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 18, MSVFBNR series, or Figure 19, MSVFBN series).

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

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 seal- ant that is resistant to liquid pe- troleum (LP) gas.

• test gauge connection *
•	sediment trap
•	tee joint
•	pipe wrench

*An CSA/AGA design-certified equip- ment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connec- tion. Purchase the optional CSA/AGA de- sign-certified equipment shutoff valve from your dealer. See Accessories, page 23.

The gas inlet connection 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
