Liquid Propane Gas Regulator In-Line Natural Gas Regulator Power Supply
Installation
1) Determine the desired location for the W8B. It must be mounted at least 18” away from walls or any
flammable material. An 18” clearance must be maintained between the unit and ceiling (18” of chain provided
with W8B). Open flames are present inside the unit, Do not used the unit around flammable materials. Unit
does get warm to the touch.
2) The W8B must be hung correctly for optimum operation. Use the hooks & chains provided with the unit to
secure to ceiling. The unit must be level in order to operate correctly and safe. Tighten all slotted brass caps by
hand, may come loose during shipping.
3) The hose provided is fitted with a standard 3/8” female flare connector. Connect the hose to the back of the
W8B. Use two crescent wrenches or similar to properly tighten the connection. This should be done without
twisting any other connections.
WARNING: Connecting the W8B LP unit to a Natural Gas line, will result in very large flames. Alternatively,
if a W8B-NG is hooked up to propane, this will result in very low and insufficient flames. Make sure your fuel
matches the Generator type.
Propane Generator Only
NOTE: The W8B-LP comes with a standard tank mounted regulator, which should be used unless the
incoming pressure is already regulated to 11” WC (water column).
4) Connect other end of hose to the brass connector on the LP regulator provided. Use the two wrenches again,
one to hold the regulator from the bottom side. The other to twist the 3/8” brass connector on tightly.
5) Open the valve on the propane tank or bigger fuel source. Check the Lines and connections for leaks, by
spraying them with soapy water from a spray bottle. Look for constant bubbling, that would indicate a leak.
Fix leak repeat process.
6) Flip power switch to on position, within 20 sec. unit will begin to spark to ignite the fuel.
Natural Gas Generators Only
NOTE: It is very important to install the regulator “in-Line” between your gas supply and generator. The
regulator supplied with the W8B-NG is present to maintain a constant pressure of 4.5” WC. Which is around ¼
PSI. Before installation, verify your main gas pressure. Most Gas companies install low pressure gas regulators
at the meter that are about ½ PSI. Some commercial buildings have a high pressure gas main (usually around 2
PSI). If the pressure is high, it will need to be reduced to ½ PSI or lower before installing regulator (high
pressure can keep the valves open, causing unit to run with no power).
4) When installing, make sure to install a gas shut-off valve on your line (turn off at main or meter). Install the
shut-off valve in an accessible location. Install the in-line regulator to the gas supply (3/8” NPT female thread).
Connect the hose to the flared fitting on regulator. Using two crescent wrenches or similar to tighten
