1. Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI
Z223.1), and local building codes. Authorities having jurisdiction should be consulted before the installation
is made. (In Canada, refer to the latest edition of CAN Standard B.149-1 and -2, Installation Codes for Gas
Burning Appliances and Equipment.)
2. All gas supply lines must be located in accordance with the required clearances to combustibles below the
heater as listed on the nameplate of the heater.
3. Pipe joint compounds must be resistant to the action of liquefied petroleum gases.
4. Where local codes do not prohibit, a CSA or U.L. approved flexible connector (minimum 5/8" I.D.) is
recommended between the rigid piping and the heater. A union and an approved shut off valve should be
installed before the control valve inlet. The shut off valve should be installed within 6 feet of the union.
5. This appliance is equipped with a snap-opening, combination gas valve. The maximum supply pressure to the
appliance is 14" W.C. or 1/2 P.S.I. If the line pressure is more than the maximum supply pressure, then a
second stage regulator which corresponds to the supply pressure must be used.
6. If a second stage regulator is used and gas seeps through it, the redundant combination gas valve is designed
to lock out. Pressure build-up in the supply lines prior to the heater must be released before proper heater
operation.
7. After all gas connections have been made, make sure the heater and all gas outlets are turned off before the
main gas supply is turned on. Turn the gas pressure on and check for leaks. To check for leaks, apply a
soapsuds solution to all connections and joints or check by one of the methods listed in Appendix D of the
National Fuel Gas Code.
Do not use an open flame of any kind to test for leaks.

Certified connectors are recommended to be installed as shown, in one plane, and without sharp bends, kinks
or twists. The gas take off from the drop line must be parallel to the burner gas inlet connection.
If the maximum supply pressure is less than ½ psig, a second stage regulator is not required.
