LFP33NRA

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

• approved flexible gas line with gas con-

nector (if allowed by local codes) (not
provided)

* 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 24 and 25.

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.
