REMOTE OPERATION

Note:

 

All remote control accessories must be 

purchased separately (see 

Accessories, 

page 

42).  Follow  instructions  included  with  the 

remote control.

NOTICE: You must light the pilot 

before  using  the  hand-held  re-

mote control unit. See 

Lighting 

Instructions

 on page 22.

After lighting, let pilot flame burn for about 

one minute. Turn control knob to ON posi-

tion. Adjust flame adjustment knob anywhere 

between HI and LO. Slide the selector switch to 

the REMOTE position (see Figure 33). 

Note:

 

The burner may light if hand-held remote was 

on when selector switch was last turned off. 

You can now turn the burner on and off with 

the hand-held remote control unit. 

IMPORTANT:

 Do not leave the selector switch 

in the REMOTE or ON position when the pilot 

is not lit. This will drain the battery.
