Leak Check Fittings

After the first month of continuous use, all regulator, gas and oil fittings should be checked for leaks. A
semi-annual check of these fittings is recommended following the one month initial check.

Replacing Fuses

The GAS-Guard has a variable input power supply capable of receiving input of 115VAC or 230VAC
±15%, 50/60 Hz. Current draw is 6A max. at 115VAC and 3A max. at 230VAC. There are three
4A/250V type 3AG (T) fuses installed for the power supply (line and neutral) and the GAS-Guard's
enclosure heater (line).
CAUTION: Replace fuses with same type and rating only.
