WARNING:
For your safety, if you smell gas: (A) turn off gas at line valve or meter, (B) open windows,
(C) do not touch electrical switches, (D) extinguish all open flames, (E) immediately call
your gas supplier.
4. When using L.P.gas, the Control must be equipped with a regulator. Make sure that no gas is present in
the area before putting machine in operation. L.P. gas is heavier than air. Sniff at floor level for pres-
ence of gas. If present do not attempt to start the machine. (See Warning on page 8.) When changing
from natural gas to L.P., or L.P. to Natural Gas using a convertible control, the burner orifice and pilot
orifice must also be changed.
5. Make certain that the pilot orifice being used is the correct size for the gas used.
6. To install or remove control, use a special body wrench on inlet boss. Do not grip body with pipe wrench
or vise.
7. Insert only correct size pipe or tubing into inlet or outlets of control. Insertion of any other objects can
cause internal damage resulting in a hazardous condition.
8. Make sure gas piping is pressure tested before control is connected. High pressure can damage control
causing a hazardous condition. Do not subject control to more than 1/2 P.S.I., (14" W.C.) inlet pressure.
9. Use only new, unused, and correct model controls as replacements. Do not re-use old controls.
10. Make sure piping is clean and free from burrs. Apply a small amount of good quality pipe thread com-
pound suitable for the gas being used. Thread compound should be used sparingly on male threads
only, leaving the first two threads clean. NOTE: Blow lines out with compressed air to remove all dirt or
debris.
11. A drip leg (dirt trap) must be installed, after the shut-off valve, in the gas supply line to the control to
prevent dirt from entering control.
See Figure #1.
All piping must conform to local codes and ordi-
nances and with National Gas code (ANSI Z223.1 and NFPA No. 54).
12. After installation has been completed, leak test all gas connections with soap solution with the main
burner on. Bubbles indicate leaks that must be corrected.
13. If control has been exposed to water in any way, it must be replaced.
14. Keep combustible material away from gas machine. Keep burner area clean and free of dust and lint.
15. If gas valve fails to shut off, do not turn off electrical power. Turn off gas supply allowing water pump to
continue running until system has cooled. Replace control.
