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 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 connec-
tor (if allowed by local codes)
* A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative 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" of water. If you do not
reduce incoming gas pressure, fireplace
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 (equip-
ment 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
requirements 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.
