For natural gas operation, the furnace is de- signed for 7" W.C. inlet pressure. Pressure is reduced to 3-1/2" W.C. by the pressure regu- lator in the gas valve. The maximum inlet pressure for the valve is 13” W.C.

For L.P. gas, pressure to the gas valve must be more than 11" W.C. but not more than 13" W.C. Pressure is reduced to 10" W.C. by the pressure regulator in the gas valve.

!CAUTION:

The furnace must be converted by a qualified technician. Improper conver- sion can cause unsafe operation, ex- plosion, fire and/or asphyxiation.

Oil Tank and Piping Installation

The following procedures are recommended as good practice. However, requirements of local codes and ordinances, H.U.D. Manufac- tured Home and Safety Standards or National Fire Protection Association must be satisfied, where they apply, for an approved installation.

Use a tank capacity suitable for the application with a weatherproof, capped fill opening and a shielded vent to let in air as fuel is used. The tank must be clean inside before filling. All water, rust, sediment and other foreign matter must be flushed out.

A fuel or tank gauge is recommended for easy checking of the fuel level. Check the gauge reading with a dipstick.

Locate the storage tank conveniently near the home. For above ground fuel tank installations, the tank may rest three to four inches off the
