UNVENTED NATURAL GAS FIREPLACE
®
INSTALLING GAS PIPING TO
FIREPLACE LOCATION
Installation Items Needed
Before installing fireplace, make sure you
have the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* A CSA/AGA design-certified equipment
shutoff valve with 1/8" NPT tap is an accept-
able alternative to test gauge connection.
Purchase the optional CSA/AGA design-
certified equipment shutoff valve from your
dealer. See Accessories, pages 22 and 23.
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
WARNING: Never connect
fireplace to private (non-utility)
gas wells. This gas is commonly
known as wellhead gas.
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
pressure will occur.
