CAUTION
sediment trap should be located within reach for cleaning and where it is not likely to freeze. Install it in the
piping system between the fuel supply and heater. This keeps contaminants from getting into the heater
controls. The heater may not run properly if the sediment trap is not installed or is installed incorrectly.
CAUTION
(R-Series). Your gas supplier provides an external regulator for natural gas.
INSTALLATION ITEMS NEEDED (NOT PROVIDED):
• 8" Pipe Wrench
• 8" Adjustable Wrench
• Shutoff Valve
1. Depending on where your gas supply line is located, a variety of options are possible for routing the gas
connection lines. First remove the plug from the regulator for the type of fuel you're using. Install a 3/8"
NPT fitting to the heater regulator using sealant. Use of a 90 degree elbow will allow for the minimum
clearance to a wall.
NOTICE: Most building codes do not permit concealed gas connections. Check your local building
code before using a flexible gas line for this installation.
2. Install the gas line to the fitting, and attach it to the shutoff valve (see Fig. 16 & 17).
3. Check all connections for gas leaks.

Installation (cont.)
Use pipe joint sealant that is resistant to gas (propane or NG). We recommend that you
install a sediment trap in a supply line, which traps moisture and contaminants. The
Avoid damage to the regulator. Hold the gas regulator with a wrench when connecting
into gas piping and/or fittings. NG Models:
• 3/8" Flexible Gas Line (24" Min.) or 1/2" Black Pipe
• 90 Deg. 3/8 NPT x 3/8" Flare Fitting or 3/8" Street Elbow
• Sealant (Resistant to natural or propane/LP gas)
