E. Gas Supply for the SteamChef
1.
Gas Supply Requirements
•
Gas supply type MUST match the type of gas shown on the rating plate.
•
Gas supply pressure must NOT exceed 14” water column (1/2 psi), and fall within the acceptable
pressure range shown below when using 3/4” NPT line and a 1/2” NPT connection
•
Natural gas pressure at 1000 BTU/CF must be between 7” – 14” water column.
•
If the gas supply pressure exceeds 14” water column, a pressure regulating valve (pressure
regulator) must be installed in gas supply plumbing to reduce pressure to the SteamChef. See
Figure 3-2.

Installation of the Gas Supply Lines
The Installer / owner is responsible for furnishing and installing gas supply lines, valves,
regulators, and accessories.
When installing gas supply lines and accessories, observe the following:
a. Refer to Figure 3-2 for the recommended layout of the gas supply lines.
b. Use a non-hardening pipe thread sealant resistant to LP gas.
c. The ½” NPT gas inlet is on the back of the SteamChef. See Figure 2-1
d. Install main manual shut off valve between gas supply and the SteamChef. See Figure 3-2. This
main manual shut off valve is called the “Main Manual Gas Valve.”
e. Install a sediment trap (drip leg) in gas supply line. See Figure 3-2.
3.
Testing Gas Supply Lines
1) Test all pipe joints for leaks with soap and water solution.
2) Check all connections for proper tightness.
3) Remove the control side panel to inspect gas connections inside the SteamChef.
4) Open the gas supply valves.
5) Check all lines and connections for leaks, both inside and outside the SteamChef.
6) All leaks must be corrected before attempting to operate the SteamChef.
7) Replace the side panel and secure it to the SteamChef before starting the SteamChef.
4.
Pressure Testing Gas Supply Lines
If any pressure testing is required, the SteamChef must be disconnected or isolated from the gas
supply piping system during any pressure testing as follows:
