INSTALLATION
Battery Arrangements
1. Place the first unit in the exact position it will occupy in the battery.
2. Using a carpenter’s level, level the unit from front to rear and side to side. Adjust as follows:
FLOOR INSTALLATION ON LEGS:
Adjust by turning foot on adjustable legs.
CURB INSTALLATION:
Place shim under the low side. This operation is important since
variations in floors and curbs are common. Unless units are level, difficulty will be encountered in
a aligning the gas supply manifold and the units will not butt together tightly.
3. Remove the upper valve panel from unit.
4. Move the next unit into position.
5. Engage union nut on manifold with male fitting on next unit and draw up union nut hand tight. Be
sure appliances butt together both front and rear. If manifolds do not align, then ranges are not
level. In extreme cases, it may be necessary to loosen manifold bolts and adjust.
6. Continue leveling and connecting gas supply manifolds together until all appliances in the
battery are connected.
7. Tighten manifold union gas tight. Use back up wrench to prevent manifold from rotating.
FAILURE TO DO THIS MAY RESULT IN DAMAGE TO PILOTS AND GAS VALVES.
C CHECK ENTIRE SYSTEM FOR GAS LEAKS.
Gas Hook Up
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the flow of gas
required for satisfactory performance. A steady supply pressure between 7‖ and 8‖ WC for natural
gas and 11‖ and 12‖ WC for propane gas is required. With all units operating simultaneously, the
manifold pressure on all units should not show any appreciable drop. Fluctuation of more than 25%
on natural gas and 10% on propane gas will create pilot problems and affect burner operating charac-
teristics. Contact your gas company for correct supply line sizes.
The unit should be connected
only to the type of gas for which it is equipped. Check type of gas on
rating plate.
1. 1-1/4‖ FRONT MANIFOLD:
The gas manifold of this appliance or of the battery which it is a part must be connected to a gas
a appliance pressure regulator adjusted for the manifold pressure marked on the rating plate.
IMPORTANT
THE UNIT IS EQUIPPED WITH FIXED ORIFICES FOR THE TYPE OF GAS MARKED ON THE
RATING PLATE. THE ORIFICES ARE SIZED FOR THE FOLLOWING MANIFOLD PRESSURE:
NATURAL GAS ..…………. 4.0” WC PROPANE GAS ……………….10.0” WC
