THERMOSTAT
CONTROL
OPERATION
The thermostatic control used on these models differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set tempera- ture. The control knob can be set to any 2 comfort level between HI and LO.
Note: The thermostat sensing bulb mea- sures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation loca- tion, room size, open air temperatures, etc.) Frequent use of your heater will let you determine your own comfort levels.
Note: If pilot does not stay lit, refer to |
Troubleshooting, pages 14 through 16. |
Also contact a qualified service person |
or gas supplier for repairs. Until re- |
pairs are made, light pilot with match. |
To light pilot with match, see Manual |
Lighting Procedure on page 13. |
7. Keep control knob pressed in for 30 |
seconds after lighting pilot. After 30 |
seconds, release control knob. |
Note: If pilot goes out, repeat steps |
3 through 7. This heater has a safety |
interlock system. Wait one (1) minute |
