INSTALLATION

Continued

7.Open propane/LP supply valve on propane/LP tank(s) slowly. Note: If not opened slowly, excess-ﬂow check valve on pro- pane/LP tank may stop gas ﬂow. If this happens, close pro- pane/LP supply valve and open again slowly.

8.Check all connections for leaks. Apply a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak that must be corrected.

9.Close propane/LP supply valve.

WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pres- sure regulator.

WARNING: A qualified service person must con- nect heater to gas supply. Follow all local codes.

If installing to a fixed fuel piping system, the installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1.

If the heater will be connected to a permanent gas source, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install the external regulator with the vent pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.

CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.

Before installing heater, make sure you have the items listed below.

•external regulator (supplied by installer)

•piping (check local codes)

•sealant (resistant to propane/LP gas)

•equipment shutoff valve *

•ground joint union

•test gauge connection *

•sediment trap

•tee joint

•pipe wrench

*A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. The optional CSA design-certified equipment shutoff valve can be purchased from your dealer. See Accessories, page 18.

Figure 12 - External Regulator With Vent Pointing Down

Installation must include 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 13, page 8).

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.

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.
