INSTALLATION
Continued
Installation must include an equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 12).
IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.
Check your building codes for any special re- quirements for locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.
WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

adjustment.
We recommend that you install a sediment trap in supply line as shown in Figure 12. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or
is installed wrong, heater may not run properly.
CAUTION: Avoid damage to gas control. Hold gas control with wrench when connecting it to gas piping and/or fittings.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detec- tion fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and heater. See guidelines un- der Connecting to Gas Supply, page 12.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage heater regulator.
2.Cap off open end of gas pipe where equipment shutoff valve was connected.
