E. Gas Supply for the SteamChef
INJURY, DEATH, AND PROPERTY DAMAGE WILL RESULT.
If the installer smells gas, or suspects there is a gas leak, immediately refer to
the posted gas leak instructions. The posted instructions are provided by the
local gas supplier and supersede any other instructions.
If a gas leak is suspected, observe the following precautions in addition to the posted instructions:
• Do NOT light or start any appliance.
• Do NOT touch any electrical switch.
• Do NOT use any phone in the building.
• Immediately call the gas supplier from a phone away from the building.
• Follow the gas supplier's instructions.
• If the gas supplier cannot be reached, call the fire department.
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 3-1.
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 3-1 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 1-2
d. Install main manual shut off valve between gas supply and the SteamChef. See Figure 3-3. 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 3-3.
