Roper MN11020(344197), B875 manual Making L.P. Gas Adjustments

7.TWO lower trim pieces are provided. If you have extended the leg levelers 34” or more, use the taller trim. Attach to the unit with the 3 screws supplied and to the cabinet below with the 2 wood screws supplied.

If leg levelers are extended less than 3/4”, use the shorter trim. Attach to the unit with the 3 screws supplied.

REGULATOR

If you are using L.P. (bottled) gas all the adjustments described below must be made before you make any burner ad-

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.

If you are replacing an older unit that had a cutout height of more than 38” (39” to 39-318” are normal, alternate standards) follow steps below:

1.Measure by how much your cutout height exceeds 38”.

2.Relocate and raise your gas inlet pipe if necessary. See

figure 4. The 2-112” dimension (shown in figure 4) need only change if yourcu!out height is more than 38-l/2”. If ‘your cutout height is more than 38-l/2”, increase the 2- 1’2” dimension shown In figure 4 by amount measured in step 1I above.

3.Remove the storage drawer (see Care and Cleaning section of Use and Care Manual).

4.Extend the leg levelers (using a 3116” hex socket driver or a flat bladed screw driver) by the amount measured in step 1, above.

Step 2: Adjust Burner Orifices

CAUTION: The following adjustment must be made before turning on the burners. Failure lo do so could result in serious injury due to high flames and toxic fumes.

Use a li2”open end or adjustable wrench to turn both orifice hoods in the L.P. direction, about l-l/2 turns or until snug. See next page. Do not over-tighten or you may distort the orifice hoods and needles.

Pressure Test Information

	The maximum allowable pressure for the regulator is 14”
	W.C. The minimum pressure needed to check the regulator
	setting is 5”: W.C. for L.P. gas.
	CAUTION:	The range and its individual shut off valve
	must be disconnected from the gas supply piping sys-
	tem during any pressure testing of the gas supply
5. Insert the oven in the cutout and adjust leg levelers so	system at test pressures in excess of 112psig (pounds
	per square inch gauge).
