INSTALLING
FURNACE

Installation must include a manual shutoff valve (supplied), ground joint union,
plugged I/8" NPT tap, and a sediment trap. Locate NPT tap within reach for test
gauge hook up. NPT tap must be upstream from furnace (see Figure 15).
Apply pipe joint sealant lightly to male threads. Prevent excess sealant from going
into pipe. Excess sealant in pipe could result in clogged furnace valves.
CAUTION
Use pipe joint sealant that is resistant to liquid petro-
leum (LP) gas.
Install sediment trap in supply line as shown in Figure 15. Locate sediment trap
where it is within reach for cleaning. A sediment trap traps moisture and contami-
nants. This keeps them from going into furnace controls. If sediment trap is not
installed or is installed wrong, furnace may not run properly.
IMPORTANT." Locate sediment trap where trapped matter will not freeze. Install
sediment trap in a vertical run of pipe. If gas piping enters furnace from rear
(outside), you must locate sediment trap in crawl space (see Figure 15). If you
install furnace in structure with slab foundation, you must install gas piping to
front of furnace (inside) (see Figure 15).
