Raypak 055B Auxiliary Bypass Valve Adjustment, Pressure Relief Valve Installation

Page 14

EXTERNAL AUXILIARY BYPASS VALVE (Where required)

An auxiliary bypass valve should be used when flow rates exceed 60 GPM (usually a high performance pump size larger than 1 1/2 HP will exceed this flow rate). This valve is required to complement the function of the automatic bypass valve, particularly when start- ing the heater in winter or early spring when the spa or pool temperature is down below 55°F. It also serves to eliminate needless pressure drop through the heater and accompanying reduction in the flow rate to the spa jets, etcetera.

AUXILIARY BYPASS VALVE ADJUSTMENT

To set bypass: With clean filter, adjustment is made by feeling the inlet and outlet pipes at the heater. Outlet pipes should be slightly warmer than inlet and comfortable to the touch. If pipe is hot, close bypass; if cold, open bypass

PRESSURE RELIEF VALVE INSTALLATION

To conform to local building codes, it may be necessary to install a pressure relief valve. A 3/4" pressure relief valve having a capacity equal to BTU/ HR output of the model to be installed is recommended for this appliance.

Drain Pipe

Drain Pipe

throughout its entire length and must pitch downward from the valve. No shut-off valve shall be installed between the relief valve and the drain line. Valve lever should be tripped at least once a year to ensure that waterways are clear.

ELECTRICAL WIRING

NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105 °C wire or its equivalent, except all black wire must be replaced with 150 °C wire or its equivalent.

MILLIVOLT SYSTEM

The Millivolt System Residential Heater is equipped with a self-generating electrical system in which the electric current is provided by means of a pilot generator. No external electrical connections are required.

ELECTRONIC INTERMITTENT IGNITION DEVICE SYSTEM (IID)

NOTE: When the electrical hookup to the heater requires both 24V and 115V or 240V, each input voltage must be isolated in separate conduit.

The Electronic Intermittent Ignition Device auto- matically lights the pilot and main burners upon a call for the heat. The heater is supplied with a dual voltage transformer for 120V or 240V input power hookup.

NOTE: IID Propane Units Only

Heater is equipped with an electronic ignition device with a 100% safety lockout feature. If the heater fails to start or lockout. Reset the ignition device by inter- rupting the power to the heater for 60 seconds.

CAUTION: If service replacement of the electronic ignition device is required. Replace only with a 100% safety lockout device with 90 second trial for pilot ignition.
