GAS CONNECTIONS AND REGULATION
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).
!
DO NOT USE AN OPEN FLAME OF ANY KIND TO TEST FOR LEAKS.
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 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.
