GAS RESIDENTIAL HEATERS
INSTALLING
TO WALL
Continued
4.If installing bottom mounting screw into hollow or solid wall, install wall anchor. Follow steps 1 through 5 under Attaching To Wall Anchor Method, page 7.
If installing bottom mounting screw into wall stud, drill hole at marked location using 9/64" drill bit.
5.Replace heater on wall.
6.Insert bottom anchor screw through back panel into bottom anchor or drilled hole (see Figure 11).
7.Tighten screw until heater is firmly secured to wall. Do not over tighten.
Note: Do not replace front panel at this time. Replace front panel after making gas connections and checking for leaks (see page 9).
could occur. Install 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. Inter-
Installation must include a manual shutoff valve, ground joint union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be up- stream from heater (see Figure 13).
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.
CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within reach for cleaning. Locate sedi- ment 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.
IMPORTANT: Hold pressure regulator with wrench when connecting it to gas piping and/ or fittings.

CONNECTING TO GAS SUPPLY
NOTICE: A qualified service person must connect heater to gas supply. Follow all local codes.
CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator be- tween the heater and propane/LP supply.
The installer must supply an external regu- lator. The external regulator will reduce incoming gas pressure. You must reduce

*An A.G.A. design certified manual shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional A.G.A. design certified manual shutoff valve from your dealer. See Accessory, page 12.
