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.
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 use a
line regulator as indicated in the following illustration, or a
line regulator which corresponds to the supply pressure.
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, ANSI Z223.1-(latest edition).

Certified connections are recommended to
be installed as shown, in one plane, and
without sharp bends, kinks or twists. The
gas take off from the supply 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.
