* 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 30.
The gas regulator for the stove heater is located on the lower right-hand side of the
stove when viewed from the front of the unit. The gas connection can be made either
through the bottom right side or through the lower back opening as illustrated in
Figure 17. Make sure gas log heater is secured to the stove cavity assembly.

Never connect heater to private (non-utility) gas wells. This gas is
commonly known as wellhead gas.
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 1/2" diameter or greater to allow proper gas volume to
heater. If pipe is too small, undue loss of pressure will occur.
Installation must include a manual shutoff valve, 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 18, page 16).
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.
Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown in Figure 18, page 16. Locate sedi-
ment trap where it is within reach for cleaning. Locate sediment trap where
trapped matter is not likely to freeze. A sediment trap traps moisture and contami-
nants. This keeps them from going into heater controls. If sediment trap is not
installed or is installed wrong, heater may not run properly.
