THE FOLLOWING:

1.The oven and its individual manual shutoff valve (located at the left rear of the oven) must be discon- nected from the gas supply piping system during any pressure testing of that system at test pressure in excess of 1/2 psig (3.45 kPA). Turn OFF main gas shutoff valve or main gas supply line.

2.The oven must be isolated from the gas supply piping system by closing its individual manual shutoff valve located at the rear of the oven during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psig (3.45 kPA).

3.If incoming w.c. pressure is over 14" w.c. a separate regulator must be installed before the 3/4"manual gas shutoff valve located at the rear outside of the oven.

TROL VALVE REGULATOR DURING INITIAL TURN

ON OF GAS, IT IS

VERY IMPORTANT TO OPEN MANUAL SHUTOFF

VALVE VERY SLOWLY.
