GAS CONNECTION - LIQUID PROPANE (LP) CYLINDER
Your Hestan grill for use with LP gas is supplied with a two-stage regulator/hose assembly
for connection to a standard 20 lb. LP gas cylinder. This assembly must be used WITHOUT
alteration. If this assembly needs to be replaced, contact your Hestan dealer for genuine
replacement P/N 006256.
NOTE: To ensure proper heating performance of this appliance, verify that the supply pressure is
adequate (11.0” WC supply pressure is preferred) to maintain 10.0” WC manifold pressure.
To connect the regulator / hose assembly follow these steps:
1. Locate the regulator and gas connection point in the rear right side of your grill (in cart-
mounted models, remove the rear panel to gain access).
2. Connect the regulator/hose assembly to the 3/8” Flare (compression flare fitting) X 1/2” NPT
female adapter as shown.
3. Connect the regulator/hose assembly to a standard 20 lb. LP cylinder. The hose as well as the
connectors must comply with the
Standard for Connectors for Outdoor Gas Appliances and
Manufactured Homes, ANSI Z21.75 • CAS 6.27
, and suitable for outdoor installation. Use the
appropriate thread sealant on all connections.
4. Proceed to LEAK TESTING section.
GAS CONNECTION - LP PIPED SYSTEMS
An LP piped system is one with a large central LP tank that feeds an entire household. These
systems are normally equipped with a high pressure regulator by the large LP tank, and low
pressure regulators close to the home. The gas line connectors must comply with the
Standard
for Connectors for Outdoor Gas Appliances and Manufactured Homes, ANSI Z21.75 • CAS 6.27
,
and suitable for outdoor installation. The connection shall be 6 feet (1.82 m) or less.
NOTE: To ensure proper heating performance of this appliance, verify that the supply pressure is
adequate (11.0” WC supply pressure is preferred) to maintain 10.0” WC manifold pressure.

LP TANK RESTRAINT
If you purchased a Hestan Grill on a cart, be sure to restrain the LP cylinder by securing it with
the retention bolt on the slide-out tray as shown below. It is important the tank does not fall
over or stretch the hose which could cause a gas leak.
LEAK TESTING
GENERAL
Although all gas connections on your Hestan grill are leak tested at the factory prior to
shipment, a complete gas tightness check must be performed at the installation site due to
possible movement in shipment, or excessive pressure unknowingly being applied to parts of the
unit. Periodically check the whole system for leaks, or immediately check if the smell of gas is
detected.
BEFORE TESTING
• Do not smoke while leak testing.
• Never leak test with an open flame.
• Make a soap solution of one part liquid detergent and one part water for leak testing
purposes.
• Apply the solution to the gas fittings by using a spray bottle or a brush.
• For LP units, always check with a full LP cylinder.
