Installation
IMPORTANT: Only qualified personnel should
install or service BASO Gas Products 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 Electrical Shock.
Disconnect power supply before making electrical
connections to avoid electrical 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 H15. 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 H15 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 main gas flow through the gas
valve body must be in the direction indicated by
either “IN” and “OUT” or 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 H15 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 H15 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 and Figure 2.)
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.
