Use proper gas type for the replace unit you are
installing. If your gas supply is not correct, do not
install replace. See retailer where you purchased
the replace for proper replace according to your
gas type or to purchase gas conversion kit (see
Accessories, page 39).

Installation Items Needed
Before installing replace, 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 *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved exible gas line with gas connector
(if allowed by local codes)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alterna-
tive to test gauge connection. Purchase the CSA
design-certied equipment shutoff valve from
your retailer.
For propane/LP connection only, 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 pres-
sure, replace regulator damage could occur. Install
external regulator with the vent pointing down as
shown in Figure 37. Pointing the vent down protects
it from freezing rain or sleet.
CAUTION: Use only new,

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 replace (see Figure
38, page 24).
IMPORTANT: Install main gas valve (equipment
shutoff valve) in an accessible location. The main
gas valve is for turning on or shutting off the gas
to the appliance.
Check your building codes for any special re-
quirements for locating equipment shutoff valve
to replaces.
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 replace valves.
