus- ing thermal limit device to shut down heater

2.Restricted air flow

3.Damaged fan

4.Excessive dust or debris in surrounding area

1.This can happen when running heater in temperatures above 85°F. Run heater in cooler temperatures

2.Check heater inlet and outlet. Remove any obstructions
