INSTALLATION
CAUTION: Use pipe joint sealant that is resistant to gas (PROPANE or NG). We
recommend that you install a sediment trap in a supply line. Locate sediment trap
where it is within reach for cleaning and not likely to freeze. Install in the piping
system between fuel supply and heater. A sediment trap traps moisture and contaminants.
This keeps them from going into heater controls. If sediment trap is not installed or is
installed incorrectly, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when
connecting into gas piping and/or fittings. NG Models: 6 in. to 14 in. W.C. Gas
supplier provides external regulator for natural gas.
Installation Items Needed (Not Provided)
• 8'' Adjustable Wrench
• 8'' Pipe Wrench
• 1/2'' Flexible Gas Line (24'' Min.) or 1/2'' Black Pipe
• 90 Deg. 1/2 NPT x 3/8'' Flare Fitting or 3/8 NPT x 1/2 NPT' Street Elbow
• Sealant (Resistant to Propane (LP) Gas)
• Shut Off Valve
• Allen Wrench
1) A variety of options are possible for routing the Gas Connection Lines depending on where
your Gas Supply line is located.
NOTICE: Most building codes do not permit concealed gas connections. Check your local build-
ing code prior to using a Flexible Gas Line for this installation.
2) Identify the gas inlet on the Heater that corresponds to the fuel type for your installation. Re-
move the threaded plug by turning counterclockwise.
Install a 90 degree fitting - not included). Be sure to use a gas resistant sealant on the 3/8 NPT
fitting. Position the fitting so the inlet line can be attached without binding.
3) Install the Gas Line to the 90 Deg. fitting and attach to the Shut Off Valve.
4) Check all connections for gas leaks.
Caution: Two gas line installations at the same time are
prohibited.
