GAS SUPPLY INSTALLATION:
The gas connection is located on the left-hand side of the heater cabinet. Insert the pipe to
the gas valve
through the grommet in the cabinet side (see Figure 043.) A union should be installed outside the heater cabi-
net for easy removal of the gas manifold assembly during service.
A CSA certi
fi
ed main gas shutoff valve must be installed outside the cabinet and within 6 feet of the
heater. This valve must have an I.D. large enough to supply the proper amount of gas volume to the heater.
See Figure 034.
ATTENTION
:
Apply joint compound (pipe dope)
sparingly and only to the male threads of pipe joints.
Do not apply joint compound to the
fi
rst two threads.
Use joint compounds resistant to the action of lique-
fi
ed petroleum gas. Do not overtighten the gas inlet
pipe or damage may result.
ATTENTION
: Do not use
fl
exible appliance con-
nectors on any gas connections unless the connector
is CSA approved for outdoor installation, is marked
with BTUH capacity (which must be equal to or
greater than the heater rated input) and the type of gas
(natural or LP).
Reduction of gas supply pipe or tubing to the inlet of the heater gas valve must be made at the valve only
and must match the valve inlet size (3/4” NPT).
If more than one appliance is installed on the gas line, consult the local gas company for the proper gas
line size.
Questions on the installation of the proper gas line size can be directed to Hayward Technical Service.
NATURAL GAS:
The gas meter must have the capacity to supply enough gas to the
pool heater and any other gas appliances if they are on the same pipe-
line (Example: 225 meter = 225,000 BTUH). If doubt exists as to the
meter size, consult the local gas utility for assista
nce. Natural gas must
be “pipeline quality” supplied from a natural gas utility company.
Hayward will not be responsible for heaters that soot up due to im-
proper meter and gas line sizing resulting in improper gas volume, or
heaters that are damaged in any way if connected to a natural gas well.
PROPANE GAS:
All propane gas tanks must be located outdoors and away from pool/spa structure and in accordance wit
h
the standard for storage and handling of propane gas, ANSI/NFPA 58 (latest edition) and applicable local
codes. If the propane gas tank is installed underground, the discharge of the regulator vent must be above the
highest probable water level.
Propane tanks must have suf
fi
cient capacity to provide adequate vaporization for the full capacity of the
equipment at the lowest expected temperatures. Consult a propane company expert for correct sizing.
