Gas connections
LP gas installations
LP (propane) gas is heavier than air and
⚠ WARNING
will remain at floor level if there is a
leak. Basements, crawl spaces, alcoves,
and areas below ground level will serve
as pockets for accumulation of leaking
gas. Before lighting, sniff at floor level.
If you smell gas, follow instructions on
page 3 of this manual. Shut off gas at
LP tank outside of the building. DO
NOT operate appliance until leakage is
corrected.
LP gas cylinders shall be located outdoors and away from
the pool structure in accordance with the latest edition of
the Standard for the Storage and Handling of Liquefied
Petroleum Gases, ANSI/NFPA 58, or CAN/CSA B149.2,
and applicable local codes.
NOTICE If an inline high gas pressure regulator
is used, it must be located a minimum of
10 feet from the appliance. Failure to do
so may result in insufficient gas volume
supplied to the appliance.
Gas piping
Figure 6-1_Gas Line Connection to unit w/sediment
trap and manual main gas shut-off valve
All gas connections must be made with pipe joint
compound resistant to the action of liquefied petroleum
and natural gases. All piping must comply with local codes
and ordinances. Tubing installations must comply with
approved standards and practices.
(continued)
Install piping to gas valve
1. The gas line should be a separate line direct from the meter
unless the existing gas line is of sufficient capacity. Verify
pipe size with your gas supplier.
2. Use new, properly threaded black iron pipe free from chips.
If tubing is used, make sure the ends are square, deburred,
and clean. All tubing bends must be smooth and without
deformation. Avoid flexible gas connections. Internal
diameter of flexible lines may not provide the unit with the
proper volume of gas.
3. Install a manual main gas shutoff valve at the pool heater's
gas inlet, outside of the pool heater and before the gas valve.
When the pool heater is installed in, under, or directly
attached to the pool or spa structure, the manual main gas
shutoff valve must be located outside the pool structure.
4. Run pipe or tubing to the pool heater's gas inlet. If tubing
is used, obtain a tube to pipe coupling in order to connect
the tubing to the pool heater's gas inlet.
5. Install a sediment trap (drip leg) in the supply line to the
pool heater's gas inlet (see FIG. 6-1).
6. Apply a moderate amount of good quality pipe compound
(DO NOT use Teflon tape) to pipe only, leaving two end
threads bare.
7. Remove seal over gas inlet to pool heater.
Figure 6-2_Wrench to Support Gas Valve for Piping
Connection
8. Connect the gas pipe to the inlet of the unit. Use a wrench
to support the gas manifold on the unit (FIG. 6-2).
9. For LP gas, consult your LP gas supplier for expert
installation.
10. Ensure that all air is properly bled from the gas line before
starting the ignition sequence. Start up without properly
bleeding air from the gas line may require multiple reset
functions of the ignition control module to achieve proper
ignition.
