Danger: Do not use candles,
matches or other ignition sources
when checking for gas leaks.
Fuel gases are very flammable
and, in certain concentrations,
explosive. Checking for leaks
with an open flame may lead to
fire or explosion which could
cause personal injury, property
damage, or death.

section
of this manual, then light the heater’s pilot according to the
instructions. The pilot flame should be blue and should appear as
indicated by Figure 7. See the
"M
AINTENANCE
"
section of this manual
for additional information about the pilot.
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
screws which secure the control’s mounting bracket (Item No. 23
of

- found in the upper righthand corner of the
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 "
