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
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: 5 in. to 10.5 in. W.C. Gas
supplier provides external regulator for natural gas.
