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.

WARNING: Never connect

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.
