OPERATING

HEATER

Continued

IMPORTANT: This remote control has been specially engineered to take an air temperature sample every 5.5 minutes in the auto mode. It will not respond immediately to the tempera- ture setting being turned up or down.

IMPORTANT: The hand-held re- mote control unit must be near the heater. Do not keep the hand-held remote control unit too close to the heater. The thermostat on the hand- held remote control unit will heat up too quickly and turn the heater off.

3.Use the STATUS button on the hand- held remote control unit to see the operation mode being used and the temperature setting selected. A red light will come on beside the opera- tion mode being used when the sta- tus button is pressed.

4.To turn the burners off when operat- ing in the manual mode, press the OFF button. If operating in the auto mode, press the MAN button, then press the OFF button. The pilot will remain lit. IMPORTANT: To turn the pilot off, manually turn the control knob on the heater to the OFF position.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 25 shows a correct pilot flame pat- tern. Figure 26 shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating the thermocouple. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 26

• turn heater off (see To Turn Off Gas to

Appliance, page 15)

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the fitting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot.

MAIN BURNER

Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with yellow flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may be- come blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Either remove blockage or replace burner. Blocked burner flame holes will create soot.
