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 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 H19. 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 does not exceed the limits in the
Technical Specifications section.
To install the H19 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.
4. Mount the valve to the pipework. The H19 valve
may be mounted in any convenient position. In
Liquefied Petroleum (LP) gas applications, mount
the valve high enough to prevent entry of fuel in
the liquid state. Use and 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
(NFPA 54).
