BGD258 Series CE Approved Gas Valve Installation Instructions 3
12. Check for leakage at the bleed hole. Paint the
bleed hole with a rich soap and water solution (or
use acceptable gas leak detection equipment). If
bubbles occur, this is an indication of a gas leak.
To stop a leak, tighten the needle screw. Replace
the valve if the leak cannot be stopped.
Note: If installing a valve with a pressure
regulator, set the valve to the desired outlet
pressure. See the Regulator Adjustment
section for specific adjustment procedures.
After setting the valve outlet pressure,
ensure that the leak-limiting seal cap is
replaced (Figure 4).
13. Observe at least three complete operating cycles
to ensure that all components are functioning
correctly before leaving the installation.
Wiring
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connection to avoid electric shock or equipment
damage. Ensure that the operating voltage is
identical to the information on the product
identification label.
The BGD258 valve is supplied with 3-tab or 2-tab
electrical connections. The solenoid coils are male tabs
and electrical connections should be made using
6.35 x 0.8 mm (1/4 in.) female, fully insulated push-on
terminals. The earth ground is clearly labeled.
The electrical wiring to a twin solenoid valve from an
electronic intermittent proven pilot ignition system is
comprised of two lines; a common and an independent
earth ground. Wiring can be done using a single 4-wire
cable. The wiring connections for a 4-wire cable are
shown in Figure 4.
Route the electrical cable for the valve solenoid
actuators from the burner sequence control to the valve
and make wiring connections in accordance with (see
Figure 4).
Note: Electrical connections can also be made using
pre-wired electrical plugs (DIN 43650 Form B [ISO
4400]).
Note: All wiring must be in accordance with national
and local electrical codes and regulations.

WARNING: Risk of Explosion or Fire.
Follow this or an equivalent checkout procedure after
installation. Before leaving the installation, verify that
the gas valve functions properly and that the system
has no gas leaks. Gas leaks can lead to an explosion
or fire, and may result in severe personal injury or
death.
Make sure all components are functioning properly by
performing the following test:
1. Test all joints and connections for leaks with a
soap solution.
2. Close the main upstream shutoff valve and wait at
least 5 minutes for unburned gas to escape from
the appliance, and then reopen the shutoff valve.
3. Turn on the main electrical power switch and close
the thermostat contacts. The appliance should
operate in accordance with the manufacturer’s
specified sequence of operation.
4. Turn the thermostat to a low dial setting to open
the contacts. All burner flames should be
extinguished. Repeat Steps 3 and 4 at least three
times.
5. Return the thermostat to a normal setting before
leaving the installation.
