Gas Heater Hook Up - Cal Spas 5100 Owner's Manual

Gas Heater Hook up

Ultimate Fitness Series spa owners may buy and install a separate gas heater and pump for use with their spa. This
option may be purchased separately from your local distributor.
Spa owners are responsible for ensuring installation of their gas heater conforms to local, state, and federal
regulations. The electrical and gas installation must be performed by contractors and approved by a local building /
electrical inspector. Failure to do so may void your warranty.
All Ultimate Fitness Series spas are plumbed with a gas heater ready union located inside the cabinet at either the
front or rear, depending on the model. (See the figures below and at right.) Properly installed, they can be attached
to an external gas heater. Customers are responsible for creating openings in the panel to accommodate the lines
and wiring. The gas heater should be located not less than 10 feet and no more than 25 feet away from the spa.
To connect the plumbing for an external gas heater:
1. Disconnect the ready union.
2. Cut off both sides of the union and discard it.
3. Create two 2½" diameter holes through the spa panel.
4. Use two 2" couplings to connect the hoses to 10' - 15' 2-3/8" diameter PVC lines.
5. Connect PVC lines to the gas heater.
