Water Requirements

The gas valve is provided with a pressure tap to measure gas pressure downstream, which is also the manifold pressure (fig. 5.). The gas piping must have a sediment trap ahead of the heater gas controls and an approved manual shut-off valve (provided by others) located outside the jacket and easily accessible. The heater and its gas connections must be leak tested before placing the appliance in operation. DO NOT use an open flame for leak testing. The heater must be isolated from the gas supply piping by closing its individual manual shut-off valve during any pressure testing of the gas supply piping at test pressures equal to or less than 1/2 p.s.i.g. (3.5 kPa). The heater and its individual shut-off valve must be disconnected from the gas supply during any pressure testing of that system at test pressures in excess of 1/2 p.s.i.g. (3.5 kPa). Dissipate test pressure from the gas supply line before re-connecting the heater and its manual shut-off valve to the gas supply line.

CAUTION: Failure to follow this procedure may damage the gas valve and cause a dangerous condition. Over pressured gas valve damage is not covered under warranty.

NOTE: Do not use Teflontm tape on gas line threads. Use only a flexible thread sealant approved for use with fuel gases.

Local water conditions vary greatly between even near-by locations and can greatly affect the performance and maintenance requirements of warewashing equipment, including your booster heater. Proper water conditions will provide lower chemical costs, improved cleaning performance, reduced spotting and longer equipment life as well as more efficient labor use and reduced damage to dishware and utensils. Proper water treatment for effective and efficient performance of this equipment will vary depending upon the make- up of the local water supply.
