INSTALLATION

Continued

CAUTION: Never connect pro-

pane/LP fireplace directly to the

propane/LP supply. This fireplace

requires an external regulator

(not supplied). Install the external

regulator between the fireplace

and propane/LP supply.

WARNING: Never connect

natural gas fireplace to private

(non-utility) gas wells. This

gas is commonly known as

wellhead gas.

For propane/LP units, 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 18. Pointing the vent down

protects it from freezing rain or sleet.

CAUTION: Use only new,

black iron or steel pipe. Inter-

nally-tinned copper tubing may

be used in certain areas. Check

your local codes. Use pipe of

1/2" or greater diameter to allow

proper gas volume to fireplace.

If pipe is too small, undue loss

of volume will occur.

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 fireplace (see Figure 19).
IMPORTANT:

Install an equipment shutoff valve

in an accessible location. The equipment shutoff

valve is for turning on and shutting off the gas to

the appliance.

Check your building codes for any special re-

quirements for locating equipment shutoff valve

to fireplaces.

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 fireplace valves.

WARNING: Use pipe joint

sealant that is resistant to liquid

petroleum (LP) gas.

We recommend that you install a sediment trap in

supply line as shown in Figure 19. Locate sediment

trap where it is within reach for cleaning. Install in

piping system between fuel supply and fireplace.

Locate sediment trap where trapped matter is not

likely to freeze. A sediment trap traps moisture and

contaminants. This keeps them from going into fire-

place controls. If sediment trap is not installed or is

installed wrong, fireplace may not run properly.

* Purchase the optional CSA design-certified

equipment shutoff valve from your dealer. See

Accessories, page 27.
