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"
diameter or greater to allow
proper gas volume to fireplace. If
pipe is too small, undue loss of
volume will occur.
INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
CAUTION: Never connect
heater directly to the propane/LP
supply. This heater requires an ex-
ternal regulator (not supplied). In-
stall the external regulator between
the heater and propane/LP supply.

Installation Items Needed
Before installing fireplace, 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 (optional)
• tee joint
• pipe wrench
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the optional CSA design-certified
equipment shutoff valve from your dealer.
See Accessories, pages 22 and 23.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incoming gas pressure to between 11 and 14
inches of water. If you do not reduce incom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
17. Pointing the vent down protects it from
freezing rain or sleet.
WARNING: This appliance re-
quires a 1/2" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.
