H17 Series BASO® Automatic Pilot Valve
Application
The H17 Series pilot valves provide complete shutoff
in the event that the flame heating the thermocouple is
extinguished. Applications include room heaters,
infrared heaters, salamanders, and refrigerators.
H17 models are also available with a higher ambient
temperature, up to a maximum of 300
°F (149°C), for
use on commercial ovens, broilers, and other
applications.
IMPORTANT: Only qualified personnel should
install or service BASO® Gas Products. These
instructions are a guide for such personnel. Carefully
follow all instructions in this document and all
instructions for the appliance.
IMPORTANT: Make all gas installations in
accordance with applicable local, national, and
regional regulations.
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connections to avoid electric shock.
Note: In applications that do not require electrical
power, disregard the above caution.
!
WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing the H17. 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.
IMPORTANT: Verify that the valve is installed
only in applications where the specified maximum
ambient (surface) temperature and maximum
operating pressures do not exceed the limits in the
Technical Specifications section.
To install the H17 valve:
1. Shut off power to the appliance (if applicable).
2. Shut off the gas at the main manual shutoff valve.
3. Ensure that the gas flows through the valve body
in the direction indicated by the arrow on the
valve body. If the valve is installed with the gas
flow in the opposite direction of the arrow,
leakage can occur.
IMPORTANT: Do not use a wrench on any
surface other than the casting flats provided at the
inlet and outlet ends of the valve body. The H17 may
be damaged in the mounting process if a wrench is
used on any other surface. Using a wrench
incorrectly may void the warranty.
4. Mount the valve to the pipework. The H17 valve
may be mounted in any convenient position. Use
an approved pipe joint sealing compound on the
male threads before assembly. Remove excess
compound after mounting the valve to the
pipework. Threads of the pipe and nipples must
be smooth and free of tears and burrs. Steam
clean all piping to remove foreign substances
such as cutting oil or thread chips. A sediment
trap should also be installed in accordance with
the National Fuel Gas Code (ANSI Z223.1). See
Figure 1.
5. Attach the thermocouple securely to the pilot
burner, and screw the terminal end to the
BASO® power unit terminal on the valve. Make
sure this connection is clean. Tighten the
thermocouple lead nut finger tight plus a
maximum of 1/8 turn. Do not overtighten.
