GAS CONNECTION - LIQUID PROPANE (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 may
have 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
• CSA 6.27
, and suitable for outdoor installation. The connection shall be 48 inches (1.22 m) or
less.
NOTE: To ensure proper heating performance of this appliance, verify that the gas line supply
pressure is adequate. Use only the gas pressure regulator supplied with this appliance. The
regulator must be set for a supply pressure of 11” WC (2.74 kPa) to maintain 10” WC (2.49 kPa)
outlet (manifold) pressure. Use a minimum 1/2” ID flex hose to prevent gas starvation. Ensure
that the service pipe supplying the Power Burner is fitted with a shut-off valve conveniently
positioned and easily accessible as an emergency gas shut-off.
Your Hestan Power Burner for use with LP Gas Piped Systems is supplied with a special
convertible regulator which MUST NOT be removed. If this regulator needs to be replaced, use
only the type specified by Hestan for this appliance.
To connect the gas supply, follow the next steps:
1. Locate the regulator mounted underneath your Power Burner and install a 1/2”NPT elbow
and nipple as shown above. The nipple should be at least 3” long.
2. Connect gas supply using a minimum 1/2” diameter flexible (semi–rigid) stainless steel gas
hose, no more than 48” in length. Be sure to use proper fittings and a flexible hose as short
as possible to make the connection. The hose as well as the connectors must comply with
the
Standard for Connectors for Outdoor Gas Appliances and Manufactured Homes, ANSI
Z21.75 • CSA 6.27
, and suitable for outdoor installation. Use the appropriate thread sealant
on all connections.
3. Proceed to LEAK TESTING section.
