GAS SUPPLY (continued)
A steam burner gas valve and dry heat burner gas valve respectively are responsible for the gas supply to the indi-
vidual burners. The Combi-Steamer models CSG have manual shut-off valves, that can be reached from the front
without tools.
The manual shut-off valves of these units are located behind the service cover under the operator panel. To oper-
ate the valves, unscrew the 2 knurled screws and pull the service cover off.
GAS LEAK TEST-CSG
After the piping and fittings have been installed, check for gas leaks. A simple checking method is to turn on the
gas and brush all connections with a soap solution. If bubbles occur, it indicates escaping gas. In this event, the
piping connection must be redone.
GAS PRESSURE-CS
The gas pressure should be measured when all other gas appliances in the kitchen are on high flame. The mini-
mum and maximum incoming line flow pressures should be as follows:
Natural: 7-11” water column
Propane: 11” water column
Installation – Gas Units
(continued)
Never use a lighted match or open flame to test for gas leaks. Escaping gas could cause an explosion resulting in
severe personal injury and/or property damage.
During pressure testing note the following:
1. The Combi-Steamer and its individual shut-off valve must be disconnected 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 shut-off valve or main gas supply line.
2. The appliance 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 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 manual gas
shut-off valve.
