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:
Disconnect the ready union.
1.
Cut off both sides of the union and discard it.
2.
Create two 2½” diameter holes through the spa panel.
3.
Use two 2” couplings to connect the hoses to 10’ - 15’ 2-3/8” diameter PVC lines.
4.
Connect PVC lines to the gas heater.
