Installation
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 previous caution.
!
WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing the H43. 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 pressure do not exceed the limits in the
Technical Specifications section.
To install the H43 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 install 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 H43 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. Mount the H43
valve in any convenient position with the reset
button and manual valve handle accessible. 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 needs to be installed in accordance with the
National Fuel Gas Code NFPA 54 (Figure 1).
