CHECK GAS TYPE
You must install this ON/OFF Safety Valve/
Pilot Kit if your gas type is propane/LP. For
additional convenience and safety, this ON/
OFF Safety Valve/Pilot Kit can be used with
natural gas. This pilot kit can only be installed
ontherightside(facing)ofthegaslogset.If
you are unsure of the proper application, call
dealer where you bought log set.
Ifthereplacedoesnothaveagassupply
shutoff valve, one must be installed.

Installation Items Needed
Before installing log set, make sure you have
the items listed below.
• piping(checklocalcodes)
• sealant(resistanttopropane/LPgas)
• equipment shutoff valve*
• test gauge connection*
• adjustable(crescent)wrenchorpliers
• sediment trap
• tee joint
• pipe wrench
• exiblegasline
• 10 mm Deep Socket
INSTALLATION
Continued
*A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
theoptionalCSAdesign-certiedequipment
shutoff valve from your dealer.
For propane/LP units, 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, appliance regulator
damage could occur. Install external regula-
tor with the vent pointing down as shown in
Figure 2. Pointing the vent down protects it
from freezing rain or sleet.

Installation must include an equipment shut-
off valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from log
set(seeFigure3).
IMPORTANT: Install equipment shutoff valve
in an accessible location. The equipment
shutoff 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 appliance.
Apply pipe joint sealant lightly to male NPT
threads(notrequiredonaredttings).This
will prevent excess sealant from going into
pipe. Excess sealant in pipe could result in a
cloggedburnerorice.

We recommend that you install a sediment
trap in supply line as shown in Figure 3.
Locate sediment trap where it is within reach
for cleaning. Install in piping system between
fuel supply and appliance. Locate sediment
trap where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into log set controls. If sediment trap is not
installed or is installed wrong, log set may
not run properly.
