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.
1. Turn on the main gas supply to the system.
2. Turn on the power to the electrical elements.
a. Wait 15 minutes. BE58 models, energize
solenoid depending on your voltage (12 Vdc or
24 Vdc) to activate the power unit, allowing power
to stay on for 30 – 45 seconds. After turning off
power to the solenoid, the internal seat will
remain open, allowing gas to flow to the heater.
b. If power is lost to the solenoid, wait
15 minutes. Use manual override button
(optional) on some BE58 models by depressing
the reset (see Figure 2) if there is no power to the
solenoid. Releasing pressure on the reset allows
the button to return to its original position and
internally open the valve, allowing gas to flow to
the heater.
Figure 2: Manual Override Operation
Note: If the valve does not stay open when the
reset button is released, it may be necessary to
wait an additional few minutes and then depress
the reset or activate again.
3. When the catalytic reaction is well established,
turn off the power to the electrical coil.
Note: This coil is not designed for continuous
duty.
4. Check the millivoltage output of the thermocouple
and milliampere dropout range at the BASO
power unit terminal to be sure that they meet the
values in Table 1. Step-by-step procedures for
these checks are included with the Y99AB-4
BASO Test Kit Application Note
(Part No. BASO-AN-Y99AB).

WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing. Failure to shut off
the gas supply can result in the release of gas during
installation or servicing, which can lead to an
explosion or fire, and may result in severe personal
injury or death. Coil is not designed for continuous
duty. If the coil is left on, with the gas connected and
left on, this can lead to an explosion or fire, and may
result in severe personal injury or death.
Field repairs must not be made to the BE58 remote
valve. Any attempt to repair this assembly voids the
manufacturer’s warranty. For a replacement valve,
contact the original equipment manufacturer or the
nearest BASO Gas Products distributor.
