Caution: If the wall on which the heater is mounted is bowed or
uneven in the vicinity of the heater, the heater's cabinet might be in
a bind which may not allow the heater's control knob to move up
and down freely enough to function as described by the heater's
lighting instructions. If the control knob will not depress and spring
back into position freely due to a bowed or uneven wall, do the
following: Turn the gas off at the shutoff valve. Loosen the four
t o t h e
screws which secure the control's mounting bracket (Item No. 23

heater. Slide the loosened mounting bracket either right or left until
the control knob will depress and spring back into position freely.
Leave the bracket at that location and retighten the screws.
Recheck for gas leaks as directed. Relight the heater's pilot, and
proceed to Step 19.
18. Immediately after the heater's pilot is lit, use a soap-water solution
or a liquid gas leak detector to check each joint in the heater's pilot
tubing for gas leaks. If any leaks are found, turn shutoff valve off
and repair all leaks before proceeding.
19. After the pilot flame is established, turn the heater's control knob to
'"High". If the burner plaques do not light within four seconds, turn
the control knob to "Pilot" and read the "
of this manual for help in determining what the problem may be.
