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 heater (see Figure 20).

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 require-
ments for locating equipment shutoff valve to fire-
places.

Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from go-
ing 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.

CONNECTING TO GAS SUPPLY

 WARNING: This appliance re-

quires a 45° male flare fitting 5/8"-
18 UNF (Unified National Fine
Thread) inlet connection and the
flexible gas line provided.

 WARNING: A qualified service

person must connect fireplace to
gas supply. Follow all local codes.

 WARNING: Never connect

natural gas fireplace to private
(non-utility) gas wells. This gas is
commonly known as wellhead gas.

IMPORTANT:

 For natural gas, check gas line pressure

before connecting fireplace to gas line. Gas line pressure
must be no greater than 14 inches of water. If gas line
pressure is higher, heater regulator damage could occur.

 CAUTION: Never connect pro-

pane/LP fireplace directly to the
propane/LP supply. This fireplace
requires an external regulator (not
supplied). Install the external regu-
lator between the fireplace and
propane/LP supply.

For propane/LP units, the installer must supply an
external regulator. The external regulator will re-
duce incoming gas pressure. You must reduce in-
coming gas pressure to between 11 and 14 inches
of water. If you do not reduce incoming gas pres-
sure, fireplace regulator damage could occur. In-
stall external regulator with the vent pointing down
as shown in Figure 19. Pointing the vent down
protects it from freezing rain or sleet.

 CAUTION: Use only new, black

iron or steel pipe. Internally-tinned
copper tubing may be used in cer-
tain areas. Check your local codes.
Use pipe of 1/2" or greater diam-
eter to allow proper gas volume to
fireplace. If pipe is too small, un-
due loss of volume will occur.

* Purchase the optional CSA design-certified
equipment shutoff valve from your dealer. See Ac-
cessories,
 pages 38 and 39.
