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 14).

IMPORTANT: Install equipment valve in an acces- sible 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.

We recommend that you install a sediment trap in supply line as shown in Figure 14. 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 regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings.

CHECKING GAS CONNECTIONS

WARNING: Test all gas pip- ing and connections, internal and external to unit, for leaks after installing or servicing. Cor- rect all leaks at once.

WARNING:Neveruseanopen flame to check for a leak. Apply a noncorrosive leak detection fluid toalljoints.Bubblesformingshow a leak. Correct all leaks at once.

CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and heater.SeeguidelinesunderCon- necting to Gas Supply, page 13.

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.

3. Pressurize supply piping by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using com- pressed air.

4. Check all joints of gas supply piping system. Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5. Correct all leaks at once.

6. Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.
