Propane Safety Notes
1. Never overfill your LP-gas container. LPgas containers not
containing a fixed liquid level gauge must be filled by
weight to 80% of their total capacity. Propane expands
1.5% for each 10 °F increase in temperature. 20% of the
container must remain available for expansion. Some tanks
supplied by Alpha Technologies come equipped with automatic stop fill valves. Tanks must be filled in accordance
with manufactures, D.O.T, NFPA Code 58, state and local
regulations.
2. Do not use pliers to close the POL valve on your tank.
These valves are designed to be closed leak tight by hand or
screwdriver as appropriate. If pliers are needed to stop a
vi
leak , the valve needs replacement.
3. When tightening the POL Nut (left-hand thread) on the
service valve, draw it up snug with a proper wrench do not
jam it. No thread sealant is necessary. Check for leaks
after connecting, by using a leak detection solution or soapy
water.
4. If you take your LP-gas tank to a LP-gas dealer for filling,
transport it in the proper position in which it is used (vertical for all Alpha Technologies supplied tanks), with the
valves closed and the POL plug inserted. Secure the tank
against falling or rolling.
5. The outside of the tank should be kept corrosion free by
periodic checks and a coat of paint should be used if needed
(light reflective color).

Propane Safety Notes
6. Do not store LP-gas tanks indoors or in enclosed areas. Do
not expose the tanks to heat, relief valve may open. Always store with the service valve closed tight and plugged.
7. Do not attempt to repair LP-gas containers or valves or
regulators.
8. When using make sure that the tank is level, securely fastened down, and vertical.
9. Check all tank and line connections periodically to be sure
they are tight. When testing for leaks use soapy water or a
leak detect solution. Do not use any open flame for leak
testing.

1. System Overview
1.1 Overview
The CE-X series of enclosures from Alpha Technologies has been
designed to meet the needs of todays outside plant powering requirements.
When an alternate fuel source is not available, the CEG propane natural gas
option can provide up to 16 hours of continuous operation.
The procedures described in this document describe the installation of a
CE-G Series Propane Enclosure. The installation procedures are identical for
the CE-3G and the CE-9G. The cabinet footprint (and mounting hole location)
is identical for each enclosure. The only physical difference between the
enclosures is that the CE-3G is 44 tall and the CE-9G is 52 tall.
