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 as shown in Fig. 10. 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 the sediment trap is not installed or is installed incorrectly, the 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. and 14 in. W.C. Gas supplier provides external regulator for
natural gas.

1) A variety of options are possible for routing the Gas Connection Lines depending on where
your Gas Supply line is located. Install the 3/8'' Fitting to the Heater Cabinet Regulator

your local building code prior to using a Flexible Gas Line for this installation.
