but do not force it, Forcing could damage the fitting and
tubing and cause leaking.
Apply liquid leak detector to all connections in the supply line,
manifold and oven to test tor gas leaks. Do
not use an open
flameto
look
for leaks.
Bubbles will form where any gas is
leaking. Turn off the main gas supply before you try to stop
a leak. After all leaks are stopped, turn on the gas supply and
recheck all connections for leaks before lighting burners. All
leaks must be stopped before llghtlng any burners.
After electrical and gas connections have been made, use a
1!8"drill bit to drill holes in the cabinet front, through the holes
in the oven trim. Secure the oven in the cabinet with the
screws provided

MAKING L.P. GAS ADJUSTMENTS
A
If you are using L.P. (bottled) gas, all the
adjustments described below must be
made before you make any burner ad-
justments or use the oven.
To adjust your oven for use with L.P.
gas,
follow the steps
below.
Step 1: Adjust Pressure Regulator
NOTE: The pressure regulator Is set for natural gas. To
use L.P. gas, the regulator must be adjusted.
Locate the pressure regulator (see Fig. 5). Unscrew the cap
and remove the spring retainer, Fig. 6. Turn the retainer over
and put it back into the cap so L-P. is showing on the bottom
end of the retainer.
Replace the cap.

Step 2: Adjust Burner Orifices
CAUTION: The following adjustment must be made
before turnlng on the burner.
Failure to do so could
result in serious Injury due to high flames and toxic
fumes.
Use a l/2" open end or adjustable wrench to turn all orifice
hoods in the L.P. direction, about l-1/2 turns or until snug.
See
next page.
Do not overtlghten or you may distort the
orifice hood and needle.
Pressure Test Information
The maximum allowable pressure for the regulator is 14"
W.C. The minimum pressure needed to check the regulator
setting is 7" W.C. for natural
gas or
11" W.C. for L.P. gas.
CAUTION: The range and lts lndlvldual shut off valve
must be dlsconnected from the gas supply plplng sys-
tem during any pressure testlng ot the gas supply
system at test pressures In excess of l/2 psig (pounds
per square Inch gauge).
The range must be Isolated irom the gas supply plping
system by closing its lndlvldual
shut
off valve during
any pressure testlng of the gas supply system at test
pressures equal to or less than l/2 psig.
