GAS PIPING

The gas inlet pipe size is 1/2" NPT to the gas valve. Provide an adequate size gas supply line. The line should not be smaller than 1/2" NPT according to the chart below.

Gas piping must have a sediment trap ahead of the heater gas controls and a manual shut-off valve lo- cated outside the jacket. A manual shut-off valve is provided loose and must be installed at the site.

The heater and its gas connection shall be leak tested before placing the heater in operation.

The heater and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

The heater must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

Dissipate test pressure from the gas supply line before re-connecting the heater and its manual shut-off cock to the gas supply line. FAILURE TO FOLLOW

THIS PROCEDURE MAY DAMAGE THE GAS VALVE. OVER PRESSURED GAS VALVES ARE NOT COV- ERED BY THE WARRANTY. The heater and its gas connections shall be leak tested before placing the appliance in operation. Use soapy water for leak test. DO NOT use open flame.

NOTE: DO NOT use teflon tape on gas line pipe threads. A flexible sealant suitable for use with Natural and Propane gases is recommended.

The maximum inlet gas pressure must not exceed the value shown above. The minimum gas pressure shown is for the purposes of input adjustment.

The gas valve is provided with a pressure tap to measure the gas pressure downstream, which is also the manifold pressure.

WATER PIPING

The inlet and outlet water connections are 3/4 in. NPT. A water pressure regulator is shipped loose with the heater. Install, as needed, between the booster heater and dishwasher lines. Adjust setting to maintain 20 PSI at the dishwasher.

Install a suitable water hammer arrester be- tween the booster heater and dishwasher, as shown on page 10, typical piping.
